Weeks after lethal fires swept by way of Los Angeles County, the state regulator in command of overseeing utility corporations declined a request that may have required California’s largest utilities to replace maps exhibiting excessive fireplace risk areas.
Client advocates argued for extra up-to-date maps that might 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 brought on by tools owned by the state’s three main investor-owned utilities; they’re separate from Cal Fireplace’s maps that present the potential for fires based mostly on gas in a given space. Initially filed eight years in the past, the maps haven’t been up to date as an entire. As an alternative, the utilities voluntarily file piecemeal updates to mark areas as in danger for fireplace, or not in danger, as they decide this with inner fashions.
Even with these additions, the maps badly want updating, in response to 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 client pursuits, it had help from the three giant energy corporations – Pacific Fuel & Electrical, Southern California Edison and San Diego Fuel & Electrical. However in late January, the fee voted towards the proposal, with 4 commissioners in opposition and one, who beforehand led Cal Advocates, who recused himself.
“The CPUC is targeted 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 concerning the fireplace maps.”
As investigators look at the causes of the latest fires in Los Angeles County, Southern California Edison, which serves the realm, has come beneath elevated scrutiny. The utility mentioned in a regulatory submitting that its tools could have performed a task in beginning the 799-acre Hurst Fireplace within the San Fernando Valley, and the corporate is investigating whether or not its tools could have been concerned within the 14,021-acre Eaton Fireplace that burned Altadena and elements of Pasadena.
Southern California Edison spokesperson Gabriela Ornelas declined to reply particular questions concerning 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 a press release learn over the telephone, she mentioned the corporate internally evaluations the hearth threat in its service space utilizing a number of elements.
“Ought to that evaluation decide that modifications 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 tools. Consequently, Pacific Fuel & Electrical, Southern California Edison, and San Diego Fuel & Electrical, which serve the overwhelming majority of the state, submitted maps in 2017 to establish potential areas the place utility tools might trigger fires.
The three utilities are required to replace their maps each 10 years, however each Pacific Fuel & Electrical and Southern California Edison have up to date sections of their maps for the reason that authentic submitting. Southern California Edison can be at present in search of approval to replace a portion of its maps. San Diego Fuel & Electrical has not up to date its maps since 2017.
However Cal Advocates argued in its preliminary 2023 proposal that the maps want each an entire replace and to be up to date extra continuously than as soon as a decade. When Pacific Fuel & 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 implies 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 based mostly on their very own inner fashions. In a press release, Pacific Fuel & 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 yr.
Mussey Grade Street Alliance, a Ramona group advocacy group, pushed again on the proposal in Might 2023 due to the discretion it will give the utilities to decide on what counts as dangerous, which Cal Advocates later agreed with.
With the mapping comes further 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 ample modeling for the way wind impacts the fires. The annual common of wind in an space doesn’t account for the short-term, vital gusts that have been related to giant fires each not too long ago and throughout the final decade.
San Diego Fuel & Electrical comes the closest to accounting for this, he mentioned.
Alex Welling, spokesperson for San Diego Fuel & Electrical, mentioned the utility often compares its maps towards “wind speeds, historic fireplace information, fireplace modeling and extra.” The utility will file to replace the maps if it “identifies a necessity for updates,” Welling mentioned.
“Figuring out probably the most harmful areas for applicable mitigation is vital and continues to be vital,” Mitchell mentioned.
