Battery / Grid Storage
Two countries hold nearly three-quarters of the world’s installed capacity.
Global battery storage additions hit a record 108 GW in 2025, up 40% year over year. China and the U.S. together hold 74.6% of installed global capacity.
Standings
About 60% of global battery storage additions in 2025 (167 GWh), with another 203.5 GWh expected in 2026.
Added 19 GW in 2025, up ~60% year-over-year — the fastest growth rate of the two leaders, even with China’s much larger total volume.
Utility-scale additions more than doubled to about 4.6 GW even as total additions dipped slightly from 2024 — a real structural shift toward grid-scale systems, from a smaller base.
