During the night, Russian missile and drone strikes have resulted in electricity outages in large parts of Ukraine's capital, Kyiv.
A number of civilians were hurt while residents in eastern districts were experienced blackouts and encountered disruption to drinking water, according to local authorities.
Meanwhile, a minor was fatally injured in a separate assault in the Zaporizhzhia region in the southern area, according to local officials.
Moscow has intensified assaults on power infrastructure over the past few days, while Ukrainian leadership has called for "real steps" from international partners to exert influence on Moscow.
"What's needed is not superficial actions but decisive action - from the America, European nations and the G7 - in supplying protection systems and implementing penalties," was stated in a online statement.
Officials stated that hundreds of unmanned aircraft and more than 30 missiles attacked the country's power systems, characterizing such attacks as "premeditated" and against "essential services" as the weather cools.
Government representatives said Russia was "conducting extensive attacks" and maintenance teams were striving to fix the damage.
A wave of strikes hit power facilities and civilian homes in Kyiv.
Multiple people wounded in the attacks on the city have been transported for medical care, as confirmed by municipal representatives.
Area administrators said the city came under significant strikes during nighttime hours. A minor died and three other people were wounded.
The strikes succeed evenings of aerial attacks in the area, portions of which are occupied by Moscow's military.
All of Ukraine is under warning for hypersonic Kinzhal missile strikes, which are harder to spot.
Authorities told journalists that Russia was purposely seeking to demolish the national power system, with strikes already affecting energy systems.
He said energy workers and government agencies were preparing for additional strikes.
