New SiemensGamesa Turbine for Vattenfall’s Big UK Offshore Wind Farms

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.

“The Siemens Gamesa – Vattenfall partnership has been fruitful for a great number of years across numerous markets. With this Nominated Preferred Supplier agreement for the Norfolk projects, we aim to add another 3.6 GW to our joint portfolio,” says Marc Becker, CEO of the Siemens Gamesa Offshore Business Unit.

“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 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,” says Catrin Jung, Head of Business Unit Offshore at Vattenfall.

Siemens Gamesa has a significant presence in the UK wind industry, with its facility in Hull being the largest offshore wind manufacturing facility in the country. The company recently announced an investment of £186 million to double the size of the facility by over 41,000 square meters. More than 1,800 Siemens Gamesa offshore wind turbines are installed in UK waters.

New SG 14-236 DD offshore wind turbine

The newest Siemens Gamesa wind turbine features a 236-meter diameter rotor using Siemens Gamesa IntegralBlades, with a 43,500 m2 swept area. This is said to allow 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 a 15 MW capacity including the company’s Power Boost function.

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.

Patented Siemens Gamesa RecyclableBlades will be available as options for customers selecting the SG 14-236 DD machine. The world’s first recyclable wind turbine blades ready for commercial use offshore have already been produced.
