During the night, Moscow's missile and drone strikes have caused power cuts in large parts of the capital city, Kyiv.
Nine people were hurt while residents in the city's east were plunged into darkness and faced disruption to water systems, according to municipal leaders.
Meanwhile, a young boy was killed in a distinct aerial attack in the southeastern region in the southeastern part, according to local officials.
Moscow has increased strikes on electrical systems over recent weeks, while the country's government has requested "substantial measures" from allies to apply pressure on Moscow.
"The necessity is not superficial actions but strong steps - from the United States, the EU and the Group of Seven - in providing defensive weapons and applying penalties," he wrote in a online statement.
Officials stated that numerous aerial vehicles and several dozen projectiles targeted energy facilities, characterizing such strikes as "cynical and calculated" and against "essential services" as the weather cools.
Energy officials said Russia was "launching a major assault" and repair crews were striving to fix the damage.
A series of attacks damaged energy infrastructure and civilian homes in Kyiv.
Several of the people wounded in the assaults on the capital have been taken to hospital, as confirmed by city authorities.
Local officials said the urban area endured intense attacks overnight. A seven-year-old child was killed and three other people were hurt.
The assaults follow periods of air raids in the region, portions of which remain under the control of Russian forces.
The entire country is on alert for hypersonic Kinzhal missile strikes, which are harder to detect.
Government officials told the media that Russia was intentionally trying to demolish the electrical infrastructure, with attacks already affecting energy systems.
He said utility staff and government agencies were anticipating more assaults.
