Up to 3.3 million homes in California may lose power Monday as part of rolling blackouts to ease pressure on the state's electric grid as a days long heat wave engulfing the West Coast creates an energy shortage, according to the operator of the grid.
The California Independent System Operator says it will likely order utility companies to turn off power starting around 4 p.m. as demand for electricity to cool homes soars during the hottest part of the day beyond the power available in the grid.
California ISO CEO and President Steve Berberich said the state is short about 4,400 megawatts, which equates to about 3.3 million homes, and those affected can expect to lose power for about two hours. He didn't say where the outages might occur, which are up to the state's utilities.
The grid operator ordered the first rolling blackouts in nearly 20 years Friday as unusually hot weather overwhelmed the state's electrical grid. The state's three biggest utilities — Pacific Gas & Electric, Southern California Edison and San Diego Gas & Electric — turned off power to more than 410,000 homes and businesses for about an hour at a time until the emergency declaration ended 3½ hours later.
A second, but shorter, rolling outage came Saturday evening, cutting power to more than 200,000 customers. Californians packed beaches and riverbanks over the weekend to cool off from scorching triple-digit temperatures that raised the risk of more wildfires and fears of the coronavirus spreading.
An irate California Gov. Gavin Newsom signed an emergency proclamation Monday allowing some energy users and utilities to tap backup energy sources as the soaring temperatures forced outages affecting hundreds of thousands of households.
Newsom acknowledged that the state failed to predict and plan for the energy shortages.
"I am not pleased with what's happened," he said during an afternoon press briefing. "You shouldn't be pleased with the moment that we're in in the state of California."
Newsom also sent a letter demanding that the state energy commission, state public utilities commission and the California Independent System Operator investigate broad energy blackouts over two days last week that he said occurred without prior warning or enough time to prepare.
The Democratic governor said residents battling a heat wave and a pandemic in which they're encouraged to stay home as much as possible were left without the basic necessity of electricity.
"These blackouts, which occurred without prior warning or enough time for preparation, are unacceptable and unbefitting of the nation's largest and most innovative state," Newsom wrote. "This cannot stand. California residents and businesses deserve better from their government."
But Berberich said they have warned the state utilities commission of a resource gap.
"We have indicated in filing after filing after filing that the resource adequacy program was broken and needed to be fixed," he said. "The situation we are in could have been avoided."
The state Public Utilities Commission did not respond immediately to a request for comment.
The last time a California governor faced power outages, he was successfully recalled. Gray Davis, a Democrat, was recalled in October 2003 and replaced by Arnold Schwarzenegger, a Republican.
Customers are asked to reduce energy use, especially during peak evening hours, as the hot weather is expected to last through Wednesday night.
California also still faces the threat of power outages to prevent wildfires. Thousands were without power for days last year when Pacific Gas & Electric and other utilities shut off lines amid high, dry winds in order to prevent wildfires.
