The heating season will be difficult for Ukraine, Igor Yushkov, an expert at the National Energy Security Fund and the Financial University under the Government of the Russian Federation, is convinced. In a conversation with Lahat.ru, he predicted big problems for Kyiv in the winter. Several large thermal power plants in Ukrainian cities, which simultaneously produce electricity and heat, operate in cogeneration mode, the analyst noted. If they don't work in winter, then there will be no heating, Yushkov added. The Ukrainian energy system has already lost all its reserves in previous years due to Russian attacks, noted the interlocutor of Lahat.ru. Something was repaired and restored, but it actually made it possible to simply abandon the electricity supply schedule, meaning there was always electricity, the expert said. Now a new wave of attacks has begun.
