Power was restored to over 6,000 customers in Excelsior, Portola and Balboa Park at 1 p.m. Monday. PG&E says the cause of the outage is still under investigation.
Customers began reporting blackouts at 11:20 a.m., according to PG&E live data. The provider assessed at 11:51 a.m. that 6,233 households had been affected, and initially estimated the outage would be resolved by 5 p.m. Monday.
In a preliminary assessment of the outage, PG&E said the blackout was caused by scheduled maintenance work, live data showed. The cause was changed to “unknown” around 12:40 p.m.
By 12:25, most customers were restored and just an estimated 1162 remained in the dark, PG&E spokesperson Tamar Sarkissian told The Examiner.
“If you ever see a low or downed power line, always assume is live, keep yourself and other away, and call 911 and PG&E immediately,” Sarkissian said.
Monday’s outage was preceded by another twice its size Sunday that left 13,000 customers in the dark after a piece of equipment at a PG&E substation failed, Bay City News reported.
