Infrastructure investor Actis has entered the Polish energy storage market with the acquisition of two large-scale projects from DTEK’s DRI, while R.Power and Solax have announced project updates in the country.
Actis has acquired a 112MW/518MWh ready-to-build (RTB) battery energy storage system (BESS) project in Kozienice and has signed for a 132MW/623MWh project in Trzebinia, a deal which will complete once it is operational.
The projects totalling a combined 244MW/1,141MWh are being bought from DRI, part of Ukraine-based energy investor DTEK.
Both have 17-year capacity market (CM) contracts won in 2022 with obligations starting in 2027. The CM is the bedrock of the business case for large-scale storage in Poland. Actis said that there is also strong corporate PPA demand in Poland, and the country’s transition away from goal to renewables and gas offers strong opportunities for storage.

DRI itself was not the developer or CM bidder of the projects, having acquired them in 2024/25. It bought the Kozienice project from independent power producer (IPP) Greenvolt Group last year and the Trzebinia project from developer Columbus Energy the year before.
It is therefore slightly unusual to see DTEK/DRI now selling on the projects to Actis after putting in the work to secure financing, supply and offtake for them, but it’s not unheard of. The companies didn’t reveal the terms or stake size of the acquisition.
Actis announced the deal on Tuesday (6 October), as Solar Media’s Energy Storage Summit Central and Eastern Europe (CEE) 2026 kicked off in Warsaw, Poland.
Jaroslava Korpanec, head of CEE at Actis, commented: “The CEE region has historically been underinvested in, and the need to drive decarbonisation and invest in independent energy supply is, in our view, absolutely crucial. Poland is a major European power market but a carbon-intensive one that needs to transition from coal to renewables while keeping the grid steady.”
Project updates from R.Power and Solax
IPP R.Power and inverter and BESS firm Solax have also provided project updates in Poland this week.
R.Power announced that all 64 BESS units and 32 medium-voltage transformers have been installed at its 150MW/300MWh Jedwabno BESS, with grid connection planned for December 2026. It secured project finance earlier this year for the project, which also has a CM contract and has power firm Axpo as offtaker as well.
Solax meanwhile announced separate partnerships with engineering firms Rova Systems and and EPC firm Rawicom, for BESS deployments in Poland.
The first project via the Rova partnership is a 10MW/20MWh project for an unnamed investor, including black-start capabilities. It announced the partnerships at the Energy Storage Summit CEE 2026 event, pictured below.
