RWE has installed the first turbine at the 1100MW Thor offshore wind farm off the west coast of Jutland.
The Brave Tern vessel is handling installation from the Port of Esbjerg and can transport and install three turbine sets per cycle, the company said.
Seventy-two Siemens Gamesa turbines of up to 15MW each will be in place by the end of 2026.
Each unit stands about 148 metres above sea level and features 115-metre rotor blades, according to the announcement.
“Large-scale construction projects at sea require teamwork, precision, and a clear commitment to safety – qualities that our teams demonstrate every day at Thor. With the first turbine now installed, we have reached an important milestone in the delivery of Denmark’s largest offshore wind farm. Once fully commissioned, Thor will play a crucial role in achieving Denmark’s climate goals and in strengthening the EU’s energy independence,” said Sven Utermöhlen, chief executive officer RWE Offshore Wind.
Thor will be the first offshore wind farm to use 36 steel towers manufactured with a lower carbon footprint and will feature some recyclable blades.
RWE said offshore construction is progressing well, with the substation and all 72 foundations installed last year.
The project has secured a 30-year electricity production licence from the Danish Energy Agency, allowing commissioning works to start.
When fully operational in 2027, Thor will generate enough green electricity to supply more than one million Danish households and is expected to create 50 to 60 local jobs at a new RWE service building in Thorsminde.
Thor is jointly owned by RWE with 51% and Norges Bank Investment Management with 49%, with RWE responsible for construction and operations.
