ZAMUDIO, Spain Vattenfall has named Siemens Gamesa the nominated preferred supplier 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 and 72 km (29 and 45 mi) 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 is subject to the UK government’s Contract for Difference Round 4 auction award in 2022 and subsequent final investment decision by Vattenfall.

Also, Siemens Gamesa’s latest wind turbine features a 236-m (774-ft) diameter rotor using IntegralBlades, with a 43,500-sq m (468,230-sq ft) swept area. This, according to the company, 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. In addition, the machine can reach 15 MW capacity with the company’s Power Boost function.

The prototype SG 14-222 DD machine has been installed at the Danish national test center for large wind turbines in Østerild, Denmark. Final commissioning and full operation are expected before the end of 2021. The SG 14-236 DD prototype is expected to be installed in 2022 and commercially available in 2024.

In addition, Siemens Gamesa has signed a memorandum of understanding to license its 11-MW Direct Drive offshore technology to China Energy United Power.
