Figures

This page presents data and charts on energy storage in Europe, including battery energy storage systems (BESS), electrochemical storage, and pumped hydro storage. It provides insights into installed energy storage capacity (GW and GWh), market size, and growth forecasts to 2030. As of the beginning of 2026, Europe has 100 GW of installed capacity, projected to exceed 215 GW by 2030, with an additional 128 GW / 300 GWh of electrochemical (battery) storage expected to be deployed.

The figures show cumulative capacity by technology, energy storage growth trends, and deployment by country across Europe, including front-of-the-meter (FoM) and behind-the-meter (BtM) storage. Battery storage (BESS) is the fastest-growing segment, while pumped hydro storage remains the largest contributor to total installed capacity.
