Oleksandr Fomenko, the chief executive of DTEK, said on Friday that only 30% of Kiev had power.
"Emergency shutdowns continue to be in effect in Kiev. From now on, DTEK will turn off the electricity to all residents in turns, so that the interruption in power supply for each client is no more than five hours," the Ukrainian utility said in a Saturday statement on social media.
Earlier in the day, the Kiev military administration said on social media that some 130,000 people in the Ukrainian capital were still without power as of Saturday morning following a massive blackout this week.
Later in the day, Kiev Mayor Vitali Klitschko said that a quarter of residents of Ukraine's capital had no power as of Saturday, but the city was already able to switch to scheduled power outages.
According to Ukraine's chief negotiator at the now-stalled talks with Russia Davyd Arakhamia, about 20% of heating points in Kiev are closed. Arakhamia said, as cited by Ukrainian news portal Strana.ua on Saturday, that there are no heat generators at some of the locations, while others have been closed due to a lack of water or internet. He said that the issues are expected to be resolved "within two to three days."
Much of Kiev was plunged into darkness on Wednesday after Russia struck the city’s military command posts and the related power grid. The Ukrainian Energy Ministry said a day later that it had restored power supply to critical infrastructure.
Ukrainian President Volodymyr Zelensky said on November 1 that about 40% of Ukraine's energy infrastructure had been damaged as a result of Russia’s precision strikes against Ukrainian infrastructure that began on October 10, in retaliation for the terrorist attack on the Crimean bridge, leading to mass blackouts throughout the country. Ukraine has introduced rolling blackouts to repair the energy grid ahead of winter.
Ukrainian media reported last week citing DTEK, the largest private investor in Ukraine's energy sector, that blackouts could get longer in Ukraine as winter approaches and temperatures drop.
