Ukrainian energy group DTEK has agreed to sell two utility-scale battery energy storage system (BESS) projects in Poland. The agreement with international investment firm Actis was signed by DRI, the group's European renewable energy development arm. The financial terms of the transaction have not been disclosed.
One of the projects is located in Kozienice and involves a battery storage system with a power capacity of 112 MW and an energy storage capacity of 518 MWh. The project is already ready to build and has been acquired by Actis. The second project is located in Trzebinia, with a power capacity of 132 MW and a storage capacity of 623 MWh. Its sale has been agreed upon, but the transaction is expected to close following the project's commissioning.
Together, the two projects will have a combined power capacity of 244 MW and an energy storage capacity of 1,141 MWh. Utility-scale battery storage systems enable electricity to be stored during periods of excess generation or lower prices and supplied to the grid when demand increases. These solutions help stabilize power systems and improve the integration of renewable energy sources.
Both projects have secured 17-year capacity market contracts in Poland, awarded in 2022. Payments under the contracts are scheduled to begin in 2027 and will be indexed to inflation.
Actis, the buyer of the projects, invests in energy and other infrastructure assets, with a focus on sustainable development. Since October 2024, the company has been part of the General Atlantic investment platform.
DRI operates across European markets, including Poland, Romania, Croatia, and Italy. Energy storage development also remains a key priority for DTEK in Ukraine. In September 2025, the group, together with Fluence, commissioned battery energy storage facilities in Ukraine with a combined capacity of 200 MW, representing an investment of €125 million.
