According to the U.S. Energy Storage Market Outlook Q1 2026 released by the Solar Energy Industries Association (SEIA) and Benchmark Mineral Intelligence, as of 2025, 137 GWh of utility scale storage has been installed in the United States. 19 GWh of commercial and industrial (C&I) storage has been installed and 9 GWh of residential storage has been installed.
Despite actions in Washington targeting clean energy, over 600 GWh of energy storage is expected to be installed by 2030. This rapid deployment will help lower energy costs, enhance reliability, and boost American energy independence.
Two-thirds of all utility scale energy storage capacity installed in 2025 was built in states won by President Donald Trump, including 9 of the top 15 states for new installations. Texas is set to overtake California in 2026 as the largest energy storage market in the country.
“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 and CEO of the Solar Energy Industries Association. “Whether it’s paired with solar or standing on its own, energy storage lowers consumer costs, makes the grid more reliable, and keeps the power on in homes during outages.”
Standalone storage made up nearly 30 GWh of new capacity added in 2025, while storage paired with solar accounted for 20 GWh. The residential energy storage sector added 3.1 GWh in 2025, marking a 51% year over year increase. Expansion of virtual power plant programs in states like Massachusetts, Texas, Arizona, and Illinois are driving residential storage deployment, which helps states cut costs, manage peak demand, and strengthen grid resilience.
In 2025, battery cell manufacturers pivoted from EV manufacturing towards dedicated energy storage production, converting existing lines and changing future plans. As of 2025, lithium-ion battery cell manufacturing for stationary electricity storage applications has risen to over 21 GWh according to SEIA’s Solar and Storage Supply Chain Dashboard, which is enough to power the city of Houston from sunset to sunrise. And American manufacturing facilities now have the capacity to manufacture 69.4 GWh of battery energy storage systems.
“The US energy storage market has entered a new phase of sustained, high volume-deployments,” said Iola Hughes, Head of Research at Benchmark Minerals. “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. At a time of rising electricity demand, driven in part by the growth of data centers and AI infrastructure, energy storage will be critical to ensuring the grid can scale reliably and efficiently.”
The quarterly ESMO report tracks the various battery chemistries such as lithium-ion, sodium-ion, zinc-base, metal air and flow batteries, as well as energy storage duration data.
