Greece is preparing a €200 million battery-storage support programme designed to accelerate deployment of standalone and renewable-linked storage. The plan includes four funding rounds expected before the end of 2026. Each call is expected to have a €50 million budget.
Programme split between self-consumption, standalone and renewable-linked batteries
Half of the overall programme will be directed to storage for self-consumption. The remaining funding is split between standalone batteries and renewable-linked projects, with each category receiving €50 million. The structure is intended to cover different use cases for batteries connected to electricity generation and consumption.
Solar-plus-storage eligibility and auction design for solar-linked batteries
A key eligibility issue concerns solar-plus-storage systems under the Energy Ministry’s approach. Batteries would be eligible if they charge from their associated solar installations rather than from the wider electricity network. This would make Category 11A behind-the-meter batteries supplied exclusively by connected solar generation eligible, alongside Category 11C systems shared by cooperating solar installations. Category 11B systems capable of charging from the grid would be excluded.
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 bidding process. The auction framework applies specifically to the solar-linked portion of the programme.
Standalone allocation and potential pipeline scale under priority grid connection
Competition for the standalone-storage allocation could be substantially stronger than for other segments. Authorities are considering allowing all projects covered by Greece’s priority grid-connection procedure to participate in the auction. If adopted, that approach could open participation to a pipeline of up to 4.7 GW.
Batteries for companies and municipalities, linked to Apollo programme objectives
The two remaining funding rounds will focus on batteries used for self-consumption by companies and municipalities. Municipal storage is also 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 share of locally generated renewable electricity rather than exporting it when production exceeds immediate demand.
The programme is being developed as storage shifts from a grid-support technology toward a central element of renewable investment economics. Greece’s large solar pipeline is increasingly producing periods of low daytime prices followed by steep evening ramps. That pattern is described as strengthening both the commercial value and system value of batteries within the market context referenced in the plan.
