California Heat Wave: Rolling Blackouts

LOS ANGELES (AP) — California on Friday ordered rolling power outages for the first time since 2001 as a statewide heat wave strained its electrical system. The California Independent System Operator (California ISO), which manages the power grid, declared an emergency shortly after 6:30 p.m. and directed utilities around the state to shed their power loads. Pacific Gas & Electric, the state’s largest utility, tweeted that it would turn off power to about 200,000 to 250,000 customers in rotating outages for about an hour at a time.
