Our energy company DTEK has published Sustainability in Action 2025, a detailed account of its sustainability approach, progress and commitments. During the year DTEK expanded the Tyligulska Wind Power Plant towards 500 MW, delivered Ukraine's largest battery energy storage system at 200 MW, and launched RISE with Octopus Energy Group. The report also sets out DTEK's first Energy Transition Plan, with targets to cut emissions and phase out coal by the end of 2035. We invite readers to explore the full publication.
What does Sustainability in Action 2025 cover?
The publication covers DTEK's environmental, social and governance action during 2025, with content accurate up to the end of March 2026. It presents the company's first Energy Transition Plan, which commits DTEK to reducing scope 1 and 2 emissions by 42% and scope 3 emissions by 25% by 2035 against a 2023 baseline, and to reaching net zero by 2050.
How is DTEK expanding renewable generation in Ukraine?
Construction began in 2025 on the second phase of the Tyligulska Wind Power Plant, Ukraine's largest wind project, built with Danish turbine manufacturer Vestas. The phase adds 64 turbines and increases capacity more than fourfold, from 114 MW to 500 MW. Completion is due in 2026, with enough supply for 900,000 Ukrainian homes. DTEK also advanced plans for the 650 MW Poltavska wind farm. Installed renewable generation capacity reached 923 MW.
What is a BESS and why does it matter for Ukraine?
A BESS is a battery energy storage system: it stores electricity and releases it when the power system needs it, which helps balance the grid. In 2025 DTEK Renewables delivered Ukraine's largest, adding 200 MW of storage across six sites in the Kyiv and Dnipropetrovsk regions with technology provider Fluence. The facilities can supply 600,000 homes for up to two hours. Construction took six months and total investment was €125 million.
What is RISE and who is the international partner?
RISE, or Resilient Independent Solar Energy, is Ukraine's first large-scale programme dedicated to decentralised energy systems. It was launched with international partner Octopus Energy Group and aims to mobilise up to €100 million over five years for commercial solar and battery systems in businesses and public sector institutions.
How does DTEK support its people?
More than 5,700 DTEK employees have served in the Armed Forces of Ukraine since the start of russia's full-scale invasion, with almost 4,000 on active duty as of March 2026. In 2025 DTEK developed ProVeteran, which supports employees from mobilisation through to their return to civilian and professional life. To date, 1,100 enlisted employees have returned to civilian life and more than 500 veterans have completed retraining.
What is the message from DTEK's leadership?
Maxim Timchenko, Chief Executive Officer of DTEK, said: "DTEK is not waiting for the war to end before building a more secure future. We are investing in wind power, battery storage, distributed generation and smart grids today, while continuing to maintain critical supply across the country."
That approach reflects the strategy of our shareholder Rinat Akhmetov. As russia steps up its attacks on our companies, they continue to invest in Ukraine's sustainable future.
