There is now 9.8GWh of large-scale BESS online in the UK, according to the latest data from Solar Media Market Research’s ‘Battery Storage: UK Pipeline & Completed Assets Database’ report.

China continues to dominate BESS deployments globally with 4.3GW/11.2GWh of deployments in May, including a 1GWh flow battery system.

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.

A total of 10.9GWh of grid-scale BESS entered commercial operations in March, up 29% year-on-year and 3% month-on-month. 

The UK saw 1,590MW/3,179MWh of grid-scale BESS projects approved last month, bringing the total approved projects to around 55.4GW/117GWh.

February 2025 saw around 4.5GW/10.5GWh of grid-scale BESS deployments globally, with China continuing to account for the majority but Europe increasing its share from January.
