EASE and Delta-ee are pleased to announce the publication of the fourth edition of the European Market Monitor on Energy Storage (EMMES).
EMMES 4.0 shows that:
The European energy storage market contracted in 2019 to 1 GWh, with a cumulative installed base of 3.4 GWh across all segments.
In 2019 saturated FCR markets in the UK and Germany slowed growth in the Front of Meter segment. We expect a rebound in 2020 as the demand for system flexibility rises and value streams open.
The residential segment continues to grow steadily, driven by growth in Germany that accounted for 76% of the annual market in 2019.
The C&I segment saw a small contraction in the leading markets (Germany and the UK) in 2019. Regulatory uncertainty and long payback periods are hindering growth.
However, the future of energy storage in 2020 in Europe remains positive as the energy transition progresses.
Regulators and grid operators are increasingly recognising the value that storage adds to electricity systems. Consumers in both the residential and C&I segments show growing interest in storage as technology costs fall and Feed in Tariffs are phased out. And the storage industry continues to innovate around products and propositions.
The EU’s Clean Energy Package is already opening doors for storage, and this process will only accelerate over the coming years as regulations stabilise.
Energy Storage Europe has prepared a reply to the European Commission's public consultation on TYNDP 2026 Identification of System Needs Methodology. The European Commission’s public consultation seeks feedback on the analytical framework used by ENTSO-E to identify cost-efficient and technically robust opportunities for the development of Europe’s electricity system, without prescribing specific investment decisions.
In 2025, the energy storage sector experienced significant growth, driven by strong market expansion and evolving EU policy developments. Europe reached the milestone of 100 GW of installed capacity, highlighting the increasing importance of storage in the energy transition.
Energy Storage Europe replies to the European Commission’s public consultation on the Battery Booster Facility. On 16 December 2025, the European Commission announced a Battery Booster Strategy, within the Automotive Action Plan. The Strategy includes a Facility of EUR 1.5 billion in the form of loans for projects in the production of battery cells in Europe.
Energy Storage Europe's position paper, "Ensuring System Stability in Europe: The Role of Energy Storage in Providing Inertia", focuses on how the EU can implement a cost-effective and technologically neutral approach to procuring inertia. It also outlines how such an approach can be firmly embedded within a harmonised European methodology for assessing and monitoring inertia needs across synchronous areas.
