SACRAMENTO — California regulators say the state is unlikely to experience electricity shortages this summer after securing new power sources and a wet winter that filled the state’s reservoirs enough to restart hydroelectric power plants that were dormant during the drought.
The nation’s most populous state normally has more than enough electricity to power the homes and businesses of more than 39 million people. But the electrical grid has trouble when it gets really hot and everyone turns on their air conditioners at the same time.
It got so hot in August 2020 that California’s power grid was overwhelmed, prompting the state’s three largest utility companies to shut off electricity for hundreds of thousands of homes for a few hours over two consecutive days. Similar heat waves in 2021 and 2022 pushed the state to the brink again. State officials avoided blackouts by encouraging people to conserve energy and tapping some emergency gas-powered generators.
The state’s electrical grid was strained in part because of a severe drought that left reservoirs at dangerously low levels, leaving little water available to pass through hydroelectric power plants. The water level in Lake Oroville got so low in 2021 state officials had to shut down a hydroelectric power plant that was capable of powering 80,000 homes.
That won’t be a problem this year after winter storms dumped massive amounts of rain and snow on the state. Plus, an additional 8,594 megawatts of power from wind, solar and battery storage will come online by Sept. 1, according to Neil Millar, vice president of Transmission Planning & Infrastructure Development for the California Independent System Operator.
One megawatt of electricity is enough to power about 750 homes.
“I am relieved to say that we are in a much better position than what we were going into 2022,” said Siva Gunda, vice chair of the California Energy Commission.
The struggle to power the state during severe heat waves has been a problem for Democratic Gov. Gavin Newsom, who has aggressively moved the state away from fossil fuels. California gets much of its power now from sources like wind and solar. But those power sources are not always available.
To avoid blackouts during heat waves, Newsom and the state Legislature spent $3.3 billion to create a “strategic reliability reserve.” State officials used the money to extend the life of some gas-fired power plants that were scheduled to retire and to purchase large diesel-powered generators. Last September, when a severe heat wave pushed the statewide demand for electricity to an all-time high, this reserve generated up to 1,416 megawatts of energy.
