Overnight, Moscow's missile and drone strikes have led to electricity outages in large parts of Ukraine's capital, Kyiv.
Nine people were injured while residents 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 different assault in the Zaporizhzhia region in the country's south-east, according to local officials.
Moscow has intensified strikes on energy facilities over the last fortnight, while Ukrainian leadership has demanded "real steps" from international partners to exert influence on Moscow.
"What's needed is not symbolic gestures but firm measures - from the America, European nations and the major economies - in supplying protection systems and enforcing sanctions," was stated in a online statement.
Officials stated that numerous aerial vehicles and more than 30 rockets attacked the country's power systems, labeling such attacks as "cynical and calculated" and against "essential services" as winter approaches.
Government representatives said Moscow was "conducting extensive attacks" and technical staff were laboring to restore power.
A series of attacks struck electrical systems and apartment buildings in the capital.
Several of the people injured in the strikes on the capital have been hospitalized, according to city authorities.
Local officials said the metropolitan region came under intense attacks throughout the evening. A young boy died and three other people were injured.
The assaults follow evenings of bombing campaigns in the territory, sections of which are currently controlled by Russian forces.
The whole nation is in a state of readiness for hypersonic Kinzhal missile strikes, which are tougher to identify.
Government officials told reporters that Russia was deliberately attempting to demolish the country's energy grid, with assaults already affecting gas facilities.
He said energy workers and government agencies were anticipating additional strikes.
