Unleashing Flexibility Needs: How Energy Storage Can Make or Break the Case for Renewables
EASE has prepared a position paper on the Renewable Energy Directive Revision (REDIII) highlighting the great opportunity this review offers in terms of speeding up decarbonisation efforts in the energy system: EASE welcomes the 40% renewable energy targets for 2030, but calls for clearer support for energy storage to step up renewables deployment and ensure security of supply.
EASE believes energy storage can be fostered through RED III in multiple ways. Our key points:
Development of a strategy for energy storage, through a sound methodology assessing flexibility and energy shifting needs;
Definition of co-located storage facility and non-discriminatory treatment in tenders for RES plants;
Support the uptake of RES + storage PPAs and ensure non-discriminatory treatment for the issuing of Guarantees of Origin and green certificates;
Ensure full system integration through the proposed art. 20a;
Include energy storage technologies in the efforts to decarbonise the buildings and transport sectors.
Policymakers need to act quickly in view of the urgent need to decarbonise the European energy system: renewables need to be supported by flexibility technologies and through energy shifting, which only energy storage can provide.
In 2025, the energy storage sector experienced significant growth, driven by strong market expansion and evolving EU policy developments. Europe reached the milestone of 100 GW of installed capacity, highlighting the increasing importance of storage in the energy transition.
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.
