Russia destroyed all thermal power plants and almost all hydroelectric capacity in Ukraine, President Volodymyr Zelensky said on Sept. 25 during his speech at the U.N. General Assembly in New York.

Russia launched nine coordinated attacks against Ukraine’s electricity infrastructure between March and August, striking facilities in 20 oblasts.

According to an International Energy Agency (IEA) report, Ukraine’s electricity shortage could reach 6 gigawatts this winter as a result of the attacks, which is about one-third of the expected peak demand. This summer, the power shortage was 2.5 GW when Kyiv was already experiencing long blackouts.

“This is how Putin is preparing for winter — hoping to torment millions, millions of Ukrainians… Ordinary families — women, children… Ordinary towns, ordinary villages,” Zelensky said.

“Putin wants to leave them in the dark and cold this winter, forcing Ukraine to suffer and surrender. Just imagine, please, your country with 80 percent of its energy system gone — with such a destroyed part of the system. What kind of life would that be?” the president added.

From October 2022 to September 2024, Ukraine’s energy infrastructure facilities suffered 1024 Russian attacks, according to the Energy Ministry.

Zelensky told the U.N. Security Council on Sept. 24 that Russia was preparing to target three Ukrainian nuclear power plants.
