Siemens Gamesa Turbines with Recyclable Rotor Blades: RWE Installs First Wind Turbine in Denmark’s Largest Offshore Wind Farm Thor

Essen (Germany) - The expansion of Denmark’s largest offshore wind farm, Thor, has reached a decisive milestone: the first of a total of 72 wind turbines has been successfully installed off the west coast of Jutland. The project, with a capacity of 1.1 GW (1,100 MW), is therefore on schedule for full commissioning in 2027.

Thor is a joint project of RWE (51%) and Norges Bank Investment Management (49%). RWE is responsible for construction and operation throughout the entire lifecycle.

Installation work is being carried out from the Port of Esbjerg. The specialized vessel Brave Tern transports and installs up to three turbine sets per deployment cycle. The 72 Siemens Gamesa turbines, each with a capacity of up to 15 megawatts, reach a height of around 148 meters above sea level, and the rotor blades are up to 115 meters long.

Thor is the world’s first offshore wind farm to deploy 36 turbines with CO₂-reduced steel towers from Siemens Gamesa. In addition, selected turbines will be equipped with recyclable rotor blades. These innovations reduce the environmental footprint across the entire lifecycle.

Last year, the offshore substation and all turbine foundations were successfully installed. The Danish Energy Agency has also granted a 30-year production license – a key prerequisite for the start of commissioning.
