Overnight, Moscow's aerial assaults have resulted in power cuts in extensive areas of the capital city, Kyiv.
Nine people were injured while inhabitants in eastern districts were experienced blackouts and faced problems to water supplies, according to municipal leaders.
At the same time, a young boy was fatally injured in a separate assault in the Zaporizhzhia area in the southeastern part, according to regional authorities.
Moscow has intensified strikes on energy facilities over the last fortnight, while Ukrainian leadership has demanded "concrete actions" from international partners to increase pressure on Russia.
"What is required is not symbolic gestures but strong steps - from the US, Europe and the major economies - in delivering defensive weapons and implementing penalties," was stated in a public message.
He said that 450 drones and several dozen rockets attacked energy facilities, labeling such attacks as "premeditated" and against "everything that sustains normal life" as the weather cools.
Energy officials said Moscow was "launching a major assault" and technical staff were striving to restore power.
A series of attacks struck power facilities and residential structures in Kyiv.
Five out of the nine people injured in the attacks on the capital have been transported for medical care, according to municipal representatives.
Area administrators said the urban area came under intense attacks throughout the evening. A minor lost their life and three other people were injured.
The strikes succeed periods of bombing campaigns in the area, parts of which are currently controlled by invading troops.
The entire country is under warning for advanced weapon attacks, which are harder to spot.
Government officials told reporters that Russia was purposely seeking to damage the national power system, with assaults already disrupting fuel infrastructure.
Authorities confirmed utility staff and government agencies were bracing for further attacks.
