California regulators say the state is unlikely to run out of electricity this summer due to a large surge in energy storage and a wet winter that filled the state’s reservoirs enough to restart hydroelectric plants that were idle during the drought . Normally the country’s most populous state has more than enough electricity to power the homes and businesses of more than 39 million people. But the power grid has problems when it gets really hot and everyone turns on their air conditioners at the same time. In August 2020, things got so hot that California’s power grid became overwhelmed, forcing the state’s three largest utilities to cut power to hundreds of thousands of homes for a few hours over two consecutive days. Similar heat waves in 2021 and 2022 again pushed the state to the brink. State officials prevented blackouts by encouraging people to conserve energy and tapping some emergency gas generators. The state’s power grid was partially strained due to a severe drought that left reservoirs at dangerously low levels, leaving little water available to flow through hydroelectric power stations. . Water levels in Lake Oroville became so low by 2021 that government officials had to shut down a hydroelectric plant that could power 80,000 homes. That won’t be a problem this year after winter storms dump massive amounts of rain and snow on the state. In addition, an additional 8,594 megawatts of energy 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 households. “I am relieved to say that we are in a much better position than where we went in 2022,” said Siva Gunda, Vice Chairman of the California Energy Commission. The struggle to power the state during severe heat waves has been a problem for Democratic Gov. Gavin Newsom, which has aggressively weaned the state off fossil fuels. California now gets much of its power from sources such as wind and solar. But those power sources are not always available. To avoid power outages during heat waves, Newsom and the state legislature spent $3.3 billion to create a “strategic reliability reserve.” would retire and buy large diesel generators. Last September, when a severe heat wave sent electricity demand to an all-time high statewide, this reserve generated up to 1,416 megawatts of energy. But it also goes against the state’s goal of having 100% clean energy by 2045. The state obtained 59% of its energy from non-fossil sources in 2021, up from a high of 64% in 2019. the drought reduced the amount of hydroelectric power available. One way to use solar energy is to store it during the day and use it at night.

The reserve helps keep the lights on. But it also goes against the state’s goal of having 100% clean energy by 2045. The state will get 59% of its energy from non-fossil sources in 2021, up from a high of 64% in 2019. State officials say the drop is mainly because the drought reduced the amount of available hydropower.

“I would say people shouldn’t be surprised to see a flex warning,” said Alice Reynolds, president of the California Public Utilities Commission. “I mean, we’re talking about extreme heat, unusual events that are hard to control.”
