Siemens Gamesa has won a firm order from utility Innogy to supply turbines for the 342MW Kaskasi project near the German North Sea island of Heligoland.
The German-Spanish OEM will supply 38 of its SG 8.0-167 DD Flex turbines for the project, it said in a note to the Spanish stock market regulator.
Installation work is planned to start in mid-2022. The order includes a two-year service contract.
Innogy had won Kaskasi in Germany’s second offshore wind auction in 2018, with a bid price above the average winning price of €46.60 ($50.98).
Innogy’s generation assets later this year will be transferred back to former parent RWE in the wake of a wide ranging share and asset swap deal with rival E.ON.
The utility said that the contract value for wind turbines and foundations, the offshore transformer substation and the cabling for the wind farm nears €500m ($539.6m).
"Offshore wind is an important pillar to reach Germany's climate protection goals by supplying green electricity from a reliable source," Innogy chief operating officer Christoph Radke said, adding that Kaskasi is the company's third project to be built in German waters.
"Our investment in this project underlines our ambitions to further grow in offshore wind in Europe and around the globe."
Sven Utermöhlen, Senior Vice President Renewables Operations Offshore at Innogy, added: "Following our success in the German offshore auction in 2018, we have now taken the next important step in realising Kaskasi offshore wind farm. With Siemens Gamesa, Bladt Industries and Seaway 7 we have brought extremely experienced contractors and suppliers on board for all key components and their installation, which is expected to start next year."
Innogy has chosen Bladt Industries for the delivery of 39 monopile foundations, 38 transition pieces and one transition piece special designed for the offshore substation.
“It is clearly an advantage for the project, that we have been able to provide guidance and inputs to ensure the most optimised fabrication design," Bladt Industries chief executive Klaus Steen Mortensen said.
"This early involvement has been an productive process for both parties and I am convinced that it will pay off in the end."
Bladt Industries are also to deliver the offshore substation (in an EPCI contract), including the transition piece, for Kaskasi. The contract will be executed in close cooperation with the company's long-term partners Semco Maritime and ISC Engineering.
