RWE is has signed a Preferred Supplier Agreement with Siemens Gamesa for 72 units of its
SG 14-236 DD offshore wind turbines are planned to be installed at RWE’s 1,000 MW Thor offshore wind project. In addition, a service contract for the wind turbines is included. All deliveries are subject to RWE’s final investment decision.

Executives from RWE and Siemens Gamesa met at the Danish National Test Center for Large Wind Turbines in Østerild, Denmark yesterday to celebrate the signing. It was conducted only a few meters from the Siemens Gamesa SG 14-236 DD prototype machine.


The SG 14-236 DD is Siemens Gamesa’s flagship offshore wind turbine. It features a capacity of almost 15 MW and a 236 metre diameter rotor with a swept area of 43,500 square metres. Siemens Gamesa stated that this allows the SG 14-236 DD to provide an increase of more than 30% in Annual Energy Production (AEP) compared to its predecessor. It also features Siemens Gamesa’s patented IntegralBlades, each measuring 115 metres in length.

Sven Utermöhlen, CEO of RWE Offshore Wind, said: “With Thor, we will massively contribute towards Denmark’s ambitious climate targets. In order to deploy this offshore project, we will rely on our track record of more than 20 years in offshore wind and on experienced suppliers, like Siemens Gamesa, which are committed to working hand in hand with Danish supply chain companies and the local workforce. As RWE, we want to be one of the key drivers of offshore wind energy in Denmark.”

Marc Becker, CEO of Siemens Gamesa’s offshore business, said: “We’re thrilled to collaborate once more with RWE, and feel particularly encouraged by the signing of the Preferred Supplier Agreement for the Thor project. Our partnership already encompasses 12 offshore wind projects in both operation and development, totaling over 5.1 gigawatts of capacity in several countries. Connecting in Denmark today is a testament to our commitment to the country, and to the benefits we all gain from the Østerild test center. Governmental support in all aspects of the wind industry – from projects to support schemes to research and development centers like this one – is critical for our future success.”

With a planned capacity of around 1,000 MW, RWE’s is poised to be Denmark’s largest offshore wind farm to date. The wind farm will be built off the Danish west coast, approximately 22 kilometres from the Port of Thorsminde. Once fully operational, which is planned to be no later than 2027, Thor is expected to be capable of producing enough green electricity to supply the equivalent of more than one million Danish households.

For the operation and maintenance of the wind farm RWE will set-up a service base at the port of Thorsminde. RWE stated it intends to contribute to the local economy and community by creating up to 60 permanent jobs in the long-run. This includes technicians, engineers, nautical personnel as well as crew for the service vessels. It is expected that the new service station will be fully operational from 2026 onwards. RWE plans to support its wind farm for at least 30 years from this port.
