Europe's operational battery fleet has passed the 100 GWh mark for the first time, after a record 36 GWh of new storage came online in 2025 — annual growth of about 48%, reports pv Europe.
Utility-scale takes the lead
For the first time, utility-scale projects accounted for more than half of Europe's new installations in 2025, overtaking the home-battery segment that led the market for years. The drivers: grid operators need flexibility as solar and wind shares climb, negative midday prices reward shifting energy into the evening, and revenue stacking — arbitrage, ancillary services, capacity payments — has made big batteries bankable.
The road to 2030
Industry analyses put Europe's near-term grid-scale pipeline at around 122 GW. SolarPower Europe's European Battery Market Outlook projects a cumulative fleet of roughly 582 GWh by 2030 in its medium scenario — still short of the ~600 GWh the EU needs to hit its climate and energy-security targets, which keeps policy support and grid-connection reform firmly in the spotlight.
Why it matters for solar companies
Storage is no longer a niche add-on: it is becoming the default companion to PV in tenders, C&I projects and residential offers alike. Installers and EPCs that can deliver hybrid solar-plus-storage are winning work that pure-PV players lose. Find energy storage companies worldwide or see our roundup of storage companies by country.
