Wind energy – wind turbines
Siemens Gamesa has been named Nominated Preferred Supplier by Vattenfall for the 3.6 GW Norfolk offshore wind power projects in the UK.

The agreement includes the potential deployment of the new SG 14-236 DD offshore wind turbines and a multi-year Service agreement. Located between 47 – 72 km off the English east coast, the agreement encompasses Vattenfall’s Norfolk Vanguard and Norfolk Boreas projects. Each park has a capacity of 1.8 GW.
The nominated preferred supplier agreement between Siemens Gamesa and Vattenfall is subject to the UK Government’s Contract for Difference Round 4 auction award in calendar year 2022 and subsequent final investment decision by Vattenfall.
“Vattenfall’s Norfolk projects will form one of the largest offshore wind zones in the world when they are completed, generating enough renewable electricity to power the equivalent of 4 million homes. We’re very pleased to be able to announce Siemens Gamesa as the Nominated Preferred Supplier for Norfolk Vanguard and Norfolk Boreas. We want to accelerate fossil free living in an affordable way for our customers, and we are always aiming for the right partners to make this happen. I am looking forward to the next steps on this grand journey,” says Catrin Jung, Head of Business Unit Offshore at Vattenfall.
The newest Siemens Gamesa wind turbine features a 236-meter diameter rotor using Siemens Gamesa Integral Blades, with an astounding 43,500 m2 swept area. This allows the SG 14-236 DD to provide an increase of more than 30% in Annual Energy Production compared to the SG 11.0-200 DD offshore wind turbine. Furthermore, the machine can reach an impressive 15 MW capacity including the company’s Power Boost function. As it is built on sound technology, the new machine otherwise remains unchanged in relation to the SG 14-222 DD offshore wind turbine.
The prototype SG 14-222 DD machine has already been installed at the Danish National Test Center for Large Wind Turbines in Østerild, Denmark. Final commissioning and full operation is expected before the end of calendar year 2021. This milestone will greatly expedite the installation of the SG 14-236 DD prototype in calendar year 2022.
