Power may be shut off in eight Northern California counties early Thursday due to fire concerns, according to PG&E.PG&E said Tuesday the Red Flag Warning from the National Weather Service and other weather factors leading to extreme fire danger are reasons for proactively shutting off power in some parts of those counties."We know how much our customers rely on electric service and the impacts these events can have on our customers, their families and communities," senior vice president of Electric Operations Pat Hogan said in a statement. "We will only consider temporarily turning off power in the interest of safety and as a last resort during extreme weather conditions to reduce the risk of wildfire."The areas are expected to see windy conditions and winds gusts from overnight Wednesday through Thursday afternoon, PG&E said.| RELATED | PG&E power shutdown: What you need to know about the futureAbout 63,000 people could be impacted by the shutoff. The following counties and cities may have their power shut down:Butte County (including Berry Creek, Chico, Forest Ranch, Magalia, Oroville, Paradise)Lake County (including Clearlake Oaks, Cobb, Hidden Valley Lake, Kelseyville, Middletown)Napa County (including Angwin, Pope Valley, St. Helena)Nevada County (including Grass Valley, Nevada City, North San Juan)Placer County (including Colfax, Foresthill, Alta)Plumas County (including La Porte)Sierra County (including Downieville, Sierra City) Yuba County (including Brownsville, Dobbins, Camptonville)| RELATED | PG&E defends decision to shut off power to thousands in NorCalLate Wednesday, PG&E took Sonoma County off the list of counties that could be impacted by the power shutoff.“Once the weather conditions that made the power shutoff necessary pass, we have to go through and inspect all those lines visually to make sure that there was no damage," PG&E spokesperson Denny Boyles said. "We know that following the previous shutoff, we did find damage to equipment. So, we’ll go through and once we’ve checked the circuit, we’re able to restore that circuit. So, that’s why you can see some instances where power to one community might be restored much sooner than power to another.”Officials said Wednesday night that there are 800 helicopters on standby to check power lines if power is shut off, compared to the 300 that checked lines after last time's power shut off.PG&E said it is working with first responders and local agencies during this time. It is also sending notifications via text, email and voicemail to alert customers of a possible shutoff. Several residents in El Dorado County erroneously got phone messages from PG&E about the possible shutoff, officials said Wednesday.The El Dorado Sheriff's Office posted on Facebook that the possible shut off will not impact county residents. PG&E said the calls were a mistake but couldn't say how many people got the phone calls.RESIDENTS REACTResidents in impacted areas have mixed reactions to the possible power shutoff.“Personally, I think that they're probably doing the right thing so that we don't burn up everybody's property,” Foresthill business owner Bobby Adams said. “And, we have to deal with not having power for a while in the interest of safety.”Adams runs Foresthill Garage. He said he ordered a generator to power the auto repair shop in case the power is cut off.“The last time, we were out for about 20 hours and it was very difficult for us,” business owner Patrick Thompson said. “I mean we’re sitting up here, and customers are being turned away because we’re an all-electric restaurant. And so, if I have no power, I can’t cook.”Thompson owns Mega’s Café in Foresthill, which lost $1,000 during the previous pre-preemptive fire safety shutoff. He thought about getting a generator; he said the lowest bid he got to power the restaurant was $12,000.PG&E said it doesn’t plan on reimbursing claims filed by people affected by power shutdowns because they are a safety measure the company cannot prevent.In Calistoga, dozens of residents attended a PG&E public meeting Wednesday night to talk about the possible power shutoff. The utility installed temporary generators in the city, saying Calistoga is in a low-risk fire area. Officials explained power lines that energize the city run through high-risk areas and could be shut off, leaving Calistoga in the dark.“When I lived in Los Angeles, I think the power was turned off twice in my 30 years there,” said Deborah Testa, who attended the meeting. “Since I moved to Calistoga, I would say the power’s gone off no fewer than 30 times.”Testa said the thought of losing her power again is daunting.Her electricity was turned off during PG&E’s safety power shutdown last month.“When they voluntarily shut the power down, it was a deep shock,” Testa said. “It felt like a huge imbalance. You have this multimillion-dollar corporation with a lot one the line. Then you have me. I’m the only person in my business. If I’m not working, nothing is working.”Testa, like several other Calistogans at Wednesday’s meeting, said her business lost money during the safety power shutdown. She runs a data analysis company and works remotely.“I need to have that connection,” she said. “If you pull the plug, I’m not working. You put the plug back in, I’m working. It’s that literal.”Testa said she is happy PG&E installed the temporary generator but said she’s lost faith in the company. She said she’s looking into purchasing a home battery. “I’ve gotten to the point where I’m willing to stop relying on PG&E because they are not going to support my business,” Testa said. “They will pull the plug when they think they need to.”
