Battery storage in the US fleet
The United States has 614 battery storage plants with a combined nameplate capacity of 37.6 gigawatts as of August 2026. Battery storage accounts for 2.7% of all US generating capacity. These facilities shift power in time rather than generating it — the figures here describe what the equipment could produce running flat out, not what it generated.
Battery storage is concentrated in the South and West. Texas and California together hold two-thirds of US battery storage capacity; just two states hold half of it nationally. Texas alone operates 226 plants totaling 15,517 megawatts, or 41.3% of the national fleet. California comes next with 9,530 megawatts across 142 plants. Thirty-six states have at least some battery storage capacity. Arizona ranks third with 4,260 megawatts, followed by Nevada, Oklahoma, and New Mexico.
The largest battery storage facility is Skeleton Creek Energy Center Hybrid in Oklahoma at 752 megawatts, which came online in 2020. Menifee Power Bank in California follows at 680 megawatts, brought online in 2024. Other major plants include McGrau Ford Battery Storage Facility in Georgia at 530 megawatts, Manatee Solar Energy Center in Florida at 484 megawatts, and Catclaw Solar in Arizona at 450 megawatts. Battery storage is a young technology: the oldest plant still listed is Bonny Eagle in Maine, which first came online in January 1910, while the newest is McGrau Ford, which came online in August 2026.
