The Nordseecluster combines wind farm sites in the eastern part of the German North Sea into a 1.6 GW project. The combination of those sites opens up unique economies of scale – making the whole of Nordseecluster more than the sum of its parts.
The Project
The Nordseecluster combines wind farm sites in the eastern part of the German North Sea. With a total capacity of up to 1.6 GW the Nordseecluster will generate enough green electricity to supply the equivalent of 1,600,000 homes. The Nordseecluster will be constructed in two phases: For Nordseecluster A (NC 1 and NC 2), first foundations have been offloaded and stored at the marshalling port in Eemshaven. Construction at sea is scheduled to begin in summer 2025. The installation of the wind turbines is scheduled for 2026. By the beginning of 2027, all wind turbines should be fully connected to the grid. Nordseecluster B (NC 3 and NC 4) is scheduled to start commercial operation from the beginning of 2029.
The Nordseecluster is located approximately 50 km north of the island of Juist. This area in the German Bight is dedicated to offshore wind. Our project is in the most southerly row of offshore projects within the EEZ (Exclusive Economic Zone) and is bordered to the north and south by the main shipping traffic separation routes.
The Nordseecluster is a joint offshore wind project of RWE (51%) and Norges Bank Management Investment (49%). RWE is in charge of construction and operations throughout the lifecycle of the Nordseecluster offshore wind farms.

Norges Bank Investment Management
Norges Bank Investment Management is the asset management division of Norges Bank, the Norwegian central bank. As manager of the Government Pension Fund Global, its mission is to safeguard and build financial wealth for future generations in Norway. The fund is invested globally in equity, fixed income, real estate and renewable energy infrastructure. It had investments worth 18,524 billion Norwegian kroner, or approximately 1,600 billion euros, as of 31 March 2025.
Development
The close proximity of the offshore sites offers the opportunity to develop one of the largest offshore wind farms in Germany – The Nordseecluster.
The merger of the sites offers economies of scale and allows the development of the Nordseecluster B of the project (NC 3 and NC 4) together with the Nordseecluster A (NC 1 and NC 2). All major contracts are made for both phases of the project, allowing the supply chain to reliably plan manufacturing and leverage synergies to be cost efficient.
Experienced suppliers selected for RWE’s Nordseecluster
RWE has chosen experienced supply chain partners to implement its Nordseecluster: Atlantique Offshore Energy, the marine energy business unit of French company Chantiers de l’Atlantique, is the supplier for two electrical offshore substations. Hellenic Cables was selected for the cable manufacturing. The monopile foundations for the wind turbines will be manufactured and delivered by Dajin Offshore and installed offshore by the Dutch company Van Oord. Vestas has been selected to deliver a minimum of 104 offshore wind turbines (Type: V236-15.0 MW), with a capacity of 15 MW each. The Norwegian company Havfram Wind will transport and support the installation of the turbines, which is expected to start in 2026 for Nordseecluster A, with commercial operation launching in early 2027. Turbine installation works for Nordseecluster B are scheduled to begin in 2028 with commercial operation to start at the beginning of 2029.
A new warehouse is being built in Eemshaven to support the operations of the Nordseecluster
The Dutch division of Clarkson Port Services will build a new warehouse facility in the port of Eemshaven. The new building, approximately 1,700 square metres in size, will be located in the Beatrixhaven on the premises of Clarkson Port Services. Construction of the new storage hall with adjoining office facilities is to start this summer, and it is expected to be completed in spring 2026. RWE will take a long-term lease on the new facility to support the operations and maintenance of the Nordseecluster. In addition, Clarkson Port Services deliver logistics and port services for the project.
Key factors
Why the Nordseecluster sets new standards:
Development
The close proximity of the offshore sites offers the opportunity to develop one of the largest offshore wind farms in Germany.
Capacity
The total capacity of the cluster will be up to 1.6 GW. This leads to a total annual power production of 6.400.000 MWh. This is enough to supply 1.600.000 average households with renewable energy.
Turbines
A minimum of 104 offshore wind turbines are planned to be installed north of the island of Juist. Each of the innovative, state of the art turbines will have a capacity of 15 MW.
