In 2025, Europe surpassed 100 GW of installed storage capacity for the first time, and by Q2 2026 storage overtook nuclear as a source of installed power capacity. With electrochemical storage forecast to grow by a further 153 GW by 2030, energy storage is becoming a core pillar of Europe's future electricity system.
June 2026 / Market Analyses
EMMES 10 - June 2026
Europe set to hit 100 GW of energy storage, with more than 115% growth expected by 2030.
The 10 edition of the European Market Monitor on Energy Storage (EMMES) by the Energy Storage Europe and LCP Delta, is now available. Europe added a record 13.5 GW / 26.4 GWh of electrochemical storage in 2025, surpassing 100 GW of installed storage capacity across all technologies. While deployment continues to accelerate, significant opportunities remain across every European market as electrification and renewable energy continue to expand.
Key findings from EMMES 10
Europe added a record 13.5 GW / 26.4 GWh of electrochemical storage in 2025, bringing total installed capacity to 102.7 GW across all technologies
For the first time, energy storage has overtaken nuclear capacity in Europe, while the number of operating reactors continues to decline
Despite record deployment, no European country has yet reached its full storage potential
Forecasts for utility-scale batteries have been revised upward by 25% compared with last year's outlook
By 2030, an additional 153 GW / 485 GWh of electrochemical storage is expected to be added to European grids
Behind-the-meter storage reached 30.2 GW / 46.2 GWh, driven by solar-plus-storage, dynamic tariffs and electrification
Front-of-the-meter storage reached 18.5 GW / 34.4 GWh, with strong momentum in Great Britain, Italy, Poland and Belgium
In 2025, total installed storage capacity reached 102.7 GW across different technologies.
Energy storage has overtaken nuclear capacity, while the number of operating nuclear reactors has been steadily declining. The shutdown of nuclear plants in Germany has been the biggest contributor to this, removing around 11 GW of capacity, while Great Britain and Belgium have also decommissioned a significant number of reactors since 2016.
Compared with last year's outlook, EMMES 10 raises expectations for utility-scale battery deployment by 25%, reflecting stronger market fundamentals, growing project pipelines and increasing confidence in the role of storage within Europe's future energy system.
Behind-the-meter storage has been key to this progress, with 30.2 GW / 46.2 GWh of electrochemical capacity installed by the end of 2025, led by Germany, Italy, the Netherlands, Austria and Great Britain. Growth is being driven by solar-plus-storage adoption, the rollout of dynamic electricity tariffs, increasing electrification of homes and businesses, and participation in flexibility markets.
Front-of-the-meter battery storage has also expanded, reaching 18.5 GW / 34.4 GWh by the end of 2025. Momentum has been significant in countries with established capacity markets, including Great Britain, Italy, Poland and Belgium, as well as those with dedicated large-scale storage support schemes, such as Italy, Bulgaria, Poland and Spain

Thermal Energy Storage can help European industry decarbonise, reduce costs, and access new revenue streams. Yet significant regulatory, economic, and financial barriers continue to limit its deployment.
Energy Storage Europe welcomes the proposal for an Industrial Accelerator Act (IAA) and supports its overall objective of strengthening industrial capacity, accelerating decarbonisation, and creating stronger lead markets for strategic clean technologies in the European Union.
