Market development and deployment
By 2025, global grid battery power capacity was 267 GW with 610 GWh energy capacity, compared to the other major form of grid storage, pumped-storage hydroelectricity with 200 GW power and 9000 GWh energy storage worldwide as of 2025 according to International Hydropower Association. The battery market had thus surpassed the power generation capacity of pumped-storage, but remained far smaller in terms of energy capacity.
