News, Op-Ed: California’s giant new batteries kept the lights on during the heat wave : detailed suggestions and opinions about Op-Ed: California’s giant new batteries kept the lights on during the heat wave .
California just stared down its most extreme September heat event in history and survived better than expected — thanks in part to a new system of huge, grid-connected batteries.
The severity and duration of this latest climate-driven heat tested the state’s electricity grid like never before, setting records for power demand that pushed the supply to its limits. But the system held. The lights stayed on.
Additional tests lie ahead, for California and other states and nations. But after this round, California has a clear lesson for the world: Battery storage is a powerful tool for grids facing new strains from heat, cold, fire, flood or aging networks. And just as important, batteries are key to the zero-carbon future we need to avoid even greater stresses down the line.
Californians delivered big time this month when asked to cut use at critical moments during the crisis. But without storage capacity from new battery systems, reducing demand might not have been enough, and many consumers would have faced painful outages.
