The Supervisory Board of Uniper SE has formally appointed Michael Lewis as Chief Executive Officer (CEO) of Uniper SE effective 1 June 2023. His contract is valid for a period of five years. The originally planned start date was 1 July. Also, on 1 August 2023, Carsten Poppinga will start as new Chief Commercial Officer (CCO) of Uniper, taking over seamlessly from Niek den Hollander, who will step down from his post on 31 July as announced.

Tom Blades, Chairman of the Uniper Supervisory Board: “Michael Lewis’ and Carsten Poppinga’s earlier start dates are good news for us. The Uniper colleagues are looking forward to their new CEO and CCO. With the start of Michael Lewis, Jutta Dönges and Holger Kreetz will be able to focus fully on their own departments and projects from June onwards again. Both are representing the CEO excellently, for which I would like to express my sincere thanks already. I would also like to thank the previous employers E.ON and Statkraft for the constructive discussions in recent weeks.”

Michael Lewis, designated Uniper CEO: “It is important for me to start at Uniper before the summer break. This gives me the time to get to know the company and the people before we hit the ground running in the second half of the year. We have a lot to do and I’m looking forward to getting started.”

Carsten Poppinga, designated Uniper CCO: “The global trading business is of great importance to the energy industry and an essential part of Uniper. I am all the more excited to take on the role of CCO at the publication of the half-year figures on 1 August. Together with the team, we will continue to drive the energy transition and the diversification of Uniper’s portfolio.”
