The completed project in Chortkiv is the first solar energy project implemented by Nefco to support critical infrastructure in Ukraine. The solar power plants were officially commissioned on 23 September 2025 with all involved project partners present in the city. Читати історію українською мовою. Ukraine had more than 9 GW of installed solar PV capacity prior to the Russian Federation's full-scale invasion in 2022. Most of the capacity was from distributed installations. In 2025, SSK significantly strengthened its position in the market by implementing more than 220 MW of solar power plants across Ukraine. These include primarily ground-mounted solar farms as well as several industrial rooftop projects for self-consumption — solutions that help businesses reduce. The Ukrainian company SOLARsk has completed the construction of the country's first solar power plant built on the basis of a domestically produced tracker system — HSAT HORIZON STR-111. This initiative comes at a critical time, as the nation works to diversify its energy sources.

Ukrainian private utility DTEK has energised the largest battery storage project in the war-torn country and one of the biggest ones in Eastern Europe. The 200 MW/400 MWh installation spans six sites ranging from 20 MW to 50 MW and connected to the power grid in the Kyiv and Dnipropetrovsk regions. From ESS News DTEK and Fluence have begun commissioning Ukraine's largest battery energy storage system, a 200 MW/400 MWh installation spread. North America leads with 40% market share, driven by streamlined permitting processes and tax incentives that reduce total project costs by 15-25%. Europe follows closely with 32% market share, where standardized container designs have cut installation timelines by 60% compared to traditional. Together, they are building a 200 MW / 400 MWh battery energy storage system just outside Kyiv - a project scheduled to go commercial in October 2025 and poised to reshape how Ukraine balances its grid. Its containerized structure ensures rapid deployment, offering a cost-effective and eco-friendly renewable energy alternative.
