Moscow has escalated strikes on power infrastructure over the past few days, while the country's government has demanded "real steps" from international partners to increase pressure on Russia.
"What's needed is not superficial actions but firm measures - from the US, the EU and the major economies - in delivering protection systems and implementing penalties," mentioned in a online statement.
Authorities reported that numerous aerial vehicles and more than 30 missiles targeted Ukraine's energy infrastructure, describing such assaults as "cynical and calculated" and against "everything that sustains normal life" as winter approaches.
Government representatives said Russia was "launching a major assault" and repair crews were working to fix the damage.
A series of attacks struck power facilities and residential structures in Kyiv.
Five out of the nine people injured in the attacks on the capital have been transported for medical care, as confirmed by local officials.

The strikes succeed evenings of air raids in the territory, parts of which remain under the control of Moscow's military.
All of Ukraine is in a state of readiness for hypersonic Kinzhal missile strikes, which are tougher to detect.
