Authorities reported that numerous aerial vehicles and several dozen projectiles struck the country's power systems, labeling such strikes as "premeditated" and against "everything that sustains normal life" as temperatures become colder.
Energy officials said Russia was "launching a major assault" and repair crews were working to fix the damage.
A wave of strikes struck electrical systems and residential structures in the capital.
Multiple people wounded in the strikes on the capital have been hospitalized, according to municipal representatives.
Regional authorities said the urban area came under significant strikes overnight. A seven-year-old child was killed and multiple civilians were wounded.
The attacks follow nights of aerial attacks in the territory, portions of which are currently controlled by Moscow's military.

Government officials told reporters that Moscow was purposely seeking to destroy the electrical infrastructure, with assaults already disrupting energy systems.
He said technical personnel and authorities were preparing for further attacks.
