Greece is preparing a €200 million battery-storage support programme with four funding rounds expected before the end of 2026. The initiative is designed to accelerate deployment of standalone and renewable-linked storage. Each funding call is expected to have a €50 million budget.
Half of the programme will be directed to batteries for self-consumption. The remaining half is split between standalone batteries and renewable-linked projects, with each receiving €50 million. The Energy Ministry’s eligibility rules focus on how batteries are charged in solar-plus-storage configurations.
Eligibility for solar-plus-storage and auction design
The ministry plans to support batteries that charge from their associated solar installations rather than from the wider electricity network. Under the proposed 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 eligibility. For the €50 million allocation covering qualifying solar-linked batteries, distribution is planned via a competitive auction. Projects seeking lower subsidies are expected to receive an advantage in that auction.
Standalone and self-consumption rounds, including municipal storage links
Authorities expect competition for the standalone-storage allocation could be substantially stronger. They are considering allowing all projects covered by Greece’s priority grid-connection procedure to participate, which could broaden the auction pipeline to as much as 4.7 GW. Two further funding rounds will focus on batteries used for self-consumption by companies and municipalities.
Municipal storage is linked with Greece’s Apollo programme, which targets reduced 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 instead of exporting it when production exceeds immediate demand.
The programme is being prepared as battery storage shifts from a grid-support technology toward a component of renewable investment economics. Greece’s large solar pipeline is increasingly associated with low daytime prices followed by steep evening ramps, which supports the commercial and system value of batteries.
