Kyiv authorities say that repair work on the power grid is now in its "final phase." Millions had been left without power following Russian strikes targeting critical infrastructure on Wednesday.
Military administration in Ukrainian capital reported Sunday that power had been "almost completely" restored in the city as of 9 a.m. local time (0700 GMT), according to a post on the Telegram message.
Repair work on the power grid is now in its "finale phase," authorities said.
Water, heat and mobile networks have also been restored in the capital, according to the Telegram post.
Kyiv authorities said that "planned outages" and "local power failures" were still possible.
Russia has increasingly been targeting Ukraine's energy infrastructure over the past weeks, with a series of strikes on Wednesday leaving millions of people without light, water or heat.
President Volodymyr Zelenskyy said that 6 million households across the country had been affected by power cuts following Wednesday's strikes, with around 600,000 affected in Kyiv.
On Friday, Zelenskyy criticized Kyiv mayor Vitaliy Klitschko for doing what he said was a poor job at setting up emergency heat shelters.
