California’s Independent System Operator (CAISO) issued a Flex Alert Sunday, asking Californians to slash power consumption to prevent rolling blackouts. CAISO said Sunday looks set to be the “most challenging” of the Labor Day weekend heatwave baking the state.

The power grid operator stated that excessive heat throughout the western United States and wildfires threatening power lines were the reason for the Flex Alert, and reminded Californians that “every watt counts” in the battle to prevent rolling blackouts across much of California.
