The new build project
A highly efficient bridging technology supported by the German government in the context of the energy transition.
- It is planned to construct and operate a highly efficient combined cycle gas and steam turbine plant (CCGT plant) at the Herne power plant site.
- The construction of the modern plant will be subsidized by the Federal government on the basis of the Act on Combined Heat and Power Generation.
- This energy conversion technology conserves resources as electricity and heat are generated together.
- The Herne combined cycle plant ensures security of supply for heat and power with major savings in CO2 compared with conventional heating power plants.
- The start of construction work is planned for spring 2019, and commissioning for the end of 2021.
First feed-in of the CCGT plant into the power grid
Commissioning is approaching: The gas turbine of the new power plant was successfully fired at the end of December 2021. This was followed by grid synchronization and the first power feeds. By mid-January 2022, 260 megawatts had been reached, around 40 percent of the maximum output.
Herne 4 makes way for CCGT Herne
In March 2021, another milestone is set for the future of energy: STEAG applies for the decommissioning of the Herne 4 coal-fired unit. In the course of 2022, it is to be replaced by the new state-of-the-art and resource-saving combined-cycle power plant. Herne 4 is to be converted into a natural gas-fired boiler to secure the district heating supply.
Ready Steady Go: First work on the fundament of the new CCGT power plant in progress
At the beginning of February 2020, 777 concrete piles, each 15 meters deep, are waiting to be driven into the ground. In the future, they will support the foundation plates for the turbine and generator. After the responsible Arnsberg district government has approved the first construction phase, the team will start work.
