russian attacks in October damaged five of the six thermal power plants run by DTEK. The company had successfully undergone repairs. But after a pause of a few weeks, russian again unleashed strikes on Tuesday last week.

During this latest wave, at least one of DTEK`s plants was hit, and the rest were running at about 50 percent capacity, DTEK CEO Maxim Timchenko told Vox.

Some of Ukraine’s infrastructure, like its coal-fired plants, were built during the Soviet era, adding to the difficulty of repairs.  DTEK has to sometimes reallocate parts from other Ukrainian plants, or find similar models from other former Soviet states, like in Eastern Europe, that might have similar specifications. “The biggest concern is that we run out of stock, and it cannot be replaced,” Timchenko said.
