“Ukraine has very big problems with the equipment to maintain the energy system, since all the backup has already been used,” RIA Novosti quotes him as saying.

According to Plachkov, it is not possible to purchase the necessary equipment from other countries.

He added that the most difficult situation was with powerful transformers, which Ukraine does not currently have in stock.

Earlier, the Ministry of Energy of Ukraine reported that on Wednesday, November 23, all nuclear power plants located in the country and most thermal power plants and hydroelectric power plants were temporarily de-energized.

Emergency power outages were introduced in all regions of Ukraine.
