Hot, dry winds sweeping into Southern California raised concerns that the region’s largest utility could widen power shut-offs Friday to prevent its equipment from sparking wildfires.
Southern California Edison turned off electricity to about 20,000 people in Los Angeles, Ventura, San Bernardino and Kern counties but warned that thousands more could lose service as Santa Ana winds gained strength.
Winds gusted dangerously as forecast before calming in Northern California, where Pacific Gas & Electric faced hostility and second-guessing over its widespread shut-offs.
The fire danger spread to Southern California on Thursday as raging winds moved down the state.
A blaze ripped through a mobile home park in Calimesa, a city about 65 miles (104 kilometers) east of Los Angeles, destroying dozens of residences. The fire started when trash being hauled caught fire and the driver dumped the load aside a road, according to Riverside County officials. An 89-year-old woman, Lois Arvickson, is missing, according to her son.
Gov. Gavin Newsom criticized PG&E and ordinary customers complained about the inconveniences caused by the unprecedented blackouts that began midweek, with many wondering: Did the utility go too far in its attempt to ward off more deadly fires? Could it have been more targeted in deciding whose electricity was turned off and when?
PG&E, though, suggested it was already seeing the wisdom of its decision borne out as gusts topping 77 mph (122 kph) raked the San Francisco Bay Area amid a bout of dry, windy weather.
“We have found multiple cases of damage or hazards” caused by heavy winds, including fallen branches that came in contact with overhead lines, said Sumeet Singh, a vice president for the utility. “If they were energized, they could’ve ignited.”
Because of the dangerous weather in the forecast, PG&E cut power Wednesday to an estimated 2 million people in an area that spanned the San Francisco Bay Area, the wine country north of San Francisco, the agricultural Central Valley and the Sierra Nevada foothills. By Thursday evening, the weather had eased and the number of people in the dark was down to about 510,000.
Inspections and repairs were expected to resume at daybreak and power could be restored Friday to many more customers, Singh said.
PG&E cast the blackouts as a matter of public safety, aimed at preventing the kind of blazes that have killed scores of people over the past couple of years, destroyed thousands of homes, and ran up tens of billions of dollars in claims that drove the company into bankruptcy.
CEO Bill Johnson didn’t respond to Newsom’s criticisms but promised if future wind events require similar shut-offs, the utility will “do better” when it comes to communicating with customers. It’s unacceptable that its websites crashed, maps were inconsistent and call centers were overloaded, Johnson said.
“We were not adequately prepared,” he said.
Many of those affected by the outages, which could last as long as five days, were not so sure about the move.
Sergio Vergara, owner of Stinson Beach Market, situated on scenic Highway 1, on the Pacific Coast just north of San Francisco, operated the store with a propane generator so his customers could have coffee, milk, meat and frozen meals.
“I’m telling you as a plain human being, there is no wind, there is no heat,” he said. “We never saw something like this where they just decide to shut off the power, but on the other side — preventing is a good thing, but it’s creating a lot of frustration.”
But in powered-down Oakland, Tianna Pasche said: “If it saves a life, I’m not going to complain about it.”
Faced with customer anger, PG&E put up barricades around its San Francisco headquarters. A customer threw eggs at a PG&E office in Oroville. And a PG&E truck was hit by a bullet, though authorities could not immediately say whether it was targeted.
The governor said PG&E was to blame for poor management and should have been working on making its power system sturdier and more weatherproof.
“It’s decisions that were not made that is leading to this moment in PG&E history,” Newsom said. “This is not from my perspective a climate change story so much as it is a story of greed and mismanagement over the course of decades.”
Marybel Batjer, president of the California Public Utilities Commission, blasted PG&E’s communication and said the situation was unacceptable.
Experts say the big shut-off will yield important lessons for the next time.
Deliberate blackouts are likely to become less disruptive as PG&E gets experience managing them and rebuilds sections of the grid so that outages can be more targeted, said Michael Wara, a researcher on energy and climate policy at Stanford University.
Grids are built and operators are trained to keep the power on at all times, so the company and its employees have little experience with intentionally turning the electricity off in response to rapidly changing weather, he said.
“That’s a skill that has to be learned, and PG&E is learning it at a mass scale right now,” Wara said.
After a June shut-off in the Sierra foothills, PG&E workers reported repairing numerous areas of wind damage, including power lines hit by tree branches.
“That was worth it,” Wara said of the deliberate blackout. “That could have prevented a catastrophe.”
