New battery capacity of 27.1 GWh was installed across the EU in 2025, with over half (55 per cent) coming from utility-scale systems, confirming large-scale storage as the main engine of market growth.

The new record year of installations, according to SolarPower Europe’s EU Battery Storage Market Review 2025, marks a 45 per cent year-on-year growth, expanding the battery fleet tenfold since 2021 to 77.3GWh.

Conversely, residential installations declined by 6 per cent, reflecting continued slowdown driven by lower electricity prices and reduced support schemes.

On the manufacturing side, EU battery manufacturing reached 252GWh of nominal cell production capacity, but persistent gaps remained in cathode and anode material supply limit expansion, and over 90 per cent of existing cell capacity is geared toward electric vehicles rather than stationary storage.

To meet its energy flexibility needs by 2030, the EU must now repeat its tenfold increase, scaling to around 750GWh by the end of the decade.

Walburga Hemetsberger, CEO of SolarPower Europe, said: “Europe’s battery storage market is growing fast and delivering the flexible capacity our energy system urgently needs. The strong uptake of utility-scale batteries in 2025 shows investors are ready, the technology is mature, and the system benefits are clear. But we must now dramatically accelerate deployment. To support EU security and competitiveness, we need a battery fleet capable of supporting a fully flexible, renewable based energy system.”
