The UK market saw strong interest and activity in 2025 but now appears to be shifting from a development market to one focused on execution, writes Solar Media analyst Charlotte Gisbourne.

The UK grid-scale battery storage market grew 45% in 2025, with 4GWh coming online during the year, bringing total operational capacity to 12.9GWh.

With Document No. 136 scrapping the mandatory energy storage allocation requirement for renewable energy and the rollout of policies governing new energy storage, China’s energy storage market is going through a period of dynamic change.

China again dominated global battery storage deployments in August, accounting for two-thirds of what came online, but Europe, North America and Oceania/Australia had good months too.

The UK had its busiest month of the year so far in July for large-scale BESS project planning consents, with over 5GW/10GWh approved.

Activity in the UK battery energy storage system (BESS) market continues to grow substantially year-on-year despite numerous headwinds, as detailed in this H1 recap from our Market Research colleagues.

A pinch under 6GWh of grid-scale BESS was approved for construction in the UK last month, bringing the total with planning consent to nearly 130GWh.

Chile, China and Australia drove global BESS deployments in April, a month which saw nearly 9GWh of grid-scale capacity enter commercial operations.
