Who we are
This anniversary is a moment to reflect on our remarkable journey – from our beginnings as a regional company to our current position as a national leader with international reach. Today, DTEK stands as a pillar of strength for Ukraine, bringing light and warmth to millions across both Ukraine and Europe.
As the largest private investor in Ukraine's energy sector, DTEK has invested over €12 billion since 2005 and employs 55,000 people across our operations. Our enterprises span electricity generation from wind, solar, and thermal power plants; energy storage, distribution and supply; natural gas extraction and coal mining; energy trading in Ukrainian and international markets; and comprehensive energy services for both residential and commercial customers.
Our history
DTEK has played a crucial role in Ukraine's energy sector
In 2022, DTEK faced significant challenges due to russia's full-scale invasion of Ukraine. Four out of five of the company’s wind power plants ended up in temporarily occupied territories, resulting in losses of €325 million.
Despite these difficulties, DTEK invested €80 million in coal mining enterprises to ensure the stable operation of thermal power plants and support Ukraine's energy sector.
Our #FightForLight
Since russia launched its full-scale invasion of Ukraine in February 2022, it has set out to destroy our energy infrastructure. As the country’s largest private energy company, DTEK’s campaign to repair the damage, and to restore power to Ukrainian cities and homes, is a fight for freedom, peace and progress. A fight against darkness and destruction. We call it the Fight for Light.
Find out more in our Action Report, which documents the extraordinary speed and scale of DTEK’s restoration efforts, plus our record-pace expansion of wind, solar and battery power – both conducted against overwhelming odds, in extreme and perilous conditions, by our remarkable people.

“On the morning of 24th February, my two daughters were the first to hear the sounds of missiles and aeroplanes. I rushed outside and saw a missile. Four days later, I was at the military commissar’s office; but they needed artillery men and tank crew members, so they told me to go back to work. “The Donetsk region is chaotic nowadays. However, we hold on and do our job. We should all be in our places and continue working.”

“On 24th February, I was on duty. My wife begged me not to go to work since the war had started. We could hear explosions nearby, but work is work, so I started my shift as usual. That same day, I took my family to the bomb shelter on our site. We lived there for about a month. Then I sent my wife and son to relatives in the west, to Kamianets-Podilskyi. “During the early offensive, we were repairing cables on the Irpin highway, sometimes under shelling. It was scary at first, but we got used to it over time. ”

“I still can’t come to terms with all the missile attacks, cities without electricity and water, tortured people. This should not have happened in the 21st century. However, I’ve never had the desire to leave Ukraine. I knew I would work here as long as possible. It is my country and my struggle! “In the summer of 2022, when they announced the recruitment of women to work underground at our mine, I immediately volunteered to become an operator of underground installations. ”

“When there was the first shelling of the Burshtynska TPP in October 2022, I was not ready psychologically. But I managed to gain control of myself. A TPP is a gigantic mechanism, and if any unit fails, all the others collapse as well. So, after the first enemy shelling, I thought: ‘If not me, then who? There are no options.’ It’s about my professionalism. So, I just did what I was trained for. I never left my workplace and managed my colleagues from the control room. “We don’t treat it like a deed of valour.”
