Global battery storage capacity jumps 65.8% to 301.7 GW in 2025
This digest was compiled by AI from multiple sources — links to the originals are below.
Global battery energy storage capacity reached 301.7 gigawatts in 2025, up 65.8% from 182.0 GW in 2024, according to the Energy Institute's 2026 Statistical Review. China accounted for nearly half of the world's total, finishing the year with about 144 GW. The surge is closely tied to the rapid expansion of solar power, which surpassed wind in global electricity generation for the first time in 2025.
Key Facts
- Global battery energy storage capacity reached 301.7 GW in 2025, up from 182.0 GW in 2024, a one-year increase of nearly 120 GW or 65.8%.
- China finished 2025 with about 144 GW of battery storage capacity, accounting for nearly half of the world's total.
- Global installed battery capacity stood at just 1.9 GW in 2015, meaning it increased by a factor of about 158 over ten years, an average annual growth rate of roughly 66%.
- Solar power surpassed wind in global electricity generation for the first time in 2025.
Battery Storage Growth
Global battery energy storage system capacity reached 301.7 gigawatts in 2025, up from 182.0 GW in 2024. That is a one-year increase of nearly 120 GW, or 65.8%. A decade earlier, in 2015, global installed battery capacity stood at just 1.9 GW. Over ten years, capacity increased by a factor of about 158, an average annual growth rate of roughly 66%.
China's Dominance
China finished 2025 with about 144 GW of battery storage capacity. That figure accounts for nearly half of the world's total battery storage capacity. China's lead in battery storage mirrors its dominance in solar, wind, and increasingly nuclear power.
Solar Integration
Solar generation has become cheap enough to deploy at enormous scale, and in 2025 it surpassed wind in global electricity generation for the first time. Battery storage can absorb electricity when generation is abundant and return it to the grid later when electricity is more valuable. That capability helps shift solar production into evening demand periods, reduce curtailment, provide frequency regulation, and smooth short-term fluctuations.
