Overnight, Russian missile and drone strikes have led to blackouts in large parts of the capital city, Kyiv.
Nine people were hurt while residents in the city's east were left without electricity and dealt with disruption to water supplies, per reports from city officials.
Meanwhile, a young boy was fatally injured in a distinct aerial attack in the Zaporizhzhia region in the southern area, based on information from area administrators.
Moscow has intensified strikes on power infrastructure over the last fortnight, while Ukrainian leadership has demanded "real steps" from international partners to exert influence on Moscow.
"What's needed is not superficial actions but strong steps - from the America, European nations and the major economies - in supplying protection systems and applying restrictions," was stated in a public message.
Authorities reported that 450 drones and over thirty missiles attacked the country's power systems, characterizing such attacks as "strategic and deliberate" and against "essential services" as the weather cools.
Government representatives said Moscow was "launching a major assault" and maintenance teams were working to repair systems.
A wave of strikes damaged power facilities and apartment buildings in the capital.
Five out of the nine people injured in the assaults on the city have been hospitalized, as confirmed by local officials.
Local officials said the city experienced heavy assaults throughout the evening. A minor died and three other people were wounded.
The strikes follow periods of aerial attacks in the region, sections of which are currently controlled by Russian forces.
The entire country is on alert for hypersonic Kinzhal missile strikes, which are tougher to detect.
National leaders told the media that Moscow was intentionally trying to damage the country's energy grid, with strikes already affecting energy systems.
Officials stated utility staff and government agencies were preparing for more assaults.
