Russia conducted one of its largest attacks on Ukraine's energy infrastructure in months overnight into Wednesday, striking power plants, substations, and related facilities primarily around Kyiv.

Ukrainian officials described the assault as the heaviest combined strike on energy sites since spring. It involved nearly 190 drones and ballistic missiles, according to President Volodymyr Zelenskyy. Ukraine's air force reported intercepting five missiles and 155 drones.

At least five people were killed across the country, including a child in the Kyiv region, with additional injuries reported. Prime Minister Serhiy Koretskyi said the attack affected 11 regions, damaging residential buildings, social infrastructure, civilian enterprises, and railways in addition to energy targets.

Power outages hit Kyiv and surrounding areas, as well as parts of Dnipropetrovsk, Donetsk, Sumy, and Kharkiv regions. Ukraine's largest private energy firm DTEK restored electricity to 8,000 homes in the capital following what it called a difficult night. Emergency power cuts were imposed in Kyiv and three surrounding regions, the first such measure in the capital since spring.

Russia's defense ministry confirmed the strikes, stating it targeted the Trypilska thermal power plant, the Kyiv hydroelectric power plant in Vyshhorod, a power substation, an energy storage facility, and a data center in Kyiv. Moscow claimed these sites supported Ukraine's military-industrial sector and defense facilities.

Zelenskyy noted strikes on critical infrastructure in Zhytomyr, Mykolaiv, Kirovohrad, and Rivne regions as well. Repair crews worked through the morning to restore services, though some households remained without power into Wednesday.

The attack follows days of intensified drone activity over Kyiv and comes as Ukraine prepares for winter, when energy shortages have previously led to widespread blackouts and heating disruptions. Officials have warned of further Russian pressure on the grid in the coming months.
