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.

Explore the benefits of joining Energy Storage Europe
In 2025, Europe surpassed 100 GW of installed storage capacity for the first time, and by Q2 2026 storage overtook nuclear as a source of installed power capacity. With electrochemical storage forecast to grow by a further 153 GW by 2030, energy storage is becoming a core pillar of Europe's future electricity system.

Thermal Energy Storage can help European industry decarbonise, reduce costs, and access new revenue streams. Yet significant regulatory, economic, and financial barriers continue to limit its deployment.
Energy Storage Europe welcomes the proposal for an Industrial Accelerator Act (IAA) and supports its overall objective of strengthening industrial capacity, accelerating decarbonisation, and creating stronger lead markets for strategic clean technologies in the European Union.
