Greenvolt Power sweeps Polish capacity auction with 1.2 GW win

Greenvolt Power dominated the December 2023 Polish capacity auction, securing 1.2 GW for six wholly owned Battery Energy Storage (BESS) projects. This accounts for over 70% of the total BESS capacity awarded and comes with a 17-year capacity payment obligation, the maximum tenure in Poland’s capacity market mechanism. Participating through Polskie Sieci Elektroenergetyczne S.A. (PSE), Poland’s transmission grid operator, Greenvolt’s 1.4 GW total grid-secured capacity makes it the largest BESS portfolio to clear an auction in Poland.
