## Summary

Grid-scale [Battery Storage](/ja/entity/battery-storage) deployment hit records into 2026, and [China](/ja/entity/china) is dominant.
China commissioned 66.43GW/189.48GWh of new-type storage in 2025 (+52% power, +73% energy YoY) and
installed 18GW/65GWh in December 2025 alone, more than the [US](/ja/entity/united-states) added all year. The
world added 275.3GWh in 2025 (+61%) and is set to add ~353GWh in 2026, with China expected to
contribute ~203.5GWh and the US ~49GWh. In February 2026 China led with ~53% of global additions.
China aims for cumulative installs equal to today's entire global capacity by 2027. The buildout
soaks up [Renewables](/ja/entity/renewables) [curtailment](/ja/n/renewables-curtailment-record-2026) and firms the grid.

## By the numbers

- 66.43 GW / 189.48 GWh, China's 2025 new-type storage commissioned.
- 18 GW / 65 GWh, China's December 2025 installs (> full-year US).
- 275.3 GWh, global storage added in 2025 (+61% YoY).
- ~353 GWh, projected global additions in 2026.
- ~49 GWh vs ~203.5 GWh, projected 2026 US vs China additions.

## Why it matters

Storage is the hinge that lets renewable-heavy grids shift midday solar into peak hours and cut
curtailment. China's command of manufacturing and deployment compounds its battery and solar
dominance, and widens a strategic gap as the US storage market grows but stays an order of
magnitude smaller.

## What to watch

- US deployment under shifting tariffs and tax-credit policy.
- China's progress toward its 2027 cumulative-capacity target.
- Whether storage materially cuts CAISO/Texas curtailment and negative prices.
