DRI, the EU renewables arm of Ukrainian energy company DTEK, has acquired rights to build a battery energy storage system (BESS) in Kozienice, located in the east-central part of Poland.
The 112MW/448MWh project was acquired from Greenvolt Group, a company within KKR’s portfolio.
Through Greenvolt Power, a European developer of utility-scale wind, solar, and energy storage projects, the BESS is at the Ready-to-Build (RTB) stage, with all necessary administrative approvals, permits, and grid connection agreements in place for immediate construction.
According to DRI, the Kozienice project will progressively strengthen Ukraine’s grid as the country’s energy network is integrated into a single European system.
Said DRI CEO, Murat Cinar, in a release: “With the signing of this agreement, we are consolidating our position in the Polish energy market, and more broadly, in Europe’s energy transition.”

The acquisition follows selection by DRI days prior of Fluence Energy B.V. for the 133MW Trzebinia project in southern Poland.
Cinar continued: “By adding a second battery storage project to our portfolio, the acquisition of the Kozienice BESS will increase our total storage capacity available to the Polish grid to 245MW.
“This technology will play a vital role in Europe’s transition towards a renewables-based system, enhancing grid stability and reducing the risk of outages during periods of system stress. Battery energy storage systems will be at the heart of the power grid of the future”
Said CEO of the Greenvolt Group, João Manso Neto: “Greenvolt is one of the largest developers of energy storage in Europe, a technology that stands as a key pillar of the energy transition. This agreement fully aligns with our strategic objective to deliver high-impact projects that drive the ongoing transformation of the European energy landscape and attract strong market interest.”
Greenvolt says the sale is aligned with the Group’s asset rotation strategy. The company says they have an approach of rotating approximately 70–80% of the assets developed internally while retaining 20–30% on its balance sheet — with over €500 million ($586 million) in disposals completed this year.
Alongside its two battery storage projects in Poland, DRI is also advancing a further 15 solar and onshore wind projects at various stages of development in Croatia, Italy and Romania.
Greenvolt Power has a project portfolio totalling 13.2GW across 18 countries, of which over 4.3GW are BESS projects. In Poland, Greenvolt is developing assets with a total capacity of over 4.3GW, including 731MW of wind power, 1,878MW of solar power, and 2,712MW of storage capacity.
