Global installed storage capacity is forecast to expand by 56% in the next five years to reach over 270 GW by 2026. The main driver is the increasing need for system flexibility and storage
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
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
The utility-scale market led the way, setting a record with 4.9 GW installed in Q2, enough capacity to power 3.7 million American homes during average peak demand.
This includes bioenergy, geothermal, hydropower (excluding pumped storage), solar, wind, and marine energy. Solar (total): Total solar (on- and off-grid) electricity installed capacity,
According to the report 5.3GW/14.5GWh of storage was installed in Q3 2025 in the US, pushing 2025 year-to-date installations past 2024 capacity. Image: Wood Mackenzie According to
