Overnight, Russian aerial assaults have resulted in blackouts in large parts of Ukraine's capital, Kyiv.
Nine people were injured while local people in eastern districts were experienced blackouts and encountered problems to drinking water, according to local authorities.
Simultaneously, a young boy was lost their life in a distinct assault in the Zaporizhzhia area in the country's south-east, based on information from local officials.
Moscow has increased strikes on power infrastructure over recent weeks, while officials has requested "real steps" from allies to increase pressure on Russia.
"The necessity is not superficial actions but strong steps - from the America, the EU and the major economies - in providing air defence systems and enforcing penalties," he wrote in a public message.
Authorities reported that 450 drones and several dozen missiles targeted Ukraine's energy infrastructure, describing such strikes as "cynical and calculated" and against "critical infrastructure" as temperatures become colder.
Energy officials said Russia was "conducting extensive attacks" and maintenance teams were striving to fix the damage.
A series of attacks hit electrical systems and apartment buildings in Kyiv.
Multiple people wounded in the attacks on the capital have been hospitalized, according to city authorities.
Regional authorities said the city endured heavy assaults overnight. A minor was killed and multiple civilians were hurt.
The attacks come after nights of air raids in the region, portions of which remain under the control of invading troops.
The entire country is in a state of readiness for advanced weapon attacks, which are tougher to identify.
Government officials told reporters that Moscow was intentionally trying to damage the electrical infrastructure, with strikes already disrupting gas facilities.
Officials stated technical personnel and government agencies were bracing for more assaults.
