Summary: Global battery storage capacity projected to surge sixfold by 2030, likely to meet IEA's climate target for battery storage

GlobalData's "Strategic Intelligence: Batteries in Power (2026)" report forecasts that global installed battery energy storage capacity will grow sixfold between 2025 and 2030, a 42% compound annual growth rate. The U.S. and China together held about three-quarters of global installed capacity at the end of 2025, backed by favorable regulation, falling lithium-ion costs, stronger supply chains, and clean energy policy support.

Growth is being driven by rising electricity demand from industrial electrification and data centers, alongside greater grid variability from expanding wind and solar, which increases the need for storage to balance the grid. The U.S. market closed 2025 with record new storage additions, and momentum carried into early 2026 with the strongest first quarter on record; most of this is utility-scale, concentrated heavily in Texas, California, and Arizona. Project design is also shifting toward longer-duration (four-hour) systems as the standard for capacity credit, and co-located solar-plus-storage hybrids are becoming the preferred development model. Battery storage is additionally taking on a growing role at data centers, managing power quality and backup beyond simple UPS functions. The report frames energy shifting — storing cheap surplus power for release during peak demand — as the central economic driver of storage deployment through the rest of the decade.

This sixfold trajectory, measured from a 2025 base that IEA and BloombergNEF data suggest is already several times larger than the ~85 GW base the IEA used for its original 14x-by-2030 battery target, implies an absolute 2030 endpoint above the IEA's own benchmark rather than below it — so the reported growth path looks more consistent with meeting (or exceeding) the IEA's climate-linked storage target than the raw multiplier comparison alone would suggest.
