PG&E has begun cutting power across parts of Northern California. Nearly 800,000 customers will be affected
California's largest utility has intentionally cut power to roughly 500,000 customers in Northern California -- a number that's scheduled to rise later Wednesday -- as the company tries to prevent wildfires during extremely windy and dry conditions. Pacific Gas & Electric started the shutoff early Wednesday, just after midnight, leaving parts of 22 counties -- including northern portions of the San Francisco Bay Area -- in the dark.
