80% of generation lost: DTEK CEO highlights energy sector’s severe challenges amid war

“We witnessed the biggest attack on our infrastructure,” he said.

“We lost 80% of generation after the first two attacks. These are definitely the most difficult times since the beginning of the full-scale invasion in terms of the country’s energy supply and the destruction scale.”

The lack of air defense systems is the main problem as of now, he thinks.

“We can restore power plants, deliver additional equipment, but we don’t know what will happen the following day,” Tymchenko said.

Russia’s massive attack on Ukraine on April 11

Russia launched another mass attack on Ukraine using Shahed kamikaze drones, cruise missiles launched from Tu-95MS aircraft, and Kinzhal hypersonic missiles and guided air missiles from Su-34 jets overnight on April 11.

At least 10 strikes targeted Kharkiv and its surrounding areas, leading to new power outages in the city.

Lviv Oblast, particularly the city of Stryi, also faced heavy combined attacks.

Russia reportedly targeted critical infrastructure in Zaporizhzhya in Kyiv oblasts, local authorities reported.

The energy systems of four regions — Kyiv, Lviv, Zaporizhzhya, and Kharkiv — came under attack, with two DTEK thermal power plants suffering serious damage, Energy Minister Herman Halushchenko said.

Ukrainian air defense forces shot down 37 out of 40 Shahed kamikaze drones during the night and morning of April 11, the General Staff said.
