At about 12:30 p.m., PG&E customers in the Inner Richmond and a portion of Western Addition neighborhood experienced flickering lights and outages, PG&E spokesman Joe Molica said.
Crews responded and found a load imbalance in a substation, Molica said.
“A load imbalance is a situation where one circuit may have more load on it than another,” he explained.
PG&E crews fixed the problem, and full electricity was restored by 1:25 p.m., Molica said.
The imbalance could be caused by a number of factors, and an investigation into the cause is ongoing, Molica said.
“We want to apologize to our customers for any inconvenience,” Molica said.
