Nearly 800,000 homes were left without electricity and heating on Thursday morning following a Russian overnight attack targeting energy infrastructure, the country’s acting energy minister stated, as power teams worked quickly to restore service.

Artem Nekrasov noted in remarks posted on the Ukrainian Energy Ministry’s official Telegram channel that the Dnipro and Zaporizhzhia regions were nearly entirely without power after the Russian strike.

“Repair efforts are underway to restore power to consumers as quickly as possible,” Nekrasov said.

Power has since been reconnected in the Zaporizhzhia region, though hundreds of thousands of homes in Dnipro still lack electricity and heating.

Ukrainian officials advised residents to reduce the use of high-power electrical devices to avoid new outages while repairs are ongoing.

Nekrasov added that the attack also left parts of several other regions without power, including Chernihiv, Kyiv, Ivano-Frankivsk, and Zakarpattia.

The power outages are taking place amid freezing temperatures in Kyiv, where forecasts predict overnight lows under 20 degrees.

“There is absolutely no military rationale behind such strikes on the energy sector and infrastructure that leave people without electricity and heating in winter,” Ukrainian President Volodymyr Zelenskyy stated on X on Thursday.

“This is Russia’s war directly targeting our people and life in Ukraine – an attempt to crush Ukraine.”

The strikes occurred just days after Ukrainian President Volodymyr Zelenskyy met with U.S. special envoy Steve Witkoff and former President Donald Trump’s son-in-law Jared Kushner to discuss ongoing diplomatic efforts to end Russia’s nearly four-year war in Ukraine.

Zelenskyy noted that the discussions centered on security guarantees, monitoring a possible ceasefire, and Ukraine’s reconstruction as part of a wider peace framework.
