During the night, Russian aerial assaults have caused electricity outages in large parts of the capital city, Kyiv.
Nine people were injured while local people in the city's east were plunged into darkness and encountered interruptions to water supplies, per reports from local authorities.
Meanwhile, a minor was killed in a separate Russian drone strike in the southeastern region in the southeastern part, based on information from area administrators.
Moscow has escalated assaults on power infrastructure over recent weeks, while the country's government has called for "real steps" from allies to apply pressure on Moscow.
"What is required is not superficial actions but decisive action - from the US, European nations and the major economies - in providing air defence systems and enforcing penalties," he wrote in a social media post.
Authorities reported that hundreds of unmanned aircraft and over thirty projectiles struck Ukraine's energy infrastructure, describing such strikes as "premeditated" and against "everything that sustains normal life" as the weather cools.
Government representatives said Moscow was "inflicting a massive strike" and repair crews were working to repair systems.
A wave of strikes hit power facilities and residential structures in Kyiv.
Multiple people wounded in the attacks on the capital have been taken to hospital, per statements from local officials.
Local officials said the city experienced heavy assaults throughout the evening. A young boy was killed and three other people were wounded.
The attacks follow periods of aerial attacks in the area, sections of which are occupied by Russian forces.
All of Ukraine is under warning for sophisticated projectile assaults, which are harder to spot.
Authorities told the media that Moscow was intentionally trying to destroy the national power system, with strikes already impacting fuel infrastructure.
He said utility staff and government agencies were preparing for more assaults.
