Longtime Slashdot reader Uncle_Meataxe shares a report from the Sacramento Bee: California’s power grid handled a nearly three week long record-setting heat wave with few issues. The heat wave was the hottest 20-day period on record around Sacramento and set an all-time temperature record of 124 degrees in Palm Springs. Emergency alerts and calls for voluntary conservation were avoided this time around. Officials credit years of investment in renewable energy, especially battery storage that store solar power for use when the sun stops shining.
CAISO last issued calls for voluntary conservation two years ago, during a 2022 bout of extreme heat. Since then, roughly 11,600 megawatts of new renewable energy sources have come onto California’s electricity grid. That includes 10,000 megawatts of battery power, enough to power 10 million homes for a few hours. California is now home to the most grid batteries in the world outside of China, [said Elliot Mainzer, president and CEO of California Independent System Operator (CAISO)].
“Batteries performed very well in this event, they were charged and ready at the right times for optimization on the grid,” he added. “That made a big, big difference.” […] Apart from battery storage, Mainzer also credited that success to less extreme temperatures in Southern California as well as noticeable slightly lower electricity consumption in the peak demand hours, from 4 p.m. to 9 p.m.
