RWE has completed the installation of all foundations for its 1.1-gigawatt Thor offshore wind farm in the Danish North Sea, marking a major construction milestone. The final monopile of the 72 required was installed in September, and last week, RWE concluded the placement of all secondary steel structures—including boat landings, main access platforms, and internal components—using Van Oord’s MPI Adventure installation vessel. The foundation work was completed in under six months, with operations managed from the Port of Thyborøn.
To safeguard the foundations until turbine installation begins, RWE has fitted reusable hard covers designed to withstand harsh marine conditions. Earlier this year, the 2,600-tonne offshore substation topside was successfully installed on its jacket foundation. Turbine installation is scheduled to begin from the Port of Esbjerg in spring 2026, with Thor set to become the world’s first offshore wind farm using 36 low-carbon steel towers and recyclable rotor blades. Once operational in 2027, Thor will generate enough renewable electricity to power more than one million Danish homes.
RWE’s operations and maintenance plan will create 50 to 60 permanent local jobs at a new service facility in the Port of Thorsminde, currently under construction and expected to be completed by early 2026. The Thor project is jointly owned by RWE (51%) and Norges Bank Investment Management (49%), with RWE leading construction and operations throughout the project’s lifecycle.
Sven Utermöhlen, Chief Executive Officer RWE Offshore Wind, said, “Our Thor project is progressing very well, with offshore works on schedule. We look forward to starting turbine installation next year, which will mark the next major milestone in delivering Denmark’s largest offshore wind farm to date. I would like to thank our partner, Norges Bank Investment Management, as well as our suppliers and colleagues for their dedication to collaboration, quality, and safety.”
