SAN FRANCISCO (KRON) — A power outage Wednesday night affected more than 9,000 customers in San Francisco’s Financial District, North Beach, Russian Hill, and Nob Hill neighborhoods, according to PG&E.

As of Saturday evening, power in those affected areas has been fully restored, PG&E confirmed in an email to KRON4. Affected areas in the city had their power back on by approximately 4:45 p.m.

The outage was due to damage from underground equipment near Clay Street and Montgomery Street, PG&E said. The cause of the damage is still under investigation.

The outage caused a number of traffic lights in the area to be shut down for multiple days.
