The cogeneration plant Duisburg-Wanheim has an electrical output of 279 MW and a thermal output of 255 MW. It belongs to the Stadtwerke Duisburg and is operated with natural gas ; as a backup, operation with heating oil is also possible. The power plant is connected to the 110 kV network of Netze Duisburg via its own substation. The plant consists of two blocks, HKW III / A and III / B. Unit A was built in 2002 and has a net output of 40 MW. The gas and steam turbine power plant unit B went into operation in 2005 and has a gross electrical output of 245 MW, with a maximum heat output of 167 MW.

The cooling tower of the power plant is illuminated in green at night and thus represents a characteristic landmark that can be seen from afar from the opposite bank of the Rhine.

District heating supply

After the shutdown of the two coal blocks HKW II at the end of 2012 and HKW I at the Hochfeld location in March 2018, the power plant in Wanheim is the last cogeneration plant of Stadtwerke Duisburg, which supplies the district heating network with hot water up to 130 ° C. 70,000 heating customers are supplied, the amount of heat released is 700 GWh with a maximum load of 310 MW (as of 2019).

To improve the management one was for 20 million euros district heating storage at the site Wanheim built so that in summer the heat customers can be up to 70 operated from the store hours, without the co-generation plant must be running. The reservoir has a height of 44 m and a diameter of 36 m. The capacity is approx. 43,000 m³ of water and can absorb 1450 MWh of heat. Thanks to the modern, pressureless two-zone design, storage temperatures of up to 115 ° C can be achieved.

Furthermore, a district heating pipe to the Niederrhein district heating system in the north of the city was built in 2018 to improve security of supply (length 6 km, inner diameter 0.4 m including insulation 0.63 m, project volume approx. 8 M €), via which industrial waste heat is also obtained can be.
