Ørsted Installs Substation for Gode Wind 3 Offshore Wind Farm in Germany

The offshore substation at Gode Wind 3 Offshore Wind Farm was successfully installed 30 km off the island of Norderney. Here, all the energy produced by the 23 wind turbines will be collected and converted.

The offshore substation (OSS) installation for the Gode Wind 3 (GOW03) offshore project was successfully completed. The installation work for the foundations of the wind turbines for the Ørsted wind farm, which is under construction around 30 km off the island of Norderney.

Peter Johannesen, Project Manager and responsible for the substation in the GOW03 project: “This is an essential next step for our new German projects. Having the heart of Gode Wind 3 installed, for the first time on a monopile in one of our German wind farms, is a great success. This was only possible thanks to a great team effort and fantastic international collaboration with our partners at Chantiers de l'Atlantique and Jan De Nul.”

The substation built by the French construction company Chantiers de l'Atlantique was transported by barge and tug from the port of Saint-Nazaire on the west coast of France to Delfzijl in the Netherlands around three weeks ago. From there we went to the construction site, which is about 50 km from Norden-Norddeich, the location of the German operations management center in Ørsted.

Jan De Nul Group, the company contracted for the transport and installation, first installed the monopile foundation, on which the 1,900-ton substation was then placed. The park's 23 offshore wind turbines, each with an installed capacity of 11 MW and a total of 253 MW, will be connected to the OSS.

From the OSS, the transmission system operator TenneT will also establish a connection to the DolWin kappa converter station . The converter station was already installed in the sea in September 2022. In cooperation with Ørsted, the associated grid connection system DolWin6be tested at an early stage by providing electricity from the Gode Wind 1 wind farm. The two market leaders were able to make further progress in the process of expanding wind power at sea.

The alternating current produced in the offshore wind farm is converted into direct current and then transported on land to Hilgenriedersiel in East Frisia via a 45km long export cable connection. After further transmission on land and feeding into the high-voltage network in Emden/East, over 250,000 households can then be supplied with green electricity. The Gode Wind 3 wind farm is expected to be fully commissioned in 2024.

The spatial proximity to the existing Ørsted wind farms Gode Wind 1 and 2 allows synergies to be used in the operation and maintenance of the wind farms. Gode Wind 3 will be built in parallel with the Borkum Riffgrund 3 project (913 MW) this year and next year. In total, the two wind farms will then have an export capacity of over 1.1 gigawatts.

This doubles Ørsted's installed offshore wind power capacity in Germany to a total of around 2.5 gigawatts. Like Ørsted's existing offshore wind farms, the new projects will also be operated and maintained from Norden-Norddeich in East Frisia and Emden.
