The company announced this on Facebook.
"Today, on May 14, from 21:00 to 24:00, Ukrenergo is forced to introduce controlled emergency shutdowns in all regions of Ukraine," the post reads.
The reason for this is a significant shortage of electricity in the country's power grid due to Russian strikes and increased consumption due to a cold snap.
On May 15, power outages will be introduced for industrial consumers throughout the day - from 00:00 to 24:00.
Large-scale Russian attacks on energy facilities resumed on March 22. The strikes damaged the Burshtynska, Ladyzhynska, Zmiivska and Trypilska thermal power plants, as well as hydroelectric power plants.
