The power station consisted of five units that power the Evonik Marl chemical plant, owned by Evonik Industries. Three of the units were coal-fired, commissioned from 1968 to 1983.[1] They primarily provide combined heat and power to Chemiepark Marl, which produces various chemicals.[2]

A proposed 900 MW coal expansion was put on hold in 2011, and appears to be cancelled.[3] In 2017, one coal unit was retired, leaving two coal-fired units totaling 136 MW.[4]

The two proposed 90 MW gas units are meant to replace the remaining coal units.[5] Units CC6 and CC7, both of which are combined-cycle gas-and-hydrogen fired turbines are currently under construction, and are expected to be commissioned in 2022.[6]
