US energy storage set a new record in Q1 2025
US energy storage set a Q1 record in 2025 with 2 GW added, but looming policy changes could put that growth at serious risk.
Together, solar and battery storage account for 81% of the expected total capacity additions, with solar making up over 50% of the increase. Solar. In 2024, generators added a record 30 GW of utility-scale solar to the U.S. grid, accounting for 61% of capacity additions last year.
Battery energy storage capacity meanwhile is undergoing unprecedented growth. A record 10.3 GW of grid-scale storage was added in 2024, and this record is expected to be smashed in 2025. The EIA expects 18.2 GW of utility-scale battery storage capacity installations in 2025.
The report also notes that the US commissioned 11.9GW of battery energy storage system (BESS) capacity last year, a 55% increase from the previous year, the fifth consecutive year of record-breaking additions. That is across all segments including grid-scale, commercial & industrial (C&I) and residential.
Energy storage systems, mostly large batteries, are important because they help store solar and wind power for use when the sun isn't shining or the wind isn't blowing. In 2025, over 31 GW of new storage capacity is expected to be built. California and Texas are the leaders in battery storage.
