PG&E slowed fire-risk mapping of power lines
SAN JOSE — Two days before the deadliest outbreak of wildfires in California history, PG&E and other utilities won the latest in a long series of delays to map where power lines pose the greatest wildfire risk, a report said Sunday.
For the better part of a decade, California’s utilities have helped to stall the state’s effort to map where their power lines present the highest risk for wildfires, an initiative that critics say could have forced PG&E to strengthen power poles and bolster maintenance efforts before this month’s deadly North Bay fires.
State officials began working to tighten regulations on utilities and create the detailed maps after wind-toppled electrical lines in 2007 ignited catastrophic fires in the San Diego area.
But nearly 10 years later, the state Public Utilities Commission — which initiated the process — still hasn’t finished the maps, let alone adopted strict new regulations.
A review of the mapping project by the Bay Area News Group shows that utilities have repeatedly asked to slow down the effort and argued as recently as July that, as PG&E put it, certain proposed regulations would “add unnecessary costs to construction and maintenance projects in rural areas.”
On Oct. 6, two days before the fires, two administrative law judges assigned to oversee the project granted yet another delay at the request of PG&E and other utilities.
The timing of that 74-day deadline extension and the decade of seemingly endless debate about the maps has outraged lawmakers who have been pushing regulators for years to speed up a project designed to prevent catastrophic fires like the ones in Northern California that killed at least 42 people and destroyed more than 8,000 homes and businesses.
“The sad part is the future didn’t arrive before these fires,” said state Sen. Jerry Hill, D-Redwood City, a longtime critic of PG&E and the PUC. “It’s an outrageous example of negligence by a regulatory agency.”
Authorities are still investigating what started multiple North Bay wildfires on Oct. 8, when heavy winds downed power poles, transformers and electrical lines.
But one prime suspect is PG&E’s infrastructure.
Hill and other critics have characterized the yearslong state regulatory efforts as a long, meandering slog, with hundreds of utilities, telecommunication companies, internet providers and other stakeholders fighting over proposed regulations that could add significant costs to their bottom line.
In October 2016, PG&E complained to a judge that the PUC’s plans to complete the map by March of this year was “too aggressive.” And in July, the utility called a proposed regulation to increase the wind speed that power poles must sustain “arbitrary.”
Within the first 90 minutes of the fires in Sonoma and Napa counties, firefighters received reports of at least 10 blown transformers or downed power lines at the same time they were called out to battle 19 structure and vegetation fires.
PG&E has acknowledged that some of its lines and poles went down that first night of the fires, citing drought-ravaged trees and what it insisted was a “historic wind event.” But the Bay Area News Group found that the winds when the fires were first reported were roughly half the speed that power poles and lines are required by law to withstand.
