A draft outlining a ministerial decision to offer investment and operational support for standalone batteries representing a total capacity of 1,000 MW through three auctions has been forwarded by the energy ministry for consultation, running until May 2.

The draft includes all auction details except for the starting price that will be set for the inaugural auction, which the energy ministry aims to stage by the end of June. This first session is planned to offer investment and operational support for standalone batteries representing a capacity of 400 MW, while a second session in the third quarter of the year will offer support for units totaling 300 MW.

The first and second auctions will be open to investors behind prospective projects throughout Greece, while the third auction, planned to take place in the fourth quarter and offer support for standalone batteries with a total capacity of 300 MW, will be open to investors installing such units in the country’s post-lignite areas, namely Kozani and Florina in the north and Megalopoli in the Peloponnese.

Geographical caps will be imposed on the first and second auctions to promote a spread of installations around the country.

Investors will need to have secured energy storage permits to be eligible for taking part in the upcoming auctions, according to the energy ministry’s draft. Also, project capacities cannot exceed 100 MW or be less than 1 MW.

Standalone battery projects that qualify for investment and operational support through the three auctions will need to be launched by December 31, 2025.
