Weeks after lethal fires swept by Los Angeles County, the state regulator answerable for overseeing utility corporations declined a request that might have required California’s largest utilities to replace maps displaying excessive fireplace risk areas.
Shopper advocates argued for extra up-to-date maps that would assist assess threat to communities and impose extra stringent necessities for utility infrastructure inside high-threat areas. The maps present the chance of a wildfire attributable to gear owned by the state’s three main investor-owned utilities; they’re separate from Cal Hearth’s maps that present the potential for fires primarily based on gas in a given space. Initially filed eight years in the past, the maps haven’t been up to date as a complete. As a substitute, the utilities voluntarily file piecemeal updates to mark areas as in danger for fireplace, or now not in danger, as they decide this with inner fashions.
Even with these additions, the maps badly want updating, in keeping with Cal Advocates, which represents ratepayers earlier than the California Public Utilities Fee.
A proposal from the company would have required instantly up to date maps and a shorter replace interval going ahead. Initially filed in 2023 by the California Public Advocates Workplace, a state entity tasked with representing shopper pursuits, it had assist from the three massive energy corporations – Pacific Gasoline & Electrical, Southern California Edison and San Diego Gasoline & Electrical. However in late January, the fee voted in opposition to the proposal, with 4 commissioners in opposition and one, who beforehand led Cal Advocates, who recused himself.
“The CPUC is concentrated on monitoring utilities’ compliance with quite a few guidelines and packages directing their actions in excessive fireplace risk areas of California,” Adam Cranfill, spokesperson for the fee, mentioned. “We can not remark immediately on a possible future car in regards to the fireplace maps.”
As investigators study the causes of the latest fires in Los Angeles County, Southern California Edison, which serves the realm, has come underneath elevated scrutiny. The utility mentioned in a regulatory submitting that its gear could have performed a task in beginning the 799-acre Hurst Hearth within the San Fernando Valley, and the corporate is investigating whether or not its gear could have been concerned within the 14,021-acre Eaton Hearth that burned Altadena and components of Pasadena.
Southern California Edison spokesperson Gabriela Ornelas declined to reply particular questions in regards to the utility’s fireplace maps and whether or not up to date maps would have helped stop or extinguish the latest fires or its response. In an announcement learn over the cellphone, she mentioned the corporate internally critiques the fireplace threat in its service space utilizing a number of components.
“Ought to that evaluation decide that adjustments to the CPUC maps are warranted, SCE will file a petition to change the map with the CPUC,” she mentioned.
The fee’s fireplace threat maps sprung out of a regulatory response to a sequence of fires in late 2007 in Southern California, a number of of which have been attributed to utility gear. Consequently, Pacific Gasoline & Electrical, Southern California Edison, and San Diego Gasoline & Electrical, which serve the overwhelming majority of the state, submitted maps in 2017 to determine potential areas the place utility gear may trigger fires.
The three utilities are required to replace their maps each 10 years, however each Pacific Gasoline & Electrical and Southern California Edison have up to date sections of their maps for the reason that authentic submitting. Southern California Edison can also be at the moment searching for approval to replace a portion of its maps. San Diego Gasoline & Electrical has not up to date its maps since 2017.
However Cal Advocates argued in its preliminary 2023 proposal that the maps want each a whole replace and to be up to date extra steadily than as soon as a decade. When Pacific Gasoline & Electrical filed an replace in 2023, for instance, the brand new inclusions amounted to about 4.5% of its service space.
“Even its most up-to-date mapping was in dire want of updating,” Cal Advocates mentioned in its 2023 request. “This means public security wants could be higher met if utilities throughout the state replace their wildfire threat mapping each 5 years.”
All three of the utilities with mapping necessities supported Cal Advocates’ place, which might permit the utilities to replace the maps primarily based on their very own inner fashions. In an announcement, Pacific Gasoline & Electrical spokesperson Matt Nauman mentioned the corporate updates its inner fireplace maps yearly and expects to file up to date maps with the fee on the finish of this 12 months.
Mussey Grade Street Alliance, a Ramona neighborhood advocacy group, pushed again on the proposal in Could 2023 due to the discretion it might give the utilities to decide on what counts as dangerous, which Cal Advocates later agreed with.
With the mapping comes extra regulatory scrutiny, in addition to extra stringent necessities for inspecting and sustaining utility infrastructure in high-risk areas.
The advocacy group’s Joseph Mitchell mentioned the maps lack adequate modeling for a way wind impacts the fires. The annual common of wind in an space doesn’t account for the short-term, important gusts that have been related to massive fires each just lately and throughout the final decade.
San Diego Gasoline & Electrical comes the closest to accounting for this, he mentioned.
Alex Welling, spokesperson for San Diego Gasoline & Electrical, mentioned the utility often compares its maps in opposition to “wind speeds, historic fireplace knowledge, fireplace modeling and extra.” The utility will file to replace the maps if it “identifies a necessity for updates,” Welling mentioned.
“Figuring out essentially the most harmful areas for applicable mitigation is essential and continues to be essential,” Mitchell mentioned.
