Scottish Renewables, the UK subsidiary of Spanish renewables giant Iberdrola, chose Siemens Gamesa to supply the turbines after securing a power deal for 100% of the East Anglia Three project from the UK government in the fourth round of a contracts for difference tender (Cfd4) last year.
The company is developing four offshore wind projects with a combined capacity of 3.1GW in the East Anglia Hub development in the North Sea.
The 714MW East Anglia One, 800MW East Anglia One North, and 900MW East Anglia Two projects are also part of the hub owned entirely by Scottish Renewables.
East Anglia Three is a 1.4GW wind farm 75km off the coast of Suffolk in the UK North Sea according to Windpower Intelligence, the data and research division of Windpower Monthly.
Siemens Gamesa said today (Wednesday) that it had also agreed an eight-year service contract to accompany the supply of its largest offshore model, the SG 14-236 DD turbine, which have an individual capacity of over 14MW.
Siemens Gamesa dubbed East Anglia Three the world’s “second largest” offshore wind farm.
A spokesperson for the company told Windpower Monthly that Siemens Gamesa and other wind industry players were calling on the UK government to lift the electricity generator levy, a temporary 45% tax on excess generation receipts, which was introduced after Scottish Renewables won the power deal for East Anglia Three in last year's CfD4 tender.
Scottish Renewables expects installation at East Anglia Three to begin in spring 2026 and to be completed, with the wind farm producing power, by the end of 2026.
The project will use a grid connection solution that Siemens Gamesa said would convert alternating current produced by their turbines at sea into direct current for low-loss transmission to the coast, before a second convertor switches the electricity back to alternating current for connection to the grid.
