EMMES 2.0 - June 2018
EASE and Delta-ee are pleased to announce the publication of the second edition of the European Market Monitor on Energy Storage (EMMES).
EMMES 2.0 shows that:
The electrical energy storage capacity annually installed grew by 49% between 2016 and 2017 in Europe, which is a steady growth rate since 2015. In 2018it is expected to grow at a similar rate (45%) with the level of new installations accelerating
The total installed base in Europe (excluding pumped hydro) reached 1.6 GWh at end of 2017
Germany and UK remain the most important markets for grid scale projects
Italy is emerging as a rapidly growing market for residential electrical energy storage but Germany remains a clear leader.
On 5 June 2018, EASE published a study estimating the energy storage capacity that would be needed in order for the different EU Member States to achieve its decarbonisation targets.
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.
