EASE and LCP-Delta are pleased to announce the publication of the eighth edition of the European Market Monitor on Energy Storage (EMMES). The Market Monitor is an interactive database that tracks over 3,000 energy storage projects. With information on assets in over 29 countries, it is the largest and most detailed archive of European storage. The database is accompanied by a report which outlines key EU legislation, drivers and barriers for 14 core countries, future projects and forecasts to 2030.

Updated Input Data and Assumptions for the Cost-Benefit Analysis for Limited Energy Reservoirs
The update was requested by CE NRAs to consider recent developments in Frequency Containment Reserves costs and CE power system behaviour. The updated inputs will reflect the most recent frequency data, advancements in Limited Energy Reservoir (LER) technology, and changes in the CE power system. This will ensure a more accurate and up-to-date CBA, leading to a more effective Tmin LER definition that can better maintain steady-state frequency during alert states.
EASE has replied to ENTSO-E consultation on the updated input data and assumptions for the Cost-Benefit Analysis for Limited Energy Reservoirs. EASE stands behind these objectives and believes that a more accurate definition of Tmin LER is essential for the efficient, reliable, and cost-effective operation of energy storage systems.

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.
