Moscow has increased strikes on electrical systems over the last fortnight, while officials has demanded "concrete actions" from allies to increase pressure on Russia.
"What's needed is not window dressing but strong steps - from the United States, the EU and the Group of Seven - in providing defensive weapons and applying restrictions," was stated in a public message.
Authorities reported that 450 drones and more than 30 missiles struck the country's power systems, describing such attacks as "premeditated" and against "essential services" as temperatures become colder.
Government representatives said Russia was "conducting extensive attacks" and technical staff were striving to restore power.
A barrage of missiles struck energy infrastructure and apartment buildings in the capital.
Several of the people hurt in the attacks on the city have been taken to hospital, per statements from local officials.
Local officials said the city came under intense attacks throughout the evening. A young boy lost their life and multiple civilians were wounded.
The assaults follow periods of air raids in the region, sections of which are occupied by Russian forces.
The entire country is under warning for advanced weapon attacks, which are harder to detect.
Authorities told the media that Moscow was deliberately attempting to damage the national power system, with attacks already impacting energy systems.
