State Aid for Electricity Storage in Europe
National support schemes, public funding, planned capacity and supported technologies
European governments are committing substantial public resources to electricity storage as renewable generation expands and power systems require greater flexibility. The national schemes, however, differ significantly in scale, technologies, funding instruments and expected storage capacity.

Executive Brief
Electricity storage has become a significant recipient of public support across the European Union. Since 2022, a growing number of Member States have notified schemes to the European Commission to accelerate investment in batteries and other forms of electricity storage.
The measures differ substantially. Some provide direct investment grants. Others combine investment support with operating aid or use competitive procurement mechanisms to secure storage capacity over several years. Some schemes are explicitly limited to battery systems, while others are technology-neutral or designed to accommodate longer-duration storage.
Italy represents by far the largest single scheme identified in the eBriefing, with an estimated budget of €17.7 billion. Other major measures include Hungary's €1.1 billion programme, Bulgaria's €603 million RESTORE investment, Spain's €350 million scheme and Greece's €341 million programme.
More recent measures in Romania and Slovenia confirm that public support continues to expand. But headline budgets alone do not provide a complete picture: authorised aid, actual expenditure, MW, MWh, storage duration and implementation status are not reported consistently across national programmes.
