Electricity and steam for the CHEMPARK in Dormagen

Under the terms of the steam- and electricity-supply contract for what is now CHEMPARK (Bayer at the time of signing) of March 1998, RWE Generation SE committed to constructing a modern combined-cycle gas turbine (CCGT) plant on the premises.

After only 20 months of construction, the supply of steam to the Dormagen plant from the new combined-cycle power plant was safely resumed on July 1, 2000. The natural gas-fired combined cycle power plant (boiler 10), which was taken over from the former Bayer AG, is decommissioned in the meantime. Steam supply is currently secured by a steam boiler system built by the CHEMPARK operator CURRENTA. As a result of the security, electricity can also be purchased flexibly on the external market if required - in the spirit of the energy transition and depending on the availability of cheap electricity from renewable energies.

Max. output: 560 megawatts

Each of the two gas turbines has an output of 190 MW, while the downstream steam turbine also has a maximum output of 190 MW. Taking into account the plant-related minimum steam extraction (100 t/h) and after deducting the CCGT's own requirements, its maximum electric output amounts to 560 MW. RWE generates electricity for CHEMPARK operators CURRENTA with up to 260 MWel. All electricity that is generated is fed into the local 110-kV grid.

Steam extraction in line with operational requirements

Next to electrical generation, process-steam of up to 500 t/h on the 31, 16 and 6-bar pressure levels is produced. Steam is fed into the grids of CURRENTA, the operator of the chemical park in Dormagen, as required during operations.
