The EU installed 27GWh of new battery storage capacity in 2025, marking a 45% year-on-year increase and its 12th consecutive record.
SolarPower Europe said utility-scale assets delivered 55% of all new capacity, confirming large-scale projects as the main engine of market growth.
Residential installations fell 6% to 9.8GWh amid lower electricity prices and reduced support schemes, while commercial and industrial systems grew modestly.
Chief executive Walburga Hemetsberger 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,” she added.
The report noted that Europe now operates 77.3GWh of battery storage, up from 7.8GWh in 2021, but must scale to around 750GWh by 2030 to meet energy flexibility needs.
It also highlighted 252GWh of nominal EU battery cell production capacity in 2025, alongside continued gaps in cathode and anode material supply and challenges from high production costs.
Lead author Antonio Arruebo said: “This year’s data shows that the EU storage market is picking up speed again, particularly in large scale systems.”
“At the same time, the decline in distributed batteries reminds us that we still need clearer policy support to unlock more investments for businesses and households,” he stated.
He added that accelerating deployment across all segments will be essential to meeting Europe’s energy transition goals.
