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 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.
This position paper, prepared by the Energy Storage Europe Association, assesses the system value of long-duration energy storage, identifies barriers to deployment, and proposes recommendations to better align European energy, industrial, and financing frameworks with the long-term flexibility needs of a fully decarbonised power system.
In this position paper, the Energy Storage Europe Association calls for a shift from today’s “first-come, first-served” queue system to a more efficient, strategic, and transparent framework that recognises the unique value of energy storage for reducing congestion, enhancing flexibility, and making better use of existing grid infrastructure.
