Overnight, Russian aerial assaults have caused power cuts in multiple districts of the capital city, Kyiv.
Nine people were wounded while local people in eastern districts were experienced blackouts and encountered disruption to water systems, according to city officials.
At the same time, a minor was fatally injured in a separate assault in the Zaporizhzhia area in the country's south-east, as reported by area administrators.
Moscow has increased attacks on energy facilities over recent weeks, while the country's government has called for "substantial measures" from international partners to increase pressure on Russia.
"What's needed is not superficial actions but firm measures - from the United States, European nations and the major economies - in delivering air defence systems and applying restrictions," he wrote in a online statement.
Officials stated that 450 drones and several dozen rockets targeted Ukraine's energy infrastructure, characterizing such assaults as "premeditated" and against "critical infrastructure" as temperatures become colder.
Energy officials said Russia was "conducting extensive attacks" and maintenance teams were working to repair systems.
A barrage of missiles struck power facilities and apartment buildings in the capital.
Several of the people injured in the assaults on the city have been taken to hospital, per statements from local officials.
Local officials said the city endured significant strikes throughout the evening. A minor died and several individuals were hurt.
The assaults follow periods of air raids in the territory, parts of which are occupied by Moscow's military.
The entire country is in a state of readiness for hypersonic Kinzhal missile strikes, which are tougher to detect.
National leaders told journalists that Moscow was intentionally trying to destroy the national power system, with strikes already impacting energy systems.
He said utility staff and government agencies were preparing for additional strikes.
