Actis, the sustainable infrastructure investor, has acquired a 112MW, 518MWh battery energy storage project in Kozienice, Poland, from DRI, the renewables arm of Ukraine’s DTEK group. It has also signed an agreement to acquire a 132MW, 623MWh project in Trzebinia, with completion expected once that project becomes operational. The Kozienice project is ready for construction.
Together the two projects total 244MW and 1,141MWh, with storage durations above four hours. Both hold 17-year inflation-indexed capacity market contracts, the revenue underpin that lets an infrastructure fund buy development-stage storage rather than waiting for operating assets.
Poland’s system need is the investment case. The country is expected to retire roughly 18GW of coal-fired capacity and add 50GW of renewables and 14GW of gas by 2040, and Actis is working toward a 1.5GW wind, solar and storage target for Central and Eastern Europe. Long-duration storage contracted into the capacity market is how that transition gets financed at infrastructure, rather than venture, cost of capital.
The purchases continue a busy Polish storage market: in September, ENGIE’s Polish subsidiary acquired a vehicle developing a 438MW, 876MWh project. Mercom’s data put first-half 2026 battery project acquisition activity at about 14GW across 63 transactions globally, more than double the pace of a year earlier.
