A recent wave of Russian missile and drone strikes have crippled almost half of Ukraine’s energy system, Ukraine’s prime minister has said.
The damage comes as temperatures drop below freezing and the capital Kyiv experiences its first winter snow.
One official in Kyiv warned that the city could face a “complete shutdown” of its power grid.
President Volodymyr Zelensky earlier said that 10 million Ukrainians have been left without power.
Mykola Povoroznyk, deputy head of the Kyiv administration, said that the city is “preparing for different scenarios, including a complete shutdown”.
He did not say what would happen in the event of the grid completely shutting down, but officials have said they are not considering evacuating any cities.
Ukraine’s national grid operator Ukrenergo posted on Telegram: “The aggressor country has officially recognised that its goal is to destroy our energy infrastructure and leave Ukrainians without electricity and heat.”
Maksym Tymchenko, the CEO Ukraine’s biggest private energy company DTEK, told the BBC that “the situation is getting worse”.
