People in more than 180,000 homes and businesses in California could find themselves in the dark as Pacific Gas & Electric again plans to shut off power in parts of 17 counties for up to two days, as a preventive measure against wildfires.
The company said it was tracking a “dry, offshore wind event” that might impact its service area on Wednesday and Thursday and needed to turn off the electricity as a safety measure.
Hot, dry winds from California’s mountains, called the Santa Ana winds, are expected to pack a 40 mph punch, with gusts up to 60 mph, starting late on Wednesday, the National Weather Service said.
“It’s a hot, dry wind with all the moisture wrung out of it and it can bring some of the hottest temperatures of the year to Los Angeles, San Diego, basically southern California,” said David Roth, a forecaster with the NWS’s Weather Prediction Center in College Park, Maryland.
“Power lines can get knocked down and start fires in the dry trees and vegetation. This is a real danger. This event will last probably through Friday,” Roth said. “It’s a critical fire danger.”
The company cut off electricity to more than 730,000 homes and workplaces in northern California earlier this month to try to reduce wildfire risks posed by extremely windy and dry weather.
The bankrupt Californian power producer said it had crews, equipment, vehicles and aircraft on standby to conduct the shutoffs and subsequent inspections, repairs and power restoration.
In some areas, the company said it has reduced the scope of impact as it was able to sectionalize certain lines.
In May, state fire investigators determined that PG&E transmission lines caused the deadliest and most destructive wildfire on record in California, last year’s wind-driven Camp Fire that killed 85 people in and around the town of Paradise.
Cal Fire likewise concluded that PG&E power lines had sparked a 2017 flurry of wildfires that swept California’s wine country north of San Francisco Bay.
The company, whose handling of recent power outages has been criticized over insufficient communication with customers, sent out 48-hour advance notifications to customers on Monday afternoon informing them that it may be proactively turning power off for safety.
PG&E filed for bankruptcy in January, citing potential civil liabilities in excess of $30 billion from the fires.
