Hundreds of PG&E customers in Los Osos were without power for days thanks to a faulty transformer and subsequent repair issues.
Crews completed work Saturday afternoon on an underground transformer on Pecho Valley Road near Monarch Lane that left customers without power since 6:32 p.m. Thursday.
Temporary generators lowered the number of affected customers from 238 to 120.
The substitute transformer to replace the broken transformer on Thursday was also faulty and required another, new transformer to be brought to the site.
Another outage in Atascadero that affected about 1,600 people lasted from 8 a.m. until 9:30 a.m. The location of that outage straddled Highway 101, south of San Rafael Road, extending to near San Diego Road on the south end, and east past Bocina Lane and Calle Milano.
