Siemens to supply world’s second-largest offshore wind array

4 April 2023

Siemens Gamesa has signed a firm order with ScottishPower Renewables to supply 95 units of its flagship SG 14-236 DD wind turbine to the East Anglia 3 wind power project in the North Sea, off England’s east coast, with a total capacity of 1.4 GW. Also included is a service contract, initially for an eight-year period. The development marks an important step on the UK’s path to decarbonisation of the energy system, and the first installation of the SG 14-236 DD in the country.

East Anglia 3 is the second of four projects planned in the ScottishPower Renewables 2.9 GW East Anglia Hub development in the North Sea. The project will cover an area of approximately 305 km², at its closest point 69 km from the Norfolk coast, in the northern part of the East Anglia zone. Once completed, it will be the second largest offshore wind power plant in the world. Installation is anticipated to begin in spring 2026 and to be completed by the end of that year. 

Siemens Gamesa Offshore CEO Marc Becker commented: “East Anglia 3 … marks the first deployment of the ground-breaking SG 14-236 DD offshore wind turbine in UK waters.”

The grid connection will be supplied by Siemens Energy. Under its contract, Siemens will build an AC/DC converter substation out at sea and a second converter on shore.

The anticipated lifetime of the project is 25 years, and from 2026 it will take power generation from the East Anglia 3 development beyond the UK’s 2050 net-zero target. The prototype of the flagship SG 14-236 DD model recently generated its first power at the Østerild Test Centre in Denmark.
