According to annual wildfire mitigation plans filed with the California Public Utilities Commission (CPUC) on February 5, 2021, PG&E, Edison International's Southern California Edison (SCE) and Sempra Energy's San Diego Gas & Electric (SDG&E) plan to spend $15 billion in 2021 and 2022 to reduce the risk of live wires sparking wildfires.[1] The CPUC began requiring utilities to file annual wildfire mitigation plans after power lines ignited a series of fires in 2017 and 2018. PG&E’s 2021 plan will cost $5 billion in 2021 and $5.2 billion in 2022. The utility will use a new fire risk model to prioritize its wildfire mitigation work, including system hardening and tree trimming. SCE plan outlines strategies such as installing an additional 1,000 to 1,400 miles of insulated powerlines and installing 375 weather stations in its service territory. SCE expects to spend $3.5 billion in 2021 and 2022. SDG&E plans to spend over $646 million in 2021 and nearly $670 million in 2022 on wildfire mitigation. The utility will continue with many of the programs it initiated last year, including expanding outreach to vulnerable communities and strengthening data collection and analyses processes. All three utilities aim to reduce the impact of public safety power shut-offs (PSPS) on their customers.
