The Dradenau Combined Heat and Power Plant project of the ARGE Uniper-ENKA Dradenau partnership in Germany is progressing steadily. This strategically important project for Hamburg aims to replace the coal-fired CHP plant in Wedel with a new and environmentally friendly CHP plant in Dradenau (KWK-Anlage Dradenau).
The project is based on a 2x2x1 configuration consisting of two Siemens SGT-800 gas turbines, one steam turbine, two heat recovery steam generators (HRSG), and one additional gas-fired steam generator. Upon completion, the plant will deliver an electrical output of 180 MW and a district heating capacity of 260 MW.
As of the end of 2025, overall project progress has reached 87%, with approximately 950 personnel, including subcontractors, actively working on site. A total of 638,838 person-hours and 107 days of work have been recorded without any Lost Time Incident (LTI).
Façade and roof installations for the Electrical, Gas Compressor, and Administrative Control buildings have been completed. The structural steel installation of the Power Block building, totaling approximately 4,300 tons, has been successfully completed, and façade works following the steel erection have been largely finalized. Architectural works and infrastructure activities are ongoing, progressing according to the planned schedule with close coordination among disciplines.
Mechanical works include a total of 102,000 dia-inch piping welds completed across the project. Hydrotesting and insulation works are being carried out in parallel. Installation of main and auxiliary mechanical equipment has been completed, and hydrotesting of the HRSG piping has been successfully conducted. Commissioning activities have begun for the gas turbines and the water treatment plant.
Electrical works include completed installation of transformers, panels, and auxiliary equipment, along with approximately 500,000 meters of cable pulling. AC/DC uninterruptible power systems, batteries, and auxiliary transformers have also been handed over to the commissioning teams.
The plant is scheduled for its first fire in May 2026, with commissioning and performance testing to be completed, aiming for overall project completion by the final quarter of 2026.
