Großkrotzenburg Power Station is a modern coal-fired thermal power station in Großkrotzenburg, Hesse, east of Frankfurt, Germany. It comprises five units with a total capacity of approximately 1100 MW. The units were built between 1965 and 1992. Units 1-3 were decomissioned in 2012 and 2013. A characteristic of this power station is the fact that the most recently built unit, Unit 5, does not have a waste gas flue. Instead, the desulphurised flue gases are expelled using the updraught from the existing cooling towers. The power station is operated by Uniper.
