Texas Is About To Overtake California In Battery Storage

Record Installations in 2025

U.S. battery storage installations hit a record 57.6 GWh in 2025. According to the U.S. Energy Storage Market Outlook Q1 2026 from the Solar Energy Industries Association (SEIA) and Benchmark Mineral Intelligence, installations are now four times higher than totals from just three years ago. The United States had a total of 137 GWh of utility‑scale storage installed as of 2025, plus 19 GWh of commercial and industrial systems and 9 GWh of residential storage.

Analysts expect the growth streak to continue, projecting more than 600 GWh of energy storage to be deployed nationwide by 2030, even as the administration targets clean‑energy industries.

Texas Projected to Surpass California

Two‑thirds of utility‑scale storage installed in 2025 was built in red states, including nine of the top 15 states for new installations. Texas is projected to overtake California as the nation’s largest battery‑storage market in 2026.

• Standalone battery projects accounted for nearly 30 GWh of new capacity in 2025.
• Solar‑plus‑storage installations contributed about 20 GWh.
• Residential storage deployments reached 3.1 GWh, a 51 % increase year‑over‑year.

Analysts say virtual power‑plant programs in states such as Massachusetts, Texas, Arizona, and Illinois are helping drive adoption by reducing costs and easing strain during peak‑demand periods.

Shifting Supply Chain

The supply chain is adapting to support the boom. In 2025, several battery‑cell manufacturers pivoted production from EV batteries to dedicated stationary‑storage cells, converting existing lines and adjusting future plans. Lithium‑ion cell manufacturing for stationary storage reached more than 21 GWh in 2025—enough to power Houston overnight, according to SEIA’s Solar and Storage Supply Chain Dashboard.

U.S. factories now have the capacity to manufacture 69.4 GWh of battery energy‑storage systems annually.
