CMS advises lending consortium on ECA-backed project financing for 132MW battery energy storage system in Poland
CMS has advised a consortium of lenders, made up of Erste Bank Polska S.A., UniCredit S.p.A. and PKO Bank Polski S.A., on the project financing for a 132MW 4-hour lithium-ion battery energy storage system (BESS) in the Trzebinia district, Małopolskie region, Poland, with total commitments of approximately PLN 470m. The term facility benefits from an export credit agency (ECA) guarantee issued by KUKE S.A., backed by the Polish State Treasury, under the ETI (energy transformation investment) programme.
This milestone project finance transaction represents one of the first and largest standalone battery energy storage financings closed in Poland, underpinning the country's energy transition by supporting grid stability and the integration of renewable energy sources. The project holds a capacity agreement secured through Poland’s capacity market auction, which ensures long-term revenue visibility. The project is expected to become operational in early 2027.
CMS provided end-to-end transactional support to the lending consortium, including preparing and negotiating the finance documentation and conducting a legal due diligence across regulatory, project document and real estate workstreams.
The CMS team was led by Katarzyna Mazur and Kacper Stanosz, and included Jukub Wieczorek, Maciej Lorenz, Bartosz Potrykus, Michał Kuzel, Adrian Horne and Katarzyna Lesińska (Banking & Finance); and Łukasz Szatkowski, Karolina Tatomir, Dominika Paczena, Jan Michaluk, Anna Jarecka and Klaudia Jaczewska (Energy & Infrastructure).
