The European Union is placing battery storage at the centre of its energy strategy as growing amounts of
solar and wind power are being curtailed because electricity grids cannot absorb the surplus.

Under a new agreement reached in June, the European Commission, 22 member states, energy
companies, industries and financial institutions have committed to expanding storage capacity. The EU
currently has around 55 GW of storage but may require approximately 200 GW by 2030.
The agreement aims to deliver at least 30 to 35 GW of additional storage by 2028. Commercial and
industrial battery capacity is expected to rise from 9 GWh in 2026 to 24 GWh by 2028, while battery-
backed power purchase agreements are also expected to expand.
Battery costs fell by around 93% between 2010 and 2024, while Europe installed a record 21.9 GWh of
new battery systems in 2024. Supporters say greater storage deployment could reduce renewable-
energy curtailment, lower grid congestion and decrease dependence on imported gas.
However, development continues to be slowed by grid-connection delays, unclear regulations, double
network charges and Europe’s dependence on imported battery cells and critical raw materials. Industry
groups are now calling for a dedicated EU battery-storage action plan to accelerate deployment and
close the gap before 2030.
