During the night, Moscow's aerial assaults have led to blackouts in large parts of the capital city, Kyiv.
Several individuals were injured while local people in the city's east were left without electricity and encountered interruptions to water supplies, according to city officials.
Meanwhile, a young boy was lost their life in a distinct aerial attack in the Zaporizhzhia region in the country's south-east, based on information from regional authorities.
Moscow has intensified attacks on electrical systems over the past few days, while the country's government has called for "substantial measures" from international partners to increase pressure on Moscow.
"The necessity is not symbolic gestures but decisive action - from the America, the EU and the major economies - in delivering protection systems and implementing penalties," he wrote in a public message.
He said that hundreds of unmanned aircraft and more than 30 rockets struck Ukraine's energy infrastructure, characterizing such attacks as "cynical and calculated" and against "essential services" as temperatures become colder.
Energy officials said Russia was "launching a major assault" and maintenance teams were laboring to repair systems.
A wave of strikes struck power facilities and residential structures in the capital.
Five out of the nine people injured in the assaults on the city have been transported for medical care, per statements from city authorities.
Area administrators said the urban area experienced significant strikes overnight. A minor died and several individuals were hurt.
The attacks follow periods of bombing campaigns in the area, parts of which remain under the control of invading troops.
All of Ukraine is under warning for hypersonic Kinzhal missile strikes, which are more difficult to detect.
Authorities told the media that Moscow was intentionally trying to demolish the national power system, with attacks already impacting fuel infrastructure.
Authorities confirmed energy workers and officials were anticipating further attacks.
