SAN FRANCISCO (AP) – Pacific Gas & Electric Co. has restored power to more than 20,000 customers in Northern California after it shut it off over the weekend to guard against wildfires. PG&E spokesman Jeff Smith said Monday that power to all 20,500 affected customers in Butte and Yuba counties had been restored as of Sunday night. The utility also turned off electricity Saturday morning to 1,600 customers in Napa, Solano and Yolo counties amid windy, dry and hot weather. Power to those areas was restored later Saturday. Fire officials say a fire near the community of Guinda in Yolo County is 30 percent contained Monday. The 2,200-acre blaze started Saturday fueled by strong winds and hot temperatures. PG&E is under enormous pressure after downed power lines and other equipment have been blamed for previous devastating fires.
