Emergency power outages were introduced in parts of Kyiv, Kharkiv, Poltava, Vinnytsia, and Sumy around noon on May 30 due to a decrease in the system's frequency, reported Ukraine's Energy Ministry.
The reason for the shutdowns is still unclear, as electricity generation fully covers current consumption. The Russian overnight attack on Kyiv Oblast didn't cause any damage to the energy infrastructure, according to the ministry.
Ukraine's state energy operator Ukrenergo pledged to restore the power supply to all consumers "in the next few hours."
According to Ukrenegro, several major high-voltage lines in the power system were accidentally disconnected, which made the emergency mechanism cut off power in parts of Ukraine. The incident is being investigated.
Earlier, the Energy Ministry reported that Russian attacks against Donetsk, Dnipropetrovsk, Sumy, and Kharkiv oblasts caused blackouts in some frontline settlements.
Part of the consumers in Zaporizhzhia, Kherson, and Chernihiv oblasts are still without electricity due to earlier Russian strikes, the ministry added.
Russian troops launched another drone attack against Kyiv Oblast overnight on May 30, targeting Ukraine for the 17th time this month. The attack killed one person and injured nine in the capital as well as wounded four more elsewhere in Kyiv Oblast.
The Kyiv police reported 16 property damage cases, including residential buildings and cars.
