Throughout the evening, Russian missile and drone strikes have resulted in blackouts in extensive areas of the capital city, Kyiv.
A number of civilians were injured while residents in eastern districts were plunged into darkness and dealt with problems to water supplies, according to municipal leaders.
Simultaneously, a seven-year-old child was killed in a separate assault in the Zaporizhzhia region in the southeastern part, according to local officials.
Moscow has increased attacks on energy facilities over recent weeks, while the country's government has called for "concrete actions" from allies to apply pressure on Russia.
"What is required is not superficial actions but firm measures - from the America, the EU and the Group of Seven - in providing defensive weapons and implementing sanctions," was stated in a social media post.
Authorities reported that hundreds of unmanned aircraft and several dozen rockets struck the country's power systems, characterizing such strikes as "cynical and calculated" and against "essential services" as temperatures become colder.
The energy minister said Russia was "inflicting a massive strike" and technical staff were striving to fix the damage.
A wave of strikes damaged energy infrastructure and civilian homes in the capital.
Five out of the nine people wounded in the assaults on the capital have been transported for medical care, according to city authorities.
Regional authorities said the metropolitan region came under significant strikes throughout the evening. A minor lost their life and three other people were hurt.
The assaults come after nights of aerial attacks in the region, parts of which remain under the control of Moscow's military.
The entire country is in a state of readiness for sophisticated projectile assaults, which are tougher to identify.
Authorities told reporters that Moscow was intentionally trying to demolish the national power system, with assaults already impacting fuel infrastructure.
Authorities confirmed technical personnel and government agencies were anticipating further attacks.
