Five states lead US energy storage expansion to strengthen grid reliability
Reported byCleanTechnica ↗·Sourced by Goodlede
US energy storage capacity has grown from 6,000 MWh in 2020 to over 175,000 MWh today (enough to power 5 million homes for one day on a single charge); California leads with 21,000 MW of capacity and on August 1, 2026 surpassed 13,000 MW of battery discharge for the first time, supplying one-third of the state's peak power demand. Five states—California, Nevada, Massachusetts, New York, and Texas—have enacted policies making energy storage central to grid reliability.
