Siemens Gamesa signs Hornsea Project Two deal

UK: Siemens Gamesa Renewable Energy (SGRE) will supply turbines for Ørsted's 1,386MW Hornsea Project Two, 89km off the east coast of England.

This article was first published on 14 February 2018, when SGRE was awarded exclusive supplier status. On 28 June, SGRE and Ørsted officially signed the contract.

SGRE will provide 165 SG-8.0-167 DD turbines for what will the world’s biggest offshore wind farm when operational in 2022. The turbines will be rated at 8.4MW, with installation expected to begin in 2021.

The manufacturer will produce the majority (75%) of the blades and carry out pre-assembly work at its factory in Hull, north-east England, and also expects towers to be "partly sourced" from UK suppliers.

Siemens Gamesa added the nacelles for the turbines would be made at its new factory in Cuxhaven, northern Germany.

Ørsted has previously selected Siemens Gamesa as turbine supplier for several of its UK projects: Hornsea Project One, London Array, Race Bank, West of Duddon Sands, Walney Extension East and Westermost Rough.

The two have also teamed up for Anholt off the coast of Denmark, and Borkum Riffgrund 1 and Gode Wind 1 and 2, which are in German waters.

Siemens Gamesa unveiled the SG-8.0-167 DD model, which has a power-mode option to hit 9MW, at WindEurope’s annual conference in November.  It will also be used at Vattenfall’s Kriegers Flak in the Danish Baltic Sea and Vesterhav North and South projects.

The manufacturer claims the turbine’s 81.5 metre-long blades deliver an 18% wider swept area and 20% more annual energy output (AEP) than its predecessor, the SWT-7.0-154.

Ørsted had secured a contract for difference (CfD) support deal worth £57.50/MWh (€64.10/MWh) for Hornsea Project Two in the UK’s second auction round in September — a strike price 50% lower than those reached in an earlier round two years earlier.

Duncan Clark, Ørsted’s programme director for the project, said: "Hornsea Project Two is a game-changing renewable energy project in terms of both size and cost, and this selection is an important step in the procurement and construction process."

In February, the developer began work on a new operations hub in north-east England, from where it will serve its North Sea offshore sites, including Hornsea Project Two, and its 1.2GW Hornsea Project One site, currently under construction.


NKT has been chosen to supply more than 190 kilometres of far-shore export cables for Hornsea Two.

It will provide a 220kV high-voltage alternating current (AC) cross-linked polyethylene (XLPE) cable system for the site in the English North Sea.

The cable system will consist off three far-shore cables connecting the 165-turbine wind farm to the reactive compensation platform bringing the power towards land.

NKT added that the export cables will be manufactured in Karlskrona, Sweden, with production beginning in autumn 2018.

The Danish company added that the Hornsea Two contract, which it stated is worth €145 million, does not change its 2018 financial outlook. Announcing its 2018 first quarter results in May, NKT stated that it expects revenue to be between €1 billion and €1.1 billion and operating profit to be between €90 million and €110 million.

NKT is also providing the cables for Ørsted’s Hornsea One project, and delivered them in the first quarter of 2018.
