The weird world of giant batteries

(via The Week) Come 2021, if all goes as planned, Los Angeles will have the biggest battery in the world. It will be made up of 18,000 lithium-ion battery packs — each roughly the size of what you’d find in the Nissan Leaf — with a total capacity of 100 megawatts (MW). That’s enough to power roughly 600,000 homes. This so-called Alamitos battery, being built by AES Energy Storage, is, in many ways, the future.
