Pacific Gas and Electric said it may cut off power to 2.5 million people in northern California on Saturday to reduce the risk of wildfires during severe winds. Thirty-six counties would be affected by the utility’s deliberate blackout—possibly its biggest to date—which could last 48 hours, the San Francisco Chronicle reported. The move comes as PG&E admits it may have caused the Kincade fire, which is still roaring across an area the size of Manhattan and has destroyed dozens of buildings.
