European Market Outlook for Battery EU solar Storage 2025
By recognising storage systems under EU funding mechanisms and grid planning processes, the EU can unlock their full potential, not only in stabilising energy supply and maximising
Germany, Italy and the United Kingdom continue to lead the European battery storage market in 2025 and together account for almost 70 percent of newly installed annual capacity. Germany holds the largest market share with 27 percent, followed by Italy with 17 percent and the UK with 11 percent.
Despite positive market developments, SolarPower Europe stresses that the European battery storage market needs to grow at an even faster rate to meet the rising demand for grid flexibility. A potential total volume of up to 400 GWh is projected for 2029 – an ambitious but necessary target for the energy transition.
In 2024, Europe¹ installed 21.9 GWh of battery energy storage systems (BESS), marking the eleventh year of record-breaking annual additions since 2013, when our records began. The latest additions take the total running European battery fleet to 61.1 GWh at the end of 2024.
Narrowing the scope to the European Union (EU), 18.5 GWh of BESS were installed across the bloc in 2024, equivalent to 85% of existing installations on the continent. As consequence, EU total operating battery storage capacity reached 49.1 GWh at the end of 2024.
