California heat spurs 1st rolling power outages since 2011
LOS ANGELES — California on Friday ordered rolling power outages for the first time since 2011 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 until around 11 p.m. Other utilities were told to do the same.
“Extreme heat is really the driver behind this,” said Anne Gonzales, spokeswoman for the power grid operator.
