The Long and Short of It: Long Duration Energy Storage for Europe’s Future
On 15 September 2022, EASE together with Long Duration Energy Storage (LDES) Council co-organised a webinar "The Long and Short of It: Long Duration Energy Storage for Europe’s Future" to discuss long duration energy storage for Europe’s future.
Experts from the LDES Council and EASE presented the most recent reports, storage targets, and learnings of companies based in Europe who are leading the way for long duration energy storage.
Panellists discussed their viewpoints on Europe’s clean energy future and how storage provides flexibility and stability both with renewable energy sources and without.
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.
