“Those batteries play a pivotal role in California’s electric grid, partially replacing fossil fuels in the evening. Between 7 p.m. and 10 p.m. on April 30, for example, batteries supplied more than one-fifth of California’s electricity and, for a few minutes, pumped out 7,046 megawatts of electricity, akin to the output from seven large nuclear reactors.
Across the country, power companies are increasingly using giant batteries the size of shipping containers to address renewable energy’s biggest weakness: the fact that the wind and sun aren’t always available.
Over the past three years, battery storage capacity on the nation’s grids has grown tenfold, to 16,000 megawatts. This year, it is expected to nearly double again, with the biggest growth in Texas, California and Arizona.”
