Sept. 10, 2025. (Bohdan Nazarenko/DTEK) Ukraine’s biggest private energy firm, DTEK, has launched a major battery storage facility that will bring power to hundreds of thousands of homes and strengthen the grid ahead of expected Russian attacks this winter, the company said.
The €140 million total investment aims to enhance power grid stability, bolstering Ukraine’s energy security and independence. The project will be the biggest operational energy storage portfolio in Eastern Europe at the time of commissioning.
Together, they will store up to 400 MWh of electricity – enough to supply two hours of power to 600,000 homes (equivalent to roughly half the households in Kyiv).
"Despite the war, we invest in Ukraine’s recovery and growth. Our energy sector, having withstood countless Russian attacks, now gains new momentum," owner of DTEK and Ukraine’s richest man, Rinat Akhmetov, said in a press release.
The batteries are spread out across six undisclosed locations in Ukraine, which helps de-risk the projects from Russian attacks compared to a centralized system, Julian Jansen, managing director covering southern and eastern Europe at Fluence, said during the briefing.
