On Sunday, emergency assistance was activated at the request of the Polish power system. Ukraine accepted surplus electricity that the Polish power system had during daytime hours in the amount of 1,800 MWh, Ukrenergo reports.

"This is not a commercial import, but one of the types of emergency aid," the company emphasized.

Poland had a surplus of electricity during the daytime hours of the weekend and asked neighboring countries for help in its consumption. In this way, Ukraine received an additional amount of electricity.

"Ukraine only has such contract terms with Poland," Ukrenergo added.

However, the commercial exchange of electricity continues. The planned import from Slovakia with a capacity of 90-170 MW is carried out mainly during daytime hours. There is no export and import in the evening hours of peak consumption.

Overall, electricity production currently meets Ukrainian demand. However, hydropower output is decreasing due to lower water levels while thermal and nuclear power plants undergo summer maintenance outages, limiting available capacity.

In Kherson Oblast, water is receding slowly amid constant shelling. Over 40,000 consumers lack power in the city and region. Where possible, regional electricity distribution company repair crews are working to restore service; over 2,000 consumers have been reconnected.

In Mykolaiv Oblast, receding water enabled over 2,000 flooded consumers to regain power.

Border and frontline regions face damage from Russian shelling, including to energy networks in Sumy, Kharkiv, Zaporizhzhya, and Donetsk oblasts. The regional electricity distribution company repair crews restore power after permission from the military.

In Kyiv, Chernihiv, Zhytomyr, Sumy, Dnipropetrovsk and Kirovohrad oblasts, regional networks were damaged due to adverse weather conditions.

On Thursday, emergency aid from Romania and Poland was used to balance Ukraine's energy system.
