WEBVTT 00:00:00.745 --> 00:00:03.162 (soft music) 00:00:05.820 --> 00:00:07.270 Welcome to the California Public 00:00:07.270 --> 00:00:08.410 Utilities Commission 00:00:08.410 --> 00:00:12.110 on this day, Tuesday, April 20th, 2021. 00:00:12.110 --> 00:00:13.490 This is the Pacific Gas 00:00:13.490 --> 00:00:15.578 and Electric Tree Overstrike Workshop. 00:00:15.578 --> 00:00:17.673 Joyce Steingass, you may begin. 00:00:20.240 --> 00:00:22.388 Good morning President Batjer and Commissioners. 00:00:22.388 --> 00:00:26.720 And thank you to everyone who has joined us virtually today. 00:00:26.720 --> 00:00:28.670 The California Public Utilities Commission 00:00:28.670 --> 00:00:32.160 is hosting this public workshop to hear from PG and E 00:00:32.160 --> 00:00:34.109 about impacts of trees that are tall enough 00:00:34.109 --> 00:00:37.620 to fall on electric overhead distribution lines 00:00:37.620 --> 00:00:40.100 and involve tree Overstrike exposure 00:00:40.100 --> 00:00:41.740 that may increase the necessity 00:00:41.740 --> 00:00:44.390 to call public safety power shutoff. 00:00:44.390 --> 00:00:46.600 We understand that Commissioners may attend all 00:00:46.600 --> 00:00:49.780 or part of the session as their schedules allow. 00:00:49.780 --> 00:00:51.770 I am Joyce Steingass, Senior Engineer 00:00:51.770 --> 00:00:54.280 with the CPUC Energy Division. 00:00:54.280 --> 00:00:56.810 I am joined by Tony Noll, Program Manager 00:00:56.810 --> 00:00:59.060 for the Wildfire Safety and Enforcement Branch 00:00:59.060 --> 00:01:01.980 of the CPUC Safety and Enforcement Division. 00:01:01.980 --> 00:01:04.048 Shelby Chaste, Senior Analyst with Tony's branch 00:01:04.048 --> 00:01:06.370 will join me in moderating the questions 00:01:06.370 --> 00:01:08.700 and answers section today. 00:01:08.700 --> 00:01:12.030 Before we get underway, let's welcome our colleagues 00:01:12.030 --> 00:01:16.040 from the California office of Emergency Services 00:01:16.040 --> 00:01:18.610 because we have Mike Masoni, Director of Response 00:01:18.610 --> 00:01:20.010 for the North region. 00:01:20.010 --> 00:01:22.350 And please welcome from the California Department 00:01:22.350 --> 00:01:24.670 of Forestry and Fire Protection, 00:01:24.670 --> 00:01:26.800 Cal FIRE Battalion Chief Jeff Fuentes. 00:01:26.800 --> 00:01:28.470 He is affiliated with Cal FIRE's 00:01:28.470 --> 00:01:31.330 Utility Fire Mitigation Unit. 00:01:31.330 --> 00:01:33.560 We welcome Assistant Director, Masoni 00:01:33.560 --> 00:01:35.873 and Battalion Chief Fuentes to join in the dialogue 00:01:35.873 --> 00:01:38.960 or in the Q and A segment during the panel 00:01:38.960 --> 00:01:41.460 and we appreciate their sharing their knowledge 00:01:41.460 --> 00:01:43.380 and expertise today. 00:01:43.380 --> 00:01:46.950 From PG and E they have a team led by Senior Vice President 00:01:46.950 --> 00:01:49.370 and Chief Risk Officer, Sumeet Singh 00:01:49.370 --> 00:01:51.670 and some of PG and E presenters will include, 00:01:51.670 --> 00:01:55.330 Scott Strenfel, who's PG and E's Chief Meteorologist 00:01:55.330 --> 00:01:57.803 and Manager for Meteorology and Fireside. 00:01:58.700 --> 00:02:00.200 PG and E brought Jake Zigelman 00:02:00.200 --> 00:02:01.890 to speak on customer impacts. 00:02:01.890 --> 00:02:05.130 He's the Senior

00:02:12.990 We appreciate that PG and E has made available 00:02:12.990 --> 00:02:15.200 their executives and experts from their company 00:02:15.200 --> 00:02:17.488 who might join during Q and A. 00:02:17.488 --> 00:02:22.390 So, on the agenda slide, that's inside the deck, 00:02:22.390 --> 00:02:25.700 our agenda for today begins with some background 00:02:25.700 --> 00:02:28.830 followed by PG and E's proposal and rationale. 00:02:28.830 --> 00:02:31.890 We'll hear how PG and E proposes to communicate 00:02:31.890 --> 00:02:35.120 and mitigate the potential for increased frequency 00:02:35.120 --> 00:02:37.460 of public safety power shutoff, 00:02:37.460 --> 00:02:40.250 about customer impact and finally discussing 00:02:40.250 --> 00:02:43.800 the reporting or oversight of these new features. 00:02:43.800 --> 00:02:46.720 On this next slide I'd like to dive into some background 00:02:46.720 --> 00:02:49.853 about why the Commission is holding this workshop today. 00:02:50.940 --> 00:02:52.960 So on the background slide, 00:02:52.960 --> 00:02:57.760 PG and E is undergoing probation stemming from PG and E's 00:02:57.760 --> 00:03:00.400 felony conviction for its involvement 00:03:00.400 --> 00:03:05.280 in the deadly 2010 San Bruno gas pipeline explosion. 00:03:05.280 --> 00:03:07.362 As a condition of this ongoing probation 00:03:07.362 --> 00:03:10.004 the federal court may order PG and E 00:03:10.004 --> 00:03:12.970 to implement new probation condition. 00:03:12.970 --> 00:03:15.040 Probation conditions, 11 and 12, 00:03:15.040 --> 00:03:17.390 which would require PG and E 00:03:17.390 --> 00:03:19.737 to de energize additional distribution lines 00:03:19.737 --> 00:03:23.040 during public safety power shutoff events 00:03:23.040 --> 00:03:25.330 based on the number of trees tall enough 00:03:25.330 --> 00:03:28.090 to fall on the electric distribution line. 00:03:28.090 --> 00:03:32.070 That's based on the tree Overstrike exposure. 00:03:32.070 --> 00:03:35.410 So if ordered by the United States District Court, 00:03:35.410 --> 00:03:39.930 then PG and E would implement these conditions 00:03:39.930 --> 00:03:44.033 by July 1st for this 2021 fire season. 00:03:44.930 --> 00:03:49.190 The CPUC has notified the United States District Court 00:03:49.190 --> 00:03:50.830 about the CPUC's concern 00:03:50.830 --> 00:03:53.490 that these probation conditions would increase the scope 00:03:53.490 --> 00:03:56.970 and frequency of public safety power shutoff. 00:03:56.970 --> 00:04:00.123 So on the next slide we'll cover the workshop purpose. 00:04:01.400 --> 00:04:05.130 This workshop is a forum to present, develop and comment 00:04:05.130 --> 00:04:08.078 on PG and E's proposal to fulfill probation 00:04:08.078 --> 00:04:10.013 conditions, 11 and 12. 00:04:10.920 --> 00:04:13.000 So these conditions are currently proposed 00:04:13.000 --> 00:04:15.570 but they're not yet ordered by the Federal Court. 00:04:15.570 --> 00:04:18.180 PG and E will explain its proposed methodology, 00:04:18.180 --> 00:04:21.320 they'll also explain the impacts and the estimated size 00:04:21.320 --> 00:04:22.953 and number of PSPS events. 00:04:24.070 --> 00:04:28.240 So the format for today's workshop is a moderated panel 00:04:28.240 --> 00:04:31.030 whereby during the agenda we will have questions 00:04:31.030 --> 00:04:33.120 and answers interspersed. 00:04:33.120 --> 00:04:35.040 The Commissioners may direct questions 00:04:35.040 --> 00:04:38.860 to PG and E followed by other panelists 00:04:38.860 --> 00:04:41.730 such as Calloway and Cal FIRE 00:04:41.730 --> 00:04:44.720 and then by our Safety Enforcement Division 00:04:44.720 --> 00:04:47.130 and Energy Division staff. 00:04:47.130 --> 00:04:48.960 So PG and E will answer the questions 00:04:48.960 --> 00:04:52.320 and there could be some dialogue between the panelists. 00:04:52.320 --> 00:04:54.190 These Q and A segments will not be open 00:04:54.190 --> 00:04:56.320 to the public to ask questions. 00:04:56.320 --> 00:04:58.870 At the end of the agenda the operator will open up 00:04:58.870 --> 00:05:01.580 the phone line and will take public comment. 00:05:01.580 --> 00:05:04.399 The operator will take two minute comments 00:05:04.399 --> 00:05:07.010 or statements from the public. 00:05:07.010 --> 00:05:09.530 I wanted to make sure that everyone knows 00:05:09.530 --> 00:05:12.860 that interested parties may serve written comments 00:05:12.860 --> 00:05:15.283 five business days after today's workshop 00:05:15.283 --> 00:05:19.500 through the three service list noticed about this workshop. 00:05:19.500 --> 00:05:24.500 The deadline for written comment is April 27th at 5:00p.m. 00:05:25.040 --> 00:05:28.710 And after the workshop, the CPUC will act appropriately, 00:05:28.710 --> 00:05:31.520 considering the federal probation proceeding 00:05:31.520 --> 00:05:35.250 and the workshop information provided today. 00:05:35.250 --> 00:05:39.150 One caveat that I wanted to offer before we get started 00:05:39.150 --> 00:05:43.780 is that the onscreen presentation will be minorly different 00:05:44.920 --> 00:05:48.070 from that served to the service list yesterday. 00:05:48.070 --> 00:05:50.018 A revised version has been uploaded 00:05:50.018 --> 00:05:55.018 just this morning to the CPUC's PSPS webpage. 00:05:55.760 --> 00:05:59.400 We will send a listing to the service list 00:05:59.400 --> 00:06:01.210 after the workshop ends 00:06:01.210 --> 00:06:04.133 to make a note to which slides changed. 00:06:06.150 --> 00:06:09.380 So with that, let's turn the mic over 00:06:09.380 --> 00:06:11.980 to Sumeet Singh from PG and E. 00:06:11.980 --> 00:06:15.150 He will provide background including excerpts 00:06:15.150 --> 00:06:19.110 of the probation conditions and some overview information 00:06:19.110 --> 00:06:23.470 about the PSPS decision-making criteria and process 00:06:23.470 --> 00:06:28.470 and about tree related risks, including tree overstrike. 00:06:28.850 --> 00:06:30.623 So let's turn to that now. 00:06:32.560 --> 00:06:35.860 Great, good morning, Joyce. 00:06:35.860 --> 00:06:37.770 Just confirming and doing a mic check. 00:06:37.770 --> 00:06:38.603 Can you hear me? 00:06:41.010 --> 00:06:41.843 Excellent. 00:06:41.843 --> 00:06:43.360 All right. Good morning, President Batjer 00:06:43.360 --> 00:06:44.596 and respect to Commissioners. 00:06:44.596 --> 00:06:46.890 My name is Sumeet Singh and I have the privilege 00:06:46.890 --> 00:06:49.952 of being PG and E's Chief Risk Officer. 00:06:49.952 --> 00:06:51.928 And we really appreciate your time in today's forum 00:06:51.928 --> 00:06:56.430 to discuss the 2021 public safety power shutoff program 00:06:56.430 --> 00:07:00.130 and the proposed updates to the shutoff criteria 00:07:00.130 --> 00:07:02.270 that are under consideration. 00:07:02.270 --> 00:07:03.103 As we all know, 00:07:03.103 --> 00:07:05.020 California continues to experience an increase 00:07:05.020 --> 00:07:08.100 in low fire risk and a longer wildfire season. 00:07:08.100 --> 00:07:10.560 We're meeting with you today with a shared goal 00:07:10.560 --> 00:07:12.940 of keeping our customers and our communities 00:07:12.940 --> 00:07:15.480 that we're privileged to serve safe. 00:07:15.480 --> 00:07:17.609 We know that losing power disrupts lives 00:07:17.609 --> 00:07:20.170 and we have been focused on reducing 00:07:20.170 --> 00:07:23.235 the impact of PSPS events for our customers 00:07:23.235 --> 00:07:25.070 throughout our service territory 00:07:25.070 --> 00:07:27.010 without compromising safety. 00:07:27.010 --> 00:07:28.937 We also know that we need to do more 00:07:28.937 --> 00:07:31.550 and we're committed to doing so. 00:07:31.550 --> 00:07:33.230 Last year was one of the most active 00:07:33.230 --> 00:07:35.050 wildfire seasons on record, 00:07:35.050 --> 00:07:36.200 not just in California, 00:07:36.200 --> 00:07:38.460 but all over the Western United States. 00:07:38.460 --> 00:07:41.530 The effects of climate change are here 00:07:41.530 --> 00:07:45.581 and we have a responsibility to do everything we can 00:07:45.581 --> 00:07:48.159 to provide electricity in a way that is safe 00:07:48.159 --> 00:07:49.693 in our new climate. 00:07:50.660 --> 00:07:55.230 After each PSPS event and after each wildfire season, 00:07:55.230 --> 00:07:57.160 we review the wildfire conditions 00:07:57.160 --> 00:07:59.700 and the damages experienced to our system 00:07:59.700 --> 00:08:01.668 and incorporate lessons learned 00:08:01.668 --> 00:08:05.620 to continue to evolve our PSPS program. 00:08:05.620 --> 00:08:08.060 We've also been in discussions with the Federal Court 00:08:08.060 --> 00:08:10.390 providing oversight over probation conditions 00:08:10.390 --> 00:08:14.780 about additional proposed criteria for the PSPS program 00:08:14.780 --> 00:08:17.070 that accounts for outstanding pre-work 00:08:17.070 --> 00:08:19.880 and also trees that are tall enough to strike 00:08:19.880 --> 00:08:21.260 the distribution power lines. 00:08:21.260 --> 00:08:23.580 And that's really at the heart of the discussion 00:08:23.580 --> 00:08:25.510 that we're gonna have today. 00:08:25.510 --> 00:08:27.530 We look forward to working with you 00:08:27.530 --> 00:08:29.290 on these proposed conditions 00:08:29.290 --> 00:08:31.610 and ensure that we're taking the appropriate steps 00:08:31.610 --> 00:08:33.090 for the safety of our customers 00:08:33.090 --> 00:08:35.080 and our communities that we serve. 00:08:35.080 --> 00:08:38.690 We understand that the criteria are still under development 00:08:38.690 --> 00:08:40.947 and we will continue to work closely with this Commission 00:08:40.947 --> 00:08:43.620 and the Federal Court on a path forward 00:08:43.620 --> 00:08:45.750 as final decisions are made. 00:08:45.750 --> 00:08:47.647 We have presentation materials that we will review today 00:08:47.647 --> 00:08:50.130 and we look forward to answering any questions 00:08:50.130 --> 00:08:51.133 that you may have. 00:08:52.080 --> 00:08:55.220 So just a quick recap of who else is here 00:08:55.220 --> 00:08:56.540 joining me today. 00:08:56.540 --> 00:08:58.910 Scott Strenfel, who is our chief meteorologist. 00:08:58.910 --> 00:09:03.010 Aaron Johnson, who is our Vice President of Wildfire Safety, 00:09:03.010 --> 00:09:04.980 Michael Ritter, who's a senior director 00:09:04.980 --> 00:09:08.270 of PG and E's Management Program. 00:09:08.270 --> 00:09:10.880 Jake Zigelman who's leading our local customer 00:09:10.880 --> 00:09:12.870 experience team and Tracy Maratukulum 00:09:12.870 --> 00:09:14.770 who is the responsible director 00:09:14.770 --> 00:09:16.860 for our PSPS program overall. 00:09:16.860 --> 00:09:19.190 So with that, I will begin walking through the materials. 00:09:19.190 --> 00:09:21.783 So if we can go to the next slide, please. 00:09:27.720 --> 00:09:28.623 One more please. 00:09:30.890 --> 00:09:32.600 Perfect. Thank you. 00:09:32.600 --> 00:09:34.830 So the public safety power shutoff program launched 00:09:34.830 --> 00:09:38.910 in 2018 and every year the program has evolved 00:09:38.910 --> 00:09:42.090 in important ways to respond to the increasing wildfire risk 00:09:42.090 --> 00:09:45.060 and lessons learned from the prior year. 00:09:45.060 --> 00:09:48.000 In 2019, following the Camp Fire, 00:09:48.000 --> 00:09:51.390 we expanded the scope to include transmission lines 00:09:51.390 --> 00:09:54.510 but we failed to scale our notifications, 00:09:54.510 --> 00:09:56.500 website and customer support 00:09:57.340 --> 00:10:01.710 and our execution required significant improvements. 00:10:01.710 --> 00:10:04.480 Last year, we improved on nearly every facet 00:10:04.480 --> 00:10:06.130 of our customer and community support, 00:10:06.130 --> 00:10:09.523 significantly reducing the number and size of PSPS events. 00:10:10.560 --> 00:10:12.820 After the wildfires we all saw last year 00:10:12.820 --> 00:10:16.298 we know that we have to be even more diligent 00:10:16.298 --> 00:10:21.040 and vigilant as part of this year's fire season. 00:10:21.040 --> 00:10:22.690 Given the ongoing drought, 00:10:22.690 --> 00:10:24.400 the lengthening of the fire season 00:10:24.400 --> 00:10:25.940 and ever evolving conditions, 00:10:25.940 --> 00:10:28.763 we will not take any chances with customer safety. 00:10:30.340 --> 00:10:32.123 If we can go to the next slide, please. 00:10:34.000 --> 00:10:37.320 Judge Alsup, a federal judge that is overseeing 00:10:37.320 --> 00:10:40.700 our probation is considering additional conditions 00:10:40.700 --> 00:10:43.000 that would require us to turn off power 00:10:43.000 --> 00:10:45.400 when certain criteria are met 00:10:45.400 --> 00:10:48.780 with regards to outstanding tree work 00:10:48.780 --> 00:10:52.590 and also trees near distribution power lines. 00:10:52.590 --> 00:10:55.053 The initial proposed conditions, 00:10:56.927 --> 00:10:59.010 in the Judge Alsup conditions referenced 00:10:59.010 --> 00:11:03.360 the nomenclature of none, few, average and many 00:11:03.360 --> 00:11:05.270 in relationship to the characterization 00:11:05.270 --> 00:11:09.340 of overstrike potential trees that are in close proximity 00:11:09.340 --> 00:11:11.410 to our distribution power lines. 00:11:11.410 --> 00:11:13.310 The proposed approach that we're gonna walk through 00:11:13.310 --> 00:11:16.757 in detail is consistent with this intent 00:11:16.757 --> 00:11:19.867 and is based on an objective criteria 00:11:19.867 --> 00:11:22.655 and we'll also discuss the basis of that criteria 00:11:22.655 --> 00:11:24.663 that enables a consistent 00:11:24.663 --> 00:11:28.250 and repeatable PSPS scoping process. 00:11:28.250 --> 00:11:30.970 While these conditions are still under consideration 00:11:30.970 --> 00:11:34.480 and not final, we're preparing now in case we're required 00:11:34.480 --> 00:11:36.920 to change the criteria of the PSPS program 00:11:36.920 --> 00:11:38.870 heading into this year. 00:11:38.870 --> 00:11:40.770 If we can go to the next slide please? 00:11:43.440 --> 00:11:47.863 Before we get into more detail regarding these conditions, 00:11:47.863 --> 00:11:51.980 I'll just step back and provide a quick overview 00:11:51.980 --> 00:11:54.513 of our existing vegetation management programs. 00:11:55.430 --> 00:11:58.560 In summary, we have two primary programs. 00:11:58.560 --> 00:12:02.090 One is what we call a routine vegetation management program 00:12:02.090 --> 00:12:04.500 that is a requirement for the State of California 00:12:04.500 --> 00:12:07.410 that's covered under General Order 95 00:12:07.410 --> 00:12:09.410 in the public resource code. 00:12:09.410 --> 00:12:11.270 It requires that we maintain 00:12:11.270 --> 00:12:13.510 a minimum of four foot clearance 00:12:13.510 --> 00:12:15.140 around our distribution power lines 00:12:15.140 --> 00:12:17.713 and high fire threat areas year round. 00:12:18.760 --> 00:12:20.930 Our enhanced vegetation management program 00:12:20.930 --> 00:12:22.470 which is the graphic that you see on the right-hand side 00:12:22.470 --> 00:12:27.030 of that slide is an extra safety step that we take 00:12:27.030 --> 00:12:30.140 to clear vegetation above the power lines 00:12:30.140 --> 00:12:32.010 from the conductor to the sky 00:12:32.010 --> 00:12:36.120 so we minimize any potential fall vegetation 00:12:36.120 --> 00:12:37.200 that may be overhanging 00:12:37.200 --> 00:12:40.140 on top of our distribution of overhead lines. 00:12:40.140 --> 00:12:43.980 We also address dead, dying, deceased trees 00:12:43.980 --> 00:12:47.300 which we've seen uptake of given the drought conditions 00:12:47.300 --> 00:12:50.120 and the mortality of trees that are tall enough to fall 00:12:50.120 --> 00:12:53.000 within our overhead distribution lines. 00:12:53.000 --> 00:12:54.980 And then also we assess as part 00:12:54.980 --> 00:12:57.210 of our enhanced vegetation management, 00:12:57.210 --> 00:13:00.020 trees that are tall enough to strike a distribution line 00:13:00.020 --> 00:13:03.670 that could pose an increased wildfire risk. 00:13:03.670 --> 00:13:06.770 Although they may be healthy but have a significant defect 00:13:06.770 --> 00:13:09.510 that deems them to be a higher risk tree 00:13:09.510 --> 00:13:10.860 that needs to be mitigated. 00:13:12.100 --> 00:13:13.230 One clarification 00:13:13.230 --> 00:13:15.290 that enhanced vegetation management program 00:13:15.290 --> 00:13:19.000 does not mitigate a potential blow in risk 00:13:19.000 --> 00:13:22.790 where we may have a tree limb that's 40 or 50 feet away 00:13:22.790 --> 00:13:24.630 from the power line that can break off 00:13:24.630 --> 00:13:27.130 and fly into the line during periods 00:13:27.130 --> 00:13:28.940 of high wind conditions. 00:13:28.940 --> 00:13:31.360 Significant level of focus there for us 00:13:31.360 --> 00:13:33.280 is our system hardening program 00:13:33.280 --> 00:13:36.420 which is the overhead conductor or undergrounding 00:13:36.420 --> 00:13:39.170 which we've spoken in a similar forum 00:13:39.170 --> 00:13:40.520 with this Commission about. 00:13:41.360 --> 00:13:44.421 I do wanna note that we will be evaluating 00:13:44.421 --> 00:13:48.290 if excluding circuits, where we have performed 00:13:48.290 --> 00:13:50.070 the enhancement attrition management 00:13:50.070 --> 00:13:52.635 given the health assessment of potential fallen trees 00:13:52.635 --> 00:13:57.450 from the proposed three overstride criteria is appropriate, 00:13:57.450 --> 00:14:00.140 we're still going through the analysis phase of this 00:14:00.140 --> 00:14:02.060 based on reviewing the circuit performance 00:14:02.060 --> 00:14:05.640 pre and post EVM mitigation work. 00:14:05.640 --> 00:14:08.160 So just to put things in context, 00:14:08.160 --> 00:14:11.703 out of the 25,500 miles of overhead distribution lines 00:14:11.703 --> 00:14:15.960 that we have that traversed our high fire threat districts 00:14:15.960 --> 00:14:18.210 between 2019 and 2020, 00:14:18.210 --> 00:14:21.089 we've completed enhanced vegetation management work 00:14:21.089 --> 00:14:26.089 of approximately 4,300 miles out of 25,500 miles. 00:14:28.780 --> 00:14:30.580 If we can do the next slide, please? 00:14:33.250 --> 00:14:34.083 Thank you. 00:14:35.030 --> 00:14:38.730 The proposed conditions requires that we consider trees 00:14:38.730 --> 00:14:40.900 that are further away from our power lines. 00:14:40.900 --> 00:14:44.520 In essence, any tree that's tall enough but not far enough 00:14:44.520 --> 00:14:47.950 from our overhead lines that may be outside our easements 00:14:47.950 --> 00:14:50.290 and our right-of-ways when making the decision 00:14:50.290 --> 00:14:55.290 to turn off power and also includes healthy trees 00:14:55.390 --> 00:14:59.240 that could potential have that fall in risk. 00:14:59.240 --> 00:15:01.277 This means that compared to last year 00:15:01.277 --> 00:15:03.703 under similar weather conditions, 00:15:04.850 --> 00:15:06.903 our customers will live in areas of the high density 00:15:06.903 --> 00:15:09.300 of trees that are tall enough 00:15:09.300 --> 00:15:10.530 to strike the distribution lines 00:15:10.530 --> 00:15:13.457 may experience more frequent PSPS events. 00:15:13.457 --> 00:15:16.240 And we're gonna go through a specific example 00:15:16.240 --> 00:15:18.210 for one of the counties and we will talk about 00:15:18.210 --> 00:15:22.560 the specific impacts regarding the frequency of events, 00:15:22.560 --> 00:15:26.120 our estimated impact of the duration of the events, 00:15:26.120 --> 00:15:29.770 and also the scope on a permanent basis. 00:15:29.770 --> 00:15:33.010 And again, I would like to reinforce that discussions 00:15:34.370 --> 00:15:37.460 with the court and this Commission are ongoing. 00:15:37.460 --> 00:15:39.180 We're looking at carefully 00:15:39.180 --> 00:15:42.160 at how this may impact our customers and our communities 00:15:42.160 --> 00:15:45.290 and we're sharing the community specific information 00:15:45.290 --> 00:15:46.933 regarding the potential impacts. 00:15:47.880 --> 00:15:49.830 If we can go to the next slide, please? 00:15:55.540 --> 00:15:58.490 This slide shows the way that we're calculating 00:15:58.490 --> 00:16:02.913 what we call tree over strike exposure potential. 00:16:04.340 --> 00:16:05.850 When I transition to Scott Strenfel's, 00:16:05.850 --> 00:16:09.919 he will build on this concept on how we've incorporated this 00:16:09.919 --> 00:16:14.480 as part of our proposed decision making criteria. 00:16:14.480 --> 00:16:17.940 So the way we calculate this value is we measure the height 00:16:17.940 --> 00:16:22.700 of the tree and we compare it to the distance of that tree 00:16:22.700 --> 00:16:27.410 from the line which is what's referenced as the 3D distance 00:16:29.160 --> 00:16:32.190 and we're able to assess the overstrike potential 00:16:32.190 --> 00:16:34.030 of individual trees itself. 00:16:34.030 --> 00:16:36.157 So think about height of the tree, 00:16:36.157 --> 00:16:38.140 the distance that it falls, 00:16:38.140 --> 00:16:40.266 and then that remaining distance of the point of contact 00:16:40.266 --> 00:16:43.620 of the tree to the overhead line to the top of the height 00:16:43.620 --> 00:16:45.547 of the tree is what's deemed 00:16:45.547 --> 00:16:49.033 as the tree over strike exposure potential. 00:16:50.870 --> 00:16:53.160 What is shown on the right-hand side of the slide 00:16:53.160 --> 00:16:55.400 is some elements of the criteria. 00:16:55.400 --> 00:16:58.044 And Scott's gonna walk through this in detail 00:16:58.044 --> 00:17:03.044 on how we came up with a threshold of the 70th percentile 00:17:03.780 --> 00:17:06.050 and this really refers to trees 00:17:06.050 --> 00:17:08.250 with the highest overstrike potential 00:17:08.250 --> 00:17:10.420 in a given geographic area. 00:17:10.420 --> 00:17:12.330 And we'll talk about this in a little bit more detail 00:17:12.330 --> 00:17:14.450 as you build on this concept. 00:17:14.450 --> 00:17:16.980 We're also proposing to consider 00:17:16.980 --> 00:17:20.800 both outstanding priority one trees 00:17:20.800 --> 00:17:24.549 which could potentially pose an immediate safety risk 00:17:24.549 --> 00:17:29.549 or priority two trees that require expedited safety work 00:17:29.647 --> 00:17:32.720 as part of the PSPS criteria. 00:17:32.720 --> 00:17:34.689 Now, both priority one and priority two trees 00:17:34.689 --> 00:17:37.230 are part of our normal course 00:17:37.230 --> 00:17:39.840 of the vegetation management work that we do 00:17:39.840 --> 00:17:43.440 and we address the priority one trees within 24 hours 00:17:43.440 --> 00:17:47.240 and priority two trees within 30 days, respectively. 00:17:47.240 --> 00:17:50.680 As part of the impact 00:17:50.680 --> 00:17:52.970 from priority one and priority two trees, 00:17:52.970 --> 00:17:56.890 we do not anticipate the significant impact 00:17:56.890 --> 00:17:58.950 and the reason why I say that 00:17:58.950 --> 00:18:03.210 is because as we forecast adverse weather, 00:18:03.210 --> 00:18:06.470 that's 72 plus hours out that could trigger 00:18:06.470 --> 00:18:08.720 a potential PSPS event, 00:18:08.720 --> 00:18:12.830 we have the ability to overlay our open priority one 00:18:12.830 --> 00:18:15.730 and priority two vegetation management tags 00:18:15.730 --> 00:18:20.620 and deploy our vegetation management crews to safely address 00:18:20.620 --> 00:18:25.070 and mitigate and remediate those open priority one tags 00:18:25.070 --> 00:18:29.600 thereby removing those circuits from the scope of the work. 00:18:29.600 --> 00:18:32.320 The largest impact that we're gonna talk about 00:18:32.320 --> 00:18:34.750 is primarily driven by 00:18:34.750 --> 00:18:37.493 the tree overstrike enclosure potential. 00:18:40.339 --> 00:18:42.200 So if you go to the next slide, 00:18:42.200 --> 00:18:46.620 we start to get into the process that we've used 00:18:46.620 --> 00:18:49.533 by which we have captured the trees 00:18:49.533 --> 00:18:51.440 that are tall enough but not far enough 00:18:51.440 --> 00:18:56.310 from a distribution lines and we have analyzed that data set 00:18:56.310 --> 00:18:59.390 to help formulate the calculation 00:18:59.390 --> 00:19:00.900 of the tree overstrike potential 00:19:00.900 --> 00:19:03.160 that I discussed in the last slide. 00:19:03.160 --> 00:19:06.240 So in 2019 and 2020, 00:19:06.240 --> 00:19:09.880 as part of our enhanced vegetation management program, 00:19:09.880 --> 00:19:13.330 we utilized aerial LiDAR imagery, 00:19:13.330 --> 00:19:15.860 a commercially available technology 00:19:15.860 --> 00:19:17.643 that's tried and tested and proven 00:19:17.643 --> 00:19:20.950 to identify trees that may be tall enough 00:19:20.950 --> 00:19:22.649 to strike our distribution lines 00:19:22.649 --> 00:19:25.750 in the high fire threat areas. 00:19:25.750 --> 00:19:30.310 We conducted the survey over the entire distribution system 00:19:30.310 --> 00:19:33.690 which covers the 25,500 line miles 00:19:33.690 --> 00:19:38.390 and through the survey we determined and identified more 00:19:38.390 --> 00:19:42.720 than 5.3 million trees that could strike 00:19:42.720 --> 00:19:46.196 a potential distribution line if it falls into it 00:19:46.196 --> 00:19:49.827 during severe weather in the high fire threat districts. 00:19:49.827 --> 00:19:54.580 But that's the process by which we obtained that data set 00:19:54.580 --> 00:19:57.940 and collected that data set of strike potential trees 00:19:57.940 --> 00:20:01.500 and through that same process we analyzed 00:20:01.500 --> 00:20:06.500 and got a third party that does this work to help analyze 00:20:06.690 --> 00:20:11.270 what that tree strike overstrike potential distance 00:20:11.270 --> 00:20:14.510 calculation is, that I just walked through. 00:20:14.510 --> 00:20:18.030 So this was done and this data set was available middle 00:20:18.030 --> 00:20:20.650 of last year which is the data set that we're incorporating 00:20:20.650 --> 00:20:24.083 as part of this analysis in the proposed criteria. 00:20:25.370 --> 00:20:27.230 The last slide I'll cover and then I'll pause 00:20:27.230 --> 00:20:30.163 for any questions before I hand it off to Scott. 00:20:31.200 --> 00:20:36.140 Our team has carefully analyzed the LIDAR data 00:20:36.140 --> 00:20:38.560 that was collected and we now have a database 00:20:38.560 --> 00:20:39.723 of the approximate number of trees 00:20:39.723 --> 00:20:42.350 that are located near our distribution lines. 00:20:42.350 --> 00:20:44.830 Like any dataset it's important to understand 00:20:44.830 --> 00:20:47.500 how the information was collected 00:20:47.500 --> 00:20:50.890 in order to make it operational and actionable. 00:20:50.890 --> 00:20:53.000 So in the case of our LIDAR data, 00:20:53.000 --> 00:20:55.520 there are certain dense tree canopies 00:20:55.520 --> 00:20:58.980 that can make it challenging to accurately identify 00:20:58.980 --> 00:21:01.570 where the tree trunks are located. 00:21:01.570 --> 00:21:04.060 That's really how LIDAR works, 00:21:04.060 --> 00:21:08.040 to be able to help identify the location of the tree trunk, 00:21:08.040 --> 00:21:10.300 the location of the tree top that provides 00:21:10.300 --> 00:21:14.110 the height measurement and then the spatial distance 00:21:14.110 --> 00:21:17.940 that's measured on how far a tree is 00:21:17.940 --> 00:21:20.017 from our overhead distribution lines. 00:21:20.017 --> 00:21:23.540 So this means that we identify the overstrike potential 00:21:23.540 --> 00:21:24.810 through the tree tops. 00:21:24.810 --> 00:21:27.600 In some cases where there's a tree canopies 00:21:27.600 --> 00:21:28.910 because of that overhang issue, 00:21:28.910 --> 00:21:30.820 that we're on the process of clearing 00:21:30.820 --> 00:21:33.430 as part of our enhancement vegetation management program, 00:21:33.430 --> 00:21:35.290 and in some of these areas 00:21:35.290 --> 00:21:39.040 there may be overstrike potential that's overestimated 00:21:39.040 --> 00:21:41.980 or underestimated in our database 00:21:41.980 --> 00:21:46.120 but using the aerial LiDAR dataset with a sound approach 00:21:46.120 --> 00:21:48.030 to provide a relative comparison 00:21:48.030 --> 00:21:49.780 of the distribution lines 00:21:49.780 --> 00:21:53.370 that have a higher tree overstrike exposure potential 00:21:53.370 --> 00:21:55.250 than other lines within our service territory. 00:21:55.250 --> 00:21:58.320 And this does serve as the best available data set 00:21:58.320 --> 00:22:00.030 to estimate trees that are tall enough 00:22:00.030 --> 00:22:02.910 to potentially strike for distribution power lines. 00:22:02.910 --> 00:22:05.590 So I'll pause there to take any questions 00:22:05.590 --> 00:22:09.550 before I transition and hand it off to Scott Strenfel 00:22:09.550 --> 00:22:14.120 who's gonna build on the concepts that I just walked through 00:22:14.120 --> 00:22:16.190 and also review how we're leveraging this data set 00:22:16.190 --> 00:22:18.776 to inform the additions to our PSPS criteria 00:22:18.776 --> 00:22:21.740 that's consistent with the proposed conditions 00:22:21.740 --> 00:22:22.850 by the Federal Court. 00:22:22.850 --> 00:22:25.117 So I'll pause here for any questions. 00:22:32.577 --> 00:22:34.043 Commissioner Shiroma. 00:22:35.440 --> 00:22:37.070 Oh, yes. Thank you. 00:22:37.070 --> 00:22:38.570 Thank you for the presentation 00:22:40.309 --> 00:22:43.220 and you know, all the efforts towards prevention. 00:22:43.220 --> 00:22:48.220 So does PG and E have data on past overstrike 00:22:52.027 --> 00:22:56.010 that actually occurred and the circumstances 00:22:56.010 --> 00:22:57.763 under which they did occur? 00:22:58.780 --> 00:23:02.310 We do Commissioner and that's actually 00:23:02.310 --> 00:23:06.230 part of our foundational PSPS decision making criteria. 00:23:06.230 --> 00:23:08.690 So one of the things that we implemented 00:23:08.690 --> 00:23:10.620 and we further enhanced in 2020 00:23:11.740 --> 00:23:14.960 and Scott Strenfel, our chief meteorologist and his team 00:23:14.960 --> 00:23:17.540 are responsible for doing this analysis. 00:23:17.540 --> 00:23:20.253 We have taken a rich data history, 00:23:21.180 --> 00:23:24.740 more than 10 years of data and specifically studying 00:23:24.740 --> 00:23:27.520 the offshore rain pattern with Diablo winds 00:23:27.520 --> 00:23:30.810 that create the potential risk of a PSPS event 00:23:30.810 --> 00:23:34.710 and correlated where we have experienced outages 00:23:34.710 --> 00:23:37.730 to our specific locations in the circuit 00:23:37.730 --> 00:23:39.730 and the drivers of those outages. 00:23:39.730 --> 00:23:43.160 So in some cases it's caused by equipment, 00:23:43.160 --> 00:23:46.310 in other cases it's caused by a tree limb that blows 00:23:46.310 --> 00:23:49.350 into the line and in some cases 00:23:49.350 --> 00:23:52.480 it's caused by a potential falling tree. 00:23:52.480 --> 00:23:55.700 So that historical information is something 00:23:55.700 --> 00:23:59.130 that we call our outage producing wind probability 00:23:59.130 --> 00:24:02.720 and that's a key input in regards to our threshold 00:24:02.720 --> 00:24:04.760 for the PSPS decision-making process. 00:24:04.760 --> 00:24:07.037 And we've had that in place for a couple of years 00:24:07.037 --> 00:24:10.420 and what we're proposing here, Commissioner is, 00:24:10.420 --> 00:24:13.250 even the circuits that have not experienced 00:24:13.250 --> 00:24:16.552 that historical outage but the sheer presence 00:24:16.552 --> 00:24:21.220 of a tree that may be tall enough could introduce 00:24:21.220 --> 00:24:24.850 that additional exposure risk from a overstrike perspective. 00:24:24.850 --> 00:24:27.010 So that's really what the focus 00:24:27.010 --> 00:24:28.510 of this proposed condition is. 00:24:30.220 --> 00:24:31.273 Okay. Thank you. 00:24:31.273 --> 00:24:34.060 So you used historical data, 00:24:34.060 --> 00:24:36.932 looked at the updated weather conditions 00:24:36.932 --> 00:24:41.280 towards the probability of an overstrike. 00:24:42.295 --> 00:24:43.128 Well, thank you. 00:24:46.976 --> 00:24:49.040 Any other questions? 00:24:49.040 --> 00:24:51.140 Yes. Yes please. 00:24:51.140 --> 00:24:54.110 Do you have an estimate of how many 00:24:54.110 --> 00:24:58.003 of your priority one and priority two trees, 00:24:59.940 --> 00:25:01.512 maybe it's the inverse actually. 00:25:01.512 --> 00:25:06.512 But what percentage of the overstrike trees 00:25:07.429 --> 00:25:10.843 are already within your priority one and priority two? 00:25:12.650 --> 00:25:14.840 Commissioner, it's a very small percentage. 00:25:14.840 --> 00:25:16.117 So just to give you... 00:25:16.117 --> 00:25:18.840 And these numbers change obviously on a daily basis, right? 00:25:18.840 --> 00:25:22.310 Because we have more than a thousand pre inspectors 00:25:23.217 --> 00:25:26.760 that are on in assessing our service territory 00:25:26.760 --> 00:25:28.814 as we speak now within the high fire threat districts 00:25:28.814 --> 00:25:31.319 assessing the condition of vegetation, 00:25:31.319 --> 00:25:33.940 given that that condition changes in a dynamic way 00:25:33.940 --> 00:25:38.230 but just to put some numbers and a proxy for you, 00:25:38.230 --> 00:25:42.550 there's less than five at any given point in time 00:25:42.550 --> 00:25:44.700 priority one open tags, 00:25:44.700 --> 00:25:47.860 given that we address those within a 24 hour period. 00:25:47.860 --> 00:25:49.840 So it's a very small number 00:25:49.840 --> 00:25:51.880 which is why I mentioned that, 00:25:51.880 --> 00:25:56.030 you know when we forecast the adverse Diablo wind condition 00:25:56.030 --> 00:25:58.050 as part of a PSPS event, 00:25:58.050 --> 00:25:59.707 you have the ability to be able to safely mobilize 00:25:59.707 --> 00:26:01.810 the vegetation management teams 00:26:01.810 --> 00:26:04.700 and remediate those open priority one tags. 00:26:04.700 --> 00:26:07.090 So we take those issues off the table 00:26:07.090 --> 00:26:10.210 as part of consideration for PSPS criteria. 00:26:10.210 --> 00:26:12.453 In regards to the priority two tags, 00:26:13.320 --> 00:26:16.130 given that that's a 30 day window, 00:26:16.130 --> 00:26:19.990 it's anywhere and in typically within 900 to a thousand. 00:26:19.990 --> 00:26:21.747 And that number again, changes on a on a daily basis 00:26:21.747 --> 00:26:25.161 'cause our teams continue to reduce and identify 00:26:25.161 --> 00:26:27.124 more tags and address these tags. 00:26:27.124 --> 00:26:30.750 It's about 900 to a thousand trees. 00:26:30.750 --> 00:26:33.540 So put that and those numbers 00:26:33.540 --> 00:26:38.540 in context of the 5.3 million strike potential trees. 00:26:39.500 --> 00:26:42.233 So it's a very, very small population. 00:26:44.200 --> 00:26:46.010 Oh, I missed that number earlier. 00:26:46.010 --> 00:26:47.530 That is a tremendous... 00:26:49.260 --> 00:26:51.180 That's an astronomical increase. 00:26:51.180 --> 00:26:52.721 Okay. 00:26:52.721 --> 00:26:54.940 And what about in relation to the circuit? 00:26:54.940 --> 00:26:59.940 So do we have a proportional (indistinct) 00:27:00.230 --> 00:27:03.033 might be getting to that in your next presentation. 00:27:06.660 --> 00:27:09.910 Will you be getting into that? I'm sorry. 00:27:09.910 --> 00:27:11.620 What does that translate into? 00:27:11.620 --> 00:27:15.140 Into how many more circuits will have to be turned off? 00:27:15.140 --> 00:27:18.330 Yes Commissioner, that's part of the next step 00:27:18.330 --> 00:27:20.800 in the process so Scott Strenfel will cover that 00:27:20.800 --> 00:27:22.650 and not only are we gonna discuss 00:27:22.650 --> 00:27:24.830 the potential increase in scope, 00:27:24.830 --> 00:27:29.420 but we will also share the analysis that we've done looking 00:27:29.420 --> 00:27:34.080 at the last 11 years of Diablo wind patterns 00:27:34.080 --> 00:27:39.080 from 2010 to 2020 to identify what the forecast is, 00:27:39.440 --> 00:27:42.860 impact is, to frequency, duration 00:27:42.860 --> 00:27:45.780 and number of customers in smaller events 00:27:45.780 --> 00:27:47.510 versus larger events. 00:27:47.510 --> 00:27:52.510 And as you can logically conclude that the impact 00:27:53.900 --> 00:27:56.960 across our service territory is not uniform. 00:27:56.960 --> 00:27:59.920 So the impact in counties that have a higher number 00:27:59.920 --> 00:28:01.440 of strike potential trees, 00:28:01.440 --> 00:28:04.190 especially in the Northern part of our service territory, 00:28:04.190 --> 00:28:05.740 would experience a greater impact. 00:28:05.740 --> 00:28:08.280 And we'll cover that in more detail. 00:28:08.280 --> 00:28:09.223 Okay. Thank you. 00:28:10.260 --> 00:28:12.730 And then I have a question. 00:28:12.730 --> 00:28:13.873 This is Marybel. 00:28:15.340 --> 00:28:20.174 Did I hear you say 5.5 million trees have been identified? 00:28:20.174 --> 00:28:24.244 Yeah. President Batjer, we've identified an estimated 00:28:24.244 --> 00:28:29.244 from our aerial LiDAR data set, 5.3 million trees 00:28:31.450 --> 00:28:33.230 that are tall enough, 00:28:33.230 --> 00:28:36.920 not far enough from our overhead distribution lines 00:28:36.920 --> 00:28:41.920 and this correlates to 25,500 miles 00:28:42.670 --> 00:28:44.940 of overhead distribution lines that traverse 00:28:44.940 --> 00:28:46.210 the high fire threat districts. 00:28:46.210 --> 00:28:48.040 And we've provided that information 00:28:48.040 --> 00:28:51.360 on slide six with the materials. 00:28:51.360 --> 00:28:54.623 These numbers are inconceivable to me. 00:28:56.450 --> 00:28:59.520 So does that mean that there's a potential 00:28:59.520 --> 00:29:04.520 of you all removing cutting down 5.3 million trees? 00:29:06.570 --> 00:29:08.060 No, it's not President Batjer 00:29:08.060 --> 00:29:11.250 because our enhanced vegetation management program 00:29:11.250 --> 00:29:13.890 does not do clear cutting. 00:29:13.890 --> 00:29:18.073 We don't cut every single strike potential tree, right? 00:29:18.073 --> 00:29:21.236 A tree that's tall enough but not far enough. 00:29:21.236 --> 00:29:24.480 Part of our effort for enhanced vegetation management, 00:29:24.480 --> 00:29:27.050 and this is why we have a significant number 00:29:27.050 --> 00:29:30.300 of qualified, registered arborists 00:29:30.300 --> 00:29:33.720 that identify every single strike potential tree, 00:29:33.720 --> 00:29:37.530 do a 360 hazard assessment, 00:29:37.530 --> 00:29:41.800 and there's a tree assessment tool that we have deployed 00:29:41.800 --> 00:29:45.170 that's been approved certified by our arborist 00:29:45.170 --> 00:29:47.265 that gets gets applied in the field 00:29:47.265 --> 00:29:52.265 and they evaluate things like is that tree on a slope? 00:29:52.970 --> 00:29:56.840 Does that tree have any kind of a potential defect? 00:29:56.840 --> 00:29:58.850 Is it leaning towards the line? 00:29:58.850 --> 00:30:01.500 What is the species of that tree? 00:30:01.500 --> 00:30:05.210 If you think about trees like gray pines that are notorious 00:30:05.210 --> 00:30:07.330 for growing at an angle and if they're growing 00:30:07.330 --> 00:30:09.630 towards a line we know that as it's gonna mature 00:30:09.630 --> 00:30:11.090 especially on a slope, 00:30:11.090 --> 00:30:14.060 that is gonna pose a potential higher risk 00:30:14.060 --> 00:30:15.910 than upon the rows of pine 00:30:15.910 --> 00:30:17.840 that may be growing straight up and down. 00:30:17.840 --> 00:30:21.113 So our professional arborists go out in the field, 00:30:21.113 --> 00:30:23.083 we have more than a thousand. 00:30:32.040 --> 00:30:33.620 Need to remove that tree 00:30:33.620 --> 00:30:35.090 or do we keep that tree in place 00:30:35.090 --> 00:30:36.640 because it's healthy and green. 00:30:37.830 --> 00:30:41.917 Okay. So will this assessment be done by July 1, 00:30:44.410 --> 00:30:47.300 of all these thousands of trees? 00:30:47.300 --> 00:30:49.220 No, I will not President Batjer. 00:30:49.220 --> 00:30:51.554 So this is what we call, 00:30:51.554 --> 00:30:53.740 enhanced vegetation management programs 00:30:53.740 --> 00:30:56.860 that we first implemented in 2019. 00:30:56.860 --> 00:31:01.860 And over 2019 and 2020, we have completed 4,300 miles 00:31:02.950 --> 00:31:05.400 out of the 25,500 00:31:05.400 --> 00:31:09.480 and we're on a pace of completing 1800 plus miles 00:31:09.480 --> 00:31:13.200 every single year over the next five plus years 00:31:13.200 --> 00:31:15.720 to be able to do this assessment. 00:31:15.720 --> 00:31:18.100 And all the while the trees still will grow 00:31:18.100 --> 00:31:20.100 and they will grow, even the small ones 00:31:20.100 --> 00:31:23.310 that are not within the 360, they'll grow. 00:31:23.310 --> 00:31:24.143 I mean. 00:31:26.344 --> 00:31:28.420 So, this is where, President Batjer, 00:31:28.420 --> 00:31:30.740 where, you know, from my perspective, right? 00:31:30.740 --> 00:31:33.495 As the work that's happening we're reducing 00:31:33.495 --> 00:31:38.070 that immediate risk from a strike potential perspective. 00:31:38.070 --> 00:31:39.600 when you look at the overhang, right? 00:31:39.600 --> 00:31:41.810 Because we're also removing all the overhang 00:31:41.810 --> 00:31:44.960 and we've had a history of tree limbs that fall 00:31:44.960 --> 00:31:47.160 into the overhead lines which is a key part 00:31:47.160 --> 00:31:48.990 of our enhanced vegetation management program 00:31:48.990 --> 00:31:51.850 and we're also identifying the weakest link 00:31:51.850 --> 00:31:53.630 of the strike potential trees 00:31:53.630 --> 00:31:57.760 but really the focus of being able to make 00:31:57.760 --> 00:32:01.683 the system more resilient is the system hardening program. 00:32:02.610 --> 00:32:06.870 And that's how we engineer the risk of the system 00:32:06.870 --> 00:32:09.120 to mitigate the fire risk. 00:32:10.124 --> 00:32:10.957 Sounds far more sensible 00:32:10.957 --> 00:32:12.980 than cutting our way out of this by the way. 00:32:12.980 --> 00:32:14.063 Just my opinion. 00:32:15.619 --> 00:32:18.270 So, with where you are, 00:32:18.270 --> 00:32:23.240 in terms of enhanced vegetation management 00:32:23.240 --> 00:32:27.670 and the routine and what we're facing, 00:32:27.670 --> 00:32:29.410 in terms of what you all are facing 00:32:29.410 --> 00:32:32.260 in terms of the court, perhaps 00:32:32.260 --> 00:32:35.393 and the fire season that's confronting us now, 00:32:36.570 --> 00:32:38.720 will that necessitate, 00:32:38.720 --> 00:32:43.530 will where you have not been able to identify the trees 00:32:43.530 --> 00:32:46.510 or have the arborist out checking them. 00:32:46.510 --> 00:32:47.550 You're at 43... 00:32:49.180 --> 00:32:53.490 Anyways, you're not at 25,000 miles, for sure. 00:32:53.490 --> 00:32:56.680 So does that mean you guys are just gonna turn off 00:32:56.680 --> 00:32:57.990 the circuits in those areas 00:32:57.990 --> 00:33:00.383 that you haven't been able to identify? 00:33:01.330 --> 00:33:04.593 When the wind conditions reach the red flag? 00:33:06.160 --> 00:33:11.160 And is that different than what you did in 2020 and 2019? 00:33:13.210 --> 00:33:15.403 Will it be different in 2021? 00:33:16.340 --> 00:33:18.810 It will be, President Batjer 00:33:18.810 --> 00:33:22.010 and you've got that spot on. 00:33:22.010 --> 00:33:26.710 That we're proposing as part of the proposed conditions 00:33:26.710 --> 00:33:31.710 of the Federal Court is to de-energize those circuits 00:33:33.230 --> 00:33:37.770 that have a high number of strike potential trees, 00:33:37.770 --> 00:33:41.410 not at assessed fire and has vegetation management program 00:33:41.410 --> 00:33:44.110 that's when the minimum fire potential conditions 00:33:44.110 --> 00:33:45.150 are there, right? 00:33:45.150 --> 00:33:46.920 Meaning a certain level of threshold, 00:33:46.920 --> 00:33:48.560 the live fuel moisture, 00:33:48.560 --> 00:33:51.030 the dead fuel moisture, red flag warning, 00:33:51.030 --> 00:33:53.710 all the conditions where a potential ignition 00:33:53.710 --> 00:33:55.801 can turn into a catastrophic wildfire. 00:33:55.801 --> 00:34:00.801 That's the additional scope that is being proposed in 2021 00:34:01.450 --> 00:34:04.870 which is different than 2020. 00:34:04.870 --> 00:34:07.710 So it's an additional criteria 00:34:07.710 --> 00:34:09.290 compared to what we had in place. 00:34:09.290 --> 00:34:11.753 And as I was explaining previously, 00:34:11.753 --> 00:34:15.150 based on the question that Commissioner Shiroma asked, 00:34:15.150 --> 00:34:17.303 previously what we've done is we've evaluated 00:34:17.303 --> 00:34:19.832 the performance of the circuit 00:34:19.832 --> 00:34:22.030 based on a certain wind speed. 00:34:22.030 --> 00:34:24.500 And if that circuit has experienced an outage 00:34:24.500 --> 00:34:28.160 which is a leading indicator for a fire ignition, 00:34:28.160 --> 00:34:30.680 that's what we've included in deactivation scope. 00:34:30.680 --> 00:34:34.110 And what we're proposing going into 2021 00:34:34.110 --> 00:34:35.690 is that even though that circuit 00:34:35.690 --> 00:34:38.690 may not have experienced an outage, 00:34:38.690 --> 00:34:43.690 the sheer presence of that over strike exposure 00:34:44.050 --> 00:34:45.520 without having the ability, 00:34:45.520 --> 00:34:47.840 given the scale of trees we're talking about, 00:34:47.840 --> 00:34:51.810 to assess the health of every single one of those trees 00:34:51.810 --> 00:34:55.140 is what's necessitating this additional proposal. 00:34:55.140 --> 00:34:58.350 And we'll talk about the implications of that, that's next. 00:34:58.350 --> 00:35:01.470 Okay. I look forward to hearing more about actually 00:35:01.470 --> 00:35:04.083 the lines and the health of the lines. 00:35:05.160 --> 00:35:08.870 We've had public comments in some of our previous 00:35:08.870 --> 00:35:12.370 perhaps you were, some of your staff may have heard, 00:35:12.370 --> 00:35:14.800 folks that really question. 00:35:14.800 --> 00:35:19.390 And I don't remember the gauge of the wire that they said, 00:35:19.390 --> 00:35:22.540 but some of questions that, you know 00:35:22.540 --> 00:35:25.550 it's not the tree, it's the darn lines that, I mean 00:35:25.550 --> 00:35:29.000 a stick could blow into some of the lines. 00:35:29.000 --> 00:35:33.082 So public comment has been made to us 00:35:33.082 --> 00:35:37.580 because the lines are such a minimal gauge. 00:35:37.580 --> 00:35:41.660 That's not the correct terminology I'm sure, 00:35:41.660 --> 00:35:44.050 but anyway, I look forward to the presentation 00:35:44.050 --> 00:35:46.020 so we can talk about that 00:35:46.020 --> 00:35:51.010 because I don't know how you look at 5.3 million trees 00:35:51.880 --> 00:35:54.040 and continually, continually, continually 00:35:54.040 --> 00:35:56.640 because they grow, thankfully 00:35:56.640 --> 00:35:59.020 and they're dying as you just said 00:35:59.020 --> 00:36:01.780 the mortality rate is increasing 00:36:01.780 --> 00:36:03.397 because of the drought conditions 00:36:03.397 --> 00:36:08.397 and the climate change that we are experiencing. 00:36:08.480 --> 00:36:13.480 So all of this is becoming more advanced on us now. 00:36:15.000 --> 00:36:16.780 So I will stop there. 00:36:16.780 --> 00:36:20.640 I'm sorry for going on so long but thank you. 00:36:20.640 --> 00:36:22.450 No, President Batjer, thank you for your comments. 00:36:22.450 --> 00:36:23.900 We're completely aligned. 00:36:23.900 --> 00:36:26.260 We cannot cut our way out of this issue. 00:36:26.260 --> 00:36:28.750 The intent of the enhanced vegetation management program 00:36:28.750 --> 00:36:32.720 is to have that additional control in place 00:36:32.720 --> 00:36:35.330 on a more immediate basis to identify the weakest trees, 00:36:35.330 --> 00:36:36.850 to address the overhang. 00:36:36.850 --> 00:36:40.460 But the focus is for us to engineer this risk out 00:36:40.460 --> 00:36:43.856 by making the electric grid more resilient, 00:36:43.856 --> 00:36:45.623 not just based on the conditions 00:36:45.623 --> 00:36:47.500 that we're experiencing now, 00:36:47.500 --> 00:36:50.240 but we know that the conditions are gonna worsen over time. 00:36:50.240 --> 00:36:53.250 So that's exactly the focus that we have 00:36:53.250 --> 00:36:55.150 as part of this effort. 00:36:55.150 --> 00:36:58.350 In regards to the comment regarding the small wire, right? 00:36:58.350 --> 00:37:00.290 A comment that was mentioned. 00:37:00.290 --> 00:37:01.890 There's different technical terms. 00:37:01.890 --> 00:37:02.970 I won't go into that. 00:37:02.970 --> 00:37:07.280 And there's also different material type associated 00:37:07.280 --> 00:37:09.140 with the conductor itself. 00:37:09.140 --> 00:37:11.180 But what I can share with you President Batjer 00:37:11.180 --> 00:37:16.180 is that even if we had a bigger or a larger conductor, 00:37:18.340 --> 00:37:23.340 if that conductor is bare and you have a potential tree 00:37:24.310 --> 00:37:26.740 or branch that comes in contact with it, 00:37:26.740 --> 00:37:29.570 that contact in it and by itself, 00:37:29.570 --> 00:37:33.060 can create a potential arc or spark. 00:37:33.060 --> 00:37:35.260 It does not necessarily have to mean 00:37:35.260 --> 00:37:37.680 that that wire has to hit the ground, 00:37:37.680 --> 00:37:39.560 something called a pitch ground fault 00:37:39.560 --> 00:37:41.570 which creates that ignition 00:37:41.570 --> 00:37:46.000 but that sheer nature of the impact of that tree or limb, 00:37:46.000 --> 00:37:48.810 yes in some cases, results in, 00:37:48.810 --> 00:37:51.660 when you have the smaller wire 00:37:51.660 --> 00:37:54.840 it can create a potential ignition point 00:37:54.840 --> 00:37:57.010 or an arc or a spark and that may be enough 00:37:57.010 --> 00:38:00.150 in these conditions to create that catastrophic fire. 00:38:00.150 --> 00:38:03.130 Hence, the reason why system hardening includes 00:38:03.130 --> 00:38:05.580 that covered conductor because it removes 00:38:05.580 --> 00:38:07.860 that bare wire out of the equation, right? 00:38:07.860 --> 00:38:10.830 When you have that contact you've got a plastic covering 00:38:10.830 --> 00:38:13.500 on that bare conductor that does not allow 00:38:13.500 --> 00:38:16.010 for that arcing or sparks to take place. 00:38:16.010 --> 00:38:19.783 So that's the thought process and intent there. 00:38:21.420 --> 00:38:22.390 Well, this is Joyce 00:38:22.390 --> 00:38:24.700 and I apologize for interrupting. 00:38:24.700 --> 00:38:27.700 I really love the engagement and the rich insights 00:38:27.700 --> 00:38:29.750 and perspectives being shared. 00:38:29.750 --> 00:38:31.340 I'd like the urge us to move on 00:38:31.340 --> 00:38:33.960 to Scott Strenfel's presentation 00:38:33.960 --> 00:38:35.989 after which we can reengage in more questions. 00:38:35.989 --> 00:38:37.600 Thanks again. 00:38:37.600 --> 00:38:38.640 My apologies. 00:38:38.640 --> 00:38:40.440 Go ahead, Scott. The floor is yours. 00:38:43.350 --> 00:38:44.610 Great. Yeah. Good morning, everyone. 00:38:44.610 --> 00:38:46.390 Just wanna do a microphone check. 00:38:46.390 --> 00:38:47.390 Can you all hear me? 00:38:49.380 --> 00:38:51.690 Great. Couple head nods out there. 00:38:51.690 --> 00:38:53.740 So yeah, just to give you a little background 00:38:53.740 --> 00:38:55.610 about you know, myself and my team. 00:38:55.610 --> 00:38:56.830 My name is Scott Strenfel. 00:38:56.830 --> 00:38:58.350 I don't think I've had the privilege 00:38:58.350 --> 00:38:59.710 of meeting all of you yet 00:38:59.710 --> 00:39:03.620 but my background is, you know, I'm a meteorologist 00:39:03.620 --> 00:39:05.690 by education and by training 00:39:07.170 --> 00:39:10.350 and received my Master's degree 00:39:10.350 --> 00:39:13.190 from the San Jose State Fire Weather Research Lab 00:39:13.190 --> 00:39:14.360 over a decade ago. 00:39:14.360 --> 00:39:19.158 So my background is actually in the fire weather space 00:39:19.158 --> 00:39:23.110 and I'm privileged to be a part of a strong team 00:39:23.110 --> 00:39:27.070 at PG and E of operational meteorologists, data scientists, 00:39:27.070 --> 00:39:32.070 data engineers, many of whom have advanced degrees. 00:39:32.130 --> 00:39:36.030 And so, you know, I wanted to provide 00:39:36.030 --> 00:39:37.600 a little bit of a context 00:39:38.870 --> 00:39:42.270 related to what Sumeet mentioned 00:39:42.270 --> 00:39:44.206 and kind of build upon the concepts 00:39:44.206 --> 00:39:46.540 that he's already outlined. 00:39:46.540 --> 00:39:48.180 And so I just wanna caution 00:39:48.180 --> 00:39:50.200 and just let everybody know 00:39:50.200 --> 00:39:52.180 that it's been only two short months 00:39:52.180 --> 00:39:57.180 since Judge Alsup issued his proposed conditions 00:39:57.720 --> 00:40:00.060 and my team has been sprinting 00:40:00.060 --> 00:40:03.500 and trying to understand how to one, operationalize 00:40:03.500 --> 00:40:05.320 those potential proposed conditions 00:40:05.320 --> 00:40:07.740 if they do become conditions, 00:40:07.740 --> 00:40:10.270 as well as understand you know, what that would mean 00:40:10.270 --> 00:40:12.820 in terms of PSPS impact. 00:40:12.820 --> 00:40:15.340 And I'll talk into, you know, 00:40:15.340 --> 00:40:18.790 part of my presentation today is I'll go into detail 00:40:18.790 --> 00:40:23.790 about how we analyze those potential impacts 00:40:24.110 --> 00:40:26.773 to customers by analyzing events in the past. 00:40:27.870 --> 00:40:29.947 I also wanted to, in my introductory comments, 00:40:29.947 --> 00:40:33.725 provide some background of how we actually calculate 00:40:33.725 --> 00:40:36.503 the overstrike feet, if you will, 00:40:39.056 --> 00:40:42.760 and relate it to our weather model grid. 00:40:42.760 --> 00:40:45.430 And I hope I don't lose anybody along the way 00:40:45.430 --> 00:40:48.670 because a lot of what we do is very complicated 00:40:48.670 --> 00:40:50.730 in the weather modeling space 00:40:50.730 --> 00:40:53.770 but hopefully it'll give you enough Intel 00:40:53.770 --> 00:40:56.090 such that you can wrap your mind around exactly 00:40:56.090 --> 00:40:58.650 how we're operationalizing this 00:40:58.650 --> 00:41:03.650 and exactly how we're visualizing the risk every day. 00:41:03.840 --> 00:41:07.340 And so from the LiDAR data itself, 00:41:07.340 --> 00:41:09.080 you can imagine that for each tree 00:41:09.080 --> 00:41:10.800 we're getting a point information 00:41:10.800 --> 00:41:14.330 of the overstrike and, you know, going back 00:41:14.330 --> 00:41:16.420 to some of the Commissioner comments about, you know 00:41:16.420 --> 00:41:20.200 the 5.3 million trees being, you know, 00:41:20.200 --> 00:41:21.908 a quite staggering number, 00:41:21.908 --> 00:41:26.908 each one of those trees has an average overstrike feet 00:41:27.300 --> 00:41:29.923 of about 32 to 33 feet. 00:41:30.870 --> 00:41:34.750 And so when you multiply the average by the total number 00:41:34.750 --> 00:41:37.490 of trees that are out there, 00:41:37.490 --> 00:41:41.843 there's about 170 million feet of overstrike 00:41:41.843 --> 00:41:45.610 as determined from our aerial LiDAR. 00:41:45.610 --> 00:41:47.460 And you can imagine these are, you know 00:41:47.460 --> 00:41:52.460 point data sources points across our grid. 00:41:53.900 --> 00:41:56.280 And so how did we come up with 70th percentile? 00:41:56.280 --> 00:42:00.013 Well, we operate a high resolution weather model, 00:42:00.013 --> 00:42:02.673 very similar to the National Weather Service, 00:42:02.673 --> 00:42:04.260 similar to other IOUs 00:42:05.690 --> 00:42:09.070 and that weather model is at two kilometer resolution. 00:42:09.070 --> 00:42:10.293 So what does that mean? 00:42:10.293 --> 00:42:15.200 That the grid itself is analyzing the weather 00:42:15.200 --> 00:42:18.400 and forecasting weather at two by two kilometers squares. 00:42:18.400 --> 00:42:21.930 It's the largest across the state of California. 00:42:21.930 --> 00:42:26.930 Each square's approximately four kilometers squared areas. 00:42:28.160 --> 00:42:30.950 And so for each of these grid cells 00:42:30.950 --> 00:42:33.940 we aggregated the amount of overstrike 00:42:33.940 --> 00:42:36.600 in each one of these areas. 00:42:36.600 --> 00:42:39.540 We have a little over 10,000 of these boxes, 00:42:39.540 --> 00:42:41.430 these grid cells, if you will 00:42:41.430 --> 00:42:45.230 or where you forecast weather and also have historical data. 00:42:45.230 --> 00:42:48.633 And out of those 10,000, we now have 00:42:48.633 --> 00:42:52.080 and we understand the amounts of overstrike feet 00:42:52.080 --> 00:42:53.940 in each one of those. 00:42:53.940 --> 00:42:57.960 And so we simply can rank them from top to low, 00:42:57.960 --> 00:43:02.687 from top to bottom and look at it in various ways. 00:43:02.687 --> 00:43:04.950 And we can look at the outage relationship 00:43:04.950 --> 00:43:07.620 and history compared to various percentiles. 00:43:07.620 --> 00:43:10.210 And so what we mean today 00:43:10.210 --> 00:43:12.427 when I mentioned 70th percentile 00:43:12.427 --> 00:43:14.520 and that comes up a lot, 00:43:14.520 --> 00:43:16.805 is if we rank those grid cells 00:43:16.805 --> 00:43:21.760 that have overstrike from top to bottom, 00:43:21.760 --> 00:43:26.270 the 70th percentile is essentially we're looking at the top 00:43:26.270 --> 00:43:30.210 or the 70th percentile and above of overstrike exposure. 00:43:30.210 --> 00:43:35.210 So that the very top 30%, if you will, set another way 00:43:35.890 --> 00:43:38.430 of overstrike risk and what that represents for us 00:43:38.430 --> 00:43:39.660 in our weather model domain 00:43:39.660 --> 00:43:44.660 is a fixed geographic area where we have the most amounts 00:43:45.030 --> 00:43:48.513 of vegetation overstrike potential. 00:43:49.890 --> 00:43:51.900 And so just wanted to provide that context. 00:43:51.900 --> 00:43:53.650 I know it's a little bit in the weeds 00:43:53.650 --> 00:43:55.090 a little bit detailed but hopefully 00:43:55.090 --> 00:43:56.470 I didn't lose folks along the way 00:43:56.470 --> 00:43:59.513 and hopefully that made a little bit of sense. 00:44:00.840 --> 00:44:03.600 So if we go into the next slide. 00:44:03.600 --> 00:44:07.280 Before I get into how we utilize 00:44:07.280 --> 00:44:09.245 that 70th percentile geographic area 00:44:09.245 --> 00:44:11.880 I also wanted to provide some context 00:44:12.730 --> 00:44:16.920 around some of the models that we utilize now 00:44:16.920 --> 00:44:20.337 and have utilized and did utilize in 2020 00:44:20.337 --> 00:44:23.110 for public safety power shutoff. 00:44:23.110 --> 00:44:25.900 One of the core models that we use 00:44:25.900 --> 00:44:29.730 is called the Fire Potential Index Model. 00:44:29.730 --> 00:44:33.980 And I'll probably use the acronym FPI moving forward 00:44:33.980 --> 00:44:34.960 in this discussion. 00:44:34.960 --> 00:44:37.720 So that's the fire potential index. 00:44:37.720 --> 00:44:42.580 And the FPI model was developed by my team, 00:44:43.450 --> 00:44:45.540 data scientists working with fire scientists 00:44:45.540 --> 00:44:50.530 and meteorologists to tease out the weather 00:44:50.530 --> 00:44:54.530 and feel kind of signals and predictors 00:44:54.530 --> 00:44:58.160 that lead to large fires across California 00:44:58.160 --> 00:45:01.483 and across the PG and E territory specifically. 00:45:02.421 --> 00:45:04.933 And in order to do this, 00:45:06.870 --> 00:45:08.760 I have to introduce another concept 00:45:08.760 --> 00:45:12.160 called a historical climatology. 00:45:12.160 --> 00:45:15.420 And essentially what that is, is, you know, 00:45:15.420 --> 00:45:18.300 we not only forecast the weather 00:45:18.300 --> 00:45:22.760 at that two kilometer resolution going forward out four days 00:45:22.760 --> 00:45:26.560 so that we can get a sense of upcoming PSPS events, 00:45:26.560 --> 00:45:29.040 upcoming storm events, 00:45:29.040 --> 00:45:31.970 but what we've also done is recreate the weather 00:45:32.950 --> 00:45:35.040 going back 30 years, 00:45:35.040 --> 00:45:38.920 hour by hour at that same resolution. 00:45:38.920 --> 00:45:41.630 We have the weather recreated, 00:45:41.630 --> 00:45:44.930 the dead and live fuel moistures 00:45:44.930 --> 00:45:47.670 and a number of different meteorological parameters 00:45:47.670 --> 00:45:49.481 and parameters around fires 00:45:49.481 --> 00:45:52.360 that I'm not going to get into. 00:45:52.360 --> 00:45:56.960 But essentially we have this very robust data set 00:45:56.960 --> 00:45:59.363 in order to analyze events from the past. 00:46:01.440 --> 00:46:04.450 And just to provide a little bit of context 00:46:04.450 --> 00:46:07.720 and maybe clarity in some similarities of analysis 00:46:07.720 --> 00:46:08.670 that had been done, 00:46:09.550 --> 00:46:11.440 similar to what we're doing here, 00:46:11.440 --> 00:46:14.390 is that the high fire threat district map 00:46:14.390 --> 00:46:19.390 that I think we all know of that was issued 00:46:20.450 --> 00:46:23.470 I believe at the end of 2017 from the CPUC 00:46:23.470 --> 00:46:25.730 was built on a similar concept. 00:46:25.730 --> 00:46:27.290 One of the core data sets in there 00:46:27.290 --> 00:46:31.210 was a reconstruction using high resolution weather modeling 00:46:32.240 --> 00:46:34.230 and a 10 year data set to determine 00:46:34.230 --> 00:46:37.400 the highest risk areas across our landscape 00:46:37.400 --> 00:46:41.623 and where specific, you know, regulations should apply. 00:46:42.590 --> 00:46:46.610 And so with that historic dataset what we're able to do is, 00:46:46.610 --> 00:46:49.330 for every fire that's essentially occurred 00:46:49.330 --> 00:46:52.470 we can analyze it in very great detail. 00:46:52.470 --> 00:46:55.377 Understanding the conditions that happened around ignition, 00:46:55.377 --> 00:46:58.900 the conditions that lead to fires spreading rapidly, 00:46:58.900 --> 00:47:01.650 the conditions that lead to fires not spreading rapidly 00:47:02.670 --> 00:47:03.560 and other things. 00:47:03.560 --> 00:47:06.743 And to that end, we... 00:47:06.743 --> 00:47:08.280 And then fast forward a little bit, 00:47:08.280 --> 00:47:11.750 we essentially constructed 4,000 different fire 00:47:11.750 --> 00:47:13.140 potential index models 00:47:13.140 --> 00:47:17.059 to test various combinations of parameters 00:47:17.059 --> 00:47:21.000 that would be predictive for large fires 00:47:21.000 --> 00:47:23.390 and essentially selected the one 00:47:23.390 --> 00:47:25.860 that worked best for our territory. 00:47:25.860 --> 00:47:28.703 And at a high level it's shown at the right. 00:47:30.020 --> 00:47:32.139 And basically what goes 00:47:32.139 --> 00:47:35.310 into our utility fire potential index model, 00:47:35.310 --> 00:47:37.960 our FPI's weather component, 00:47:37.960 --> 00:47:39.986 wind speed, temperature, relative humidity. 00:47:39.986 --> 00:47:43.313 A fuel component, we look at dead fuel moisture, 00:47:44.420 --> 00:47:49.260 as well as live fuel moisture and a land type components. 00:47:49.260 --> 00:47:52.760 And right now it's broken up into three specific categories 00:47:52.760 --> 00:47:56.180 forest, shrub brush and grass. 00:47:56.180 --> 00:48:00.730 And we found that that was a very good predictor 00:48:00.730 --> 00:48:04.117 where you know, it sort of takes into account the, 00:48:05.670 --> 00:48:10.670 I guess the difficulty or not of containment, right? 00:48:11.220 --> 00:48:15.130 Like grass fires, we found are more easily contained. 00:48:15.130 --> 00:48:19.470 Therefore the FPI that's calculated in grass type lands 00:48:19.470 --> 00:48:22.620 is less than what would be computed in a forest 00:48:22.620 --> 00:48:24.993 just based on their characteristics alone. 00:48:26.563 --> 00:48:31.120 And so I hope that gives you some context of our FPI model. 00:48:31.120 --> 00:48:33.130 And so if we go to the next slide I'll show you 00:48:33.130 --> 00:48:37.040 how the FPI model, which is related to the probability 00:48:37.040 --> 00:48:38.620 of large fires is combined 00:48:38.620 --> 00:48:41.270 with our outage producing wind model 00:48:41.270 --> 00:48:46.023 which is related to the probability of a unplanned, 00:48:46.880 --> 00:48:49.007 sustained and momentary outages, 00:48:49.007 --> 00:48:51.509 which is related to ignitions. 00:48:51.509 --> 00:48:56.509 And here, what we're trying to accomplish is understand 00:48:57.074 --> 00:49:00.020 the probability of an event. 00:49:00.020 --> 00:49:03.260 Meaning the probability of an outage 00:49:03.260 --> 00:49:08.260 on our distribution network that is related to wind 00:49:08.320 --> 00:49:11.160 and understand also the consequence side of things, 00:49:11.160 --> 00:49:12.520 the fire potential index. 00:49:12.520 --> 00:49:15.070 So it's the probability of an event occurred multiplied 00:49:15.070 --> 00:49:18.713 by the fire potential index. 00:49:19.760 --> 00:49:21.970 And the graph on the right shows 00:49:21.970 --> 00:49:25.290 the conceptual framework of how the model essentially works. 00:49:25.290 --> 00:49:27.040 When you multiply these two together 00:49:27.040 --> 00:49:31.927 you can imagine that for every single space in our model, 00:49:34.070 --> 00:49:37.070 we have an output of outage producing winds, 00:49:37.070 --> 00:49:40.150 an output of the fire potential index 00:49:40.150 --> 00:49:44.570 and areas where the outage producing a wind index 00:49:44.570 --> 00:49:46.750 is showing a high value, 00:49:46.750 --> 00:49:48.890 maybe there's high wind speeds, 00:49:48.890 --> 00:49:51.233 there's a high probability of an outage, 00:49:53.238 --> 00:49:55.570 that would, you know, on the y-axis 00:49:55.570 --> 00:49:58.880 that would start to raise the level of OPW. 00:49:58.880 --> 00:50:02.147 And then we also look for the concurrence in both space 00:50:02.147 --> 00:50:06.570 and time of where we have a high fire potential index. 00:50:06.570 --> 00:50:08.830 And if you have the concurrence of both of those 00:50:08.830 --> 00:50:11.430 in the space-time here in the upper right-hand portion 00:50:11.430 --> 00:50:13.707 of the chart where it's typically 00:50:13.707 --> 00:50:16.360 during a Diablo wind event, 00:50:16.360 --> 00:50:17.573 a dry offshore wind event 00:50:17.573 --> 00:50:22.173 that we see these two models kind of coming together. 00:50:23.690 --> 00:50:27.430 And essentially we don't have it plotted here 00:50:27.430 --> 00:50:30.270 but a lot of our large catastrophic fires 00:50:30.270 --> 00:50:35.270 in the past in California, Tubs, Nuns, Atlas, 00:50:35.990 --> 00:50:38.121 you know, the the list continues, 00:50:38.121 --> 00:50:41.370 are in that upper right portion of the chart. 00:50:41.370 --> 00:50:43.340 So we can plot all of our fires kind of 00:50:43.340 --> 00:50:44.713 in this space as well. 00:50:47.340 --> 00:50:51.430 I forgot to mention how OPW was constructed 00:50:51.430 --> 00:50:54.110 and one thing I also forgot to mention 00:50:54.110 --> 00:50:57.060 which I'll circle back to is that a discussion 00:50:57.060 --> 00:51:01.090 about these models can also be found 00:51:01.090 --> 00:51:05.250 on our Public 2021 Wildfire Mitigation Plan. 00:51:05.250 --> 00:51:06.610 I believe it's covered in depth 00:51:06.610 --> 00:51:09.900 in Section 4.2.A in that plan. 00:51:09.900 --> 00:51:12.630 So I encourage you all to, if you don't have... 00:51:12.630 --> 00:51:14.374 If I've not given you enough information, 00:51:14.374 --> 00:51:16.760 much more information is provided there 00:51:16.760 --> 00:51:19.083 and you can go through it at your own pace. 00:51:20.905 --> 00:51:24.731 And then stepping into how the outage producing wind model 00:51:24.731 --> 00:51:27.000 was constructed. 00:51:27.000 --> 00:51:30.190 Essentially, it's also a machine learning model 00:51:30.190 --> 00:51:35.190 similar to the fire potential index and going back 10 years 00:51:35.760 --> 00:51:38.930 essentially we can extract the wind speeds 00:51:38.930 --> 00:51:42.030 from our robust historical dataset 00:51:42.030 --> 00:51:45.873 and upend those to every single outage that has happened. 00:51:46.710 --> 00:51:51.710 We also supplemented the model in 2019 with all the damages 00:51:52.140 --> 00:51:54.890 and hazards that happen during PSPS events 00:51:54.890 --> 00:51:58.660 and so we get a sense and we can tease out, you know, 00:51:58.660 --> 00:52:02.670 really what is the wind to outage relationship 00:52:02.670 --> 00:52:04.761 across the PG and E territory. 00:52:04.761 --> 00:52:09.730 And because of the, you know the uniqueness of California, 00:52:09.730 --> 00:52:13.040 uniqueness of Northern California specifically, 00:52:13.040 --> 00:52:16.050 those relationships are heterogeneous across the territory. 00:52:16.050 --> 00:52:18.910 And me and my team, you know every time 00:52:18.910 --> 00:52:22.860 there's a storm event one of us is up monitoring the... 00:52:22.860 --> 00:52:24.760 And this could be a winter storm or anything 00:52:24.760 --> 00:52:27.850 but one of us is typically up monitoring the winds 00:52:27.850 --> 00:52:30.640 and the outage response 'cause we're also responsible 00:52:30.640 --> 00:52:32.900 for our storm outage prediction program 00:52:32.900 --> 00:52:37.480 which forecast outage activity and get crews out 00:52:37.480 --> 00:52:39.670 in front of storms to mitigate 00:52:39.670 --> 00:52:41.440 the impacts for many unplanned outage 00:52:41.440 --> 00:52:44.320 but we've spent a lot of time looking at, 00:52:44.320 --> 00:52:49.070 you know, what wind speeds start to create outage activity 00:52:49.070 --> 00:52:50.533 just across our grid. 00:52:52.660 --> 00:52:56.390 And so, yeah, I hope that provides some context of how 00:52:56.390 --> 00:53:00.370 these two models come together and how we utilize them 00:53:00.370 --> 00:53:04.083 in order to form our public safety power shutoff. 00:53:04.920 --> 00:53:07.015 And the last thing I'll leave you with is another acronym 00:53:07.015 --> 00:53:10.280 and I apologize for all the acronyms here, 00:53:10.280 --> 00:53:13.280 but the combination of the two models, 00:53:13.280 --> 00:53:18.160 we call our large fire probability distribution model. 00:53:18.160 --> 00:53:22.330 So LSP, and you'll see that on the next slide, I believe. 00:53:22.330 --> 00:53:23.453 So if we go there. 00:53:25.350 --> 00:53:30.350 This slide really talks about and gives you 00:53:31.240 --> 00:53:34.110 kind of the exact formula of how we would execute 00:53:34.110 --> 00:53:37.523 a public safety power, shutoff event. 00:53:38.860 --> 00:53:43.460 And one thing I need to start off on 00:53:43.460 --> 00:53:48.460 is that this is essentially our 2020 PSPS framework 00:53:48.840 --> 00:53:52.810 for the distribution system and the box that you see 00:53:52.810 --> 00:53:56.530 in blue that says additional proposed criteria, 00:53:56.530 --> 00:54:00.880 it's kind of in the center of the plot, bottom center, 00:54:00.880 --> 00:54:05.880 that is the proposed new criteria to address 00:54:06.870 --> 00:54:11.870 the proposed conditions from the Federal Court. 00:54:12.200 --> 00:54:14.830 And so that would be the new criteria 00:54:14.830 --> 00:54:16.920 where all the other criteria, 00:54:16.920 --> 00:54:20.000 essentially what we executed to in 2020. 00:54:25.380 --> 00:54:28.660 And so, yeah, let me just take you through exactly 00:54:29.500 --> 00:54:34.363 how PSPS works and how we would consider this new criteria. 00:54:35.350 --> 00:54:39.510 And so the first step of determining whether or not 00:54:39.510 --> 00:54:42.370 we're going to be considering PSPS 00:54:42.370 --> 00:54:46.290 is looking at our minimum fire potential conditions 00:54:46.290 --> 00:54:49.440 and the exact logic that goes into 00:54:49.440 --> 00:54:51.420 what the minimum fire potential conditions is, 00:54:51.420 --> 00:54:56.020 has been tabled directly below that blue box on the left. 00:54:56.020 --> 00:54:58.170 And the way this is done, 00:54:58.170 --> 00:55:01.670 is for every single four kilometer squared area 00:55:01.670 --> 00:55:05.480 across the entire PG and E network, 00:55:05.480 --> 00:55:07.643 these conditions are assessed hourly, 00:55:08.740 --> 00:55:13.090 going out a little over four days in our forecast horizon. 00:55:13.090 --> 00:55:17.140 And so we can get a sense of if there are conditions 00:55:17.140 --> 00:55:21.680 that have historically led to some of the catastrophic fires 00:55:21.680 --> 00:55:25.270 in California history present or not present. 00:55:25.270 --> 00:55:29.220 And if so, then we transition into the middle box. 00:55:29.220 --> 00:55:31.050 So for each one of those areas 00:55:31.050 --> 00:55:33.170 that have minimum fire potential conditions, 00:55:33.170 --> 00:55:36.373 we consider boxes two, three or four. 00:55:37.920 --> 00:55:42.750 And box two is our large fire probability model 00:55:42.750 --> 00:55:45.230 which I discussed on the previous slide 00:55:45.230 --> 00:55:48.470 which is again the probability of an outage 00:55:48.470 --> 00:55:52.380 based on wind speed multiplied by our fire potential index. 00:55:52.380 --> 00:55:54.983 It's the probability of large fires. 00:55:56.410 --> 00:55:58.410 And then the next box below that, 00:55:58.410 --> 00:56:03.050 is what we call our distribution black swan conditions. 00:56:03.050 --> 00:56:08.050 And those criteria are in the bottom right-hand portion 00:56:08.810 --> 00:56:12.020 of the chart there and they're really meant to capture 00:56:12.020 --> 00:56:15.440 those very low probability 00:56:15.440 --> 00:56:19.030 but potentially high consequence incidents. 00:56:19.030 --> 00:56:22.360 And it adds a very small addition 00:56:25.040 --> 00:56:28.150 to the overall scope of a PSPS. 00:56:28.150 --> 00:56:31.593 Less than a percent are identified as a black swan. 00:56:32.440 --> 00:56:36.360 The new proposed criteria to address 00:56:36.360 --> 00:56:41.360 the Federal Courts proposed condition is in the box below. 00:56:41.680 --> 00:56:45.210 And so if minimum fire potential conditions are met, 00:56:45.210 --> 00:56:46.310 then we would consider 00:56:46.310 --> 00:56:50.540 that geographic footprint of where the 70th percentile 00:56:50.540 --> 00:56:54.090 and above overstrike exposure is at, 00:56:54.090 --> 00:56:57.380 as well as the existence of priority one 00:56:57.380 --> 00:57:01.657 or priority two trees to essentially establish the scope 00:57:04.820 --> 00:57:08.283 of PSPS on our distribution system. 00:57:09.150 --> 00:57:12.530 And so this is the proposal 00:57:12.530 --> 00:57:16.610 and there's a lot of detail. 00:57:16.610 --> 00:57:20.716 I can go into every single one of these items. 00:57:20.716 --> 00:57:24.070 And I don't wanna go into that level of detail here. 00:57:24.070 --> 00:57:27.313 A lot of this can be found in our Wildfire Mitigation Plan. 00:57:28.640 --> 00:57:32.250 Another thing I wanted to kind of mention 00:57:32.250 --> 00:57:34.690 and into a little bit detail on, 00:57:34.690 --> 00:57:38.090 is, you know, I've been bringing up the concept 00:57:38.090 --> 00:57:40.970 of our historical climatology. 00:57:40.970 --> 00:57:44.130 That hour by hour historical look back 00:57:44.130 --> 00:57:47.940 that we have of that goes back 30 years. 00:57:47.940 --> 00:57:51.250 And one of the things that's very powerful 00:57:51.250 --> 00:57:53.890 about that data set is having the ability 00:57:53.890 --> 00:57:56.600 to run sensitivity analyses 00:57:57.479 --> 00:58:02.479 and understand what this additional criteria 00:58:03.230 --> 00:58:07.660 to PSPS would mean in terms of the size, 00:58:07.660 --> 00:58:11.060 the scope and the duration of PSPS events. 00:58:11.060 --> 00:58:14.150 And so what we're able to do 00:58:14.150 --> 00:58:17.910 and what my team is able to do is take this criteria 00:58:17.910 --> 00:58:21.970 and take this methodology and run it hour by hour. 00:58:21.970 --> 00:58:24.663 And we did this going back 11 years to determine 00:58:24.663 --> 00:58:29.148 how many events, if we had a time machine with this criteria 00:58:29.148 --> 00:58:30.770 what would we have executed on, 00:58:30.770 --> 00:58:33.760 how many catastrophic fires would we have captured 00:58:33.760 --> 00:58:35.340 or not captured 00:58:35.340 --> 00:58:38.870 and importantly, what does this mean for our customers? 00:58:38.870 --> 00:58:41.570 And then what can we do to help mitigate 00:58:41.570 --> 00:58:43.180 some of the impact to our customers 00:58:43.180 --> 00:58:46.610 which is coming up a little bit later today. 00:58:46.610 --> 00:58:49.170 I think Jake Zigelman is gonna be recording 00:58:49.170 --> 00:58:50.743 out for PG and E on that. 00:58:52.830 --> 00:58:56.100 And so I think the next three slides 00:58:58.690 --> 00:59:02.193 talk about some of the impacts 00:59:02.193 --> 00:59:05.420 that we've been able to determine 00:59:05.420 --> 00:59:08.190 based on that historic look back. 00:59:08.190 --> 00:59:10.248 Taking the proposed conditions, 00:59:10.248 --> 00:59:13.050 running it back through time, 00:59:13.050 --> 00:59:14.510 aggregating the results 00:59:14.510 --> 00:59:18.340 and then comparing it to what we executed on in 2020. 00:59:20.820 --> 00:59:24.600 And so what we executed to in 2020, 00:59:24.600 --> 00:59:27.960 and if we took our 2020 guidance and ran it back in the past 00:59:27.960 --> 00:59:30.703 that is what we call the baseline. 00:59:31.780 --> 00:59:34.999 And this chart that we're showing now, 00:59:34.999 --> 00:59:38.820 if you look at the baseline column, 00:59:38.820 --> 00:59:43.820 that is essentially the 2020 model run backwards 00:59:45.360 --> 00:59:48.230 over an 11 year period. 00:59:48.230 --> 00:59:49.860 And what we find when we do that 00:59:49.860 --> 00:59:54.000 is we have about three events per year on average. 00:59:54.000 --> 00:59:58.970 The average event duration from a weather perspective only 00:59:58.970 --> 01:00:00.683 is about 24 hours. 01:00:01.530 --> 01:00:03.470 The average event customer count 01:00:03.470 --> 01:00:06.200 is almost a hundred thousand 01:00:06.200 --> 01:00:10.500 and the largest event customer count is about 345,000 01:00:11.710 --> 01:00:15.930 if we take our 2020 model and run it backward in time. 01:00:15.930 --> 01:00:17.980 One important note here is that 01:00:17.980 --> 01:00:22.980 this is only considering distribution customers only. 01:00:24.660 --> 01:00:28.450 Now when we, or I guess the next column 01:00:28.450 --> 01:00:31.110 over from the baseline is 01:00:31.110 --> 01:00:34.830 with the additional consideration 01:00:34.830 --> 01:00:39.280 of vegetation overstrike to address 01:00:39.280 --> 01:00:42.790 the potential proposed conditions from the Federal Court. 01:00:42.790 --> 01:00:47.370 And when we add that criteria in, 01:00:47.370 --> 01:00:49.300 what that could potentially mean 01:00:49.300 --> 01:00:51.507 when we look at that same historical data set, 01:00:51.507 --> 01:00:55.970 the same exact weather, just slightly different criteria 01:00:55.970 --> 01:00:59.480 the average number of events goes from three to five, 01:00:59.480 --> 01:01:02.750 the event duration goes from 24 hours to 29 01:01:02.750 --> 01:01:03.800 for an average event. 01:01:04.720 --> 01:01:07.600 Which represents an 18% increase on the duration. 01:01:07.600 --> 01:01:10.513 The increase in percentage is on the far right. 01:01:11.370 --> 01:01:13.740 The average event size goes up 01:01:15.031 --> 01:01:17.090 and also the largest event goes up. 01:01:17.090 --> 01:01:22.090 The largest events of obviously is dependent on, you know 01:01:22.350 --> 01:01:24.963 the strongest weather that we would experience. 01:01:27.100 --> 01:01:28.950 One thing to call out too, 01:01:28.950 --> 01:01:33.950 is that as the events get stronger in magnitude, 01:01:34.327 --> 01:01:39.327 the percentage of increase actually goes down 01:01:39.660 --> 01:01:42.643 so that when we get to the largest event count, 01:01:43.510 --> 01:01:47.373 the size of the event only grows by about 6%. 01:01:48.410 --> 01:01:50.040 And that's because we start to get 01:01:50.040 --> 01:01:52.730 into a realm where our outage cruising wind model 01:01:52.730 --> 01:01:56.467 is capturing a lot of that geographic footprint. 01:01:56.467 --> 01:01:59.050 We're seeing high outage probabilities 01:01:59.050 --> 01:02:03.140 or black swan comes into play and other kind of criteria 01:02:03.140 --> 01:02:07.043 of our PSPS model are capturing some of those areas. 01:02:09.110 --> 01:02:10.430 Another thing I can mention 01:02:10.430 --> 01:02:13.010 is that on the event frequency side 01:02:13.900 --> 01:02:18.290 the two events that would potentially be added per year 01:02:18.290 --> 01:02:22.540 would be of the smaller to moderate variety 01:02:22.540 --> 01:02:27.540 and so we're not adding, you know, significant PSPS events 01:02:28.130 --> 01:02:30.095 although, you know, if you're a customer 01:02:30.095 --> 01:02:33.270 that's experiencing a PSPS event, 01:02:33.270 --> 01:02:37.470 we know that any event is significant 01:02:38.660 --> 01:02:41.500 but in terms of the overall size of the event, 01:02:41.500 --> 01:02:44.860 we're not adding, you know, some of the larger events 01:02:44.860 --> 01:02:48.660 it's more of the smaller more moderate type events 01:02:48.660 --> 01:02:52.040 that are ultimately being added to the scope. 01:02:52.040 --> 01:02:54.370 And I believe the next slide actually gives 01:02:54.370 --> 01:02:58.210 the year by year impact and changes. 01:02:58.210 --> 01:03:01.300 And so there's a lot of good information here 01:03:01.300 --> 01:03:02.443 I'll cover now. 01:03:04.575 --> 01:03:09.575 And this really gives, if we go back to 2010 to 2020 01:03:10.180 --> 01:03:13.920 and run that framework and actually 01:03:13.920 --> 01:03:15.890 there's a couple of frameworks that we're running here. 01:03:15.890 --> 01:03:19.260 We're running the baseline model back in the past. 01:03:19.260 --> 01:03:22.860 That is what's covered in the blue columns. 01:03:22.860 --> 01:03:27.670 So if we took our 2020 criteria without vegetation added 01:03:27.670 --> 01:03:29.260 and we ran it back 10 years, 01:03:29.260 --> 01:03:32.230 that's how many events, PSPS events 01:03:32.230 --> 01:03:33.663 we would have experienced. 01:03:35.650 --> 01:03:38.900 With the vegetation component added 01:03:40.040 --> 01:03:43.760 and that is represented by the orange bars. 01:03:43.760 --> 01:03:47.650 So you can look at each year and see how many events 01:03:47.650 --> 01:03:52.296 were added or not added such like 2014 and 2020. 01:03:52.296 --> 01:03:55.933 And then the gray bars are are actually what we executed to. 01:03:57.130 --> 01:03:59.760 And one important note there 01:03:59.760 --> 01:04:03.020 because you may be saying, okay, in 2019 01:04:03.020 --> 01:04:06.120 that doesn't make sense why you executed seven events 01:04:06.120 --> 01:04:10.460 but your 2020 criteria only shows four. 01:04:10.460 --> 01:04:13.160 And the reason being is that every single year 01:04:13.160 --> 01:04:14.980 since we've had PSPS 01:04:14.980 --> 01:04:17.160 we're on a continuous improvement journey 01:04:17.160 --> 01:04:22.160 and our criteria is improving each year. 01:04:22.240 --> 01:04:26.470 And we're in that continuous improvement phase right now. 01:04:26.470 --> 01:04:30.600 So in the off season, when we're not in, you know 01:04:30.600 --> 01:04:34.030 extreme fire risk, my team works on all 01:04:34.030 --> 01:04:36.230 the identified improvements that we can make 01:04:36.230 --> 01:04:39.610 to our fire potential index now decreasing wind model 01:04:39.610 --> 01:04:43.690 such that we can operationalize those models, you know 01:04:43.690 --> 01:04:45.230 by the upcoming fire season. 01:04:45.230 --> 01:04:49.290 And so every year we've kind of had that 01:04:51.370 --> 01:04:54.660 kind of continuous improvement cadence, if you will, 01:04:54.660 --> 01:04:55.930 and this year is no different. 01:04:55.930 --> 01:05:00.140 We're working on both of those core concepts 01:05:00.140 --> 01:05:01.840 of the model as all some other things. 01:05:01.840 --> 01:05:04.920 And I'm very excited about, you know, 01:05:04.920 --> 01:05:08.250 the new developments that we're making in some of the space. 01:05:08.250 --> 01:05:10.750 And that's a totally different conversation 01:05:10.750 --> 01:05:13.410 that I hope have soon. 01:05:13.410 --> 01:05:18.410 But that explains why our 2019 model 01:05:20.110 --> 01:05:21.790 and version of PSPS 01:05:21.790 --> 01:05:26.160 over your executing to that has shown seven events 01:05:26.160 --> 01:05:29.900 and why if we ran our 2020 model now for 2019 01:05:29.900 --> 01:05:32.470 some of the events that we actually executed on 01:05:32.470 --> 01:05:34.950 would not be PSPS events now. 01:05:34.950 --> 01:05:39.250 I'll give you an example, like our June 8th PSPS event 01:05:39.250 --> 01:05:42.100 where we had pretty significant to live fuel moistures 01:05:42.100 --> 01:05:46.750 so present in our territory is one example of a 2019 event. 01:05:46.750 --> 01:05:49.560 And it's really those marginal very small events 01:05:49.560 --> 01:05:51.660 that ended up not being events. 01:05:51.660 --> 01:05:54.606 But you know a couple other things 01:05:54.606 --> 01:05:57.400 that kind of stand out to me is that 01:05:58.360 --> 01:06:02.060 there's a lot of year to year variability 01:06:02.060 --> 01:06:06.270 in the number of PSPS events that one sees 01:06:06.270 --> 01:06:10.230 when you look at the weather that you get, right? 01:06:10.230 --> 01:06:14.980 And, you know, I'll maybe pull this adage 01:06:14.980 --> 01:06:16.750 out of the hat but, you know, climate 01:06:16.750 --> 01:06:19.150 is what you expect every year. 01:06:19.150 --> 01:06:22.970 So the average of the number of events, 01:06:22.970 --> 01:06:26.180 we get 4.8 with the new vegetation criteria. 01:06:26.180 --> 01:06:28.690 So that's representation of the climate. 01:06:28.690 --> 01:06:30.300 So that's what we expect 01:06:30.300 --> 01:06:33.240 but the weather is what we get, right? 01:06:33.240 --> 01:06:35.930 And so this year's weather, 01:06:35.930 --> 01:06:38.720 we really don't have a sense of what's going to happen. 01:06:38.720 --> 01:06:40.900 We have a sense that fire danger is trending worse. 01:06:40.900 --> 01:06:43.440 But one thing that we see going back 01:06:43.440 --> 01:06:46.920 to the significant drought years, 2012, through 2016 01:06:46.920 --> 01:06:48.800 if you look at that five-year timeframe 01:06:48.800 --> 01:06:50.820 when we were in considerable drought 01:06:50.820 --> 01:06:54.610 the weather was kind of in a more quiescent, quiet pattern 01:06:54.610 --> 01:06:56.040 and we didn't really see a lot 01:06:56.040 --> 01:06:58.700 of off shore Diablo wind events occurring 01:06:58.700 --> 01:07:01.983 and so the number of PSPS events was below average. 01:07:02.965 --> 01:07:05.880 And so anyway this is kind of like winter storms, right? 01:07:05.880 --> 01:07:08.630 The number of the amount of precipitation 01:07:08.630 --> 01:07:11.520 each year's highly variable year. 01:07:11.520 --> 01:07:14.380 Right now we're in a bus year, 01:07:14.380 --> 01:07:15.213 a couple of years ago 01:07:15.213 --> 01:07:17.720 we were insignificant balloon times, if you will, 01:07:17.720 --> 01:07:19.873 from a water perspective. 01:07:21.260 --> 01:07:23.850 and that's what we should expect moving forward for PSPS. 01:07:23.850 --> 01:07:26.760 Some years we're gonna have an abnormally 01:07:26.760 --> 01:07:30.990 or abnormal number of offshore Diablo wind events 01:07:30.990 --> 01:07:35.990 which will lead to more PSPS some years, hopefully sooner, 01:07:36.770 --> 01:07:39.010 we'll have less offshore wind events 01:07:39.010 --> 01:07:41.080 and quieter years. 01:07:41.080 --> 01:07:44.610 So that's just a kind of a lesson of what to expect. 01:07:44.610 --> 01:07:47.853 It's very tough when dealing with operational weather. 01:07:49.460 --> 01:07:53.100 So to tease out a couple of other things here, 01:07:53.100 --> 01:07:58.100 2014 and 2020 these are years where the additional criteria 01:08:00.350 --> 01:08:02.080 would not have increased. 01:08:02.080 --> 01:08:05.123 The number of times PSPS is calm. 01:08:06.970 --> 01:08:10.320 However, this is only looking at the frequency 01:08:10.320 --> 01:08:12.250 of PSPS events. 01:08:12.250 --> 01:08:15.980 It's also important to consider the duration 01:08:15.980 --> 01:08:17.180 as well as the size. 01:08:17.180 --> 01:08:18.670 How many customers are impacted. 01:08:18.670 --> 01:08:22.930 And from those angles, from those dimensions, 01:08:22.930 --> 01:08:26.060 you know PSPS is getting larger. 01:08:26.060 --> 01:08:29.620 So I just wanted to also say that it's important to look 01:08:29.620 --> 01:08:32.640 at PSPS, not just from a frequency standpoint, 01:08:32.640 --> 01:08:35.450 but also from those other two dimensions as well. 01:08:35.450 --> 01:08:37.730 And we're looking at those very closely 01:08:37.730 --> 01:08:42.203 when considering any new criteria to execute on. 01:08:43.360 --> 01:08:45.240 And so if we go to the next slide, 01:08:45.240 --> 01:08:47.190 I believe this is my final slide 01:08:47.190 --> 01:08:50.500 and then I'll stop for questions. 01:08:50.500 --> 01:08:54.390 But we're also trying to understand, you know 01:08:54.390 --> 01:08:59.390 each County specific impact from these new criteria. 01:09:00.930 --> 01:09:04.480 And what we're finding is that some counties 01:09:04.480 --> 01:09:08.350 are going to be impacted more than other counties 01:09:08.350 --> 01:09:10.360 and the counties that are gonna be impacted more 01:09:10.360 --> 01:09:12.730 by the implementation of this new criteria 01:09:12.730 --> 01:09:16.950 are primarily those counties that one, 01:09:16.950 --> 01:09:20.740 have, you know, a high amount of overstrike exposure 01:09:20.740 --> 01:09:21.600 next to our lines. 01:09:21.600 --> 01:09:24.370 These are heavily forested areas. 01:09:24.370 --> 01:09:29.370 And two, they experience offshore dry wind events 01:09:29.460 --> 01:09:30.940 more than others. 01:09:30.940 --> 01:09:32.680 And generally these are locations 01:09:32.680 --> 01:09:34.770 that are in the Northern Sierra. 01:09:34.770 --> 01:09:37.510 The kind of Shasta-Trinity area 01:09:37.510 --> 01:09:39.780 where we get those North winds 01:09:39.780 --> 01:09:43.620 as well as the North Bay in Santa Cruz mountains. 01:09:43.620 --> 01:09:47.450 Primarily the kind of geographic footprint North 01:09:47.450 --> 01:09:52.443 of generally a moderate to about a kind of Highway 88 line. 01:09:56.140 --> 01:09:59.320 Areas across farther down in the South, 01:09:59.320 --> 01:10:02.390 they don't experience as many offshore wind events 01:10:02.390 --> 01:10:04.150 on average, historically, right? 01:10:04.150 --> 01:10:06.935 This is all based on looking at past weather. 01:10:06.935 --> 01:10:11.410 And so those counties that are more in Northern California 01:10:11.410 --> 01:10:14.647 are going to be impacted more with this criteria. 01:10:14.647 --> 01:10:18.440 And this is an example of Butte County's 01:10:19.930 --> 01:10:23.710 kind of history looking at the 2020 model. 01:10:23.710 --> 01:10:25.990 The 2020 model's plus 70 percentile 01:10:25.990 --> 01:10:29.410 and above overstrike exposure areas 01:10:30.630 --> 01:10:35.523 as well as what was executed on in 2019 and 2020. 01:10:36.370 --> 01:10:40.300 And it's important to note that we've created these 01:10:40.300 --> 01:10:42.440 for every single County. 01:10:42.440 --> 01:10:44.770 And I think this is gonna be covered 01:10:44.770 --> 01:10:48.300 in the kind of customer communication portion 01:10:48.300 --> 01:10:52.910 of today's discussion but we are in the process 01:10:52.910 --> 01:10:57.100 of communicating these potential impacts to counties 01:10:57.100 --> 01:10:59.983 should these proposed conditions be implemented. 01:11:01.930 --> 01:11:06.410 So I believe that's the totality of my presentation 01:11:06.410 --> 01:11:09.363 and I'll be happy to stop and take your questions. 01:11:17.610 --> 01:11:20.120 Yes Scott, this is Jeff Fuentes with Cal FIRE. 01:11:20.120 --> 01:11:22.380 Thank you for the presentation. 01:11:22.380 --> 01:11:23.640 I did have a question 01:11:24.780 --> 01:11:27.440 and it was kind of a two-part question, 01:11:27.440 --> 01:11:29.690 kind of going back to the decision-making slide 01:11:29.690 --> 01:11:32.720 and looking at the different thresholds that were there. 01:11:32.720 --> 01:11:35.430 And it sounded like those were the same thresholds 01:11:35.430 --> 01:11:40.430 for 2020 with the exception of that new 01:11:40.690 --> 01:11:42.130 potential overstrike data. 01:11:42.130 --> 01:11:43.200 Is that correct? 01:11:43.200 --> 01:11:44.600 And then kind of the second part 01:11:44.600 --> 01:11:47.090 I'm wondering how you guys are accounting 01:11:47.090 --> 01:11:48.840 for hardened distribution circuits. 01:11:48.840 --> 01:11:52.750 So for example, you know, circuits with covered conductor 01:11:52.750 --> 01:11:55.890 you know, is there a different wind threshold for those? 01:11:55.890 --> 01:11:58.940 Are they just completely removed from scope 01:11:58.940 --> 01:12:01.330 in those areas kind of looking 01:12:01.330 --> 01:12:02.880 at that decision-making slides. 01:12:04.430 --> 01:12:05.263 Great. Yeah. 01:12:05.263 --> 01:12:06.230 Yeah. Thank you, Jeff. 01:12:07.670 --> 01:12:09.710 Yeah. So going back to the decision-making slide 01:12:09.710 --> 01:12:11.550 if we can go there, I think it's 01:12:12.500 --> 01:12:16.340 if you advance one more please on the slide 01:12:17.630 --> 01:12:19.550 and you're talking about this one, Jeff. 01:12:19.550 --> 01:12:23.380 Yeah, there has been one slight change 01:12:23.380 --> 01:12:26.410 from what we actually executed on in 2020. 01:12:26.410 --> 01:12:29.750 And I believe our minimum fire potential conditions 01:12:29.750 --> 01:12:33.980 have slightly different dead fuel moisture 01:12:34.960 --> 01:12:38.630 kind of thresholds and so the dead fuel moisture thresholds 01:12:38.630 --> 01:12:43.630 were actually adjusted for use in 2020 and 2021. 01:12:44.000 --> 01:12:46.580 And that's under consideration. 01:12:46.580 --> 01:12:49.440 Essentially everything with a double asterisk 01:12:49.440 --> 01:12:53.500 is under consideration based on the update cadence 01:12:53.500 --> 01:12:54.333 that I mentioned. 01:12:54.333 --> 01:12:58.910 So essentially we're and my team are delving 01:12:58.910 --> 01:13:01.804 through all the data from 2020. 01:13:01.804 --> 01:13:06.804 All the fires that happened, all the wind patterns 01:13:06.930 --> 01:13:09.850 all the dead fuel moistures to substantiate 01:13:09.850 --> 01:13:11.978 any adjustments to the criteria. 01:13:11.978 --> 01:13:16.110 We don't expect there to be any significant changes 01:13:16.110 --> 01:13:17.740 but there might be some. 01:13:17.740 --> 01:13:19.170 For example we're closely looking 01:13:19.170 --> 01:13:21.860 at the dead fuel moisture values to see 01:13:21.860 --> 01:13:24.140 if they can be reduced in some areas 01:13:24.140 --> 01:13:26.150 or the relative humidity to be reduced. 01:13:26.150 --> 01:13:30.260 And we have essentially for every single fire 01:13:31.220 --> 01:13:32.910 and we have a really good data set now 01:13:32.910 --> 01:13:36.023 that shows the day by day progression of each fire. 01:13:36.880 --> 01:13:38.900 We can look at the meteorological 01:13:38.900 --> 01:13:40.420 and fuel conditions related to that. 01:13:40.420 --> 01:13:44.080 So that'll support any changes that we would need to make 01:13:44.080 --> 01:13:46.620 to the minimum fire potential conditions, if you will. 01:13:46.620 --> 01:13:51.620 But aside from that small adjustment, 01:13:51.880 --> 01:13:56.880 essentially everything else was the same in 2020 01:13:57.140 --> 01:14:00.150 aside from box four 01:14:00.150 --> 01:14:02.910 that's in the additional proposed criteria. 01:14:02.910 --> 01:14:04.020 And I'll pause there to see 01:14:04.020 --> 01:14:06.560 if I answered your first question 01:14:06.560 --> 01:14:08.610 before moving on to your second question. 01:14:09.790 --> 01:14:11.460 Yes. Thank you. 01:14:11.460 --> 01:14:12.293 Great. 01:14:12.293 --> 01:14:13.500 Yeah. And your second question 01:14:13.500 --> 01:14:16.540 was related to a system hardening. 01:14:16.540 --> 01:14:19.810 And so a system hardening to date 01:14:19.810 --> 01:14:22.950 has been conducted mostly on segments. 01:14:22.950 --> 01:14:24.730 So we've been focused on 01:14:24.730 --> 01:14:29.360 where we have the highest overall wildfire risk 01:14:29.360 --> 01:14:34.220 and we've been performing hardening in those segments. 01:14:34.220 --> 01:14:38.760 And, you know, not necessarily from this, 01:14:38.760 --> 01:14:40.260 all the way from the substation 01:14:40.260 --> 01:14:43.620 out to the end of the line, if you will. 01:14:43.620 --> 01:14:48.620 And if we wanted to kind of mitigate a line for PSPS, 01:14:50.140 --> 01:14:53.250 essentially that entire line would have to have 01:14:53.250 --> 01:14:57.303 a very low risk of causing a ignition. 01:15:01.767 --> 01:15:05.710 And actually in to add some more context 01:15:05.710 --> 01:15:07.470 there's two lines that we identified 01:15:07.470 --> 01:15:11.760 that there are potential pathways 01:15:11.760 --> 01:15:15.610 and methodologies to maybe adjust our criteria 01:15:15.610 --> 01:15:16.960 such that we can take into account, 01:15:16.960 --> 01:15:18.969 yes, we've done system hardening here, 01:15:18.969 --> 01:15:23.280 how can we adjust our thresholds to account for, you know 01:15:23.280 --> 01:15:25.010 the system hardening that we've done? 01:15:25.010 --> 01:15:27.660 And so those discussions are actively taking place. 01:15:27.660 --> 01:15:30.540 I actually have a meeting at 4:00p.m internally 01:15:30.540 --> 01:15:32.280 to discuss that exact concept. 01:15:32.280 --> 01:15:36.070 So we don't have that methodology worked out 01:15:36.070 --> 01:15:38.140 but those discussions are actively happening. 01:15:38.140 --> 01:15:41.610 And one thing that, that we want to do similar 01:15:41.610 --> 01:15:43.200 to other utilities that we've looked at, 01:15:43.200 --> 01:15:48.200 is collect pre versus post event system hardening data 01:15:49.950 --> 01:15:51.698 to substantiate any adjustments 01:15:51.698 --> 01:15:53.903 that we made to our criteria. 01:15:55.390 --> 01:15:57.240 And it's important that, you know, we collect 01:15:57.240 --> 01:16:00.880 that data to validate performance during wind events 01:16:00.880 --> 01:16:03.050 not just during blue sky events. 01:16:03.050 --> 01:16:05.530 So hopefully I answered your question, 01:16:05.530 --> 01:16:08.423 happy to take another run at it the possible. 01:16:09.690 --> 01:16:11.450 No, thank you, Scott. 01:16:16.870 --> 01:16:19.520 Commissioners, do you have other questions? 01:16:21.550 --> 01:16:23.240 Yes. Thank you. 01:16:23.240 --> 01:16:25.465 So if you could go back to the slide 01:16:25.465 --> 01:16:28.183 that shows the expanded duration. 01:16:32.780 --> 01:16:36.700 Are you going to give us some regional breakout of this? 01:16:36.700 --> 01:16:41.540 I know your example of view was a frequency example 01:16:41.540 --> 01:16:46.380 and I think based on what Sumeet said earlier, 01:16:46.380 --> 01:16:50.340 the potential duration is potentially 01:16:50.340 --> 01:16:52.479 an even greater concern. 01:16:52.479 --> 01:16:53.583 Is that correct? 01:16:55.980 --> 01:17:00.420 Sorry, I didn't catch your last, last sentence. 01:17:00.420 --> 01:17:02.463 Can you repeat that last portion? 01:17:04.860 --> 01:17:08.720 I think your slides while helpful in highlighting 01:17:08.720 --> 01:17:13.720 the potential increase in frequency dating back to applying 01:17:14.100 --> 01:17:17.700 those in previous years that we'll likely see 01:17:17.700 --> 01:17:19.850 a trend of frequency. 01:17:19.850 --> 01:17:23.870 However this light and the factoid 01:17:23.870 --> 01:17:28.870 that Sumeet shared with us earlier on the 5.3 million trees 01:17:31.340 --> 01:17:34.760 leads me to think that the bigger concern 01:17:34.760 --> 01:17:39.760 is actually the scope and duration of these events. 01:17:41.760 --> 01:17:44.110 Are you going to give us more detail 01:17:44.110 --> 01:17:48.880 on the geographical scope that will be impacted 01:17:49.900 --> 01:17:52.333 by adding this additional criteria? 01:17:55.200 --> 01:17:56.420 Yeah, yeah. 01:17:56.420 --> 01:17:57.640 I believe we can. 01:17:57.640 --> 01:18:00.880 And I think, yeah looking at all three dimensions, again, 01:18:00.880 --> 01:18:03.340 is very important when considering PSPS, 01:18:03.340 --> 01:18:04.440 not just the frequency. 01:18:04.440 --> 01:18:07.496 So I think you're thinking about it the right way. 01:18:07.496 --> 01:18:09.584 And for each one of these events, 01:18:09.584 --> 01:18:11.540 it starts to get very dynamic 01:18:11.540 --> 01:18:14.020 because every single circuit, every single grid cell 01:18:14.020 --> 01:18:16.000 is gonna experience the event differently. 01:18:16.000 --> 01:18:18.950 And just to give you maybe a click below the surface 01:18:18.950 --> 01:18:23.023 of how the event was, the ration was calculated, 01:18:24.340 --> 01:18:28.970 that's looking at it from a overall view of a PSPS event. 01:18:28.970 --> 01:18:32.980 So when did the event actually start for the first circuit 01:18:32.980 --> 01:18:35.960 and the when would it end for the last circuit 01:18:35.960 --> 01:18:39.090 to come out of the weather risk period, if you will. 01:18:39.090 --> 01:18:41.620 So we're looking at it from that perspective. 01:18:41.620 --> 01:18:43.600 And there's other ways to look at it 01:18:45.200 --> 01:18:47.850 whether you do it by County by County specific. 01:18:47.850 --> 01:18:51.370 And so there's almost an infinite number of ways 01:18:51.370 --> 01:18:53.610 to slice and dice the historic data 01:18:53.610 --> 01:18:55.842 in the way that we've done. 01:18:55.842 --> 01:18:58.850 But I believe if some of that analysis 01:18:58.850 --> 01:19:03.850 is, you know, we can essentially generate that if needed. 01:19:05.740 --> 01:19:08.870 Can you go to the slide that shows the larger event 01:19:08.870 --> 01:19:10.663 versus smaller event? 01:19:15.622 --> 01:19:18.539 Maybe that was larger event, sorry. 01:19:22.280 --> 01:19:24.433 Can you go back to that last slide 01:19:27.970 --> 01:19:29.563 where it has the table? 01:19:30.910 --> 01:19:32.640 The one before, yeah? 01:19:32.640 --> 01:19:33.473 Yeah. 01:19:33.473 --> 01:19:36.610 Okay. So here you're showing that obviously compared 01:19:36.610 --> 01:19:39.060 to a large event, it would be the same 01:19:39.060 --> 01:19:42.890 because we're capturing the large scope 01:19:42.890 --> 01:19:44.110 and average event. 01:19:44.110 --> 01:19:47.770 This is maybe where I'm most interested in understanding 01:19:47.770 --> 01:19:50.120 the impact of these average events 01:19:50.120 --> 01:19:52.880 because you're saying on average, 01:19:52.880 --> 01:19:55.170 the scope is gonna get bigger. 01:19:55.170 --> 01:19:56.930 And based on what you said before, 01:19:56.930 --> 01:19:59.080 it's gonna get bigger primarily 01:19:59.080 --> 01:20:03.970 in certain counties in the state. 01:20:03.970 --> 01:20:08.250 And so you showed a frequency for Butte. 01:20:08.250 --> 01:20:10.365 Can you show kind of how many customers 01:20:10.365 --> 01:20:12.607 you're talking about there? 01:20:12.607 --> 01:20:14.523 And you can follow up on that. 01:20:15.750 --> 01:20:16.870 Sure. Yeah. 01:20:16.870 --> 01:20:19.240 There's a couple of important caveats here 01:20:19.240 --> 01:20:20.993 when we're looking at the average. 01:20:22.230 --> 01:20:26.870 So if we looked at the average of all events 01:20:26.870 --> 01:20:28.423 with the proposed criteria, 01:20:29.510 --> 01:20:32.020 the average actually goes down 01:20:32.020 --> 01:20:34.040 in terms of the number of customers 01:20:34.040 --> 01:20:35.640 that will experienced a PSPS event 01:20:35.640 --> 01:20:40.000 because we're adding smaller events. 01:20:40.000 --> 01:20:43.640 And so in order to represent an average, 01:20:43.640 --> 01:20:45.920 we wanted to put it on terms that the baseline. 01:20:45.920 --> 01:20:47.680 So we only took the baseline, 01:20:47.680 --> 01:20:50.160 the average of the events that are in the baseline, 01:20:50.160 --> 01:20:50.993 if that makes sense, 01:20:50.993 --> 01:20:53.810 to compare the average apples to apples. 01:20:53.810 --> 01:20:55.970 So that hopefully that makes sense 01:20:55.970 --> 01:20:57.950 and gives you some context because we didn't feel 01:20:57.950 --> 01:21:00.840 like it was representative to show the average 01:21:00.840 --> 01:21:02.450 of all the events 'cause they've actually showed 01:21:02.450 --> 01:21:05.580 the average going down which doesn't really make sense. 01:21:05.580 --> 01:21:09.090 So if that provides some context there. 01:21:09.090 --> 01:21:13.160 But in terms of, yeah, the customer impacts per County 01:21:13.160 --> 01:21:17.970 don't have that off the top of my head or in my back pocket 01:21:17.970 --> 01:21:21.196 right now but that's something that can be generated 01:21:21.196 --> 01:21:23.197 in post analysis if needed.. 01:21:24.437 --> 01:21:26.140 [Smith[ Thank you Scott and Commissioner Guzman. 01:21:26.140 --> 01:21:26.973 This is Smith. 01:21:26.973 --> 01:21:30.060 We'll take that as a follow-up for your reference. 01:21:30.060 --> 01:21:33.150 It's gonna be very difficult to see the resolution 01:21:33.150 --> 01:21:34.190 if you go to the last slide 01:21:34.190 --> 01:21:37.030 but it's in the materials that were sent out. 01:21:37.030 --> 01:21:38.990 If you actually look at that last slide 01:21:38.990 --> 01:21:40.960 that provides the frequency piece, 01:21:40.960 --> 01:21:44.940 not just for Butte, but all of the other 47 counties 01:21:44.940 --> 01:21:46.740 within a high fire threat districts. 01:21:46.740 --> 01:21:49.330 It's the last slide in the appendix. 01:21:49.330 --> 01:21:50.760 So that's been distributed 01:21:50.760 --> 01:21:53.880 and what we can add to your request, Commissioner Guzman, 01:21:53.880 --> 01:21:57.280 is if you go back to that same table, I'm sorry. 01:21:57.280 --> 01:21:58.440 Of course helping with the slides. 01:21:58.440 --> 01:22:01.520 Yep. We can provide you with that context by County 01:22:01.520 --> 01:22:04.480 not just the frequency, but also add the duration 01:22:04.480 --> 01:22:05.857 and average event customer count increase 01:22:05.857 --> 01:22:07.600 if that's the question you were asking 01:22:07.600 --> 01:22:10.050 so we can take them to the follow-up, no problem. 01:22:11.690 --> 01:22:12.523 Thank you. 01:22:12.523 --> 01:22:14.930 Yeah. And one thing I wanted to call out 01:22:14.930 --> 01:22:17.283 and apologies for not doing this is that, 01:22:18.860 --> 01:22:22.800 we don't expect based on this historical analysis 01:22:22.800 --> 01:22:27.000 to return to 2019 levels of PSPS. 01:22:27.000 --> 01:22:31.510 We don't expect to have the same customer impact 01:22:31.510 --> 01:22:33.950 that was experienced in 2019. 01:22:33.950 --> 01:22:36.493 So just wanted to call that out as well. 01:22:38.440 --> 01:22:41.430 I have a question that sort of follows up 01:22:41.430 --> 01:22:43.978 on Commissioner Guzman Aceves 01:22:43.978 --> 01:22:47.220 and that is several, Butte being among them, 01:22:47.220 --> 01:22:51.493 but also in the North Bay counties as well. 01:22:52.380 --> 01:22:56.110 It's not only the scope and the duration 01:22:56.110 --> 01:22:57.133 but it's back to back. 01:22:57.133 --> 01:22:58.480 I mean, there's some folks 01:22:58.480 --> 01:23:00.853 that have had back to back PSPS. 01:23:02.030 --> 01:23:06.750 By the time you guys have finished the reenergizing 01:23:06.750 --> 01:23:08.970 we're already in the second PSPS. 01:23:08.970 --> 01:23:13.970 So when you look at the duration, hours they're turned off, 01:23:14.170 --> 01:23:18.130 some folks have been dead, you know, not, not 24 01:23:18.130 --> 01:23:21.680 which the average, I forget here, 36, whatever, 01:23:21.680 --> 01:23:23.860 it's like seven, eight days 01:23:23.860 --> 01:23:26.330 because it's not just the duration of the PS 01:23:26.330 --> 01:23:30.010 it's before you guys do your patrol and then go back into... 01:23:30.010 --> 01:23:33.420 So it would be helpful in this information 01:23:33.420 --> 01:23:34.690 maybe if you can do, 01:23:34.690 --> 01:23:36.330 and I don't know if it's possible, 01:23:36.330 --> 01:23:38.270 but showing those counties 01:23:38.270 --> 01:23:40.810 where in terms of turn on and turning off 01:23:40.810 --> 01:23:43.283 the electricity and turning it back on, 01:23:46.684 --> 01:23:50.740 how many of them had back to back over the last few years 01:23:50.740 --> 01:23:55.740 especially 19 and 20 and PSPS's 01:23:55.810 --> 01:24:00.810 and would the Federal Courts proposed new criteria 01:24:04.220 --> 01:24:07.310 escalate that I mean, given your modeling? 01:24:07.310 --> 01:24:08.470 That might be an impossible... 01:24:08.470 --> 01:24:10.440 The second might be an impossible question. 01:24:10.440 --> 01:24:11.743 I totally understand that. 01:24:14.860 --> 01:24:16.637 Yeah, I think with... 01:24:16.637 --> 01:24:17.930 Oh, am I on mute? 01:24:17.930 --> 01:24:18.763 No, I'm good. 01:24:19.700 --> 01:24:21.240 No, thank you for the question 01:24:21.240 --> 01:24:23.550 and I think that's another important dimension 01:24:23.550 --> 01:24:25.220 to look at as well. 01:24:25.220 --> 01:24:28.380 And, you know, given the two months 01:24:28.380 --> 01:24:31.730 that we've had to produce this analysis, you know, obviously 01:24:31.730 --> 01:24:36.412 we haven't been able to turn over every stone here. 01:24:36.412 --> 01:24:39.480 You know, there's one thing that, and I lived... 01:24:39.480 --> 01:24:42.090 Well, I think we all lived through the 2019 events 01:24:43.260 --> 01:24:45.800 but you know, in 2019 01:24:45.800 --> 01:24:50.800 I think there was two or three kind of triple hitters 01:24:50.810 --> 01:24:53.080 that we got where we had, you know 01:24:53.080 --> 01:24:56.200 an event followed by an event, followed by an event. 01:24:56.200 --> 01:25:00.290 And what's very concerning to me about those, 01:25:00.290 --> 01:25:05.290 and, you know, Jeff Fuentes from Cal FIRE, you know, 01:25:05.760 --> 01:25:08.680 can chime in here but after we get the first event, 01:25:08.680 --> 01:25:11.810 you know, it's dry and things start to dry out 01:25:11.810 --> 01:25:14.530 and fuels just get drier and drier with every event. 01:25:14.530 --> 01:25:16.830 So even by the time we get the third event 01:25:18.860 --> 01:25:22.170 some pretty scary fuel situations can develop, you know, 01:25:22.170 --> 01:25:23.420 if we're in October and November, 01:25:23.420 --> 01:25:25.160 it hasn't rained in six months. 01:25:25.160 --> 01:25:28.050 And so those in my mind 01:25:28.050 --> 01:25:30.687 are some of the most dangerous events that we have. 01:25:30.687 --> 01:25:32.760 But we're looking at it. 01:25:32.760 --> 01:25:37.760 But I do think we can look at it in that lens. 01:25:40.410 --> 01:25:43.260 One thing we haven't considered in this analysis 01:25:43.260 --> 01:25:47.250 that you've seen today is the restoration time 01:25:47.250 --> 01:25:48.207 to restore customers. 01:25:48.207 --> 01:25:49.790 And we can make some assumptions 01:25:49.790 --> 01:25:52.810 in the past about you know, 12 daylight hours 01:25:52.810 --> 01:25:54.730 or something like that and then look at okay, 01:25:54.730 --> 01:25:58.583 if we add 12 daylight hours on the last kind of time 01:26:00.380 --> 01:26:01.650 where the weather subsides 01:26:01.650 --> 01:26:04.043 where we would issue traditional clears, 01:26:04.960 --> 01:26:06.994 what does that look like for events that go back to back? 01:26:06.994 --> 01:26:11.994 And look at the maximum duration, if you will, 01:26:12.190 --> 01:26:14.179 that might be another dimension to analyze as well. 01:26:14.179 --> 01:26:16.050 But yeah. 01:26:16.050 --> 01:26:20.110 Easy to read because that really shows the impact 01:26:20.110 --> 01:26:24.670 particularly for our folks, your customers. 01:26:24.670 --> 01:26:27.480 The rate payers who are considered 01:26:27.480 --> 01:26:31.810 part of the medical baseline and need backup battery 01:26:31.810 --> 01:26:34.490 and when they experienced a PSPS 01:26:34.490 --> 01:26:39.490 that lasts days in terms of them not having electricity, 01:26:44.310 --> 01:26:46.477 it's just a huge you know, the impacts are huge. 01:26:46.477 --> 01:26:51.477 Impacts are huge to obviously food spoilage, et cetera. 01:26:55.410 --> 01:26:58.910 So I think that's a piece of this story 01:26:58.910 --> 01:27:00.680 that we need to be able to tell. 01:27:00.680 --> 01:27:03.300 One of my concerns is not only the safety 01:27:06.368 --> 01:27:09.170 of the public, of why you call a PSPS, 01:27:10.090 --> 01:27:13.470 of course it's the last resort 01:27:13.470 --> 01:27:15.260 but it's also the safety of people 01:27:15.260 --> 01:27:18.150 who are experiencing a PSPS. 01:27:18.150 --> 01:27:21.130 And it's a huge concern. 01:27:21.130 --> 01:27:24.090 Both sides of that equation, if you will. 01:27:24.090 --> 01:27:25.540 So, okay, I'll stop there. 01:27:25.540 --> 01:27:28.610 I know we're probably running a little bit behind now. 01:27:28.610 --> 01:27:30.117 Scott, this is Commissioner Rechtschffen 01:27:30.117 --> 01:27:31.683 and I have a question for you. 01:27:32.550 --> 01:27:37.327 You mentioned how much variability there is about weather 01:27:39.240 --> 01:27:41.374 and I would say climate. 01:27:41.374 --> 01:27:45.340 2020 is a good example of the fire season 01:27:45.340 --> 01:27:47.160 defied all expectations. 01:27:47.160 --> 01:27:49.280 It's the largest ever. 01:27:49.280 --> 01:27:50.930 You noted we're in a drought 01:27:50.930 --> 01:27:53.367 or in the prior drought weather conditions 01:27:53.367 --> 01:27:58.343 can been conspire to result in a lot of PSPS as they could. 01:27:59.590 --> 01:28:03.700 My question is, can you share with us a sensitivity analysis 01:28:03.700 --> 01:28:08.050 that you've run that show what happens in some worst case 01:28:08.050 --> 01:28:09.800 or less best worst? 01:28:09.800 --> 01:28:11.810 I don't know if worse is the word 01:28:11.810 --> 01:28:16.110 but in more troubling circumstances of the scope of PSPS 01:28:16.110 --> 01:28:18.857 is under this new regime in 2021. 01:28:18.857 --> 01:28:21.200 'Cause I'm a little worried that we're getting, 01:28:21.200 --> 01:28:24.027 I don't know if you've done that already. 01:28:24.027 --> 01:28:26.580 If it's in the dependencies this is a range of PSPS 01:28:26.580 --> 01:28:30.350 but I'm very worried about a worst set of conditions 01:28:30.350 --> 01:28:31.590 will determine what the scope 01:28:31.590 --> 01:28:34.223 and extent would be of the PSPSs. 01:28:36.540 --> 01:28:38.780 Yeah, I think we could absolutely take that 01:28:38.780 --> 01:28:42.520 as a follow-up and part of what we do is run 01:28:42.520 --> 01:28:44.580 a lot of sensitivity studies 01:28:44.580 --> 01:28:49.580 to set our PSPS framework every year. 01:28:50.380 --> 01:28:53.710 And we've done this for the vegetation criteria. 01:28:53.710 --> 01:28:56.660 We looked at various percentiles 01:28:56.660 --> 01:29:00.190 of the vegetation overstrike percentile 01:29:00.190 --> 01:29:02.625 and I believe it's one of the slides in the appendix 01:29:02.625 --> 01:29:04.850 and we don't need to go there now. 01:29:04.850 --> 01:29:08.480 I think if folks wanna look at that information, they can 01:29:08.480 --> 01:29:10.330 but essentially that shows that yeah 01:29:10.330 --> 01:29:14.237 if we expand the geographic footprint of the percentile 01:29:14.237 --> 01:29:16.150 and above that we're considering 01:29:16.150 --> 01:29:20.100 the amount of risks that we're capturing increases 01:29:20.100 --> 01:29:22.430 but there's a disproportionate impact 01:29:22.430 --> 01:29:24.973 to a customer's from a PSPS standpoint. 01:29:25.990 --> 01:29:28.570 And then as far as your comments about the drought, 01:29:28.570 --> 01:29:33.570 yeah, it's very concerning to us 01:29:34.040 --> 01:29:36.810 and we're evaluating that closely. 01:29:36.810 --> 01:29:41.810 However, we do need a Diablo wind event 01:29:42.520 --> 01:29:44.880 or some sort of offshore wind pattern 01:29:44.880 --> 01:29:49.810 or dry winds coupled with dry conditions, 01:29:49.810 --> 01:29:52.610 basically dry relative humidity, dry fuels on the ground 01:29:53.550 --> 01:29:55.870 in order to consider PSPS. 01:29:55.870 --> 01:29:59.050 We're not going to be executing PSPS 01:29:59.050 --> 01:30:03.200 on the normal hot and dry summer days in California 01:30:03.200 --> 01:30:06.253 where large fires are still possible. 01:30:07.280 --> 01:30:10.310 We're not going to be executing PSPS to capture situations 01:30:10.310 --> 01:30:12.420 around the Butte fire, for example, 01:30:12.420 --> 01:30:15.330 around some of the other ranch Mendocino type fires 01:30:15.330 --> 01:30:18.470 where they're predominantly, you know, fuel driven 01:30:18.470 --> 01:30:20.730 they're not wind driven fires. 01:30:20.730 --> 01:30:24.620 And so I think, you know, you gotta look at PSPS 01:30:24.620 --> 01:30:28.690 through the lens of, you know we have these fire conditions 01:30:28.690 --> 01:30:29.720 that are out there, 01:30:29.720 --> 01:30:32.730 and then we have an offshore wind event pattern 01:30:32.730 --> 01:30:34.880 that usually leads to a red flag warning, 01:30:34.880 --> 01:30:36.000 high risk forecast 01:30:36.000 --> 01:30:38.197 from the Geographic Area Coordination Center 01:30:38.197 --> 01:30:40.630 and like critical and extreme 01:30:40.630 --> 01:30:43.130 warnings from the Storm Prediction Center. 01:30:43.130 --> 01:30:45.780 Whereas if we're in a drought situation 01:30:45.780 --> 01:30:50.780 the fuels and other things are just more receptive 01:30:51.060 --> 01:30:52.590 to large fires in general. 01:30:52.590 --> 01:30:53.905 It's like the baseline. 01:30:53.905 --> 01:30:57.230 We're starting at a higher baseline if you will, of danger 01:30:57.230 --> 01:31:01.110 but we need that wind component in order to really 01:31:01.110 --> 01:31:02.947 to necessitate shutting off the power 01:31:02.947 --> 01:31:05.510 'cause that increases the probability 01:31:05.510 --> 01:31:06.960 that we would have an outage. 01:31:09.110 --> 01:31:11.010 So hopefully I answered your question. 01:31:12.480 --> 01:31:14.633 Well, to the extent, yeah, thank you. 01:31:14.633 --> 01:31:18.710 To the extent that you can run more sensitivity analysis 01:31:18.710 --> 01:31:20.738 with all of the updated conditions 01:31:20.738 --> 01:31:23.050 and share them with us. 01:31:23.050 --> 01:31:24.050 That would be great. 01:31:27.610 --> 01:31:28.443 Yep. Yeah. 01:31:28.443 --> 01:31:29.800 We'll take that as follow up. 01:31:33.180 --> 01:31:34.013 This is Joyce. 01:31:34.013 --> 01:31:37.080 I think we wanted to turn now. 01:31:37.080 --> 01:31:41.603 I think Sumeet had an update to share? 01:31:45.610 --> 01:31:47.390 No, Joyce I think we can 01:31:47.390 --> 01:31:50.983 move on to the next speaker on the agenda. 01:31:52.870 --> 01:31:54.820 Oh, that, wasn't what I meant 01:31:54.820 --> 01:31:59.820 but we can turn now to some of the staff questions 01:32:00.630 --> 01:32:02.678 unless there was anything else that you needed 01:32:02.678 --> 01:32:05.830 to share at this point, Sumeet. 01:32:05.830 --> 01:32:08.263 So I was gonna turn it over to Shelby Chaste. 01:32:11.410 --> 01:32:13.130 Thank you, Joyce. 01:32:13.130 --> 01:32:15.560 Scott, this is probably a question for you. 01:32:15.560 --> 01:32:17.400 In a court filing PG and E 01:32:17.400 --> 01:32:20.240 says that the outage producing winds model 01:32:20.240 --> 01:32:25.240 was based on a sustained wind speed of 20 miles per hour. 01:32:25.320 --> 01:32:29.110 What was the basis for PG and E using 20 miles per hour 01:32:29.110 --> 01:32:31.310 as the input sustained wind speed 01:32:31.310 --> 01:32:35.113 when calculating the tree overstrike percentile? 01:32:37.530 --> 01:32:40.250 Yeah, that's a great question. 01:32:40.250 --> 01:32:43.830 And so, yes, our minimum, I just wanna clarify 01:32:43.830 --> 01:32:48.720 that that's not related to our outage producing wind model. 01:32:48.720 --> 01:32:51.600 It's more related to our minimum fire potential conditions. 01:32:51.600 --> 01:32:53.780 Those conditions that would be needed 01:32:54.780 --> 01:32:56.850 in order to then consider 01:32:56.850 --> 01:32:59.720 the vegetation overstrike potential. 01:32:59.720 --> 01:33:01.820 And essentially the basis in that, 01:33:01.820 --> 01:33:06.530 is that we've seen historically catastrophic fires occur 01:33:06.530 --> 01:33:08.820 at that level and actually below that level. 01:33:08.820 --> 01:33:11.370 Some of the notable incidents or incidents 01:33:13.040 --> 01:33:17.470 would be Zogg happened with sustained wind speeds 01:33:17.470 --> 01:33:21.400 around 20 miles per hour in that geographic area. 01:33:21.400 --> 01:33:23.810 If you look at some of the weather stations around there, 01:33:23.810 --> 01:33:24.810 the sustained wind speeds 01:33:24.810 --> 01:33:28.000 were actually below 20 miles per hour 01:33:28.000 --> 01:33:29.850 but when you take into account 01:33:29.850 --> 01:33:32.100 high resolution numerical weather prediction 01:33:32.100 --> 01:33:34.860 and look at the downslope component near 01:33:34.860 --> 01:33:37.923 where this fire happened, it's closer to 20 miles per hour. 01:33:40.630 --> 01:33:43.890 Another example is the Camp Fire. 01:33:43.890 --> 01:33:45.812 Before the Camp Fire ignited, 01:33:45.812 --> 01:33:50.812 sustained wind speed at the that Jarbo Gap rose, 01:33:51.740 --> 01:33:53.700 which is kind of a typically 01:33:53.700 --> 01:33:55.680 a notoriously windy weather station 01:33:55.680 --> 01:33:57.680 at the mouth of the Feather River Canyon 01:33:58.600 --> 01:34:02.135 had sustained wind speeds over 20. 01:34:02.135 --> 01:34:04.240 At one point, I think a couple hours before the ignition 01:34:04.240 --> 01:34:06.130 they were about 30 miles per hour. 01:34:06.130 --> 01:34:08.616 At 6:13 on November 8th, 01:34:08.616 --> 01:34:11.645 the sustained wind speed was 18 miles per hour 01:34:11.645 --> 01:34:13.810 when the Camp Fire ignited. 01:34:13.810 --> 01:34:16.760 And so, you know, based on looking at 01:34:16.760 --> 01:34:19.400 some of these historical incidents, 01:34:19.400 --> 01:34:21.550 we can have catastrophic fires occurring 01:34:21.550 --> 01:34:23.480 at those levels of wind speeds. 01:34:23.480 --> 01:34:25.930 So that's part of the basis. 01:34:25.930 --> 01:34:30.460 The other part of the basis is outlined in detail 01:34:30.460 --> 01:34:31.970 in our wildfire mitigation plan. 01:34:31.970 --> 01:34:33.783 I think again, in Section 2.A 01:34:35.840 --> 01:34:39.360 when we look at what agency 01:34:39.360 --> 01:34:41.157 like the National Weather Service 01:34:41.157 --> 01:34:44.170 and the Geographic Area Coordination Center 01:34:44.170 --> 01:34:45.920 as well as the Storm Prediction Center 01:34:45.920 --> 01:34:50.920 are using to justify their warnings around red flag warnings 01:34:51.010 --> 01:34:54.040 and high risk of significant fires, 01:34:54.040 --> 01:34:56.060 that's the GAC determination 01:34:57.580 --> 01:35:00.900 or extreme and critical fire weather warnings 01:35:00.900 --> 01:35:02.670 from the Storm Prediction Center. 01:35:02.670 --> 01:35:05.460 And when you look at all that data basically congeals 01:35:05.460 --> 01:35:08.610 if everyone's got a little bit different opinion 01:35:08.610 --> 01:35:11.160 but essentially the take home message is that 01:35:11.160 --> 01:35:13.290 it's around 20 miles per hour sustained 01:35:13.290 --> 01:35:15.870 where you start to see these warnings coming out 01:35:15.870 --> 01:35:19.310 from the federal agencies. 01:35:19.310 --> 01:35:21.193 The other components that, 01:35:21.193 --> 01:35:23.580 and the third kind of basis for that 01:35:23.580 --> 01:35:27.720 is looking at when we start to see an uptick 01:35:27.720 --> 01:35:32.240 in outage activity on the distribution network. 01:35:32.240 --> 01:35:34.860 And it occurs around that level, 01:35:34.860 --> 01:35:36.840 around that 20 mile per hour level 01:35:36.840 --> 01:35:39.230 when we start to get wind gusts. 01:35:39.230 --> 01:35:42.580 Well, we use sustained because that's inherently 01:35:42.580 --> 01:35:44.843 what our weather model outputs. 01:35:46.060 --> 01:35:48.640 And so when we get around that level 01:35:48.640 --> 01:35:51.150 that's when we start to see, we get on the curve 01:35:51.150 --> 01:35:54.270 of having unplanned outage activity. 01:35:54.270 --> 01:35:58.320 And it's, you know, something that we need to take 01:35:58.320 --> 01:35:59.810 into consideration too, 01:35:59.810 --> 01:36:02.880 is that that curve of when to outages it 01:36:02.880 --> 01:36:06.690 is pretty steep because when you think about it, 01:36:06.690 --> 01:36:10.830 the force that wind exerts on an object 01:36:10.830 --> 01:36:13.600 is proportional to the square of the velocity 01:36:13.600 --> 01:36:17.010 meaning that it's not a linear increase between the wind 01:36:17.010 --> 01:36:19.010 and the outage relationship. 01:36:19.010 --> 01:36:22.793 It's exponential, essentially a quadratic. 01:36:24.010 --> 01:36:26.290 And we found that relationship. 01:36:26.290 --> 01:36:28.700 We've determined that based on our historic look 01:36:28.700 --> 01:36:32.120 at wind speeds and outages. 01:36:32.120 --> 01:36:36.510 And so I hope those three items give you some basis 01:36:36.510 --> 01:36:40.590 of why that's our minimum fire potential conditions now. 01:36:40.590 --> 01:36:43.380 But as I stated we are evaluating 01:36:43.380 --> 01:36:45.670 those minimum fire potential conditions 01:36:45.670 --> 01:36:49.640 again, as part of our continuous improvement journey 01:36:49.640 --> 01:36:50.723 and cadence that I mentioned 01:36:50.723 --> 01:36:54.120 that we do every year to validate and justify 01:36:54.120 --> 01:36:55.670 any adjustments that we would make 01:36:55.670 --> 01:36:59.310 for operationalizing in 2021. 01:36:59.310 --> 01:37:01.463 So I hope I addressed your question. 01:37:03.580 --> 01:37:04.413 Yes. Thank you. 01:37:04.413 --> 01:37:09.060 My second question is which tools or enhancements, if any, 01:37:09.060 --> 01:37:12.010 are needed to existing models for PG and E 01:37:12.010 --> 01:37:14.963 to implement the proposed probation conditions? 01:37:19.720 --> 01:37:21.700 Yeah. So thinking about... 01:37:21.700 --> 01:37:23.163 That's a great question. 01:37:24.293 --> 01:37:27.920 So, you know, it's one thing to consider 01:37:27.920 --> 01:37:32.280 the you know, how, or I guess the methodology 01:37:32.280 --> 01:37:36.630 of how you would consider overstrike. 01:37:36.630 --> 01:37:39.730 One thing that, you know, I always do is look at it 01:37:39.730 --> 01:37:40.860 from an operational lens. 01:37:40.860 --> 01:37:42.780 How would you actually operationalize this? 01:37:42.780 --> 01:37:46.110 And I think we've got a very good path 01:37:46.110 --> 01:37:50.240 in order to operationalize this model. 01:37:50.240 --> 01:37:54.020 So I think there are some adjustments 01:37:54.020 --> 01:37:57.680 that my internal team should we move forward 01:37:57.680 --> 01:37:58.700 with implementing this. 01:37:58.700 --> 01:38:01.610 If these proposed conditions do become conditions 01:38:01.610 --> 01:38:03.554 we would have to consider 01:38:03.554 --> 01:38:08.250 this in our kind of modeling framework, if you will. 01:38:08.250 --> 01:38:10.407 So to give you a little bit of background, 01:38:10.407 --> 01:38:14.210 we are analyzing the weather and fuels 01:38:14.210 --> 01:38:18.270 on a two by two kilometer basis every hour, 01:38:18.270 --> 01:38:19.300 going out for days. 01:38:19.300 --> 01:38:21.398 And we would simply need to add in some logic 01:38:21.398 --> 01:38:22.970 that takes into account 01:38:22.970 --> 01:38:25.630 where we have that 70 percentile and above. 01:38:25.630 --> 01:38:27.940 And it's something that my data science team 01:38:28.780 --> 01:38:31.270 is more than capable of adding in and making sure 01:38:31.270 --> 01:38:33.083 that we do that in a quality way. 01:38:34.320 --> 01:38:39.320 The other, I think addition is that we would need to do 01:38:39.560 --> 01:38:43.290 before July 1st, when we're supposed to execute 01:38:43.290 --> 01:38:44.660 on these proposed conditions, 01:38:44.660 --> 01:38:47.420 is ensuring that we have visibility 01:38:47.420 --> 01:38:50.410 in real time of priority one, priority two trees 01:38:50.410 --> 01:38:53.920 and we have good visibility of making that a reality. 01:38:53.920 --> 01:38:56.850 And so I think those are the two items that I would call 01:38:56.850 --> 01:38:58.250 out to answer your question. 01:39:00.141 --> 01:39:00.974 Great. Thank you. 01:39:00.974 --> 01:39:04.603 I'll turn it over to Joyce for other questions. 01:39:09.110 --> 01:39:11.520 Thank you, Shelby. 01:39:11.520 --> 01:39:13.840 So as of this workshop stakeholders 01:39:13.840 --> 01:39:17.110 have been given multiple different estimates as 01:39:17.110 --> 01:39:20.400 to what percentage additional PSPS 01:39:21.270 --> 01:39:24.500 these probation conditions might cause. 01:39:24.500 --> 01:39:26.460 Why has there been so much change 01:39:26.460 --> 01:39:29.783 and how is the predicted figure determined? 01:39:33.072 --> 01:39:34.750 Yeah, that's a great question. 01:39:34.750 --> 01:39:37.250 Yeah, I think what we've presented today 01:39:37.250 --> 01:39:40.510 is the best available information we have. 01:39:40.510 --> 01:39:44.030 And I hope through, you know the conversation 01:39:44.030 --> 01:39:46.768 that we've had today, you know, 01:39:46.768 --> 01:39:50.180 determining the potential impact by looking at 10 years 01:39:50.180 --> 01:39:54.760 in the past using hourly data is pretty complicated. 01:39:54.760 --> 01:39:56.840 It's actually very complicated 01:39:56.840 --> 01:39:59.540 and it takes a lot of data science 01:39:59.540 --> 01:40:03.740 and other things in order to make it happen. 01:40:03.740 --> 01:40:05.890 And in some of the previous, 01:40:05.890 --> 01:40:10.200 I think the information that was shared earlier 01:40:10.200 --> 01:40:12.550 the numbers might've been a little bit different. 01:40:12.550 --> 01:40:16.110 We actually found a data corruption issue 01:40:16.110 --> 01:40:19.840 on one day in January, 2014 01:40:19.840 --> 01:40:23.410 that was disrupting the inclusion of a couple of events 01:40:23.410 --> 01:40:26.190 and we've since identified and fixed that issue. 01:40:26.190 --> 01:40:28.030 But that's just some of the things 01:40:28.030 --> 01:40:31.120 when we're working under very short timelines can happen. 01:40:31.120 --> 01:40:34.080 But we did do believe now we've corrected 01:40:34.080 --> 01:40:37.270 all of those issues and the information 01:40:37.270 --> 01:40:39.750 that you have in front of you today 01:40:39.750 --> 01:40:43.120 is the best information and the most accurate information 01:40:43.120 --> 01:40:43.953 we have to date. 01:40:43.953 --> 01:40:46.250 So I would utilize the materials 01:40:46.250 --> 01:40:50.430 that we're reviewing today as forming the basis 01:40:50.430 --> 01:40:52.830 of your conclusion of these proposed conditions. 01:40:56.070 --> 01:40:58.560 Thank you for that clarification. 01:40:58.560 --> 01:40:59.483 We appreciate it. 01:41:00.460 --> 01:41:04.240 I know you've touched briefly when you were discussing 01:41:04.240 --> 01:41:09.240 with Shelby about changing the wind speed. 01:41:09.330 --> 01:41:13.420 So Probation Condition 12 says windstorm. 01:41:13.420 --> 01:41:17.090 So how is PG and E understanding the applicability 01:41:17.090 --> 01:41:20.550 of that term and is it to be measured 01:41:20.550 --> 01:41:22.230 by sustained wind speed? 01:41:22.230 --> 01:41:23.590 Is it wind gust? 01:41:23.590 --> 01:41:25.990 Is it a wind pressure? 01:41:25.990 --> 01:41:28.490 Can you just articulate a little more 01:41:28.490 --> 01:41:32.460 on this particular issue regarding how PG and E 01:41:32.460 --> 01:41:36.110 is understanding what the probation conditions 01:41:36.110 --> 01:41:37.563 call a wind storm? 01:41:38.955 --> 01:41:42.540 Sure. Yeah. Excellent question. 01:41:42.540 --> 01:41:45.020 And upon reading the language windstorm 01:41:45.020 --> 01:41:49.193 to me as a meteorologist is a bit nebulous. 01:41:50.760 --> 01:41:53.640 However, we know that the spirit of this intent 01:41:53.640 --> 01:41:57.750 of the proposed conditions is not to shut off the power 01:41:57.750 --> 01:42:00.980 during winter wind storms. 01:42:00.980 --> 01:42:05.420 And so, you know, we believe that this is indicative 01:42:05.420 --> 01:42:09.470 of a dry off shore or dry windstorm 01:42:09.470 --> 01:42:12.520 where typically a red flag warning 01:42:12.520 --> 01:42:16.150 or other high risk indications from external sources 01:42:16.150 --> 01:42:19.690 and federal agencies would be present for. 01:42:19.690 --> 01:42:23.840 And, you know, going back to the answer 01:42:23.840 --> 01:42:26.710 around justifying the 20 mile per hour 01:42:26.710 --> 01:42:29.650 sustained minimum fire potential condition wind speed, 01:42:29.650 --> 01:42:32.070 some of that same logic applies to, you know 01:42:32.070 --> 01:42:35.910 those are the conditions that we would typically 01:42:35.910 --> 01:42:38.123 see when there's a red flag warning issued. 01:42:54.610 --> 01:42:55.770 Thank you. 01:42:55.770 --> 01:42:59.260 Yeah, and I realized I didn't address, sorry 01:42:59.260 --> 01:43:01.940 the wind gusts portion of your comment 01:43:03.870 --> 01:43:07.570 and maybe this is more for a future kind of parking lot item 01:43:07.570 --> 01:43:12.570 but the reason that we are utilizing wind speed right now 01:43:12.680 --> 01:43:14.930 is that that is directly output 01:43:14.930 --> 01:43:17.249 from our numerical weather prediction model. 01:43:17.249 --> 01:43:22.249 We also evaluate wind gusts too and we continue to do so. 01:43:22.660 --> 01:43:25.770 In fact, in our 2021 wildfire mitigation plan 01:43:25.770 --> 01:43:29.710 you could read, I think it's in Section 7.3.2 01:43:32.320 --> 01:43:35.060 and another sub bullet, another sub number 01:43:35.060 --> 01:43:38.100 about some of the improvements that we're executing 01:43:38.100 --> 01:43:39.490 in that space this year 01:43:39.490 --> 01:43:41.220 which I'm very excited about. 01:43:41.220 --> 01:43:44.880 A couple of those is developing machine learning 01:43:44.880 --> 01:43:48.588 wind gust models that take the output 01:43:48.588 --> 01:43:53.380 from our high resolution weather prediction model 01:43:53.380 --> 01:43:56.240 that is outputting generally a sustained wind 01:43:56.240 --> 01:44:00.030 and translating it into a wind gust for weather stations 01:44:01.140 --> 01:44:04.610 and doing it in a way that takes into account, you know, 01:44:04.610 --> 01:44:06.677 upper level winds of the atmosphere, 01:44:06.677 --> 01:44:09.810 the terrain that that weather station is around 01:44:09.810 --> 01:44:12.060 and other components that are kind of feeding 01:44:12.060 --> 01:44:13.490 into the machine learning model. 01:44:13.490 --> 01:44:18.490 And so we're making some large strides 01:44:19.110 --> 01:44:20.580 I believe this year in translating 01:44:20.580 --> 01:44:23.350 from when sustained wind speeds or wind gusts 01:44:23.350 --> 01:44:28.037 and whatever we feel more confident in forecasting, 01:44:28.037 --> 01:44:30.900 that's what we'll use to form the basis 01:44:30.900 --> 01:44:32.950 of our minimum fire potential conditions. 01:44:34.000 --> 01:44:36.410 So I hope that addresses the wind gusts 01:44:36.410 --> 01:44:38.260 versus sustained wind speed question. 01:44:40.720 --> 01:44:41.553 Oh yes. Thank you. 01:44:41.553 --> 01:44:42.920 I think it does, Scott. 01:44:42.920 --> 01:44:45.290 Thanks for elaborating on that. 01:44:45.290 --> 01:44:50.290 So what is the impact of using 2019 or 2020 LiDAR data 01:44:50.680 --> 01:44:54.070 and what are PG and E plans for the future use of LiDAR 01:44:54.070 --> 01:44:57.523 and it's vegetation management programs? 01:45:00.350 --> 01:45:04.250 Great. Yeah, that one's a little outside my swim lane. 01:45:04.250 --> 01:45:07.260 Sumeet, do you mind taking that one? 01:45:07.260 --> 01:45:09.000 Yup. I was gonna jump right in, man. 01:45:09.000 --> 01:45:11.280 So, thank you Joyce for that question. 01:45:11.280 --> 01:45:15.160 So we have a different frequency between transmission 01:45:15.160 --> 01:45:17.760 and distribution so as part of our transmission vegetation 01:45:17.760 --> 01:45:20.120 management program, Joyce, 01:45:20.120 --> 01:45:23.350 we are capturing LiDAR information 01:45:23.350 --> 01:45:26.570 on a much much more frequent cadence every year 01:45:26.570 --> 01:45:28.510 or once every two years. 01:45:28.510 --> 01:45:30.940 And we use the strike potential trees 01:45:30.940 --> 01:45:33.910 that are identified coming out of LiDAR on the trends 01:45:35.150 --> 01:45:38.620 as the mechanism by which we evaluate the health 01:45:38.620 --> 01:45:40.400 of all of those strike potential trees 01:45:40.400 --> 01:45:43.930 but the density of strike potential trees 01:45:43.930 --> 01:45:47.410 between our distribution is much different 01:45:48.285 --> 01:45:49.740 than transmission. 01:45:49.740 --> 01:45:51.310 So when we look at transmission 01:45:52.200 --> 01:45:54.450 we have 500 hundred miles roughly of overhang 01:45:55.517 --> 01:45:57.350 by far throughout districts 01:45:57.350 --> 01:46:01.647 and we have about 365,000 strike potential trees, right? 01:46:01.647 --> 01:46:04.010 So you do that quick math, if the density 01:46:04.010 --> 01:46:08.290 of about 65 to 66 trees on average per mile. 01:46:08.290 --> 01:46:12.530 When you look at the distribution LiDAR data, 01:46:12.530 --> 01:46:17.530 25,500, 5.3 million you do that math 01:46:17.540 --> 01:46:22.540 it's more than 205 to 207 trees for miles 01:46:22.870 --> 01:46:26.963 three on distribution as opposed to transmission. 01:46:26.963 --> 01:46:29.500 So our intent on transmission is to continue to use LiDAR 01:46:29.500 --> 01:46:32.290 on a much more frequent cadence for distribution. 01:46:32.290 --> 01:46:35.830 The first time we ever captured that data was in 2019 01:46:35.830 --> 01:46:37.730 and it took quite a bit of time 01:46:37.730 --> 01:46:41.220 to analyze all of that LiDAR data 01:46:41.220 --> 01:46:43.286 because it's not a quick analysis 01:46:43.286 --> 01:46:45.750 especially when we talk about that scale. 01:46:45.750 --> 01:46:48.877 So that data became available middle of 2020 01:46:48.877 --> 01:46:51.200 and we anticipate to establish 01:46:51.200 --> 01:46:54.530 what the right frequency is going forward 01:46:54.530 --> 01:46:57.840 because part of this is that we still have a lot of areas 01:46:57.840 --> 01:47:00.250 with tree canopy and as we remove 01:47:00.250 --> 01:47:01.940 that overhang and tree canopy and have 01:47:01.940 --> 01:47:04.360 the enhanced vegetation management program, 01:47:04.360 --> 01:47:08.640 the intent is for us to evolve our distribution 01:47:08.640 --> 01:47:10.540 vegetation management program, 01:47:10.540 --> 01:47:12.850 to look a lot more like transition. 01:47:12.850 --> 01:47:13.940 We're just not there yet. 01:47:13.940 --> 01:47:17.754 So our intent would be to capture LIDAR. 01:47:17.754 --> 01:47:19.310 We don't have plans to do that in 2021. 01:47:19.310 --> 01:47:22.530 We think the data that we have is pretty robust 01:47:22.530 --> 01:47:25.300 based on what we captured and then going into 2022 01:47:25.300 --> 01:47:27.140 and beyond we will set that established frequency 01:47:27.140 --> 01:47:28.427 for distribution. 01:47:34.013 --> 01:47:34.846 That help? 01:47:37.200 --> 01:47:38.033 That helped a lot. 01:47:38.033 --> 01:47:39.019 Thank you. 01:47:39.019 --> 01:47:40.060 Most welcome. 01:47:40.060 --> 01:47:42.600 I think it's already in some of your materials 01:47:42.600 --> 01:47:47.600 where you discuss the accuracy of the LiDAR measurements. 01:47:48.530 --> 01:47:53.530 I think it mentioned that you not only use LiDAR 01:47:54.110 --> 01:47:57.080 but you did a certain amount of field verification 01:47:57.080 --> 01:47:58.620 on the accuracy of LiDAR. 01:47:58.620 --> 01:48:00.573 Can you just speak to that briefly? 01:48:02.710 --> 01:48:06.288 Yeah Joyce, so when you look at the accuracy 01:48:06.288 --> 01:48:11.288 of the aerial LiDAR, it's one of the best available methods 01:48:13.730 --> 01:48:16.010 that are available commercially 01:48:16.010 --> 01:48:19.393 to be able to leverage this data set up scale. 01:48:20.300 --> 01:48:23.960 You know, we've also looked at additional technology 01:48:23.960 --> 01:48:25.670 through satellite 01:48:25.670 --> 01:48:27.890 and there's been several different entities 01:48:27.890 --> 01:48:30.316 that have approached us in that capacity. 01:48:30.316 --> 01:48:31.930 We're open to those discussions 01:48:31.930 --> 01:48:36.447 but we have not yet quite seen the same level of accuracy. 01:48:36.447 --> 01:48:39.440 You know, the one thing that we have identified 01:48:39.440 --> 01:48:44.180 is as we go out and have our professional arborists 01:48:44.180 --> 01:48:46.440 that put boots on the ground 01:48:46.440 --> 01:48:49.540 as part of our enhanced vegetation management program, 01:48:49.540 --> 01:48:53.589 where they're identifying the strike potential trees 01:48:53.589 --> 01:48:58.589 on a overall aggregate basis for the 4,300 miles. 01:48:58.910 --> 01:49:01.390 And we've looked at a subset of that dataset, 01:49:01.390 --> 01:49:04.795 roughly 1500 to 1800 miles. 01:49:04.795 --> 01:49:08.590 You know, we have identified that the aerial LiDAR 01:49:08.590 --> 01:49:13.000 is in certain cases has underestimated the number of trees 01:49:13.000 --> 01:49:16.120 and that happens in one of the slides 01:49:16.120 --> 01:49:19.130 that I was discussing previously. 01:49:19.130 --> 01:49:23.660 I think it was slide nine, I believe, 01:49:23.660 --> 01:49:25.859 which shows the canopy and the challenge 01:49:25.859 --> 01:49:28.395 of the canopy is the LiDAR doesn't have the ability 01:49:28.395 --> 01:49:31.210 to be able to see the tree trunk 01:49:31.210 --> 01:49:33.320 and capture that data point. 01:49:33.320 --> 01:49:36.550 So there's a over and under estimation 01:49:36.550 --> 01:49:39.330 and that occurs as a result of that. 01:49:39.330 --> 01:49:43.450 So we have found in some parts of the circuit 01:49:43.450 --> 01:49:46.970 where the aerial LiDAR could have underestimated 01:49:46.970 --> 01:49:50.393 the strike potential trees by 15 to 20%. 01:49:51.760 --> 01:49:54.300 But on a relative basis when you look at 01:49:54.300 --> 01:49:58.090 the overall aggregate 25,500 01:49:58.090 --> 01:50:02.470 it's a fairly good data set to compare 01:50:02.470 --> 01:50:06.280 which circuit has a higher density of trees 01:50:06.280 --> 01:50:07.940 versus those that have the medium density 01:50:07.940 --> 01:50:09.030 versus a lower density. 01:50:09.030 --> 01:50:11.145 So it's a very effective means 01:50:11.145 --> 01:50:14.330 to be able to do a relative comparison. 01:50:14.330 --> 01:50:17.028 When you do an absolute comparison 01:50:17.028 --> 01:50:19.005 that's where there's additional opportunities 01:50:19.005 --> 01:50:21.833 to further improve on that dataset. 01:50:24.990 --> 01:50:25.823 I apologize. 01:50:25.823 --> 01:50:28.550 That slide was slide nine on my version 01:50:28.550 --> 01:50:33.550 but I think if you go three more, four more slides forward 01:50:34.583 --> 01:50:36.560 that's the slide I was talking about. 01:50:36.560 --> 01:50:37.713 I'm sorry about that. 01:50:39.440 --> 01:50:40.273 One more. 01:50:42.473 --> 01:50:43.306 That's it. 01:50:49.440 --> 01:50:51.390 Did you have a question Commissioner? 01:50:53.870 --> 01:50:55.740 I did. I wanted to make sure that you finished 01:50:55.740 --> 01:50:57.340 your line of questioning though. 01:51:02.420 --> 01:51:04.380 The only remaining question I had 01:51:09.016 --> 01:51:12.570 was about residual tree overstrike exposure. 01:51:12.570 --> 01:51:15.610 So on slide 30, which is in the appendix 01:51:17.850 --> 01:51:19.320 it would help to have more clarity 01:51:19.320 --> 01:51:22.323 on what overstrike means in this context. 01:51:23.250 --> 01:51:28.250 And maybe just describe how the residual risk is defined. 01:51:30.890 --> 01:51:35.440 I think as stakeholders read that 01:51:38.840 --> 01:51:40.840 the 10% can mean different things. 01:51:40.840 --> 01:51:44.520 Is it 10% risk of an overstrike outage 01:51:44.520 --> 01:51:47.520 or 10% risk of an overstrike cause wildfire 01:51:47.520 --> 01:51:50.033 maybe just give us some context on that slide. 01:51:53.670 --> 01:51:54.767 Sure. Yes, Scott. 01:51:54.767 --> 01:51:55.880 And this is Scott. 01:51:55.880 --> 01:51:57.300 Yeah, I can address this. 01:51:57.300 --> 01:52:00.330 So, you know, one of the things that we wanted to do 01:52:00.330 --> 01:52:05.330 when looking at overstrike is, you know, determine, 01:52:05.790 --> 01:52:08.654 you know, one thing is looking at the increase 01:52:08.654 --> 01:52:11.480 in potential impact to customers. 01:52:11.480 --> 01:52:15.660 And that's what the orange line represents when we move 01:52:15.660 --> 01:52:19.620 from the 2020 10 year baseline 01:52:19.620 --> 01:52:23.680 which is on the far left portion of the chart to looking 01:52:23.680 --> 01:52:28.480 at considering all the way to the 50th percentile 01:52:31.180 --> 01:52:35.960 above tree overstrike risk and what that would mean 01:52:35.960 --> 01:52:40.513 in terms of increase in customer hours relative to baseline. 01:52:41.680 --> 01:52:44.800 And so I'll explain the orange line first 01:52:44.800 --> 01:52:48.070 and I'll come back to the blue line which is your question. 01:52:48.070 --> 01:52:50.030 But the orange line, essentially, when you get 01:52:50.030 --> 01:52:53.000 to the 50th percentile, we're almost doubling 01:52:53.000 --> 01:52:58.000 the customer, our dimension of public safety power shutoff. 01:52:59.670 --> 01:53:02.840 This is just a one dimension of of PSPS 01:53:02.840 --> 01:53:04.573 and there's many to digest here. 01:53:06.040 --> 01:53:08.870 However, you know, we want to also look at 01:53:08.870 --> 01:53:13.230 how much risk reduction that we're gaining by doing that. 01:53:13.230 --> 01:53:16.770 And one way is by evaluating 01:53:16.770 --> 01:53:18.880 the amount of outage activity that's occurring 01:53:18.880 --> 01:53:20.960 in that geographic footprint 01:53:20.960 --> 01:53:24.373 that's represented by the percentile. 01:53:26.670 --> 01:53:29.950 And in order to calculate this, 01:53:29.950 --> 01:53:34.950 is essentially we're looking at the number of, 01:53:35.940 --> 01:53:39.350 going back over the 10 year period, 01:53:39.350 --> 01:53:42.730 the number of vegetation caused outages 01:53:42.730 --> 01:53:47.530 within that geographic footprint that's representative 01:53:47.530 --> 01:53:50.310 of that percentile and above value. 01:53:50.310 --> 01:53:53.020 So for example, our baseline model 01:53:53.020 --> 01:53:55.250 we believe that didn't take 01:53:55.250 --> 01:53:57.070 into account vegetation directly 01:53:57.070 --> 01:53:59.160 but considered outage producing wind 01:53:59.160 --> 01:54:00.713 and fire potential index. 01:54:01.940 --> 01:54:05.820 Essentially 70% of vegetation cause outages are happening 01:54:05.820 --> 01:54:07.590 within that geographic footprint 01:54:07.590 --> 01:54:10.823 that's covered by the model. 01:54:11.820 --> 01:54:13.003 The inverse of that is that 01:54:13.003 --> 01:54:16.610 there's 30% of vegetation caused outages 01:54:16.610 --> 01:54:18.702 that are happening outside of that geographic footprint 01:54:18.702 --> 01:54:23.702 which we call the residual tree overstrike risk here. 01:54:25.190 --> 01:54:29.710 And so this is one way to try to estimate 01:54:31.730 --> 01:54:35.510 you know, with PSPS, how much risk reduction we're seeing. 01:54:35.510 --> 01:54:38.380 There's multiple other ways to calculate this 01:54:38.380 --> 01:54:41.610 but this is one way that we've looked at it. 01:54:41.610 --> 01:54:43.865 And so when we start to go down the chart, 01:54:43.865 --> 01:54:47.660 essentially, you know, all the way down to 50th percent 01:54:47.660 --> 01:54:51.920 because we're expanding the geographic area, if you will 01:54:54.200 --> 01:54:56.400 overstrike we're essentially capturing more risks, 01:54:56.400 --> 01:54:59.770 we're capturing a larger geographic area 01:54:59.770 --> 01:55:02.843 where vegetation outages are happening. 01:55:04.080 --> 01:55:09.080 And only 3% of outages vegetation related 01:55:10.410 --> 01:55:15.410 are not happening in the bottom 50th percentile 01:55:15.880 --> 01:55:20.880 of geographic area or geographic overstrike risk 01:55:20.910 --> 01:55:24.940 where the majority 97% of vegetation cause outages 01:55:24.940 --> 01:55:27.740 are happening in the top 50th percentile. 01:55:27.740 --> 01:55:30.680 And so that's what the 10 percentile essentially means 01:55:30.680 --> 01:55:34.922 if we hone in on 70, that's what the 10 means 01:55:34.922 --> 01:55:37.670 is then we hone in on the 70th percentile 01:55:37.670 --> 01:55:41.873 that 70 percentile and above geographic area. 01:55:42.800 --> 01:55:46.280 And that again is hopefully more simply 01:55:47.660 --> 01:55:49.340 that's the area where we have more trees 01:55:49.340 --> 01:55:51.530 that can strike our lines. 01:55:51.530 --> 01:55:56.530 90% of vegetation caused outages are occurring 01:55:56.830 --> 01:55:59.700 within the 70th percentile and above, 01:55:59.700 --> 01:56:02.350 meaning that there's a 10% 01:56:05.600 --> 01:56:08.020 that is not going to be captured directly 01:56:08.020 --> 01:56:10.453 by the current framework. 01:56:12.320 --> 01:56:16.940 And so hopefully with my explanation of percentiles 01:56:16.940 --> 01:56:18.960 and other things I didn't muddy the waters 01:56:18.960 --> 01:56:20.070 but hopefully that gives you a sense 01:56:20.070 --> 01:56:22.223 of how it was calculated. 01:56:24.680 --> 01:56:25.910 Thank you for walking through that. 01:56:25.910 --> 01:56:27.050 Appreciate it. 01:56:27.050 --> 01:56:28.400 Commissioner Rechtschaffen. 01:56:30.673 --> 01:56:34.630 I had a question which may be review or clarification 01:56:34.630 --> 01:56:36.690 or maybe I just don't understand it exactly 01:56:36.690 --> 01:56:38.747 but I wanted to go back Scott 01:56:38.747 --> 01:56:43.747 and Sumeet commented about this slide 17 or 17 in my deck, 01:56:45.190 --> 01:56:49.510 which is implementation of the proposed PSPS 21 01:56:51.840 --> 01:56:53.423 decision-making process. 01:56:54.390 --> 01:56:58.070 And I just wanna drill down on the new box, 01:56:58.070 --> 01:57:01.910 which is an or as opposed to put aside 01:57:01.910 --> 01:57:03.810 the black foreign conditions 01:57:03.810 --> 01:57:05.930 your current practices you calculate 01:57:05.930 --> 01:57:09.140 this distribution large fire probability. 01:57:09.140 --> 01:57:11.260 And that encompasses a number of factors 01:57:11.260 --> 01:57:15.140 that go beyond an area meeting a minimum fire potential, 01:57:15.140 --> 01:57:16.020 that's the baseline 01:57:16.020 --> 01:57:17.460 but then you look at the probability 01:57:17.460 --> 01:57:22.460 of whether fuels land use types and wind speed 01:57:24.800 --> 01:57:26.330 and that's the first box. 01:57:26.330 --> 01:57:28.535 And then the fourth box is in the or 01:57:28.535 --> 01:57:32.730 the box in the blue at the bottom is in or, 01:57:32.730 --> 01:57:36.380 the question I have and Sumeet touched on this a little bit 01:57:36.380 --> 01:57:39.710 is to what extent are those other risk factors 01:57:39.710 --> 01:57:44.637 being used in combination with the overstrike criteria 01:57:47.330 --> 01:57:49.330 to inform the PSPS. 01:57:49.330 --> 01:57:53.990 As I heard Sumeet talk about the narrowing the universe 01:57:53.990 --> 01:57:57.910 of the 5.3 million trees with overstrike capability 01:57:57.910 --> 01:58:00.050 on the distribution network 01:58:00.050 --> 01:58:04.360 but I'm not quite sure how these other risk factors merged 01:58:04.360 --> 01:58:09.360 with the overstrike considerations in box four. 01:58:10.760 --> 01:58:13.262 So may I apologize if this is already been 01:58:13.262 --> 01:58:15.197 sort of gone over this already 01:58:15.197 --> 01:58:17.447 but maybe you could walk us through it again. 01:58:18.870 --> 01:58:20.430 Yeah, absolutely. 01:58:20.430 --> 01:58:23.030 And I think it would actually add a lot of value 01:58:23.030 --> 01:58:25.850 to walk through this again. 01:58:25.850 --> 01:58:30.220 And yeah, so essentially I think you're thinking about 01:58:30.220 --> 01:58:34.100 the operator, the OR operator exactly right. 01:58:34.100 --> 01:58:38.460 It's after minimum fire potential conditions are met, 01:58:38.460 --> 01:58:41.486 it's either one of these things that can bring 01:58:41.486 --> 01:58:44.083 a distribution line into scope. 01:58:45.790 --> 01:58:49.670 The core model, the thing that's going to bring most lines 01:58:49.670 --> 01:58:51.330 into scope will continue 01:58:51.330 --> 01:58:55.460 to be our large fire probability model for distribution. 01:58:55.460 --> 01:58:57.700 And we use a value of six 01:58:57.700 --> 01:59:01.080 and that is the fire potential index multiplied by OBW. 01:59:01.080 --> 01:59:03.395 And so if we have any values and forecasts 01:59:03.395 --> 01:59:06.733 that are greater than a value of six 01:59:06.733 --> 01:59:08.810 then those lines are gonna be considered a scope, 01:59:08.810 --> 01:59:11.660 we're gonna start communication with customers. 01:59:11.660 --> 01:59:14.600 Or we look at distribution Black Swan. 01:59:14.600 --> 01:59:19.600 And so that's not dependent on meeting or not meeting 01:59:20.370 --> 01:59:22.437 the box two. 01:59:22.437 --> 01:59:25.380 So if we're meeting distribution Black Swan only 01:59:25.380 --> 01:59:28.780 then that would be considered in scope 01:59:28.780 --> 01:59:31.443 or if we're meeting direct vegetation 01:59:31.443 --> 01:59:33.380 then that would be considered. 01:59:33.380 --> 01:59:37.080 And you'll see that there's or's inside of that box too 01:59:37.080 --> 01:59:39.410 where if we're meeting 01:59:39.410 --> 01:59:42.010 the minimum fire potential conditions only 01:59:43.610 --> 01:59:47.470 and let's say only direct vegetation consideration 01:59:47.470 --> 01:59:49.950 we would have to consider what's actually driving it 01:59:49.950 --> 01:59:52.700 is it the 70th percentile and above, 01:59:52.700 --> 01:59:55.640 the priority one or the priority two. 01:59:55.640 --> 01:59:57.763 So either one of those things, 01:59:59.250 --> 02:00:01.830 either one of those three things 02:00:01.830 --> 02:00:05.100 is the proposed 2021 criteria. 02:00:05.100 --> 02:00:08.230 And it's activated, it's flipped on, if you will 02:00:08.230 --> 02:00:11.510 if minimum fire potential conditions are met 02:00:11.510 --> 02:00:14.210 regardless of what's happening 02:00:14.210 --> 02:00:17.973 in the other two boxes box two and box three. 02:00:19.510 --> 02:00:23.970 Now, one of the other things that we're doing this year 02:00:23.970 --> 02:00:27.243 that we can and to Sumeet's point, 02:00:28.540 --> 02:00:33.540 we can identify those areas that are being identified 02:00:33.920 --> 02:00:37.280 for in scope or PSPS under this methodology 02:00:37.280 --> 02:00:39.261 that are only being pulled in, 02:00:39.261 --> 02:00:40.920 basically identified for scope 02:00:40.920 --> 02:00:43.880 for priority one and priority two trees. 02:00:43.880 --> 02:00:47.070 And we can prioritize those such that we can 02:00:47.070 --> 02:00:49.220 send vegetation crews out 02:00:49.220 --> 02:00:53.660 before the PSPS event arrives to mitigate those trees 02:00:53.660 --> 02:00:57.810 such that we can keep those lines hopefully energized 02:00:57.810 --> 02:01:01.210 during a PSPS event that would only be meeting 02:01:01.210 --> 02:01:04.453 that priority one and priority two classification 02:01:04.453 --> 02:01:05.833 or threshold. 02:01:07.880 --> 02:01:11.857 And I'll stop there and see how I did my answer. 02:01:15.782 --> 02:01:17.536 Okay, thank you. That's helpful. 02:01:17.536 --> 02:01:21.700 You obviously can't mitigate all the potential 02:01:21.700 --> 02:01:25.077 over the trees with potential overstride capacity 02:01:25.077 --> 02:01:28.740 given the volume of those in the same way you can do 02:01:28.740 --> 02:01:30.883 with priority one and priority two. 02:01:31.750 --> 02:01:34.280 So there's a large universe of trees 02:01:34.280 --> 02:01:37.020 that could trigger this other category. 02:01:37.020 --> 02:01:42.020 And if I'm just reducing this to an oversimplification, 02:01:42.643 --> 02:01:47.643 it's a much cruder criteria than your highly sophisticated 02:01:47.850 --> 02:01:51.470 large distribution fire profitability methodology 02:01:51.470 --> 02:01:54.860 which relies on tasks, climate events and machine learning. 02:01:54.860 --> 02:01:58.370 And this does to some extent to get you into the door 02:01:58.370 --> 02:02:00.525 but then once you add a minimum criteria, 02:02:00.525 --> 02:02:05.525 it's a much more simplistic trigger. 02:02:05.810 --> 02:02:08.003 Is that a fair way of thinking about it? 02:02:09.320 --> 02:02:12.410 Yeah, I would say it's a simpler way to... 02:02:13.540 --> 02:02:15.130 Yeah, it's more simple 02:02:15.130 --> 02:02:18.330 than our large fire probability model. 02:02:18.330 --> 02:02:19.300 That is correct. 02:02:19.300 --> 02:02:21.425 And just to put in context, the 70 percentile 02:02:21.425 --> 02:02:24.650 and the comment around the volume 02:02:25.730 --> 02:02:27.670 I can't remember if I mentioned this 02:02:27.670 --> 02:02:28.940 or if Sumeet mentioned it or not 02:02:28.940 --> 02:02:31.580 but at the 70th percentile of overstrike, 02:02:32.710 --> 02:02:35.130 the number, the absolute number of overstrike 02:02:35.130 --> 02:02:39.980 that's calculated at the 70th percentile is up 10,000 feet 02:02:39.980 --> 02:02:41.610 of overstrike, 02:02:41.610 --> 02:02:46.610 which is a little under two miles of tree length 02:02:47.910 --> 02:02:49.770 that can strike our line, essentially. 02:02:49.770 --> 02:02:54.770 So yes, the number is still quite staggering 02:02:54.940 --> 02:02:59.348 and I don't think it's... 02:02:59.348 --> 02:03:01.600 Well, maybe I'll leave it there 02:03:03.020 --> 02:03:05.910 If I just add onto that Scott and Commissioner 02:03:05.910 --> 02:03:07.760 you're thinking about the right way, right? 02:03:07.760 --> 02:03:12.200 Which is step one is the minimum gating criteria, right? 02:03:12.200 --> 02:03:14.670 Those conditions have to exist 02:03:14.670 --> 02:03:19.550 to get to box two, three or four. 02:03:19.550 --> 02:03:23.480 So once those minimum conditions are met, as it starts 02:03:23.480 --> 02:03:28.290 you know, that Scott articulated the overstrike potential, 02:03:28.290 --> 02:03:31.680 I mean, think about that as if a tree is tall enough 02:03:31.680 --> 02:03:33.160 but not far enough 02:03:33.160 --> 02:03:38.160 and just by the sheer fact that that tree exists 02:03:39.650 --> 02:03:41.150 poses a potential risk. 02:03:41.150 --> 02:03:42.280 So you're absolutely right. 02:03:42.280 --> 02:03:45.980 It is kind of more of that bright line approach. 02:03:45.980 --> 02:03:49.160 Now, the next place for us to evolve to 02:03:49.160 --> 02:03:51.270 and this is a comment I was making about 02:03:51.270 --> 02:03:53.940 the use of LiDAR for distribution, 02:03:53.940 --> 02:03:56.160 for example, on transmission 02:03:56.160 --> 02:03:58.890 we also take that a step further 02:03:58.890 --> 02:04:00.430 for the strike potential tree 02:04:00.430 --> 02:04:05.430 and start to evaluate what's the slope, how steep is it? 02:04:07.522 --> 02:04:11.670 Is the tree up slope or down slope of the transmission line? 02:04:11.670 --> 02:04:12.770 What's the proximity? 02:04:12.770 --> 02:04:16.550 And what's the path of the line of the tree? 02:04:16.550 --> 02:04:18.230 Does it have any other trees in front of it, 02:04:18.230 --> 02:04:20.430 something called the front row factor. 02:04:20.430 --> 02:04:23.180 So we can take the sheer existence of the tree 02:04:23.180 --> 02:04:25.360 and then add additional factors to determine 02:04:25.360 --> 02:04:27.950 the probability of failure. 02:04:27.950 --> 02:04:29.920 And that's what gets it to that next level 02:04:29.920 --> 02:04:31.740 of sophistication. 02:04:31.740 --> 02:04:33.215 We have that in transmission, 02:04:33.215 --> 02:04:35.400 we're not there yet for distribution 02:04:35.400 --> 02:04:36.310 and the reason we're not there 02:04:36.310 --> 02:04:38.097 is because of the sheer volume of the data 02:04:38.097 --> 02:04:40.390 that's being captured 02:04:40.390 --> 02:04:45.180 and the tree canopy, the overhang that exists 02:04:45.180 --> 02:04:46.770 are things that have to be addressed, 02:04:46.770 --> 02:04:48.900 which is why we're addressing them proactively 02:04:48.900 --> 02:04:52.440 as part of our enhanced vegetation management program 02:04:52.440 --> 02:04:55.170 that goes beyond the regulatory requirements 02:04:55.170 --> 02:04:56.650 to be able to do exactly that. 02:04:56.650 --> 02:04:58.750 So we can get to that place Commissioner 02:04:58.750 --> 02:04:59.710 that you're articulating. 02:04:59.710 --> 02:05:02.742 So we go from just the sheer fact that it exists 02:05:02.742 --> 02:05:06.690 now also calculating the probability of failure 02:05:06.690 --> 02:05:08.260 on a tree by tree basis. 02:05:08.260 --> 02:05:10.210 'Cause that's really where we wanna go. 02:05:12.070 --> 02:05:15.010 When do you imagine you would be able to do that 02:05:15.010 --> 02:05:16.643 for the distribution system? 02:05:18.290 --> 02:05:21.450 Well, we're working through that. 02:05:21.450 --> 02:05:24.590 I think it's a couple of year effort 02:05:24.590 --> 02:05:27.100 and the reason why I say that 02:05:27.100 --> 02:05:31.000 is because we're gonna have the ability 02:05:31.000 --> 02:05:34.110 to be able to do this on a portion of our system 02:05:34.110 --> 02:05:35.550 as compared to the entire system 02:05:35.550 --> 02:05:38.450 because until we do that base level work 02:05:38.450 --> 02:05:41.340 to be able to inventory all of the strike potential trees 02:05:41.340 --> 02:05:43.760 with enhanced vegetation management, remove that overhang 02:05:43.760 --> 02:05:46.950 because those are key foundational steps and elements 02:05:46.950 --> 02:05:49.910 to be able to get further accurate data, 02:05:49.910 --> 02:05:52.530 to be able to start getting angles of slopes 02:05:52.530 --> 02:05:54.240 coming from LiDAR, 02:05:54.240 --> 02:05:56.150 looking at the front row factors. 02:05:56.150 --> 02:05:57.730 And those are some of the things 02:05:57.730 --> 02:06:00.667 that we have in transmission just by the sheer virtue 02:06:00.667 --> 02:06:02.420 of the lower density of trees. 02:06:02.420 --> 02:06:04.560 So it's a multi-year effort 02:06:04.560 --> 02:06:05.770 from our perspective, Commissioner 02:06:05.770 --> 02:06:08.700 but that's exactly where we're headed with all of this 02:06:08.700 --> 02:06:10.930 because ultimately we're managing 02:06:10.930 --> 02:06:12.660 and Scott will tell you this, billions 02:06:12.660 --> 02:06:17.660 if not more of pieces of data around hourly weather forecast 02:06:18.090 --> 02:06:21.750 over 30 years, 5.3 million trees. 02:06:21.750 --> 02:06:24.070 So the only way we're doing this and a lot of this 02:06:24.070 --> 02:06:26.370 is through AI and machine learning capabilities 02:06:26.370 --> 02:06:31.370 but we have to be able to get that remote sensing capability 02:06:31.400 --> 02:06:33.530 to a far enough advancement 02:06:33.530 --> 02:06:35.800 for accurate data capture purposes. 02:06:35.800 --> 02:06:36.943 And that's some of the work that we have to do 02:06:36.943 --> 02:06:40.390 to be able to remove some of this vegetation 02:06:40.390 --> 02:06:42.993 that's in and around our overhead lines. 02:06:44.690 --> 02:06:46.130 I'd like to stop us there 02:06:46.130 --> 02:06:47.790 and I apologize for interrupting 02:06:47.790 --> 02:06:51.070 because this has been some very, very valuable information. 02:06:51.070 --> 02:06:53.353 And thanks for carrying us to those points. 02:06:54.530 --> 02:06:56.390 Thank you, Scott, for your presentation. 02:06:56.390 --> 02:06:59.580 I think we need to move next to Jake Zigelman 02:06:59.580 --> 02:07:02.353 and hear more about the customer impacts. 02:07:06.340 --> 02:07:07.930 Okay. Good morning, everyone. 02:07:07.930 --> 02:07:10.163 Mic check, can you hear me? 02:07:11.890 --> 02:07:14.180 Okay. Thanks guys. We got you dude. 02:07:14.180 --> 02:07:16.840 All right, thank you. Appreciate that. 02:07:16.840 --> 02:07:18.090 My name is Jake Zigelman 02:07:18.090 --> 02:07:22.330 and I oversee our local customer experience organization 02:07:22.330 --> 02:07:24.900 which does include a number of our customer programs 02:07:24.900 --> 02:07:27.340 related to PSPS. 02:07:27.340 --> 02:07:29.310 I know we're running a little bit late here 02:07:29.310 --> 02:07:33.600 so I will do my best to keep this section relatively brief 02:07:34.670 --> 02:07:37.980 because our overall plan is to incorporate 02:07:37.980 --> 02:07:41.740 these proposed conditions into our customer education 02:07:41.740 --> 02:07:43.410 and outreach campaigns 02:07:43.410 --> 02:07:46.200 and where appropriate continue to refine and augment 02:07:46.200 --> 02:07:48.560 our customer support offerings 02:07:48.560 --> 02:07:52.010 related to the proposed conditions from the Federal Court. 02:07:52.010 --> 02:07:57.010 So this slide shows a number of the many different 02:07:57.200 --> 02:08:00.010 menus and channels that we already use to communicate 02:08:00.010 --> 02:08:03.363 with our customers, our agency partners and our communities. 02:08:04.450 --> 02:08:06.720 Again, our plan is to incorporate the messages 02:08:06.720 --> 02:08:09.423 you're hearing today into all of these forums. 02:08:10.420 --> 02:08:12.980 It's important to note that that most of the customers 02:08:12.980 --> 02:08:16.100 agencies and tribes who would have been impacted 02:08:16.100 --> 02:08:17.837 by these proposed conditions 02:08:17.837 --> 02:08:21.390 in that 10 year historical analysis that looked back 02:08:21.390 --> 02:08:23.580 that Scott was talking about, 02:08:23.580 --> 02:08:25.920 those are primarily the same customers 02:08:25.920 --> 02:08:28.670 that we would be communicating with early and often 02:08:28.670 --> 02:08:31.377 to help raise awareness and share support services 02:08:31.377 --> 02:08:35.640 and resources under the previous conditions 02:08:35.640 --> 02:08:37.920 or the previous scope and criteria. 02:08:37.920 --> 02:08:41.490 So while these outreach programs are already in place, 02:08:41.490 --> 02:08:43.450 they do give us a number of opportunities 02:08:43.450 --> 02:08:46.880 to share this new information through a variety of channels, 02:08:46.880 --> 02:08:48.153 which you can see here. 02:08:49.665 --> 02:08:53.340 So just to touch on a few for customers, you know 02:08:53.340 --> 02:08:56.010 these are our community wildfire webinars 02:08:56.010 --> 02:08:59.450 our Statewide access and functional needs council meetings, 02:08:59.450 --> 02:09:00.590 social media channels, 02:09:00.590 --> 02:09:03.550 things of that nature for our agency and tribes, 02:09:03.550 --> 02:09:06.110 we have our regular regional working groups, 02:09:06.110 --> 02:09:09.390 our coordination meetings with emergency managers 02:09:09.390 --> 02:09:11.960 and of course, a number of one-on-one meetings 02:09:11.960 --> 02:09:14.270 with cities, counties, tribal governments 02:09:14.270 --> 02:09:17.140 and critical customer groups. 02:09:17.140 --> 02:09:20.630 And in fact, on that last point later this afternoon, 02:09:20.630 --> 02:09:24.230 we'll be hosting a meeting focused on resiliency and PSPS 02:09:24.230 --> 02:09:26.237 with our telecommunications partners, 02:09:26.237 --> 02:09:30.000 where we will be highlighting some of the same content 02:09:30.000 --> 02:09:32.483 that's gonna be discussed here today. 02:09:33.640 --> 02:09:35.913 So you can go to the next slide, please. 02:09:38.710 --> 02:09:40.000 Okay. Thank you. 02:09:40.000 --> 02:09:42.050 So this slide shows the customer programs 02:09:42.050 --> 02:09:44.220 that we have available to support customers 02:09:44.220 --> 02:09:46.481 impacted by PSPS events. 02:09:46.481 --> 02:09:51.159 Again, more than more than 90% of our 5.4 million customers 02:09:51.159 --> 02:09:53.810 don't live in the areas that are a focus 02:09:53.810 --> 02:09:55.712 of our overall PSPS program 02:09:55.712 --> 02:09:58.390 and are less likely to be impacted 02:09:58.390 --> 02:10:01.310 by these additional proposed conditions. 02:10:01.310 --> 02:10:02.870 That means that our support programs 02:10:02.870 --> 02:10:06.173 were really already focused on the customers that were 02:10:06.173 --> 02:10:09.595 and will continue to be or will likely continue to be 02:10:09.595 --> 02:10:13.040 most impacted by PSPS events. 02:10:13.040 --> 02:10:15.820 For many of our programs, like our partnerships 02:10:15.820 --> 02:10:19.320 with community-based organizations and local food banks, 02:10:19.320 --> 02:10:21.334 we're working to partner with additional organizations 02:10:21.334 --> 02:10:25.230 in those areas that are most likely to be impacted. 02:10:25.230 --> 02:10:27.110 And we're also preparing our resources 02:10:27.110 --> 02:10:29.750 to potentially handle the increased event frequency 02:10:29.750 --> 02:10:31.967 that Scott referenced earlier. 02:10:31.967 --> 02:10:36.620 Most notably with respect to these proposed conditions 02:10:36.620 --> 02:10:38.380 where we're preparing to mobilize 02:10:38.380 --> 02:10:41.080 our community resource centers more frequently 02:10:41.080 --> 02:10:42.810 and we're working with our CBO partners 02:10:42.810 --> 02:10:45.630 to prepare for the possible need to support 02:10:45.630 --> 02:10:48.540 additional customers and events. 02:10:48.540 --> 02:10:50.119 We're also in the process of assessing 02:10:50.119 --> 02:10:53.574 if the proposed conditions create additional, 02:10:53.574 --> 02:10:56.578 I'd call it small geographical pockets 02:10:56.578 --> 02:11:01.578 that might benefit from a CRC location being located nearby. 02:11:01.602 --> 02:11:04.040 And we'll continue to coordinate those potential 02:11:04.040 --> 02:11:07.070 CRC locations with our county and tribal partners 02:11:07.070 --> 02:11:11.090 which we've been doing for the last couple of years. 02:11:11.090 --> 02:11:14.870 So our overall focus remains on supporting 02:11:14.870 --> 02:11:17.415 our most vulnerable and frequently impacted customers. 02:11:17.415 --> 02:11:20.730 We'll continue to refine those strategies 02:11:20.730 --> 02:11:24.060 as we understand more regarding the actual implementation 02:11:24.060 --> 02:11:25.763 of the proposed conditions. 02:11:26.920 --> 02:11:28.592 And that is all I had. 02:11:28.592 --> 02:11:30.493 So I will pause there. 02:11:34.040 --> 02:11:34.873 Thank you, Jake. 02:11:34.873 --> 02:11:36.760 Commissioners, did you have any questions? 02:11:39.910 --> 02:11:42.523 I do Joyce, if I may. 02:11:44.580 --> 02:11:46.010 Thanks Jake. 02:11:46.010 --> 02:11:50.720 I was wondering, it's a question we frequently ask you all. 02:11:50.720 --> 02:11:52.971 And that's your portable batteries, 02:11:52.971 --> 02:11:57.971 is that 11,500 more than the count we've been given lately? 02:11:59.670 --> 02:12:03.541 I mean, I remember in one of the estimates, 02:12:03.541 --> 02:12:07.090 you all were counting when you included medical baseline 02:12:07.090 --> 02:12:12.090 and all of the critical needs 02:12:13.410 --> 02:12:16.370 that it was up to almost 20,000, I thought? 02:12:16.370 --> 02:12:18.330 But maybe my memory is wrong on that. 02:12:18.330 --> 02:12:23.183 So I just wanna know in the big a universe of the batteries 02:12:23.183 --> 02:12:27.940 that right now are needed, let alone those... 02:12:27.940 --> 02:12:32.940 Yeah, is this an add on to what's currently needed? 02:12:33.640 --> 02:12:34.473 Good question. 02:12:34.473 --> 02:12:36.430 Thank you for the question, President Batjer 02:12:38.460 --> 02:12:41.530 No, this is the same number that we have been planning 02:12:41.530 --> 02:12:42.760 to deploy. 02:12:42.760 --> 02:12:45.667 The total reflect the combination from last year 02:12:45.667 --> 02:12:48.573 and the planned deployments for this year. 02:12:49.880 --> 02:12:52.040 This program, the portable battery program, 02:12:52.040 --> 02:12:53.230 as a reminder for everyone, 02:12:53.230 --> 02:12:55.450 is targeted towards our most vulnerable 02:12:55.450 --> 02:12:57.750 and frequently impacted customers for PSPS. 02:12:57.750 --> 02:13:00.339 So these programs are, 02:13:00.339 --> 02:13:02.380 or these these batteries I should say, 02:13:02.380 --> 02:13:07.290 are deployed to our low-income medical baseline customers 02:13:07.290 --> 02:13:09.187 in either a high fire threat district 02:13:09.187 --> 02:13:13.670 or those customers who have experienced two or more 02:13:13.670 --> 02:13:15.640 PSPS events in the past. 02:13:15.640 --> 02:13:17.800 And that population of customers is around 02:13:17.800 --> 02:13:20.479 10,000 customers and change. 02:13:20.479 --> 02:13:24.720 And so the total combined battery deployments 02:13:24.720 --> 02:13:26.650 from last year and this year 02:13:26.650 --> 02:13:29.620 is going to be that roughly 11,500 02:13:29.620 --> 02:13:31.713 that you see on the screen. 02:13:33.180 --> 02:13:34.730 Does that answer your question? 02:13:38.350 --> 02:13:39.263 Yes, it does. 02:13:41.365 --> 02:13:44.244 President Batjer? 02:13:44.244 --> 02:13:46.661 (indistinct) 02:13:47.670 --> 02:13:48.503 No, you go ahead. 02:13:48.503 --> 02:13:50.762 I'm sure yours is probably richer than mine. 02:13:50.762 --> 02:13:52.860 No, it's just the follow up. 02:13:52.860 --> 02:13:54.730 How many have you deployed already, 02:13:54.730 --> 02:13:56.050 that's the first question, Jake. 02:13:56.050 --> 02:14:00.700 And the second is, if you add the additional criteria 02:14:00.700 --> 02:14:01.533 that you're targeting, 02:14:01.533 --> 02:14:06.073 what's the target number beyond 11,500? 02:14:07.550 --> 02:14:09.163 Yeah, good question. 02:14:10.070 --> 02:14:12.300 Yeah, I will start with the second part 02:14:12.300 --> 02:14:16.040 because the target remains the same at the 11,500 02:14:16.040 --> 02:14:18.560 and I'll provide a little bit more context on that 02:14:18.560 --> 02:14:19.463 in a second. 02:14:20.320 --> 02:14:25.320 We have deployed, it's around, approaching 7,000 02:14:25.780 --> 02:14:28.870 I believe is the number that we've deployed so far. 02:14:28.870 --> 02:14:31.660 So the rest are planned to be deployed 02:14:31.660 --> 02:14:32.823 for this fire season. 02:14:33.950 --> 02:14:37.320 And the additional context from the second part 02:14:37.320 --> 02:14:38.600 of your question is that 02:14:39.580 --> 02:14:41.310 and Scott touched on this a little bit earlier 02:14:41.310 --> 02:14:44.740 but based on the preliminary analysis that we've done 02:14:44.740 --> 02:14:47.173 of the impacts of this scoping criteria, 02:14:48.070 --> 02:14:53.070 the population of customers who would not have historically 02:14:54.520 --> 02:14:56.720 been impacted at all 02:14:56.720 --> 02:15:01.270 but for the new conditions proposed by the Federal Court 02:15:01.270 --> 02:15:03.000 is very, very small. 02:15:03.000 --> 02:15:04.840 It appears to be on the order 02:15:04.840 --> 02:15:07.790 of between one and one and a half percent of our customers. 02:15:08.810 --> 02:15:13.340 And so the vast majority of our customers 02:15:13.340 --> 02:15:17.070 would have already experienced a PSPS event 02:15:17.070 --> 02:15:19.750 just based on the baseline criteria. 02:15:19.750 --> 02:15:23.770 And so that would include the same population, 02:15:23.770 --> 02:15:26.160 generally speaking of vulnerable 02:15:26.160 --> 02:15:27.860 and frequently impacted customers 02:15:27.860 --> 02:15:30.771 that we were already planning to support 02:15:30.771 --> 02:15:32.377 through all of these programs 02:15:32.377 --> 02:15:34.850 and our education and outreach campaigns. 02:15:34.850 --> 02:15:38.350 And so that's why we're looking at where are those places 02:15:38.350 --> 02:15:39.750 on the margin 02:15:39.750 --> 02:15:42.510 that we might need to continue to augment things 02:15:42.510 --> 02:15:44.489 but by and large, it's the same group 02:15:44.489 --> 02:15:48.570 of vulnerable customers that we really need to work hard 02:15:48.570 --> 02:15:50.780 on educating and outreach with our partners 02:15:50.780 --> 02:15:55.780 to be prepared for a higher frequency of possible events 02:15:56.460 --> 02:15:58.310 based on this new scope and criteria. 02:15:59.620 --> 02:16:00.453 Thank you. 02:16:03.010 --> 02:16:05.870 And just to remind folks that are listening 02:16:05.870 --> 02:16:09.420 and these batteries are how much of a backup, 02:16:09.420 --> 02:16:10.823 how many hours? 02:16:13.702 --> 02:16:16.691 It varies based on their needs 02:16:16.691 --> 02:16:19.380 but it's going to be on the order of magnitude 02:16:19.380 --> 02:16:20.770 of a few hours 02:16:20.770 --> 02:16:22.660 but it really does vary based on their needs 02:16:22.660 --> 02:16:25.370 and President Batjer to your question earlier 02:16:25.370 --> 02:16:28.904 about the possibility of back-to-back events, 02:16:28.904 --> 02:16:32.498 as we engage with these vulnerable customers 02:16:32.498 --> 02:16:34.660 and go through the assessment 02:16:34.660 --> 02:16:37.560 of what's the right solution to meet their need, 02:16:37.560 --> 02:16:42.300 we typically see about 25% to a third of those customers 02:16:42.300 --> 02:16:44.060 are the folks who actually need a battery 02:16:44.060 --> 02:16:46.340 and who could benefit from a battery. 02:16:46.340 --> 02:16:48.610 Many others might need a different solution 02:16:48.610 --> 02:16:51.819 like lodging or meal replacement or something else. 02:16:51.819 --> 02:16:53.980 But as we go through that assessment, 02:16:53.980 --> 02:16:56.399 we do work with those customers 02:16:56.399 --> 02:16:59.800 to understand the possibilities of a back-to-back event. 02:16:59.800 --> 02:17:03.470 And what those would put that back to back events period 02:17:03.470 --> 02:17:05.374 would mean for them in terms of, 02:17:05.374 --> 02:17:09.060 you know, the need for medical device usage 02:17:09.060 --> 02:17:10.210 or things like that. 02:17:10.210 --> 02:17:13.054 And so, as those portable batteries are deployed, 02:17:13.054 --> 02:17:18.054 someone who who would really be disrupted 02:17:18.870 --> 02:17:21.400 by back-to-back events in a more material way 02:17:21.400 --> 02:17:23.723 might get a larger battery, for example. 02:17:24.850 --> 02:17:26.935 I really appreciate that further explanation 02:17:26.935 --> 02:17:31.250 'cause it's a real concern and it's not, as I said earlier, 02:17:31.250 --> 02:17:33.227 it's not just the PSPS events, 02:17:33.227 --> 02:17:36.820 it's the electricity on, electricity off 02:17:36.820 --> 02:17:38.853 and when are they re-energized? 02:17:40.063 --> 02:17:42.690 'Cause we've had a lot of testimony from folks 02:17:42.690 --> 02:17:47.690 that correct us or correct you when they say, 02:17:47.890 --> 02:17:51.175 well, the PSPS was 48 hours 02:17:51.175 --> 02:17:56.175 and they said, well, I didn't get re-energized for 72 hours. 02:17:58.164 --> 02:18:00.760 So it's a real concern. 02:18:00.760 --> 02:18:04.320 So the full calculation of when folks 02:18:04.320 --> 02:18:08.380 are without electricity over the period of time 02:18:08.380 --> 02:18:11.700 and then the further complication 02:18:11.700 --> 02:18:14.880 of back-to-back PSPS as well. 02:18:14.880 --> 02:18:15.823 Okay, thank you. 02:18:20.180 --> 02:18:22.990 I had a question about whether PG and E 02:18:22.990 --> 02:18:25.740 will be able to identify the circuits 02:18:25.740 --> 02:18:29.810 that are in the top 70 percentile 02:18:29.810 --> 02:18:33.640 and can you speak to PG and E plans 02:18:33.640 --> 02:18:36.940 to communicate those to public safety partners 02:18:36.940 --> 02:18:39.173 and local and tribal government? 02:18:41.250 --> 02:18:42.520 Yes, thank you for the question. 02:18:42.520 --> 02:18:45.770 The team, we do have those circuits identified. 02:18:45.770 --> 02:18:48.460 What we're in the process of doing right now 02:18:48.460 --> 02:18:50.940 is really translating that data down 02:18:50.940 --> 02:18:52.250 to a more granular level 02:18:52.250 --> 02:18:54.850 to better understand the specific customer impacts 02:18:54.850 --> 02:18:56.298 to your point around 02:18:56.298 --> 02:19:00.180 who are the potentially increment incrementally 02:19:00.180 --> 02:19:03.303 impacted customers who might be a critical facility? 02:19:04.600 --> 02:19:07.680 So we're in the process of distilling that data down 02:19:07.680 --> 02:19:09.300 to a more granular level. 02:19:09.300 --> 02:19:11.940 And I mentioned the Telekom meeting this afternoon 02:19:11.940 --> 02:19:14.420 over the next several weeks, we will be going out, 02:19:14.420 --> 02:19:16.390 our customer account reps will be going out 02:19:16.390 --> 02:19:19.220 and having these conversations with these customers 02:19:19.220 --> 02:19:20.765 about the possible impacts 02:19:20.765 --> 02:19:24.563 of this additional proposed criteria. 02:19:28.450 --> 02:19:29.370 Thank you. 02:19:29.370 --> 02:19:31.293 Were there any other questions 02:19:31.293 --> 02:19:34.143 before we turn to our final speaker? 02:19:41.650 --> 02:19:43.210 I'm seeing none. 02:19:43.210 --> 02:19:44.770 Thank you, Jake for your presentation. 02:19:44.770 --> 02:19:47.423 And let's now turn to Tracy. 02:19:48.900 --> 02:19:50.440 Hello, just as a mic check. 02:19:50.440 --> 02:19:51.513 Can everyone hear me? 02:19:55.470 --> 02:19:57.000 Yes. 02:19:57.000 --> 02:19:58.660 Great. 02:19:58.660 --> 02:20:00.620 So my name is Tracy Maratukulam. 02:20:00.620 --> 02:20:04.920 I'll be covering how we plan to share the results 02:20:04.920 --> 02:20:09.920 of these proposed conditions on our 2021 PSPS season. 02:20:10.930 --> 02:20:13.697 So to aid in gauging the effectiveness 02:20:13.697 --> 02:20:17.775 of the proposed condition and our implementation of them. 02:20:17.775 --> 02:20:21.383 PG and E plans, if you can go to the next slide. 02:20:22.252 --> 02:20:26.560 PG and E will share in our postseason report 02:20:26.560 --> 02:20:30.730 an accounting of the following for any circuit segments 02:20:30.730 --> 02:20:35.730 that is holed into scope due to the proposed condition 02:20:36.290 --> 02:20:38.093 of the event overstrike criteria. 02:20:39.000 --> 02:20:42.270 This includes the number of customers impacted 02:20:42.270 --> 02:20:45.050 due to that circuit segment being pulled into scope. 02:20:45.050 --> 02:20:47.830 Similarly, the customer impact frequency 02:20:47.830 --> 02:20:51.760 and duration of the PSPS outage that they experienced 02:20:51.760 --> 02:20:53.340 over the season. 02:20:53.340 --> 02:20:55.785 And then in accounting of any damages or hazards 02:20:55.785 --> 02:20:58.942 that are found on those circuit segments 02:20:58.942 --> 02:21:01.903 that are pulled in due to that criteria. 02:21:02.870 --> 02:21:07.870 We plan to share an accounting notes these staff 02:21:08.720 --> 02:21:13.260 on the full seasons impacts of PSPS events 02:21:13.260 --> 02:21:16.930 in our post-season report which is currently being proposed 02:21:16.930 --> 02:21:20.360 and staff proposal to the things three OYR 02:21:20.360 --> 02:21:22.377 in that proceeding. 02:21:22.377 --> 02:21:24.750 We'd like to work with the Commission on 02:21:24.750 --> 02:21:27.800 if there's any other appropriate metrics 02:21:27.800 --> 02:21:32.410 that they would like to see as part of our measurement 02:21:32.410 --> 02:21:34.620 of what the impact of implementing 02:21:34.620 --> 02:21:36.273 these proposed conditions are. 02:21:40.030 --> 02:21:42.140 That is the bulk of our proposal. 02:21:42.140 --> 02:21:45.204 So I'd like to open it up to questions, if there are any 02:21:45.204 --> 02:21:47.603 on anything else that should be measured. 02:21:53.780 --> 02:21:57.730 I believe Shelby has a question to pose. 02:21:57.730 --> 02:21:59.280 Why don't you go ahead, Shelby? 02:22:03.720 --> 02:22:04.553 Thanks Joyce. 02:22:05.680 --> 02:22:08.645 We would like to see in the post event reports 02:22:08.645 --> 02:22:12.910 a comparison of how many customers were de-energized, 02:22:12.910 --> 02:22:15.623 how many customers were de-energized 02:22:16.573 --> 02:22:17.957 due to 2021 or 2020 baseline conditions. 02:22:20.270 --> 02:22:23.990 And then how many customers were de-energized specifically 02:22:23.990 --> 02:22:25.883 due to the probation condition. 02:22:28.380 --> 02:22:30.383 Excellent. That is what we're proposing 02:22:30.383 --> 02:22:32.960 for circuit segments that are pulled into scope 02:22:32.960 --> 02:22:36.523 for the proposed per that conditions to get that account. 02:22:38.500 --> 02:22:39.450 Great. Thank you. 02:22:46.150 --> 02:22:48.763 Do any of the Commissioners have any questions? 02:22:58.710 --> 02:23:01.733 And Cliff, do you have any other questions? 02:23:05.295 --> 02:23:09.570 I do not have a question on the event reporting. 02:23:09.570 --> 02:23:11.298 However, I do have a general question. 02:23:11.298 --> 02:23:13.620 I don't know if I should wait until after this 02:23:13.620 --> 02:23:14.823 or address that now? 02:23:17.540 --> 02:23:20.423 Oh please go ahead now, Chief Fuentes. 02:23:20.423 --> 02:23:23.970 Okay, so I was wondering kind of what PG and E needs doing 02:23:23.970 --> 02:23:25.940 in the emerging technology 02:23:26.880 --> 02:23:31.070 in this with you know, anticipation, fault detection, 02:23:31.070 --> 02:23:35.240 early detection, things like that. 02:23:35.240 --> 02:23:40.240 You know, it seems like that technology might be helpful 02:23:44.470 --> 02:23:45.640 for this type of risk 02:23:45.640 --> 02:23:48.080 but I don't know, I know you guys were piloting 02:23:48.080 --> 02:23:49.253 some of that technology. 02:23:49.253 --> 02:23:52.180 So I was curious what the effectiveness of that was 02:23:52.180 --> 02:23:55.340 and if looking at the WMP this year, 02:23:55.340 --> 02:23:57.540 you looked like you were deploying additional 02:23:57.540 --> 02:23:58.980 emerging technologies 02:23:58.980 --> 02:24:03.980 and are they in these areas if this proposed credence 02:24:04.055 --> 02:24:04.888 accounted for it, 02:24:04.888 --> 02:24:07.313 there's gonna be some technology that's gonna be. 02:24:10.410 --> 02:24:11.830 Yep, yeah. Chief Fuentes. 02:24:11.830 --> 02:24:13.250 Thank you for that question, 02:24:13.250 --> 02:24:15.290 this is Sumeet, I'm happy to take that. 02:24:15.290 --> 02:24:17.028 So there's a number of breakthrough 02:24:17.028 --> 02:24:21.070 and emerging technologies that we're piloting. 02:24:21.070 --> 02:24:24.210 So the one you mentioned in regards to REFCL, 02:24:24.210 --> 02:24:26.710 Rapid Earth Fault Current Limiter 02:24:26.710 --> 02:24:28.820 and it comes from Australia. 02:24:28.820 --> 02:24:32.170 I personally spent some time with the operators in Australia 02:24:32.170 --> 02:24:36.370 to understand how they're implementing that technology. 02:24:36.370 --> 02:24:40.462 And we actually have upgraded one of our circuits 02:24:40.462 --> 02:24:44.371 in the Napa Sonoma County area 02:24:44.371 --> 02:24:49.371 within the high parts but district roughly 150 miles 02:24:49.380 --> 02:24:53.522 that has the rapid earth fault current limiting capability. 02:24:53.522 --> 02:24:56.790 Now, you know, the intent of that technology 02:24:56.790 --> 02:25:01.790 is if there's a potential wires down type of a situation 02:25:03.810 --> 02:25:07.140 it puts equal and opposite energy onto the line 02:25:07.140 --> 02:25:10.890 so that it basically neutralizes the electricity flow 02:25:10.890 --> 02:25:12.180 and you don't have enough energy 02:25:12.180 --> 02:25:14.850 to create a potential fire ignition. 02:25:14.850 --> 02:25:18.660 And that's really focusing on one of three different types 02:25:18.660 --> 02:25:20.700 of faults that we see within our system. 02:25:20.700 --> 02:25:23.960 Something called a Phase to Ground Fault. 02:25:23.960 --> 02:25:27.810 One of the things that the rapid earth fault current limiter 02:25:27.810 --> 02:25:29.704 right now does not necessarily have 02:25:29.704 --> 02:25:32.230 the technology to address is something 02:25:32.230 --> 02:25:34.330 called a Phase-to-Phase Fault, 02:25:34.330 --> 02:25:37.700 which would be two different phases of a line 02:25:37.700 --> 02:25:40.280 that may come together during periods of high wind 02:25:40.280 --> 02:25:43.031 and create something called line slopping. 02:25:43.031 --> 02:25:46.530 Another element is the third category 02:25:46.530 --> 02:25:47.910 is called a high impedance fault, 02:25:47.910 --> 02:25:51.560 where you may have a tree, a branch of tree 02:25:51.560 --> 02:25:54.311 that traverses two different phases. 02:25:54.311 --> 02:25:56.950 And at the moment that technology 02:25:56.950 --> 02:25:58.800 does not mitigate those defaults 02:25:58.800 --> 02:26:01.510 but it is effective in this space. 02:26:01.510 --> 02:26:06.500 And we are in the process of evaluating 02:26:06.500 --> 02:26:09.500 the operational use cases 02:26:09.500 --> 02:26:12.010 to be able to understand the limitations 02:26:12.010 --> 02:26:14.861 and to understand where within our blueprint 02:26:14.861 --> 02:26:17.957 we can expand and implement this capability. 02:26:17.957 --> 02:26:21.410 And so that is absolutely a tool within our toolkit 02:26:21.410 --> 02:26:23.580 that we're very optimistic about. 02:26:23.580 --> 02:26:26.090 But again, it's not a silver bullet. 02:26:26.090 --> 02:26:29.280 Another technology that we actually filed a patent for 02:26:29.280 --> 02:26:32.861 we've described it within the wildfire mitigation plan, 02:26:32.861 --> 02:26:35.840 something called a DTS-Fast. 02:26:35.840 --> 02:26:39.199 It's a fast acting scheme in essence 02:26:39.199 --> 02:26:41.296 and we're piloting another transmission line. 02:26:41.296 --> 02:26:46.010 And in essence, going back to the discussion 02:26:46.010 --> 02:26:47.550 that President Batjer and I were having, 02:26:47.550 --> 02:26:48.810 one of the things we're looking to do 02:26:48.810 --> 02:26:50.370 is engineer the risk out 02:26:50.370 --> 02:26:53.430 so that for our overhead electric system 02:26:53.430 --> 02:26:57.050 if the system fails, it fails safely 02:26:57.050 --> 02:27:00.006 and has the capacity to feel safe. 02:27:00.006 --> 02:27:02.250 So what we're basically doing is in this instance 02:27:02.250 --> 02:27:06.370 we're outfitting some of our towers with laser technology. 02:27:06.370 --> 02:27:10.370 And these are lasers that are mounted on our towers 02:27:10.370 --> 02:27:13.730 no different than lasers use in self autonomous vehicles 02:27:13.730 --> 02:27:18.600 and the intent is that creates a laser field around, 02:27:18.600 --> 02:27:20.480 an invisible laser field, 02:27:20.480 --> 02:27:22.160 around our overhead conductors 02:27:22.160 --> 02:27:25.480 and if there's any breach within that laser field, 02:27:25.480 --> 02:27:28.470 that specific section of the system automatically 02:27:28.470 --> 02:27:31.420 re-energizes in less than a millisecond. 02:27:31.420 --> 02:27:34.970 It's the hardware that enables that software capabilities. 02:27:34.970 --> 02:27:36.440 So we've filed a patent for that. 02:27:36.440 --> 02:27:38.520 And actually we've proved that out 02:27:38.520 --> 02:27:41.030 from a field viability perspective 02:27:41.030 --> 02:27:43.610 and we're doing the operational assessment 02:27:43.610 --> 02:27:46.250 of that technology as well. 02:27:46.250 --> 02:27:48.960 So that's another tool within our toolkit. 02:27:48.960 --> 02:27:51.870 And then the last piece I'll share with you is that 02:27:51.870 --> 02:27:54.840 you know, obviously we're one of the first movers 02:27:54.840 --> 02:27:58.070 across the nation to implement smart meters. 02:27:58.070 --> 02:27:59.930 So one of the things we're doing is working 02:27:59.930 --> 02:28:01.820 with the smart meter service provider 02:28:01.820 --> 02:28:05.910 to be able to outfit that with additional sensors, 02:28:05.910 --> 02:28:07.580 it's called Sensor IQ 02:28:07.580 --> 02:28:10.270 that gives us the ability to be able to measure 02:28:10.270 --> 02:28:14.240 not just the traditional volume of electricity 02:28:14.240 --> 02:28:16.880 and gas being used, which is what's been in operations 02:28:16.880 --> 02:28:19.070 for more than a decade with smart meters, 02:28:19.070 --> 02:28:20.980 but also the ability to be able to detect 02:28:20.980 --> 02:28:22.940 things like partial voltage. 02:28:22.940 --> 02:28:24.340 So that if there's a wires down 02:28:24.340 --> 02:28:29.340 we have instant detection back within our control center 02:28:29.625 --> 02:28:32.710 which is staffed 24/7 365 days a year. 02:28:32.710 --> 02:28:36.070 And we can dispatch an appropriate qualified 02:28:36.070 --> 02:28:39.650 electrical worker to be able to do the remediation. 02:28:39.650 --> 02:28:43.250 So early detection is one category 02:28:43.250 --> 02:28:45.117 and then the other two fall into that category 02:28:45.117 --> 02:28:47.280 of engineering the risk out 02:28:47.280 --> 02:28:50.650 and providing additional safety margin within our system. 02:28:50.650 --> 02:28:52.960 So when it does fail, that does fail in a safe manner. 02:28:52.960 --> 02:28:56.484 So those are some of the technologies that we have teed up. 02:28:56.484 --> 02:28:58.810 And there's a whole bunch of additional ones 02:28:58.810 --> 02:29:01.150 that I didn't touch with the essence of time 02:29:01.150 --> 02:29:02.520 that we have included in the WMP. 02:29:02.520 --> 02:29:05.410 So we're pretty excited about what needs to happen 02:29:05.410 --> 02:29:08.260 and I'm very encouraged by what I'm also seeing 02:29:08.260 --> 02:29:11.330 the other IOUs in California doing 02:29:11.330 --> 02:29:14.570 and us working as the collective us 02:29:14.570 --> 02:29:17.683 to really move the needle forward in the technology space. 02:29:19.550 --> 02:29:20.530 Thank you for that. 02:29:20.530 --> 02:29:23.940 (indistinct) to hear that and look forward to hearing more 02:29:23.940 --> 02:29:26.260 about the pilots outcomes. 02:29:26.260 --> 02:29:27.340 Thanks. 02:29:27.340 --> 02:29:28.173 Our pleasure 02:29:30.900 --> 02:29:32.040 Sumeet, this is Joyce 02:29:32.040 --> 02:29:34.910 and the scope of our workshop today 02:29:34.910 --> 02:29:36.160 hasn't really touched on this 02:29:36.160 --> 02:29:40.520 but are there any other legal or regulatory solutions here 02:29:40.520 --> 02:29:42.040 where we're dealing with trees 02:29:42.040 --> 02:29:44.370 that are beyond utility easements 02:29:44.370 --> 02:29:46.760 and beyond utility rights of way? 02:29:46.760 --> 02:29:50.510 Are there other solutions that we should be looking at 02:29:50.510 --> 02:29:54.140 as far as the planting and replacement of trees 02:29:54.140 --> 02:29:56.393 that impact power line? 02:29:59.280 --> 02:30:01.027 That's a great question, Joyce 02:30:01.027 --> 02:30:04.195 and I think one of the things that... 02:30:04.195 --> 02:30:06.423 And I appreciate you opening the door on that question. 02:30:06.423 --> 02:30:08.760 I think it's probably a separate follow-up deep dive 02:30:08.760 --> 02:30:09.593 we can have. 02:30:09.593 --> 02:30:14.593 I think one of the challenges that obviously we face a times 02:30:14.916 --> 02:30:16.930 and we're very mindful, 02:30:16.930 --> 02:30:20.224 we understand the importance of trees to the climate as well 02:30:20.224 --> 02:30:23.730 but obviously as we do identify trees 02:30:23.730 --> 02:30:26.390 as part of our enhanced vegetation management program, 02:30:26.390 --> 02:30:30.760 you know, for removal because they do pose that higher risk 02:30:30.760 --> 02:30:33.530 but at times, you know, we're not aligned 02:30:33.530 --> 02:30:37.760 with the viewpoints that may exist locally, 02:30:37.760 --> 02:30:38.670 you know with our customers. 02:30:38.670 --> 02:30:40.400 And we're very, very respectful of that 02:30:40.400 --> 02:30:42.749 and insensitive to some of these trees 02:30:42.749 --> 02:30:44.420 because some of these trees at one point in time 02:30:44.420 --> 02:30:46.600 were not a threat or a risk 02:30:46.600 --> 02:30:49.617 but now given the change of condition in and around the tree 02:30:49.617 --> 02:30:52.820 and the power line has created that risk. 02:30:52.820 --> 02:30:55.200 And I think there's opportunities choice, right? 02:30:55.200 --> 02:30:57.060 Not necessarily to problem solve here 02:30:57.060 --> 02:31:00.468 but we'll be happy to engage with you in that discussion 02:31:00.468 --> 02:31:03.660 with our team on what are some of the additional 02:31:03.660 --> 02:31:06.103 legal regulatory opportunities exist 02:31:06.103 --> 02:31:10.388 to be able to do the right thing in a very prudent manner 02:31:10.388 --> 02:31:14.330 and mitigate that risk in an expeditious manner as well 02:31:14.330 --> 02:31:17.290 because there are instances where it takes us 02:31:17.290 --> 02:31:22.048 12, 18, 24 months to be able to work through the processes 02:31:22.048 --> 02:31:25.500 we have today to be able to mitigate that risk. 02:31:25.500 --> 02:31:29.110 And in those instances, when we talk about 02:31:29.110 --> 02:31:32.960 some of these higher priority trees and higher risk trees 02:31:32.960 --> 02:31:35.632 and now obviously that has an adverse impact 02:31:35.632 --> 02:31:38.730 on when a potential PSPS may be called. 02:31:38.730 --> 02:31:42.040 So there is an interdependency there, Joyce 02:31:42.040 --> 02:31:44.030 I don't think it's a silver bullet 02:31:44.030 --> 02:31:46.980 but there's absolutely an opportunity, I think 02:31:46.980 --> 02:31:51.140 across the board and working on multi jurisdiction areas 02:31:51.140 --> 02:31:56.140 of between the local government, the respective CPUC 02:31:56.429 --> 02:31:59.640 to be able to help establish some mechanism 02:31:59.640 --> 02:32:03.110 by which we can streamline some of the risk reduction work 02:32:03.110 --> 02:32:05.031 that all the IOUs are doing not just PG and E 02:32:05.031 --> 02:32:06.581 within the state of California. 02:32:10.830 --> 02:32:13.457 Well, thank you very much for PG and E presentations. 02:32:13.457 --> 02:32:17.500 Unless there's any other questions from Commissioners, 02:32:17.500 --> 02:32:20.440 I see Commissioner Shiroma would like to pose the question. 02:32:20.440 --> 02:32:21.590 Go ahead, Commissioner. 02:32:29.230 --> 02:32:32.713 So we are unable to hear you Commissioner Shiroma. 02:32:49.877 --> 02:32:54.127 Do you wanna type in your question, Commissioner? 02:33:12.620 --> 02:33:15.540 Immediately after the Commissioner's question, 02:33:15.540 --> 02:33:19.853 we'll likely be moving into the public comment mode. 02:33:20.700 --> 02:33:25.570 So I would say that that's what's going to happen next 02:33:26.470 --> 02:33:28.170 after the Commissioner's question. 02:33:42.250 --> 02:33:43.830 So the question is, 02:33:43.830 --> 02:33:47.440 are you poised to update your PSPS portal 02:33:47.440 --> 02:33:50.093 should the additional criteria be approved? 02:33:51.010 --> 02:33:52.220 Absolutely. 02:33:52.220 --> 02:33:53.870 We've gotten a lot of feedback, 02:33:53.870 --> 02:33:56.560 you know, Commissioner, as part of our listing sessions 02:33:56.560 --> 02:34:01.440 that we've done both with the local agencies 02:34:01.440 --> 02:34:03.850 as well as with their emergency managers 02:34:03.850 --> 02:34:06.120 as well as at the state level 02:34:06.120 --> 02:34:09.250 with both the respected Calloways and Cal FIRE 02:34:09.250 --> 02:34:12.300 and our intent is absolutely you have to continue 02:34:12.300 --> 02:34:14.293 to make improvements on our PSPS portal 02:34:14.293 --> 02:34:18.700 so that we're able to provide timely information 02:34:18.700 --> 02:34:23.490 that's relevant to the local community and make it clear 02:34:23.490 --> 02:34:27.010 as changes happen to that information, 02:34:27.010 --> 02:34:29.900 given the changes in the weather scenario 02:34:29.900 --> 02:34:31.698 that we make it very clear 02:34:31.698 --> 02:34:35.010 for all of the interested stakeholders 02:34:35.010 --> 02:34:39.410 and impacted stakeholders on the situational awareness. 02:34:39.410 --> 02:34:41.204 So that's absolutely something that we're committed to. 02:34:41.204 --> 02:34:43.530 I know we've got Erin Johnson, 02:34:43.530 --> 02:34:46.079 who's leading that effort up from our side 02:34:46.079 --> 02:34:46.912 on the call as well. 02:34:46.912 --> 02:34:49.462 And I don't know if Erin will add anything to that? 02:34:56.880 --> 02:34:59.520 No, I think you've covered it well, Sumeet 02:34:59.520 --> 02:35:02.730 the only thing I would add is, 02:35:02.730 --> 02:35:04.858 that as we begin our outreach 02:35:04.858 --> 02:35:07.570 that starts a week from today 02:35:07.570 --> 02:35:12.390 in Santa Clara County with counties and tribes, 02:35:12.390 --> 02:35:16.730 we will be sharing enhanced information about the locations 02:35:16.730 --> 02:35:19.740 and the frequency of these potential criteria 02:35:19.740 --> 02:35:21.260 even though they are not yet final. 02:35:21.260 --> 02:35:25.380 And we started previewing that with counties and tribes 02:35:25.380 --> 02:35:27.079 over the last couple of weeks 02:35:27.079 --> 02:35:30.140 as there was more and more local discussion 02:35:30.140 --> 02:35:31.510 and these matters have been covered 02:35:31.510 --> 02:35:33.560 in the newspapers and we're raising to awareness. 02:35:33.560 --> 02:35:36.070 We were hoping to have a little more certainty 02:35:36.070 --> 02:35:39.250 for those jurisdictions before we started speaking 02:35:39.250 --> 02:35:40.083 about those issues 02:35:40.083 --> 02:35:42.700 but we were getting questions from a few of them, 02:35:42.700 --> 02:35:44.420 so we have proactively reached out 02:35:44.420 --> 02:35:45.950 to all counties and tribes to make sure 02:35:45.950 --> 02:35:47.880 they're aware of these potential developments. 02:35:47.880 --> 02:35:50.930 And we'll certainly let them know as they finalize 02:35:50.930 --> 02:35:54.770 and be incorporating the impacts of that into all the tools 02:35:54.770 --> 02:35:55.870 that we're developing. 02:35:57.310 --> 02:35:58.143 Thank you. 02:36:00.100 --> 02:36:02.350 Thank you, Erin. 02:36:02.350 --> 02:36:03.300 Joyce, back to you. 02:36:05.553 --> 02:36:07.410 Thank you. Thank you. 02:36:07.410 --> 02:36:11.500 We'll now move on to the public comment portion 02:36:11.500 --> 02:36:12.430 of the proceedings, 02:36:12.430 --> 02:36:14.973 so I will turn it over to the operator. 02:36:17.180 --> 02:36:18.073 Thank you. 02:36:19.120 --> 02:36:21.500 The first public comment on the line 02:36:21.500 --> 02:36:26.160 is coming from Katherine Sandoval. 02:36:26.160 --> 02:36:27.550 Please state your organization. 02:36:27.550 --> 02:36:28.523 Your line is open. 02:36:29.900 --> 02:36:30.880 Yes. Thank you. 02:36:30.880 --> 02:36:33.070 This is professor and former Commissioner, 02:36:33.070 --> 02:36:34.190 Katherine Sandoval. 02:36:34.190 --> 02:36:37.700 I'm the director of the Insurance law Institute 02:36:37.700 --> 02:36:39.640 at Santa Clara University. 02:36:39.640 --> 02:36:40.473 Can you hear me? 02:36:42.550 --> 02:36:43.383 Yes. 02:36:44.780 --> 02:36:47.350 So I wanted to make a couple of comments. 02:36:47.350 --> 02:36:50.270 First of all, thank you so much for having this workshop. 02:36:50.270 --> 02:36:51.983 It's been very informative. 02:36:52.950 --> 02:36:56.410 One question I think that we haven't asked is that 02:36:56.410 --> 02:37:01.410 when you apply the PG and E's model to years prior to 2018 02:37:01.910 --> 02:37:03.510 it raises the question of really 02:37:03.510 --> 02:37:05.260 how predictive those models are 02:37:05.260 --> 02:37:08.370 since the vegetation management criteria 02:37:08.370 --> 02:37:10.569 and wildfire mitigation requirements 02:37:10.569 --> 02:37:14.550 changed dramatically after 2018. 02:37:14.550 --> 02:37:18.528 And so thus my question is really whether or not the data 02:37:18.528 --> 02:37:22.480 where the model indicates 2019 and 2020 data 02:37:22.480 --> 02:37:24.309 really are the best predictors of the impact 02:37:24.309 --> 02:37:27.630 of potential PSPS on the application 02:37:27.630 --> 02:37:29.731 of probation conditions, 11 and 12 02:37:29.731 --> 02:37:33.050 and where we see for example, in 2018, 2020, 02:37:33.050 --> 02:37:35.443 no additional PSPS? 02:37:35.443 --> 02:37:38.750 I would also emphasize that PG and E was saying that 02:37:38.750 --> 02:37:43.330 this would affect 1% to 1.5% more customers 02:37:43.330 --> 02:37:47.421 and they didn't provide the detailed County by County data 02:37:47.421 --> 02:37:49.660 in this analysis. 02:37:49.660 --> 02:37:51.140 But as stated previously, 02:37:51.140 --> 02:37:53.460 the court can also order PG and E 02:37:53.460 --> 02:37:55.430 to provide more power backup 02:37:55.430 --> 02:37:59.960 and other appropriate resources in the affected areas. 02:37:59.960 --> 02:38:02.860 So what really this indicates is that 02:38:02.860 --> 02:38:05.420 we need to think about two different things. 02:38:05.420 --> 02:38:08.490 One, whether or not, if in fact there were 02:38:08.490 --> 02:38:11.350 unaddressed tree overstrikes 02:38:12.540 --> 02:38:16.730 and overhanging vegetation that hit the line, 02:38:16.730 --> 02:38:18.340 whether that would, for example, 02:38:18.340 --> 02:38:22.683 violate California Public Utilities Code 451 02:38:22.683 --> 02:38:27.000 indicating that PG and E is not operating safely. 02:38:27.000 --> 02:38:30.860 So the judge is trying to address this risk 02:38:30.860 --> 02:38:32.457 and unaddressed risks 02:38:32.457 --> 02:38:34.530 and for example, what caused the Zogg fire 02:38:34.530 --> 02:38:36.363 through these probation conditions? 02:38:37.290 --> 02:38:39.620 So the Insurance Law Institute 02:38:39.620 --> 02:38:41.768 of California at Santa Clara University believes that 02:38:41.768 --> 02:38:46.768 these probation conditions are well calculated 02:38:46.920 --> 02:38:48.960 to protect public safety. 02:38:48.960 --> 02:38:52.010 And Commissioners I would urge you to support 02:38:52.010 --> 02:38:54.950 these probation conditions, if you can make comments 02:38:54.950 --> 02:38:58.820 to the court suggesting any appropriate modifications 02:38:58.820 --> 02:39:00.330 to the probation conditions, 02:39:00.330 --> 02:39:03.340 such as the addition of requirement to PG and E 02:39:03.340 --> 02:39:04.510 provide power backup 02:39:04.510 --> 02:39:06.561 and other resources to effective customers. 02:39:06.561 --> 02:39:09.110 And what's really important 02:39:09.110 --> 02:39:11.790 and what these probation conditions are trying to achieve 02:39:11.790 --> 02:39:13.768 is the same thing that the Commission is trying to achieve, 02:39:13.768 --> 02:39:18.768 which is to save lives, save lungs, safeguard property 02:39:19.720 --> 02:39:20.910 and the environment 02:39:20.910 --> 02:39:24.420 and also forestal climate change for more wildfires. 02:39:24.420 --> 02:39:26.410 So thank you very much for this workshop 02:39:26.410 --> 02:39:29.930 and I encourage your support for these probation conditions. 02:39:29.930 --> 02:39:30.763 Thank you. 02:39:34.510 --> 02:39:35.920 Thank you, our next public comment 02:39:35.920 --> 02:39:37.824 comes from Richard Scaff. 02:39:37.824 --> 02:39:38.810 Please state your organization. 02:39:38.810 --> 02:39:39.710 Your line is open. 02:39:42.200 --> 02:39:43.700 My name is Richard Skaff. 02:39:43.700 --> 02:39:47.220 I am the Executive Director of a nonprofit organization 02:39:47.220 --> 02:39:49.550 called Designing Accessible Communities. 02:39:49.550 --> 02:39:50.750 Are you able to hear me? 02:39:53.540 --> 02:39:54.373 Hello. 02:39:55.827 --> 02:39:58.071 You go ahead, Mr. Skaff. 02:39:58.071 --> 02:40:00.119 We can hear you, go ahead. 02:40:00.119 --> 02:40:03.000 Okay. Thank you. 02:40:03.000 --> 02:40:06.040 A number of things first, PG and E 02:40:06.040 --> 02:40:08.053 is only listening to those, 02:40:09.380 --> 02:40:13.612 the groups that had described during his presentation today 02:40:13.612 --> 02:40:17.490 that agree with its inadequate mitigation measures. 02:40:17.490 --> 02:40:19.710 And I say that because as the director 02:40:19.710 --> 02:40:23.740 of a nonprofit organization who deals with the rights 02:40:23.740 --> 02:40:26.490 of people with disabilities and the protection of those 02:40:28.000 --> 02:40:31.850 those folks in communities throughout the state 02:40:33.160 --> 02:40:38.160 that are affected by this condition that was created 02:40:38.460 --> 02:40:41.940 by the three electric utilities, 02:40:41.940 --> 02:40:43.230 they have made it clear 02:40:43.230 --> 02:40:45.666 that they don't wanna hear anything 02:40:45.666 --> 02:40:49.340 unless it is in support of what they propose 02:40:49.340 --> 02:40:50.910 and what they're doing. 02:40:50.910 --> 02:40:55.730 Not all right that should be on the medical baseline 02:40:55.730 --> 02:40:57.570 have joined that program. 02:40:57.570 --> 02:41:00.500 I know that PG and E has made some effort 02:41:00.500 --> 02:41:05.360 to educate their rate payers about the program 02:41:05.360 --> 02:41:09.390 but it still has not been successful 02:41:09.390 --> 02:41:12.200 in getting all that should be in that program, 02:41:12.200 --> 02:41:13.223 into the program. 02:41:14.059 --> 02:41:18.773 And to date, there is inadequate. 02:41:20.090 --> 02:41:22.493 There's a lack of adequate mitigation measures. 02:41:23.420 --> 02:41:27.160 Presently, one of the major mitigation measures 02:41:27.160 --> 02:41:32.160 that they have touted the Yeti 3000 battery generators 02:41:33.600 --> 02:41:37.840 that have been distributed by the California Foundation 02:41:37.840 --> 02:41:39.120 for Independent Living Centers. 02:41:39.120 --> 02:41:41.783 They've got a $5 million grant from PG and E. 02:41:43.409 --> 02:41:48.409 They are the least supported battery generator 02:41:50.660 --> 02:41:53.730 of all of those that are available today. 02:41:53.730 --> 02:41:56.290 One of their major issues is that , 02:41:56.290 --> 02:42:00.483 of all of the most visible 02:42:00.483 --> 02:42:05.483 and major battery generators available, 02:42:06.830 --> 02:42:11.350 this one only is able to have 500 recharging capabilities. 02:42:11.350 --> 02:42:15.580 That's when it gets the power within the battery reduced, 02:42:15.580 --> 02:42:17.620 it is recharged. 02:42:17.620 --> 02:42:22.620 It can only have 500 recharges when most battery generators 02:42:23.280 --> 02:42:27.370 that are produced for the type of mitigation 02:42:27.370 --> 02:42:30.410 that we're talking about can be recharged 02:42:30.410 --> 02:42:34.260 between 1500 and 2500 times, 02:42:34.260 --> 02:42:35.960 a substantial difference. 02:42:35.960 --> 02:42:40.960 I don't know why PG and E and the California Foundation 02:42:41.160 --> 02:42:44.100 for Independent Living centers decided on that one. 02:42:44.100 --> 02:42:46.185 There was no discussion with anybody 02:42:46.185 --> 02:42:51.185 other than the two organizations, PG and E and CFILC. 02:42:52.470 --> 02:42:53.720 And that's another issue. 02:42:54.580 --> 02:42:57.120 During that first development, 02:42:57.120 --> 02:43:02.120 there was a meeting created between PG and E and CFILC. 02:43:02.800 --> 02:43:05.363 No one else was included in that meeting. 02:43:06.410 --> 02:43:11.410 And I have a number of other issues I'd like to speak to. 02:43:11.850 --> 02:43:13.959 We don't have transportation for people 02:43:13.959 --> 02:43:16.550 that don't have their own transportation 02:43:16.550 --> 02:43:21.210 to get to the charging stations that PG and E opens 02:43:21.210 --> 02:43:23.303 so that we can recharge equipment. 02:43:25.720 --> 02:43:28.230 Most of the counties, including Sonoma, 02:43:28.230 --> 02:43:31.750 I'm talking to them next month about this 02:43:31.750 --> 02:43:33.860 don't provide transportation 02:43:33.860 --> 02:43:36.930 and unlike Southern California Edison 02:43:36.930 --> 02:43:39.220 in a report that I just read 02:43:39.220 --> 02:43:43.480 apparently they are providing vehicles. 02:43:43.480 --> 02:43:48.480 They have vans that either bring equipment to a person 02:43:48.840 --> 02:43:50.190 who is home bound 02:43:50.190 --> 02:43:55.190 or they take a person in a wheelchair accessible vehicle 02:43:59.780 --> 02:44:01.483 to the charging stations. 02:44:02.550 --> 02:44:04.972 That is not happening throughout the state 02:44:04.972 --> 02:44:09.593 and especially in the PG and E grid locations. 02:44:11.610 --> 02:44:16.610 So I would ask the Commission to consider the need 02:44:17.710 --> 02:44:22.710 to require PG and E to have input from those of us 02:44:24.030 --> 02:44:26.780 that don't necessarily agree with what they're doing 02:44:26.780 --> 02:44:28.370 as far as mitigation. 02:44:28.370 --> 02:44:32.190 I would ask the Commission to consider requiring all 02:44:32.190 --> 02:44:34.770 of the electric utilities they'll receive 02:44:34.770 --> 02:44:36.697 during the energization events 02:44:36.697 --> 02:44:41.601 providing wheelchair accessible transportation 02:44:41.601 --> 02:44:46.601 to charging stations and hotels in Sonoma County, 02:44:46.880 --> 02:44:50.700 for example, there are no accessible cabs 02:44:50.700 --> 02:44:54.670 even though the County oversees and gives permits for cabs. 02:44:54.670 --> 02:44:56.940 There are no wheelchair accessible cabs. 02:44:56.940 --> 02:44:59.317 So there is virtually no wheelchair accessible 02:44:59.317 --> 02:45:03.900 transportation available for immediate transportation 02:45:03.900 --> 02:45:07.060 to either the charging stations or to a hotel 02:45:07.060 --> 02:45:08.513 or to go pick up food. 02:45:09.370 --> 02:45:13.510 And lastly, we need mitigation measures 02:45:13.510 --> 02:45:16.800 that are going to be able to handle 02:45:18.050 --> 02:45:22.080 running a refrigerator for 24 hours or 48 hours. 02:45:22.080 --> 02:45:24.560 The Yeti 3000 will not do that. 02:45:24.560 --> 02:45:27.670 In fact, when I picked the one I have up 02:45:27.670 --> 02:45:31.500 from the local independent living center, I asked, 02:45:31.500 --> 02:45:34.290 what happens if I need to run my refrigerator 02:45:34.290 --> 02:45:35.123 during this time? 02:45:35.123 --> 02:45:38.290 And they said, Oh, don't plug the refrigerator in 02:45:38.290 --> 02:45:41.700 because it will reduce the power so quickly 02:45:41.700 --> 02:45:45.560 that you won't have adequate power for the rest 02:45:45.560 --> 02:45:49.430 of the period of the de-energization event. 02:45:49.430 --> 02:45:54.430 So there are some substantial mitigation measures 02:45:54.830 --> 02:45:56.423 that are still lacking. 02:45:58.371 --> 02:46:01.470 And we as a community of vulnerable seniors 02:46:01.470 --> 02:46:02.720 and people with disabilities 02:46:02.720 --> 02:46:06.270 are still being put in jeopardy 02:46:06.270 --> 02:46:09.200 because of this lack of mitigation. 02:46:09.200 --> 02:46:13.810 And last I would ask that you ask the electric utilities 02:46:13.810 --> 02:46:18.810 whether we as representatives of the communities we serve, 02:46:19.900 --> 02:46:21.300 agree or don't agree, 02:46:21.300 --> 02:46:24.233 we should be part of that process of discussion. 02:46:25.680 --> 02:46:26.610 So thank you very much 02:46:26.610 --> 02:46:29.030 for allowing me to speak completely today. 02:46:29.030 --> 02:46:30.253 I appreciate the time. 02:46:35.420 --> 02:46:37.780 Our next public comment comes from Will Abrams. 02:46:37.780 --> 02:46:39.160 Your line is open. 02:46:39.160 --> 02:46:41.246 Please state your organization. 02:46:41.246 --> 02:46:43.236 Thanks very much. 02:46:43.236 --> 02:46:44.620 Good morning Commissioners 02:46:44.620 --> 02:46:47.990 and thank you for holding this important proceeding. 02:46:47.990 --> 02:46:51.500 The presentations here today seemed perfectly plausible. 02:46:51.500 --> 02:46:54.480 If you don't consider prior comments from PG and E. 02:46:54.480 --> 02:46:57.730 In 2019 PG and E relied and parsed out 02:46:57.730 --> 02:46:58.990 substantial compliance 02:46:58.990 --> 02:47:02.110 from actual vegetation management compliance. 02:47:02.110 --> 02:47:05.470 In 2020 they excluded clauses of recent fires 02:47:05.470 --> 02:47:10.090 from their fire protection index but rely on it here today. 02:47:10.090 --> 02:47:14.490 Now in 2021, PG and E misappropriates the black Swan term 02:47:14.490 --> 02:47:16.610 to explain away failures. 02:47:16.610 --> 02:47:19.740 No a black Swan is not a low probability 02:47:19.740 --> 02:47:21.960 but high consequence event. 02:47:21.960 --> 02:47:22.860 This is wrong. 02:47:22.860 --> 02:47:25.840 Black swans are only unpredictable events 02:47:25.840 --> 02:47:28.730 PG and E is taking fires like Kincade and Zogg 02:47:28.730 --> 02:47:30.360 and calling them black swans 02:47:30.360 --> 02:47:34.310 to avoid accountability and liability. 02:47:34.310 --> 02:47:36.316 PG and E changes the goalposts every time 02:47:36.316 --> 02:47:40.080 there are failures detected by a court or this Commission. 02:47:40.080 --> 02:47:43.900 In one hour, PG and E is being arraigned about 10 minutes 02:47:43.900 --> 02:47:45.100 from my burned down house 02:47:45.100 --> 02:47:47.410 and where I have evacuated three other times 02:47:47.410 --> 02:47:49.130 due to PG and E fires. 02:47:49.130 --> 02:47:52.290 And I expect a similar range of excuses will be leveraged 02:47:52.290 --> 02:47:53.810 in that proceeding. 02:47:53.810 --> 02:47:57.420 If the Commission or Judge Alsup or interveners like me, 02:47:57.420 --> 02:47:59.330 micromanage PG and E, 02:47:59.330 --> 02:48:01.807 I believe we are in a lose lose situation. 02:48:01.807 --> 02:48:04.820 Let PG and E call it substantial compliance 02:48:04.820 --> 02:48:08.060 or a black Swan or Turkey on Thanksgiving, 02:48:08.060 --> 02:48:10.650 the Commission shouldn't care or try to parse out 02:48:10.650 --> 02:48:13.310 fact from fiction and PG and E statements. 02:48:13.310 --> 02:48:18.290 Results, results, results, nothing else matters. 02:48:18.290 --> 02:48:20.955 One last point, the fact that these trees fall outside 02:48:20.955 --> 02:48:22.640 their right of way 02:48:22.640 --> 02:48:24.453 means that they need to tie their plans 02:48:24.453 --> 02:48:27.610 to the community wildfire protection plans. 02:48:27.610 --> 02:48:31.760 And PG and E has made no effort to do that. 02:48:31.760 --> 02:48:33.710 Please take these under consideration. 02:48:33.710 --> 02:48:35.410 Thank you very much for your time. 02:48:40.000 --> 02:48:40.833 Thank you. 02:48:40.833 --> 02:48:44.760 Our next public comment comes from Michael Agury. 02:48:44.760 --> 02:48:46.550 Please state your organization. 02:48:46.550 --> 02:48:47.453 Your line is open. 02:48:48.370 --> 02:48:49.430 Good morning. 02:48:49.430 --> 02:48:53.493 I'm an attorney for Amigi appearing before Judge Alsup. 02:48:54.410 --> 02:48:56.070 I wanna remind the listeners 02:48:56.980 --> 02:49:01.980 that the reason that PG and E has to shut off power 02:49:02.050 --> 02:49:06.230 is because it hasn't obeyed fire safety rules and laws 02:49:06.230 --> 02:49:07.153 for years. 02:49:08.040 --> 02:49:11.533 And the CPUC has let them get away with that. 02:49:12.810 --> 02:49:15.723 That's left us with two choices. 02:49:16.670 --> 02:49:20.030 We can have electricity with fires 02:49:20.030 --> 02:49:23.093 or no electricity without fires. 02:49:24.010 --> 02:49:28.290 Your response has been to issue PG and E licenses to burn 02:49:28.290 --> 02:49:29.923 called safety certificates. 02:49:30.890 --> 02:49:33.260 Your response to Judge Alsup's efforts 02:49:33.260 --> 02:49:35.870 to make PG and E improve safety 02:49:35.870 --> 02:49:39.200 is the forum you provided PG and E today 02:49:39.200 --> 02:49:44.160 to make a self-serving presentation with no sworn testimony, 02:49:44.160 --> 02:49:47.763 no cross examination, no evidence-based record. 02:49:48.640 --> 02:49:53.393 Instead of charades like what went on today, 02:49:54.300 --> 02:49:58.710 make safety certificates subject to evidence based 02:49:58.710 --> 02:50:02.090 administrative hearings with full rights 02:50:02.090 --> 02:50:03.453 of cross examination. 02:50:04.810 --> 02:50:07.390 I hope the Judge Alsup has watched 02:50:07.390 --> 02:50:10.240 this absurd exercise today 02:50:10.240 --> 02:50:13.060 and I hope that he will learn from it 02:50:13.060 --> 02:50:18.060 that you cannot trust the CPUC to step up and to do its job. 02:50:19.940 --> 02:50:20.773 Thank you. 02:50:26.240 --> 02:50:27.073 Thank you. 02:50:27.073 --> 02:50:28.860 Our next public comment comes from Dan Courtney. 02:50:28.860 --> 02:50:30.210 Please state your organization. 02:50:30.210 --> 02:50:31.133 Your line is open. 02:50:31.980 --> 02:50:34.513 I'm a member of the Sierra Club wildfire. 02:50:35.410 --> 02:50:38.395 Sorry, Sierra Club Utility Wildfire Prevention Task Force 02:50:38.395 --> 02:50:41.160 but I'm speaking today strictly as a property owner 02:50:41.160 --> 02:50:43.600 in Alameda County. 02:50:43.600 --> 02:50:47.060 We have a family property on the outskirts 02:50:47.060 --> 02:50:48.370 of Yosemite National Park 02:50:48.370 --> 02:50:50.830 surrounded by a Stanislaus National Forest 02:50:50.830 --> 02:50:55.803 with many old growth trees are 400 or 500 years old. 02:50:58.390 --> 02:51:02.470 So I've been paying attention to what's going on 02:51:02.470 --> 02:51:04.450 you know, for the past year or two 02:51:04.450 --> 02:51:08.390 since we had hundreds of trees on our properties 02:51:08.390 --> 02:51:10.490 marked for removal during 02:51:10.490 --> 02:51:14.380 the enhanced vegetation management markings inspections 02:51:14.380 --> 02:51:17.097 that happened in fall of 2019 02:51:17.097 --> 02:51:20.110 and what I've learned so far with doing a lot of research 02:51:20.110 --> 02:51:21.820 and participating a lot of meetings 02:51:21.820 --> 02:51:25.570 and reading a lot of information is that... 02:51:25.570 --> 02:51:30.570 Because I wondered, why are trees that are healthy and green 02:51:30.590 --> 02:51:34.142 and 150 feet away from a power line, 02:51:34.142 --> 02:51:36.690 how there was a threat to start a fire? 02:51:36.690 --> 02:51:39.383 And what I learned is it's not because the trees 02:51:39.383 --> 02:51:42.110 it's because they have these old wires 02:51:42.110 --> 02:51:44.650 like in our case there's 70 years old 02:51:44.650 --> 02:51:45.900 and they're uninsulated, 02:51:45.900 --> 02:51:50.400 they have like 14 splices, for example along the span, 02:51:50.400 --> 02:51:52.193 that's closest to our cabin. 02:51:53.570 --> 02:51:56.470 The power poles are short, they're wooden, 02:51:56.470 --> 02:51:58.560 they're burned, badly burned. 02:51:58.560 --> 02:52:02.170 They were burned in The Rim Fire, which was eight years ago 02:52:02.170 --> 02:52:04.310 and still not been replaced. 02:52:04.310 --> 02:52:05.760 They're looking now to replace them 02:52:05.760 --> 02:52:06.880 but they're gonna replace them 02:52:06.880 --> 02:52:09.810 with the same short end power poles. 02:52:09.810 --> 02:52:12.750 And they're not gonna change the wires, 02:52:12.750 --> 02:52:15.160 instead they're gonna put up bare wires. 02:52:15.160 --> 02:52:18.100 And so obviously that's the issue. 02:52:18.100 --> 02:52:19.557 The issue is the old equipment, 02:52:19.557 --> 02:52:24.550 the decades and decades of deferred maintenance by PG and E 02:52:24.550 --> 02:52:27.400 and my family has been a shareholder for 50 years 02:52:27.400 --> 02:52:29.254 and we appreciate the dividends 02:52:29.254 --> 02:52:32.730 but now really don't appreciate them as much 02:52:32.730 --> 02:52:35.020 knowing that they were earned 02:52:35.020 --> 02:52:38.810 at the cost of making virtually 02:52:38.810 --> 02:52:41.460 all parts of Northern California extremely dangerous. 02:52:42.420 --> 02:52:46.690 And so the focus is all centered on trees, County trees 02:52:48.170 --> 02:52:51.973 and in response to Judge Alsup's proposed order. 02:52:54.809 --> 02:52:57.659 So what's the time limit or how much time do I have left? 02:53:02.200 --> 02:53:03.300 Hello, I heard a beep. 02:53:04.183 --> 02:53:06.760 You have two minutes sir. 02:53:06.760 --> 02:53:09.580 Sorry, how much time left? 02:53:09.580 --> 02:53:11.240 No, your time is up. 02:53:11.240 --> 02:53:14.550 The bell sounded at the two minute mark. 02:53:14.550 --> 02:53:15.920 Oh I didn't realize it was two minutes. 02:53:15.920 --> 02:53:18.560 I would just like to close with one sentence 02:53:18.560 --> 02:53:23.380 and that is, please start focusing on ordering PG and E 02:53:23.380 --> 02:53:26.580 to modernize and upgrade its equipment. 02:53:26.580 --> 02:53:28.333 And also I think there should be a program 02:53:28.333 --> 02:53:31.400 to look at cost sharing between property owners 02:53:31.400 --> 02:53:33.384 who are willing to pay for under grounding 02:53:33.384 --> 02:53:35.860 but don't wanna foot the whole cost. 02:53:35.860 --> 02:53:38.070 And that would be beneficial to everyone 02:53:38.070 --> 02:53:40.260 in terms of accelerating the speed 02:53:40.260 --> 02:53:43.610 at which we have safe electricity through the mountains. 02:53:43.610 --> 02:53:45.708 PG and E should do at least a 50, 50 split 02:53:45.708 --> 02:53:47.634 with property owners. 02:53:47.634 --> 02:53:50.800 And then we could get some of these areas improved. 02:53:50.800 --> 02:53:51.990 Thank you for your time 02:53:51.990 --> 02:53:53.990 and for your attention to these matters. 02:53:57.000 --> 02:53:58.000 I currently have no other 02:53:58.000 --> 02:53:59.353 public comments in queue. 02:54:12.830 --> 02:54:13.835 Okay, well, we could go back 02:54:13.835 --> 02:54:17.450 to the presentation slides 02:54:17.450 --> 02:54:21.550 and there's a closing slide at the end 02:54:21.550 --> 02:54:22.993 right before the appendix. 02:54:37.731 --> 02:54:42.398 I think you need to advance to another couple of slides. 02:54:44.610 --> 02:54:45.920 Maybe go to the end. 02:54:55.266 --> 02:54:57.220 There we go, yeah. Thank you. 02:54:57.220 --> 02:55:01.730 I wanted to thank everyone who participated today 02:55:01.730 --> 02:55:03.830 and provided their insights and perspectives 02:55:03.830 --> 02:55:05.053 during public comment. 02:55:06.790 --> 02:55:09.800 The Commission and its staff will consider the information 02:55:09.800 --> 02:55:13.300 and act appropriately in particular, given the circumstances 02:55:14.240 --> 02:55:16.207 and considering the Federal Probation Proceeding 02:55:16.207 --> 02:55:19.640 and the workshop information provided. 02:55:19.640 --> 02:55:24.240 I wanted to reinforce that if parties, stakeholders 02:55:24.240 --> 02:55:27.730 and members of the public wish to provide written comments 02:55:27.730 --> 02:55:28.900 then please provide them. 02:55:28.900 --> 02:55:31.370 And in the next five business days 02:55:31.370 --> 02:55:33.976 by April 27th at five o'clock, 02:55:33.976 --> 02:55:37.830 please serve the written comments to the three proceedings 02:55:37.830 --> 02:55:40.490 that were given notice of the workshop. 02:55:40.490 --> 02:55:42.470 And this final slide provides a link 02:55:42.470 --> 02:55:45.293 to the Commission webpage related to service list. 02:55:48.750 --> 02:55:53.750 I think, unless there's any other closing remarks, 02:55:55.549 --> 02:55:59.513 we can conclude today's workshop. 02:56:05.140 --> 02:56:09.223 And thank you all again for your participation.
