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 2 Siemens SGT-800 gas turbines, 1 steam turbine, 2 heat recovery steam generators (HRSG), and 1 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 mid-June 2026, overall project progress has reached 92.3%, with approximately 900 personnel, including subcontractors, actively working on site. A total of 1.67 million person-hours and 273 days of work have been recorded without any Lost Time Incident (LTI).
Façade and roof installations for the Electrical, Gas Compressor, and Admin Control buildings have been completed. The 4,300-ton structural steel installation of the Power Block building has also been successfully completed. Following steel erection, 10,360 m² of façade works and 10,275 m² of roof cladding have been completed. Architectural and infrastructure activities are continuing in line with the project schedule.
Mechanical works have progressed significantly, with a total of 146,800 dia-inch piping welds completed across the project. Hydrotesting activities have been largely completed, while insulation works continue in parallel. Installation of main and auxiliary mechanical equipment has been completed, and the HRSGs are being prepared for handover to the commissioning team. Chemical cleaning of the main lines and the Fuel Gas System connection to the regulating and metering station (RMS) have also been completed.
Electrical works, including the installation of transformers, panels, and auxiliary equipment, approximately 810,000 meters of cable pulling, and Black Start batteries, have been completed. Instrument installation and termination activities are ongoing in line with system commissioning priorities.
Commissioning activities are progressing according to schedule. The Water Treatment Plant has been successfully commissioned and is producing demineralized water, while major portion of the gas turbine testing activities has been completed. Several transformers and AC/DC uninterruptible power systems have been successfully commissioned.
Commissioning activities of gas pipelines for the Gas Compressor, GSG, HRSGs and Gas Turbines have also been completed. In addition, all tests for the main transformers and high-voltage systems have been completed, and the plant has been successfully energized from the grid, achieving the significant milestone of Backfeed Energization.
