SAN FRANCISCO — When California’s largest utility warned it would cut power to thousands to prevent its equipment from starting wildfires during warm, windy weather, officials in the wealthy wine region of Sonoma County sprang into action.
They declared a state of emergency and called up additional first responders who could direct traffic or take vulnerable residents to places with electricity.
Nearly 200 miles north, officials in rural Butte County simply posted Pacific Gas & Electric information online about which neighborhoods would be affected and what to do with perishable food.
Both counties had communities decimated in wildfires ignited by power lines in recent years. They face the long-term prospect of frequent power shutoffs during fire season as PG&E and other utilities try to prevent their equipment from sparking blazes like the one last year that killed 85 people and nearly destroyed the Butte County town of Paradise.
More populated, wealthier counties have adapted their emergency plans to respond to the new reality of thousands of residents losing power for an undetermined amount of time. But the preventive outages are proving to be a burden to smaller, poorer counties without resources to set up places for people to cool off or mobilize staff to deal with emergencies if outages stretch past two days.
“The outages are to avoid an emergency and a fire disaster, but there are no resources that counties can access to make sure that people are at a cooling station or get the transportation they need to get there,” said Darby Thomas, deputy executive director of the California State Association of Counties.
California lawmakers this year set aside $75 million to prepare local governments for the outages, but officials have yet to decide how to distribute the money.
The outages are new for PG&E and Southern California Edison, which together provide power in 55 of California’s 58 counties. The utilities and county officials are working together to figure out their roles, but a lack of standards has led to disparate responses.
This week, PG&E shut off power to more than 48,000 customers in seven counties in wine country and the Sierra Nevada foothills as the humidity plunged, temperatures rose and winds kicked up — a combination that has fueled some of the most destructive blazes in California history.
The outages lasted less than a day, and no major problems were reported.
In Sonoma County, PG&E cut power to 700 people in the Santa Rosa area, where a massive blaze in October 2017 killed 22 people and destroyed 5,000 homes.
The county started planning for power outages shortly after regulators approved them in May, emergency management director Chris Godley said.
“Just like we prepare for an earthquake, or fire season, or flood season, we also prepared for the de-energization because if the power will be out for more than 48 hours, it’s really an emergency for the community,” he said.
The county’s outage plan calls for opening facilities with air conditioning, adding more police patrols to direct traffic after streetlights go out and sending workers to check on those who are sick or immobile.
“Our response philosophy is to ensure maximum and full response immediately because we don’t know the level and scope of what’s going to happen,” Godley said.
In Butte County, where 24,000 customers lost power twice this week, authorities ensured backup generators worked, had staffers ready in case they needed to check on vulnerable people and shared PG&E updates on social media. They planned to rely on two PG&E cooling centers.
“Our role is to make sure the information gets out there because it’s really PG&E’s thing,” county spokeswoman Miranda Bowersox said.
Lake County, home to 60,000 people in the Sierra foothills where wildfires in recent years killed four people and burned hundreds of buildings, emergency officials have spent $500,000 installing generators that can power police, fire, water and sewage services.
It doesn’t have the resources to do much more than ensure government buildings are operating during an outage, said Dale Carnathan, county emergency services manager.
