Crews have restored power to most of the 145,000 Pacific Gas and Electric Co. customers hit by a weekend outage that darkened a large part of California's Central Coast.
An outage map on the company's website shows just one customer in Santa Maria remains without electricity early Monday morning.
Santa Maria, which has about 100,000 residents, was the largest city affected by the Sunday night outage that stretched from the beach town of Cambria in San Luis Obispo county to Solvang in Santa Barbara's wine country.
PG&E tweeted that equipment failure at a substation caused the outage.
No major problems were reported, although one hospital canceled a surgery.
Watchdogs are questioning an exclusive agreement between the City of Oakland and a non-profit group, tapped to lead a multi-million dollar project to redevelop the area around the Coliseum BART station.
