PG&E Corp. said late Monday it started cutting power in parts of Northern California to reduce wildfire risks, a day after the state narrowly averted rolling blackouts to relieve strain on its electric grid during a heat wave.

The San Francisco-based utility, which serves 16 million people in Northern and Central California, said the outages will affect about 172,000 customers in 22 counties, stretching from wine country to the Sierra foothills.
