Southern California Edison Files Annual Update to Wildfire Mitigation Plan|||

The 2022 update builds upon considerable progress to further reduce the chance of fires caused by utility infrastructure and the frequency and bear upon of PSPS

Wildfire mitigation piece of work volition increase grid reliability and climate resilience, enhancing a strong foundation for the clean free energy transition

ROSEMEAD, Calif.–(Business concern WIRE)–Southern California Edison today filed its annual update to its 2020-2022 Wildfire Mitigation Program with the California Office of Energy Infrastructure Prophylactic. The 2022 plan has an ambitious mission to continue to strengthen and adapt the grid to withstand farthermost weather events probable exacerbated past climatic change, including the installation of more than insulated wire.

“SCE’s commitment to keep our communities rubber remains steadfast, and our plan this year demonstrates the tangible means that we continue to brand the grid safer and more reliable as we ameliorate support our customers,” said Jill Anderson, SCE executive vice president of Operations. “It includes measures to reduce the frequency and bear upon of Public Safety Power Shutoffs (PSPS). While we but apply PSPS equally a concluding resort during extreme weather conditions, we recognize that these outages are difficult, particularly for frequently impacted communities and our most vulnerable customers.”

Continued Work to Strengthen the Grid

SCE began implementing new wildfire mitigation activities in 2018. This latest update reflects the connected progress the visitor has made in its analytical, engineering and process maturity and incorporates lessons learned from prior years.

Through grid hardening, enhanced inspections, expanded vegetation management and targeted PSPS, along with a suite of other activities the company undertook, SCE estimates that it has reduced the risk of damage from catastrophic wildfires by 65% to 70%, relative to pre-2018 levels. Year over year, the total number of acres burned from wildfires associated with SCE equipment decreased from 128,000 acres in 2020 to less than 500 acres in 2021. This was despite the multi-year drought and farthermost wind weather condition experienced concluding yr. This comeback could non accept occurred without the partnership and dedicated efforts of many leaders throughout the state.

While information technology can never be fully eliminated, SCE expects to further reduce take a chance with the piece of work outlined in our 2022 Wildfire Mitigation Program update and reduce the size and scope of PSPS events. With work completed last year, the company estimates that customers on the nearly frequently impacted circuits experienced 70% less PSPS outage time based on 2021 weather and fuel conditions.

SCE is updating its grid hardening strategy this year. Covered conductor installation supplemented with inspection and vegetation management continues to exist ane of the nigh valuable tools in reducing ignition risk cost effectively and expeditiously. Even so, SCE is evaluating the expanded use of undergrounding and additional applied science solutions for sure locations that pose very high risks based on potential burn spread, burn down history, limited egress and farthermost air current speeds.

One of the emerging applied science pilots that has shown promise in further reducing the gamble of ignition is the Rapid World Fault Current Limiter (REFCL). REFCL is a applied science that detects a power line has fallen to the footing and can almost instantly reduce the energy released to the basis, which resembles the mechanism of a ground fault excursion interrupter in people’southward homes.

SCE is likewise exploring the use of artificial intelligence-based applied science to detect wildfires. The program uses satellite imagery in conjunction with SCE’due south loftier-definition camera network and information technology may warning fire agencies about possible fire starts if the airplane pilot is successful.

Community Outreach and Partnerships

The visitor will continue to support the resiliency needs of Medical Baseline and Access and Functional Needs (AFN) customers, such as seniors, those with limited English proficiency, those with disabilities and those who face up transportation challenges. An example of this is a new battery loan airplane pilot program to support AFN customers who rely on a medical device or assistive technology for independence, health or safety.

Another program that volition continue is SCE’s back up to bolster aerial fire suppression. Last year, the Los Angeles Canton Fire Section, Orange Canton Burn Authority (OCFA), Ventura County Fire Department and other regional agencies partnered with SCE to expand their capabilities with a Quick Reaction Force of the earth’s largest burn-suppression helicopters. The Quick Reaction Force consisted of two Coulson-Unical CH-47 helitankers that tin can each bear upwardly to 3,000 gallons of water or retardant, a Sikorsky-61 that tin carry up to i,000 gallons of water or retardant, a Sikorsky-76 helicopter and a mobile fire retardant base that tin actively mix upwardly to xviii,000 gallons of fire retardant per hour.

The helitankers function during the day and at night, which typically is the best time to finish wildfires, as winds die down, temperatures ease and humidity rises. Last yr, the fleet fabricated two,192 total drops with 823 of them at nighttime, which amounted to two.ix one thousand thousand gallons of water and 139,000 gallons of burn down retardant.

“As the scope and intensity of wildfire season go on to grow, nosotros are proud to seek out partners that are as committed to innovating new measures that salvage lives and protect property,” said OCFA Burn down Main Brian Fennessy. “Southern California Edison is such a partner, and our gratitude for their back up — from the helitankers of our Quick Reaction Force to fire-resistant poles and a vegetation direction program — is matched only past the impact of their actions.”

SCE has instituted a formal feedback procedure to aid accost specific critiques and recommendations. This includes the company’s engagement effort with communities heavily impacted past PSPS events and actively evaluating and refining stakeholder coordination and customer outreach approaches based on feedback received subsequently by PSPS events.

“Our wildfire mitigation work will increase the reliability and climate resilience of the grid,” Anderson said. “These filigree upgrades further strengthen a solid foundation for the make clean energy transition, supporting the electrification of transportation and buildings needed to meet California’s climate change and air quality goals.”

Final year, the implementation of the wildfire mitigation program cost $1.66 billion and the company expects to spend approximately the same amount this year.
