Global installed energy storage capacity by scenario, 2023 and 2030 - Chart and data by the International Energy Agency.
In 2025, capacity growth from battery storage could set a record as we expect 18.2 GW of utility-scale battery storage to be added to the grid. U.S. battery storage already achieved record growth in 2024 when power providers added 10.3 GW of new battery storage capacity.
Global additions of energy storage capacity 2010-2024 Annual gross capacity additions of energy storage worldwide in selected years from 2010 to 2023 (in gigawatt-hours)
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.
All segments face policy challenges in the short term, but are expected to recover to reach 79.8 GW/289.4 GWh cumulative installations. 2025 is set to be another record-breaking year for utility-scale storage, with 22% y-o-y growth.
The global energy storage market added 175.4 GWh of installed capacity in 2024, with the three major regional markets—China, the Americas, and Europe—continuing to account for over 90% of global installations.
As the world transitions to greener sources of power generation such as solar PV and wind, battery energy storage developments will be critical in meeting future energy demand. Global BESS capacity additions expanded 60% in 2022 over the previous year, with total new installations exceeding 43 GWh.
With more than 3.5 GW of capacity added to the grid, battery storage experienced its strongest Q3 on record in 2024 and second strongest quarter overall. Battery storage installations in Q3 2024 were 17% higher than the previous quarter and 58% higher compared to Q3 of 2023.
BACKGROUND increase in investments. According to the ''Net Zero Emissions by 2050'' (NZE) scenario1 of the International Energy Agency (IEA), which is the most referenced scenario with low or no overshoot and limited reliance on negative emissions technologies, yearly investments in the "clean" energy transition must more than double and
In the past five years, annual global additions of energy storage have more than tripled, with estimates suggesting over 25 gigawatts of new capacity added worldwide in the last year alone.3.
