Fifteen California counties and 209,000 premises may lose electricity once again on the heels of the largest imposed power outage in state history, the bankrupt utility Pacific Gas and Electric announced the afternoon of Oct. 21. 

Imposed during dry, windy weather to reduce the risk that PG&E’s equipment will spark wildfires, this week’s potential power outages may begin at different times for different counties, starting Wednesday evening. 

The outage is expected to affect portions of San Mateo, Sonoma, Alpine, Amador, Butte, Calaveras, El Dorado, Lake, Mendocino, Napa, Nevada, Placer, Plumas, San Mateo, Sierra, Sonoma, Sutter and Yuba.

The utility will open community resource centers providing restrooms, bottled water, charging stations, seating and air conditioners. They’ll be staffed from 8 a.m. to 6 p.m. during the outages. For more information about the resource centers and the outages, visit pge.com.
