"We are more than confident, especially after last week's attack, that russia has no chance of plunging Ukraine into darkness,"

he said during a speech at the Kyiv Security Forum. 

Timchenko noted that no energy system in the world, which is the same size as the Ukrainian one, has ever suffered such a scale of damage as our energy system received last week.

He added that after the shelling in some regions, power workers managed to restore electricity supply in a few hours, and in some - in a few days.

"We know how to deal with these difficult situations. We use our technical creativity to connect different parts of the energy system,"

concluded DTEK CEO.

On November 23, russia delivered another massive attack on energy infrastructure of Ukraine. As a result of shelling, emergency power outages have rolled across the country.

Also, on December 1, the russians once again shelled one of the DTEK’s power plants. Over the past two months, the company's energy facilities have been fired upon 16 times.
