EU Battery Storage Installations Surge in 2025 Led by Utility-Scale Growth
The European Union's energy storage sector experienced unprecedented growth in 2025, installing 27.1 GWh of new battery capacity. This represents a remarkable 45% increase compared to 2024, bringing the total operational battery capacity across the bloc to 77.3 GWh. To put this into perspective, the current capacity is ten times the 7.8 GWh recorded in 2021.
Utility-Scale Dominance
A significant milestone was reached in 2025 as utility-scale battery systems connected directly to the grid accounted for over 55% of all new installed capacity. Conversely, the residential storage segment experienced a 6% decline, dropping to 9.8 GWh. This downturn in home batteries was primarily driven by lower electricity prices and a reduction in public subsidies across several member states.
For the first time, utility-scale battery systems contributed more than half of all installed capacity in the EU, signaling a major shift in market dynamics.
Top Performing Member States
Germany maintained its leadership position in new battery capacity deployments, largely due to massive utility-scale projects. Meanwhile, Spain successfully entered the top five by accelerating its storage deployment, supported by regulatory improvements that recognize storage as a strategic asset. Italy, Bulgaria, and the Netherlands also secured spots in the top five. Collectively, these top five countries accounted for 63% of all new capacity installed in the EU last year.
Manufacturing Challenges
Despite strong deployment numbers, Europe's battery manufacturing capacity remains heavily skewed. While the continent boasts a solid industrial base with 252 GWh of nominal cell manufacturing capacity in 2025, approximately 92% of this is dedicated to electric vehicle batteries. This highlights a critical need to strengthen and diversify the local supply chain specifically for stationary energy storage applications.
