According to the International Energy Agency, global battery energy storage systems stood at about 28 GW in 2022, then shot up with 69 GW added in 2024, showing the fastest growth phase so far. 3 terawatts of utility-scale capacity by fuel, region, and ownership. The largest fuel source is natural gas, accounting for just under 43% of. . Global electricity output is set to grow by 50 percent by mid-century, relative to 2022 levels. With renewable sources expected to account for the largest share of electricity generation worldwide in the coming decades, energy storage will play a significant role in maintaining the balance between. . These systems have 50-60 year lifetimes and operational efficiencies of 70-85%. Hydrogen electrolysers are not included.

Nearly 11,000 MW of energy storage were added in 2024 to supplement generation capacity, increasing the total MW of energy storage 62% within the last year and 181% in the last two years. 15,306 MW of additional energy storage under preparation, testing, or construction are projected to come online in 2025.
Data on renewable power capacity represents the maximum net generating capacity of power plants and other installations that use renewable energy sources to produce electricity. For most countries and technologies, the data reflects the capacity installed and connected at the end of the calendar year.
According to the U.S. Energy Information Administration (EIA), in 2010, seven battery storage systems accounted for only 59 megawatts (MW) of power capacity—the maximum amount of power output a battery can provide in any instant—in the United States. By 2015, 49 systems accounted for 351 MW of power capacity.
Additionally, 15,306 MW of energy storage are scheduled to come online in 2025. The largest share of capacity slated to come online in 2025 is from solar facilities (74%). Wind capacity makes up the next largest portion of projected new capacity in 2025 at 18%, and natural gas makes up 7%.

This is a list of energy storage power plants worldwide, other than pumped hydro storage. Many individual plants augment by capturing excess electrical energy during periods of low demand and storing it in other forms until needed on an . The energy is later converted back to its electrical form and returned to the grid as needed.
