In March, SCE filed its 2023 through 2025 WMP with the Office of Energy Infrastructure Safety. Highlights of the plan are shown on page 3. Our number one priority remains the safety of the public, customers, workers, and first responders. In 2023, the utility is building on the work already accomplished while focusing on five key areas: continuing to harden the grid, ramping up targeted undergrounding work in severe risk areas, continuing to reduce PSPS impacts, expanding aerial fire suppression funding to year-round, and furthering technological advancements.
SCE’s flagship grid hardening program, covered conductor, remains its key mitigation measure. More than 2,850 additional miles of covered conductor will be installed between 2023 and 2025. By the end of 2025, SCE expects to have replaced more than 7,200 miles, or about three quarters, of overhead distribution power lines in high fire risk areas with covered conductor. SCE also plans to complete about 100 miles of undergrounding by 2025 to address the high risk presented by unique factors in certain areas, and plans to underground a total of 600 miles by the end of 2028. Additionally, to quickly suppress fires regardless of how they start and protect the communities SCE serves, the utility continues to partner with the LA County Fire Department, Orange County Fire Authority, and Ventura County Fire Department to expand their firefighting capabilities. As highlighted in the WMP, this support has been expanded to year-round aerial fire suppression from the Quick Reaction Force, made up of the world’s largest fire-suppression helicopters with unique night firefighting capabilities.
The WMP is adaptive and focused on furthering technological advancements to find new ways to mitigate wildfire risk. SCE is continuously developing new approaches and collaborating with other utilities, academia, and the energy sector to make our communities safer. The WMP highlights technologies, such as the Rapid Earth Current Limiter, Early Fault Detection, and using artificial intelligence, that will continue to advance our suite of wildfire mitigation measures.
A key long-term driver for SCE’s investment in the grid and for enabling customer affordability is transportation electrification. We aren’t just talking about regulatory policies or
