Greece is preparing a €200 million battery-storage support programme aimed at accelerating deployment of standalone and renewable-linked storage. Four funding rounds are expected before the end of 2026. The scheme is structured around separate allocations for self-consumption, standalone batteries, and renewable-linked projects.
Each funding call is expected to have a €50 million budget. Half of the overall programme will target batteries for self-consumption, while standalone batteries and renewable-linked projects each receive €50 million. The design includes specific eligibility rules for solar-plus-storage systems.
Eligibility rules for solar-plus-storage
The Energy Ministry plans to support batteries that charge from their associated solar installations rather than from the wider electricity network. Under the planned approach, Category 11A behind-the-meter batteries supplied exclusively by connected solar generation would be eligible. Category 11C systems shared by cooperating solar installations would also qualify.
Category 11B systems capable of charging from the grid would be excluded from support. For qualifying solar-linked batteries, the €50 million allocation will be distributed via a competitive auction. Projects seeking lower subsidies are expected to receive an advantage in that process.
Auction scope for standalone storage
Competition for the standalone-storage allocation could be substantially stronger than for other parts of the programme. Authorities are considering allowing all projects covered by Greece’s priority grid-connection procedure to participate. If adopted, that could expand the auction pipeline to as much as 4.7 GW.
Batteries for companies and municipalities
The two remaining funding rounds will focus on batteries used for self-consumption by companies and municipalities. Municipal storage is also linked with Greece’s Apollo programme, which aims to reduce electricity costs for vulnerable consumers and public-sector facilities through renewable generation. Batteries could enable municipalities to consume a larger share of locally generated renewable electricity rather than exporting it when production exceeds immediate demand.
The programme is being prepared as storage shifts from a grid-support technology toward a central component of renewable investment economics. Greece’s large solar pipeline is increasingly associated with periods of low daytime prices followed by steep evening ramps. That pattern is described as strengthening the commercial as well as system value of batteries.
