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 2024, the United States saw a significant increase in cumulative utility-scale battery storage capacity, which surpassed 26 gigawatts (GW). This growth was marked by the addition of 10.4 GW of new battery storage, making it the second-largest capacity addition after solar energy. Despite this rapid expansion, battery storage still represented only 2% of the total 1,230 GW of utility-scale electricity generating capacity in the country.

Looking ahead to 2025, projections indicate that battery storage capacity could reach new heights, with plans to add an impressive 19.6 GW to the grid. It's important to note that battery storage systems do not generate electricity themselves; rather, they store electricity produced by other generators or the power grid, functioning as secondary sources of electricity.
