What happened

DTEK said Russia carried out a massive attack on one of its thermal power plants, severely damaging equipment and forcing the plant to halt electricity generation entirely; the company did not name the plant or disclose its location for operational security. No casualties were reported at the plant itself. DTEK said it would coordinate repair work with grid operator Ukrenergo once conditions allowed. The company noted its thermal power plants have now been struck more than 230 times since Russia's 2022 full-scale invasion began; a June 2026 attack on a DTEK thermal plant killed engineer Oleksandr Kosolapov, and this strike came a day after a separate drone attack killed a worker at a DTEK coal mine in Dnipropetrovsk region, recorded separately on this map.
