Grenergy has secured capacity contracts for five stand-alone storage projects totalling 534MW and 2100MWh in Poland’s latest auction run by Polskie Sieci Elektroenergetyczne.
The company said the awarded assets – named Fred, George, Lucius, Hagrid and Harry – will provide reserve capacity when minimum system levels are not guaranteed.
According to Grenergy, the awards represent more than 11% of the total storage capacity offered in the auction.
From January 2030, the services will receive a fixed price of PLN465.02/kW per year indexed to CPI for 17 years, giving the company a minimum allocation of more than €132 million.
Grenergy added that capacity payments form part of the revenue stack alongside energy trading and participation in other regulated markets.
The developer has also secured a PLN34 million grant of about €8 million for four further stand-alone projects of 136MWh expected online before 2028.
The company said it now has a 5GWh stand-alone pipeline in Poland and a 31GWh pipeline under its European Greenbox platform.
