Siemens Gamesa has been named Preferred Supplier by Vattenfall for its 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.

The agreement concerns Vattenfall’s Norfolk Vanguard and Norfolk Boreas projects located between 47 and 72 km off the English east coast. Each site 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,” said Catrin Jung, Head of Business Unit Offshore at Vattenfall.

The projects will feature Siemens Gamesa's latest turbine model, the SG 14-236 DD. The turbine features a 236-metre diameter rotor using Siemens Gamesa IntegralBlades, with a 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 according to Siemens Gamesa. Furthermore, it claims 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 are 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.

“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,” said Marc Becker, CEO of the Siemens Gamesa Offshore Business Unit. “Developing an even larger rotor for our flagship offshore wind turbine is an example of how we are always seeking to innovate and improve. We can increase blade length and incorporate the solution on our existing design. We are committed to leading the offshore revolution, adding value to our customer’s projects and unlocking the potential of wind power.”

Siemens Gamesa's facility in Hull is the largest offshore wind manufacturing facility in the UK. The company recently announced an investment of £186 million to double the size of the facility by over 41,000 square meters, adding approximately 200 jobs to the approximately 1,000 jobs already present. This expansion is expected to enable manufacturing of next-generation offshore wind turbine blades. Approximately 500 persons are directly employed in Siemens Gamesa’s UK offshore service functions, supporting operations and maintenance of the more than 1,800 Siemens Gamesa offshore wind turbines installed in UK waters.
