KYIV, Nov 22 – With massive air strikes, the most powerful of which took place on November 15, Russian invaders damaged almost all thermal and large hydroelectric power plants in Ukraine, Volodymyr Kudrytsky, board chairman of NPC Ukrenergo, said.

"After the last attack, we practically had no undamaged thermal and hydroelectric power plants left. That is, in order for you to understand the scale and what we have to work with, almost all thermal and hydropower generation, if we are talking about large objects, was subjected to missile strikes," Kudrytsky said during a briefing at a media center in Kyiv on Tuesday.
