"The necessity is not window dressing but firm measures - from the America, European nations and the Group of Seven - in delivering defensive weapons and enforcing sanctions," was stated in a online statement.
Officials stated that hundreds of unmanned aircraft and more than 30 projectiles attacked energy facilities, describing such attacks as "cynical and calculated" and against "everything that sustains normal life" as temperatures become colder.
Energy officials said Russia was "launching a major assault" and technical staff were working to restore power.
A wave of strikes damaged power facilities and civilian homes in Kyiv.
Multiple people wounded in the attacks on the city have been hospitalized, according to local officials.
