In 2024, the U.S. reached 26 GW of utility-scale battery storage, adding 10.4 GW that year, reports the US Energy Information Administration. Despite rapid growth, battery storage makes up just 2% of the country’s total electricity capacity. In 2025, operators plan to add a record 19.6 GW of battery storage. They write:
In the United States, cumulative utility-scale battery storage capacity exceeded 26 gigawatts (GW) in 2024, according to our January 2025 Preliminary Monthly Electric Generator Inventory. Generators added 10.4 GW of new battery storage capacity in 2024, the second-largest generating capacity addition after solar. Even though battery storage capacity is growing fast, in 2024 it was only 2% of the 1,230 GW of utility-scale electricity generating capacity in the United States.
In 2025, capacity growth from battery storage could set a record as operators report plans to add 19.6 GW of utility-scale battery storage to the grid, according to our January 2025 preliminary electric generator inventory data.
