CLAYTON, Calif. – As the utility forewarned, Pacific Gas & Electric turned off power to a portion of customers, mostly in the East Bay, on Thursday in a preventive measure to reduce the risk of wildfires as high winds and dry conditions are expected through Saturday.
Power was shut off in Clayton, a city in Contra Costa County at the base of Mount Diablo State Park, at 4:47 a.m. and PG&E told the 73 customers affected that it would be restored as soon as it is safe.
By noon, PG&E had also shut off power to areas near Livermore, Lake del Valle, Byron, Altamont Pass Road, Sycamore Grove Regional Park, an area along Interstate 580 west of Tracy, and homes south of Discovery Bay.
PG&E warned earlier this week that customers in parts of Alameda, Contra Costa, Napa, Santa Clara and Sonoma counties may also be temporarily shut off during these high-risk fire conditions.
As of now, the areas identified for potential shutoffs are primarily in remote regions.
Thursday afternoon, a spokesperson for PG&E estimated about 650 customers were either shut off or planned to be shut off in Alameda County, about 275 in Contra Costa County, and about 50 in Santa Clara County.

To check for your neighborhood, PG&E has provided an outage map.
PG&E has paid millions in fines and was criminally convicted of involuntary manslaughter stemming from at least 30 wildfires since 2017 that have wiped out thousands of homes and killed more than 100 people.
Some of those fires were caused by the utility’s power lines that sparked while electricity was running through them.
