During the night, Russian aerial assaults have resulted in power cuts in extensive areas of the capital city, Kyiv.
Nine people were injured while local people in the city's east were experienced blackouts and dealt with disruption to water supplies, according to local authorities.
Simultaneously, a young boy was killed in a distinct assault in the Zaporizhzhia area in the country's south-east, according to regional authorities.
Moscow has intensified strikes on power infrastructure over the past few days, while Ukrainian leadership has called for "concrete actions" from partner nations to exert influence on Russia.
"What's needed is not window dressing but firm measures - from the United States, the EU and the G7 - in providing protection systems and implementing sanctions," he wrote in a public message.
He said that numerous aerial vehicles and more than 30 rockets struck Ukraine's energy infrastructure, describing such attacks as "strategic and deliberate" and against "essential services" as winter approaches.
Energy officials said Russia was "conducting extensive attacks" and maintenance teams were working to fix the damage.
A series of attacks hit energy infrastructure and residential structures in the capital.
Several of the people injured in the assaults on the capital have been taken to hospital, according to local officials.
Regional authorities said the metropolitan region came under significant strikes during nighttime hours. A young boy lost their life and several individuals were injured.
The assaults succeed periods of air raids in the area, portions of which are currently controlled by Moscow's military.
All of Ukraine is in a state of readiness for advanced weapon attacks, which are harder to detect.
Authorities told the media that Russia was deliberately attempting to damage the national power system, with assaults already disrupting gas facilities.
Authorities confirmed energy workers and officials were bracing for more assaults.
