Global energy storage capacity is set to smash records in 2025, enabling deeper integration of renewables and reshaping energy markets worldwide.
Record Growth in Storage Installations
Worldwide energy storage additions — excluding pumped hydropower — are forecast to hit 92 GW (247 GWh) in 2025, up about 23 % from 2024. China is expected to account for over half of this growth, followed by the U.S. and major European markets.
Storage Enables Renewables to Penetrate Grids
As solar and wind generation expand, storage becomes key to balancing variable supply and demand. Renewable generation in the first half of 2025 grew by +31 % for solar and +7.7 % for wind, outpacing overall electricity demand growth. This growth is propelling energy markets beyond fossil-fuel dominance.
Policy & Market Shifts Drive Investment
Governments and utilities are awarding large-scale contracts to storage and grid-forming battery projects. According to industry reports, the transition now depends not just on generation capacity but on system flexibility and resilience.
Outlook: From Infrastructure Build-Out to Market Transformation
Analysts say this storage boom will reshape global energy markets by 2030: demand peaks, new trade of electricity and services across borders, and business models evolve from selling MWh to delivering system services.
