PG&E's most recent request for a rate increase is now in the hands of state regulators. Despite that request, the company says customers may pay less next year due to some offsetting costs, but will still pay some of the highest electricity bills over the next five years. The company's CEO says the utility is a turnaround story in the making.

PG&E mistakenly notified 120,000 San Francisco customers of a power outage Saturday morning, when only about 9,400 customers were without power. 

PG&E says the outage began around 9:45 a.m. during a "routine operational procedure" between two utility substations. Initially, 9,400 customers near Golden Gate Park in the Richmond and Presidio were affected, PG&E said. 

By 3 p.m. that number was down to 1,595.

Power was restored for all customers at 4 p.m.

The cause of the outage is under investigation.

"We understand that any disruption in power is frustrating for our customers and we are committed to safe and quick restoration of service," the utility said.

120,000 PG&E customers incorrectly notified

When the outage first began, PG&E says its system incorrectly reflected that 120,000 customers were without power, notifying each of those customers.

"This morning, during a routine operational procedure between two San Francisco substations, protective devices activated and that caused an outage," PG&E said in a statement. "Due to the fact that two circuits were impacted, the outage notification system rolled up to a larger protective device, which indicated 120,000 customers were without power. That was not correct."

The utility said its notification system was corrected within 30 minutes.

Waymo impacted

Waymo, the autonomous car company, temporarily limited service in parts of the city during the outage, saying it was for an "abundance of caution."

"Waymo temporarily paused service for approximately one hour to assess local conditions. We have resumed service and are providing rides across the majority of our Bay Area service territory," a company representative said.
