The Irvine Water District and Michelson Capital announced the completion of the nation’s largest behind-the-meter energy storage project at the Irvine Ranch Water District’s (IRWD) Michelson Water Recycling Plant. The new 2.5MW/15MWh installation is a part of a distributed network of 11 energy storage installations at the water district’s recycling and pumping facilities that together total 7MW/34MWh. The new installation will store power when it is cheap, which the facility can use during peak hours when power is more expensive.
