Topping-out ceremony: operations and maintenance base for Thor offshore wind farm nearing completion

  • Denmark’s largest offshore wind farm will be served from a new, state-of-the-art building at Thorsminde port
  • 2,300 square metre building is expected to be completed by the end of 2025
  • Creation of up to 60 permanent jobs expected

Thorsminde, 13 June 2025

Yesterday, RWE and Danish construction company Østermark Entreprenørforretning held a topping-out ceremony for the new building that will be the operations and maintenance base for Denmark's largest offshore wind farm, Thor. At Thorsminde port a wide range of participants from the local area - including neighbours, partners, local craftsmen and representatives from Holstebro Municipality and the local business community - jointly celebrated this milestone.

Pernille Asgaard Haaning, CEO of RWE Renewables Denmark: “The topping-out ceremony not only marks an important milestone for Thor offshore wind farm - it is also a strong symbol of the community and local support that has carried the project forward. The operations building for Thor will be the heart of our daily work and will create lasting local jobs in Thorsminde for many years to come. We are happy to be part of the local community and proud to be able to contribute to making Thorsminde a central hub for Denmark's green future.”

The operations and maintenance base is located at Thorsminde port. With its 2,300 square metres spread over three floors, the state-of-the-art building will house the necessary facilities to ensure the efficient operation of Thor offshore wind farm - including a control room, warehousing and office facilities. As part of the operations and maintenance plan, 50-60 local jobs will be created.

The building is expected to be completed by the end of 2025, and from spring 2026, service vessels will sail technicians and operating personnel to the turbines daily from Thorsminde port. RWE plans to support the wind farm from Thorsminde for at least 30 years.

Work on Thor offshore wind farm is progressing

Construction works continue to progress according to plan. Foundation and cable installation works are underway and installation of the 72 offshore wind turbines is expected to begin in 2026. When completed in 2027, Thor will be able to produce enough electricity to supply more than one million Danish homes.

Thor will be the first offshore wind farm in the world where the turbine steel towers are manufactured with a significantly lower carbon footprint than usual. In addition, half of the turbines will be equipped with recyclable rotor blades.

Thor offshore wind farm, which will have a capacity of 1,080 megawatts, is a joint project of RWE (51%) and Norges Bank Investment Management (49%). RWE is in charge of the construction and operations throughout the lifecycle of Thor offshore wind farm.

A global leader in offshore wind

RWE already has 19 offshore wind farms in operation globally, including Rødsand 2, located south of the Danish island of Lolland. In addition to Thor in Denmark, the company is currently building three major offshore wind farms: the Sofia offshore wind farm (1.4 GW) in the UK, the Nordseecluster (1.6 GW, RWE share: 51%) off the German coast and OranjeWind (795 MW, RWE share: 50%) in the Netherlands.
