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.
Data source: U.S. Energy Information Administration, Preliminary Monthly Electric Generator Inventory, January 2025 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.
Batteries account for 90% of the increase in storage in the Net Zero Emissions by 2050 (NZE) Scenario, rising 14-fold to 1 200 GW by 2030. This includes both utility-scale and behind-the-meter battery storage. Other storage technologies include pumped hydro, compressed air, flywheels and thermal storage.
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.
Global battery storage capacity surpasses hydropower, driven by renewables growth, falling costs, and rising demand for grid flexibility worldwide.
Based on projections, capacity is expected to touch 970 GW by 2030, which is almost 35 times bigger than the 2022. According to BloombergNEF, 2025 alone could see 94 GW of new
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.
Not if: Where & How Much Storage? The worldwide ESS market is predicted to need 585 GW of installed energy storage by 2030. Massive opportunity across every level of the market, from
Table 1. Residential Battery Storage Systems Model Inputs and Assumptions (2022 USD) As with utility-scale BESS, the cost of a residential BESS is a function of both the power capacity and the
The American Clean Power Association reported that the United States added a record 1,602-MW of battery storage capacity in the first quarter of 2025, equivalent to the energy generation
Electrical Energy Storage (EES) systems store electricity and convert it back to electrical energy when needed. 1 Batteries are one of the most common forms of electrical energy storage.
The battery energy storage market continues its rapid growth, reshaping power systems worldwide. After a historic 2025, when global BESS capacity surpassed 250 GW and overtook
The state''s installed BESS capacity is on track to grow over three-fold, from 15.7 gigawatts (GW) in 2025 to a projected 52 GW by 2045, reflecting the technology''s rapid deployment and increasing role in
