US Adds Record 58 GWh Of Energy Storage Capacity In 2025: Report

The United States (US) installed a record 57.6 gigawatt-hours (GWh) of new energy storage capacity in 2025, marking the largest single year of battery deployment on record, according to a report released by the Solar Energy Industries Association (SEIA) and Benchmark Mineral Intelligence.

Installations rose about 30% from the previous record set in 2024 and are roughly four times the level recorded three years ago, the groups said in the U.S. Energy Storage Market Outlook Q1 2026.

Total installed utility-scale energy storage capacity in the United States reached 137 GWh by the end of 2025. Commercial and industrial systems accounted for 19 GWh, while residential installations stood at 9 GWh.

600 GWh For ESS Installations By 2030

The report forecasts more than 600 GWh of cumulative energy storage installations in the country by 2030, driven by rising power demand, grid reliability needs and cost reductions.

Two-thirds of utility-scale storage capacity added in 2025 was installed in states won by President Donald Trump in the 2024 election, including nine of the top 15 states for new installations. Texas is expected to surpass California in 2026 as the largest U.S. energy storage market.

Standalone storage accounted for nearly 30 GWh of capacity additions in 2025, while systems paired with solar made up around 20 GWh. The residential segment added 3.1 GWh during the year, up 51% from 2024, supported by the expansion of virtual power plant programmes in states including Massachusetts, Texas, Arizona and Illinois.

Increased Production Capacity 

Battery manufacturers also increasingly shifted production capacity from electric-vehicle batteries toward stationary energy storage, the report said. Lithium-ion battery cell manufacturing for stationary storage applications reached more than 21 GWh in 2025, while U.S. facilities have the capacity to produce about 69.4 GWh of battery energy storage systems annually.

Energy storage is expected to play a growing role in balancing electricity supply and demand, particularly as power consumption rises due to data centres and artificial intelligence infrastructure, Benchmark Mineral Intelligence said.
