US Adds 58 GWh of Energy Storage Capacity in 2025

America's energy grid just got a massive upgrade that's bringing cheaper electricity and more reliable power to millions of homes.

The United States added 58 gigawatt-hours of new energy storage capacity in 2025, according to a new report from the Solar Energy Industries Association and Benchmark Mineral Intelligence. That's enough battery power to keep the lights on in Houston from sunset to sunrise.

The total installed storage now includes 137 GWh at the utility scale, 19 GWh for businesses, and 9 GWh for homes. More than 600 GWh of additional storage is expected by 2030, even as Washington debates clean energy policies.

Here's what makes this story remarkable: two-thirds of all new utility storage was built in states won by President Trump. Nine of the top 15 states for new installations lean conservative, and Texas is poised to overtake California as the nation's largest energy storage market in 2026.

"This record-breaking year for energy storage is just the beginning of its rise as a cornerstone of America's energy future," said Darren Van't Hof, interim president of SEIA. The technology lowers consumer costs, makes the grid more reliable, and keeps power flowing during outages.

About half the new storage works alongside solar panels, while the other half operates independently. Both approaches help balance electricity supply and demand, reducing price spikes during peak hours.

The Ripple Effect

The residential storage sector grew 51% in one year, adding 3.1 GWh. Virtual power plant programs in Massachusetts, Texas, Arizona, and Illinois are connecting home batteries into networks that help entire communities manage energy demand and avoid blackouts.

American manufacturing is rising to meet demand. Battery factories originally built for electric vehicles have pivoted to grid storage production. US facilities can now manufacture 69.4 GWh of battery storage systems annually, with 21 GWh of dedicated lithium-ion cell production already online.

The timing couldn't be better. Data centers and AI infrastructure are driving electricity demand to new heights. Energy storage helps the grid scale efficiently without building expensive new power plants that only run during peak hours.

"As policy, manufacturing and market demand align, storage is playing a pivotal role in meeting peak demand, reducing price volatility and improving overall system resilience," said Iola Hughes, head of research at Benchmark Minerals.

The technology works across the political spectrum because it delivers results everyone wants: lower bills, fewer outages, and American-made solutions.
