EU Battery Storage Installations Reach 27.1 GWh in 2025 Led by Utility-Scale Growth

The EU battery storage market recorded its twelfth consecutive year of growth in 2025, with newly installed capacity reaching 27.1 GWh. This represented a year-on-year increase of approximately 45%, setting a new annual record for energy storage deployment across the European Union.

Utility-scale battery storage emerged as the primary driver of growth, accounting for around 55% of all new installations. Improved market conditions and strengthened policy frameworks enabled large-scale projects to reach record deployment levels.

Since 2021, the EU’s total installed battery storage capacity has expanded tenfold, rising from 7.8 GWh to approximately 77.3 GWh by the end of 2025. Meeting projected energy flexibility requirements by 2030 will require a further tenfold increase, pushing total capacity toward an estimated 750 GWh.

The year 2025 is widely regarded as a turning point for Europe’s battery storage sector, marking the transition from distributed and residential systems toward grid-scale infrastructure as the dominant growth engine.

Battery storage is increasingly recognized as a critical enabler of renewable energy integration, supporting grid stability, reducing curtailment, and enhancing system resilience as wind and solar penetration continues to rise across the region.
