Ukraine's national power supply company Ukrenergo said 80% of electricity needs nationwide had been restored by 11 a.m. local time (4 a.m. ET) Sunday, after Russian attacks caused widespread blackouts last week.
The company said critical infrastructure consumes only about 10% of the 80% capacity restored. The rest is used to supply electricity to ordinary consumers, like homes and businesses.
Grid operators are still imposing restrictions on how much energy Ukrainians can consume, as a result of the remaining 20% power deficit.
The utility urged residents to continue to use power "sparingly" to allow fewer restrictions, and so energy companies can focus on repairing damaged facilities, "which becomes more difficult with each successive missile attack."
Meanwhile, a local leader in the Kherson region said power grids damaged by Russian shelling Saturday had been restored.
