Business Case and Taxonomy of Behind-the-Meter Battery Energy Storage Systems in Europe
Behind-the-meter (BtM) Battery Energy Storage Systems (BESS) are pivotal in the European Union's pursuit of ambitious climate goals and renewable energy integration. Co-located with technologies like solar photovoltaics (PV), they empower consumers and contribute to peak-shaving and load management. However, realizing their full potential necessitates a clear regulatory framework.
As BtM BESS deployment continues to expand, addressing existing barriers is imperative. These challenges include among others fair remuneration, net metering, complex tax structures, and inadequate integration of energy storage in system planning.
By addressing these challenges and providing the necessary policy support, the European Union can fully leverage BtM BESS and BtM BESS+PV solutions. This approach not only promotes a sustainable and resilient energy system but also empowers consumers to actively participate 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.
In this position paper, the Energy Storage Europe Association calls for a shift from today’s “first-come, first-served” queue system to a more efficient, strategic, and transparent framework that recognises the unique value of energy storage for reducing congestion, enhancing flexibility, and making better use of existing grid infrastructure.
