Siemens Gamesa's 14-MW turbine eyed for 3.6-GW Norfolk offshore wind zone

Siemens Gamesa Renewable Energy SA (BME:SGRE) is in line to supply turbines to Swedish utility Vattenfall AB for its 3.6-GW Norfolk offshore wind power development in UK waters.

Vattenfall named the turbine maker its nominated preferred supplier for the Norfolk Vanguard and Norfolk Boreas projects, each of 1.8 GW of capacity, Siemens Gamesa announced on Monday.

Under the nominated preferred supplier contract, the projects are expected to use the new 14-MW SG 14-236 DD offshore wind turbines, and benefit from a multi-year service agreement.

The contract is subject to Vattenfall securing the award for Norfolk in the UK government’s contract-for-difference round 4 auction in 2022, and taking the final investment decision afterwards, Siemens Gamesa said.

The SG 14-236 DD prototype is planned for installation in 2022. The new machine features a 236-metre (774.3 ft) diameter rotor using Siemens Gamesa IntegralBlades, and can sweep an area of 43,500 square metres (468,230 sq ft). With the Power Boost function, the turbine can hit 15 MW of capacity.

The new 14-MW model shares technology with its predecessor, the SG 14-222 DD, the prototype of which is already installed at the Danish National Test Center for Large Wind Turbines in Denmark. The final commissioning and full operation of the SG 14-222 DD will expedite the installation of the SG 14-236 DD prototype, the turbine maker said.

The SG 14-236 DD machine is expected to be commercially available in 2024.
