Greece is preparing a €200 million battery-storage support programme designed to accelerate deployment of standalone and renewable-linked storage. Four funding rounds are expected before the end of 2026, with each call budgeted at €50 million. The scheme will include support for batteries used for self-consumption and for projects linked to renewable generation.
Programme structure and funding allocation
Half of the overall programme will target storage for self-consumption. Standalone batteries and renewable-linked projects will each receive €50 million. The Energy Ministry’s approach also addresses how solar-plus-storage systems are treated under eligibility rules.
The ministry plans to support batteries that charge from their associated solar installations rather than from the wider electricity network. This would make Category 11A behind-the-meter batteries eligible when supplied exclusively by connected solar generation. Category 11C systems shared by cooperating solar installations would also be eligible, while Category 11B systems capable of charging from the grid would be excluded.
Auction design for solar-linked and standalone capacity
The €50 million allocation for qualifying solar-linked batteries will be distributed through a competitive auction. Projects seeking lower subsidies are expected to receive an advantage in the auction process. Authorities are also considering how to broaden participation for the standalone-storage call.
Competition for the standalone-storage allocation could be substantially stronger. Greece is considering allowing all projects covered by its priority grid-connection procedure to participate, which could open the auction to a pipeline of up to 4.7 GW. The remaining rounds focus on batteries used for self-consumption by companies and municipalities.
Batteries for companies and municipalities, including Apollo link
The two remaining funding rounds will support self-consumption battery use by companies and municipalities. Municipal storage is connected 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 portion of locally generated renewable electricity rather than exporting it when production exceeds immediate demand.
The programme is being developed as storage increasingly functions as a central component of renewable investment economics. Greece’s large solar pipeline is creating periods of low daytime prices followed by steep evening ramps, strengthening the commercial and system value of batteries.
