Overview
- Roughly 130,000 PG&E customers lost power across San Francisco after outages that started in the west early Saturday.
- PG&E said the grid is stabilized and it does not expect further losses, yet it has offered no firm estimate for full restoration.
- A fire inside a PG&E substation was cited by a fire department official as a cause of part of the blackout.
- Transit and traffic were snarled, with darkened signals and BART trains temporarily skipping downtown stations.
- Waymo suspended its driverless service during the outage as Mayor Daniel Lurie urged residents to stay off the roads.
