Overnight, Moscow's aerial assaults have resulted in blackouts in large parts of Ukraine's capital, Kyiv.
Nine people were injured while residents in eastern districts were left without electricity and faced disruption to water supplies, according to local authorities.
Meanwhile, a seven-year-old child was killed in a separate aerial attack in the southeastern region in the southern area, as reported by area administrators.
Moscow has increased attacks on power infrastructure over recent weeks, while the country's government has requested "real steps" from international partners to apply pressure on Russia.
"The necessity is not superficial actions but strong steps - from the America, Europe and the Group of Seven - in supplying protection systems and implementing penalties," mentioned in a public message.
Authorities reported that 450 drones and over thirty projectiles struck Ukraine's energy infrastructure, characterizing such attacks as "premeditated" and against "essential services" as temperatures become colder.
The energy minister said Russia was "inflicting a massive strike" and maintenance teams were laboring to fix the damage.
A wave of strikes hit power facilities and residential structures in Kyiv.
Multiple people hurt in the assaults on the capital have been transported for medical care, as confirmed by municipal representatives.
Area administrators said the urban area experienced heavy assaults throughout the evening. A young boy was killed and multiple civilians were injured.
The attacks come after nights of aerial attacks in the region, sections of which are occupied by Moscow's military.
All of Ukraine is in a state of readiness for hypersonic Kinzhal missile strikes, which are harder to detect.
National leaders told the media that Russia was intentionally trying to destroy the national power system, with attacks already disrupting fuel infrastructure.
Authorities confirmed technical personnel and officials were preparing for more assaults.
