California power company begins new round of blackouts, trying to prevent wildfires

California's largest utility began another widespread blackout Wednesday that could affect hundreds of thousands of people as dangerous fire weather returns to California.

The Santa Rosa Fire Department tweeted that shutoffs had started in the city and it was getting multiple reports of outages.

Pacific Gas & Electric Co. previously said it would begin precautionary power shutoffs affecting nearly 180,000 homes and businesses in portions of 17 counties, mostly in the Sierra foothills and north of the San Francisco Bay Area.

The outages will last about 48 hours, the utility said.

Meanwhile, Southern California Edison said it could cut power Thursday to more than 160,000 customers in six counties and San Diego Gas & Electric was warning of power shutoffs to about 24,000 customers.

The utilities say they're concerned that winds forecast to top nearly 100km/hcould throw branches and debris onto power lines or topple them, sparking wildfires.

PG&E cut power to more than two million people across the San Francisco Bay Area in rolling blackouts from Oct. 9-12, paralyzing parts of the region in what was the largest deliberate blackout to prevent wildfires in state history. Schools and universities cancelled classes and many businesses were forced to close.

PG&E's new warning just two weeks later prompted a feeling of resignation among residents and business owners and renewed rushes to stock up on emergency supplies.

"I think it's not panic per se, just, 'Eh, we gotta do this again?"' said Kim Schefer, manager of Village True Value Hardware in Santa Rosa.

Schefer was busy Tuesday directing customers to gas cans and batteries as they prepared for what many see as a costly, frustrating new routine.

Love Birds Coffee & Tea in the old Gold Rush town of Placerville lost about $6,000 US in the last outage a huge chunk of change for a mom-and-pop business and a hit from which the store hasn't yet recovered, owner Garrett Sanders said.

"Working this close to the last outage is going to be a true trial by fire," he said.

This time, Sanders plans to brew up coffee and stock up on handmade pastries before the shutoff, then sell them on the sidewalk along with a smile when the power goes back on.

"It's going to be a sober morning for people waking up without their coffee," he said. "We can't do, like, all of our espressos and milk-based drinks but we'll have coffee. It'll be better than nothing."

Sanders said he is sympathetic to the argument that the outages are designed to prevent wildfires, especially since a dozen people settled in Placerville after they were burned out of the town of Paradise by a fire that killed 85people last year.

"Of course, none of us wants the devastation" of a wildfire, Sanders said, "but I think the measures that PG&E is taking are to the ultimate extreme."

California Gov. Gavin Newsom sent a sharply worded letter Tuesday to Bill Johnson, PG&E's chief executive, blaming the unprecedented mass outage earlier this month on the company's failure to maintain and upgrade its equipment.

"I believe the unacceptable scope and duration of the previous outage deliberately forcing 735,000 customers to endure power outages was the direct result of decades of PG&E prioritizing profit over public safety," the Democrat wrote, referring to the number of businesses and households affected, not the total number of people.

PG&E says the shutdowns are not about money.

The only goal "is to prevent a catastrophic wildfire," Johnson said in a Tuesday briefing.
