EASE and Delta-ee are pleased to announce the publication of the third edition of the European Market Monitor on Energy Storage (EMMES).
EMMES 3.0 shows that:
Market growth in 2018 exceeded expectations, and was higher than both 2016 and 2017
A key factor in this rapid market growth during 2018 was the commissioning of new front-of-the meter projects in the UK
Behind-the-meter markets continue to develop positively across Europe, with growing opportunities for energy storage in C&I and residential applications in Central & Eastern Europe, Spain and the Nordics.
Political negotiations on the “Clean Energy for All Europeans” package (CEP) were concluded in December 2018, and the new electricity market design should be enacted into Member States national legislation over the next 18 months. This promises to deliver important changes that could have a significant and positive impact on the energy storage market in Europe.
While the market is forecast to grow in 2019 and 2020, it will do so at a lower rate due to the short-term saturation of some front-of-the-meter markets, and the maturing of the large German residential market.
However, new growth drivers will emerge as the CEP is enacted and we expect E-mobility to become a significant new application for stationary energy storage.
EASE responds to the European Commission’s Public Consultation on the European Grids Package, calling for clearer guidance and obligations on flexibility assessments in planning processes. This includes common methodologies, improved DSO-TSO coordination, and enhanced grid connection procedures. Storage should be considered a standard resource for grid services and reflected accordingly in system planning, cost-benefit analyses, and network development scenarios.
The European Commission has recently launched a stakeholder consultation on its upcoming guidance regarding grid connections in situations where capacity constraints exist. In response, EASE urged reforms to tackle stalled “ghost” projects blocking viable energy storage. Key recommendations include a “first-ready, first-served” model, transparent grid data, and more flexible rules to accelerate the clean energy transition.
On 27 May 2025, over 200 participants attended the webinar on the "EASE Guidelines on Safety Best Practices for Battery Energy Storage Systems". The Guidelines are designed to support the safe deployment of outdoor, utility-scale lithium-ion (Li-ion) BESS across Europe.
Energy storage is a key enabler of the European Union’s decarbonisation and energy security objectives, yet current grid fee structures often act as barriers to its deployment. This position paper outlines critical challenges related to network tariffs and charges that create market distortions and discourage much-needed investments in flexibility.
