Battery Storage Begins to Find a Home at Some Water Utilities

High-capacity batteries aren’t just making electric vehicles viable. They’re also beginning to transform water utilities. In Southern California, a number of water utilities have begun to install large batteries alongside their pumping plants and water treatment facilities. The idea is to store energy in the batteries overnight, when energy is cheaper. Then during the daytime, when power is more expensive, a water agency can tap that battery power for its routine operations.
