Authorities reported that 450 drones and several dozen rockets targeted the country's power systems, characterizing such assaults as "strategic and deliberate" and against "critical infrastructure" as the weather cools.
Government representatives said Moscow was "conducting extensive attacks" and maintenance teams were laboring to fix the damage.
A barrage of missiles hit electrical systems and civilian homes in Kyiv.
Several of the people injured in the assaults on the city have been hospitalized, according to local officials.
Area administrators said the metropolitan region came under heavy assaults overnight. A seven-year-old child lost their life and three other people were hurt.
The strikes come after evenings of aerial attacks in the territory, sections of which remain under the control of Moscow's military.
