His successor is Nikolaus Valerius (pictured), who will take up the position on 1 April.
Valerius has the task of “driving forward” the new technologies at RWE Generation in particular, hydrogen-ready gas-fired power plants, the production of green hydrogen and battery storage.
Markus Krebber, CEO of RWE, said: “I am very pleased that he is taking over the management of RWE Generation as another proven expert with excellent knowledge of the energy industry.”
Valerius has held a number of positions at RWE since 1995.
From 2017 to 2023, he was a member of the Executive Board of RWE Power, where he was responsible for the Nuclear Energy division.

Krebber thanked Miesen for his work.
“Over the years, Roger has put his all into managing our gas, hard coal/biomass and hydropower plants at RWE, was responsible for the Nuclear Energy division and took over as CEO of RWE Generation in 2018.
“In recent years, he has consistently prepared RWE Generation’s flexible international power plant portfolio to gradually become climate-neutral.
