The Hellenic Regulatory Authority for Waste, Energy and Water (RAAEY) published this week the final list of selected projects in the country’s third national energy storage auction.

The list includes nine projects totaling 188.9 MW and 755.6 MWh, with an average awarded bid price of €52,589.1/MW/year.

In total, nearly 800 MW of capacity has been awarded across the three energy storage auctions. The average pricing in the first and second auctions was €49,748/MW and €47,680/MW, respectively.

A total of nine proposals were selected following an evaluation process, reflecting a diverse range of projects in the regions of Western Macedonia and the Peloponnese.

They include developers such as Public Power Corp (PPC), Energiaki Techniki, HELLENiQ Energy, Energy Bankers, and Kiefer, among others. All submitted bids below the cap of €115,000/MW set by the European framework for this type of aid.

Among the selected companies is HELLENiQ RENEWABLES, with two 25 MW projects in Western Macedonia, submitting bids of €43,927/MW/year and €47,913/MW/year, respectively. PPC (Public Power Corp) was awarded a 50 MW facility.

Other selected companies were Amber Energy (18 MW, €54,939/MW/year), Plain Solar (7.9 MW, €58,773/MW/year), Enercoplan (25 MW), Arkadia Storage (10 MW), Heliothema (10 MW), and Ardassa Energy (18 MW).

The total awarded capacity for these nine projects amounts to 188.9 MW, with an average awarded bid of €52,589.16/MW/year. These results mark a significant step forward in integrating storage solutions into the electrical grid.

The selected projects must be operational by the end of April 2026. Awardees are required to submit grid connection applications to the network operator by January 31, 2026, according to the tender rules.

RAAEY also published the list of participants excluded from the auction. The reasons for exclusion vary, including issues related to the assessment of participation documents and the evaluation stage of the financial offers.

It is worth noting that Greece’s Ministry of Environment and Energy recently published a new regulatory framework for granting final connection offers to standalone energy storage facilities (Σ.Α.Η.Ε.). The regulation sets a maximum capacity of 4,700 MW.
