Greenvolt Group has secured a financing package from UniCredit comprising EUR 153 million in bridge facilities and a EUR 65 million guarantee facility. The agreement will support project costs associated with the Ełk and Turośń battery energy storage (BESS) projects in Poland, developed by Greenvolt Power.
Located in northeastern Poland, the two projects have a combined capacity of 400 MW / 1.6 GWh (200 MW / 800 MWh each), making them among the largest battery energy storage projects in the country, supporting greater grid flexibility, renewable energy integration and energy security. Turośń Kościelna was officially inaugurated in July 2026, while Ełk is expected to reach commercial operation (COD) in the fourth quarter of the year.
“Energy storage is no longer just an emerging technology – it is a foundational pillar of Europe’s decarbonisation and grid stability. Developing c. 400 MW of BESS capacity in Poland is a landmark achievement, and UniCredit is delighted to support Greenvolt and KKR with a customized €218m financing package, including both a bridge facility and a guarantee facility.
This transaction, which highlights our partnership with Greenvolt across Europe, reinforces our strategic commitment to funding critical green infrastructure and accelerating the green transition, not only in Poland but across CEE.” said Lazar Nikolic, Managing Director, Head of Infrastructure & Export Finance CEE at UniCredit.
The agreement further strengthens the relationship between Greenvolt and UniCredit, building on previous financing transactions supporting the development of utility-scale renewable energy projects across Central and Eastern Europe, including in Poland, Romania and Hungary.
