The project will be executed in two phases, Nordseecluster A and B, with the former comprising 660MW and the latter adding 900MW.

Nordseecluster A’s construction at sea is set to commence next year, with the manufacturing of some essential components already underway.

This phase is expected to see all 44 wind turbines connected to the grid by early 2027.

RWE offshore wind CEO Sven Utermöhlen said: “Our portfolio already includes six offshore wind farms off Germany’s coastlines. The Nordseecluster will add two more. This sends out a good signal for the energy transition in Germany and for RWE.

“With a total capacity of 1.6GW, these wind farms will generate around 6.5TWh of green electricity per year. This will contribute in particular to the decarbonisation of industry in our home market.”

The German Federal Network Agency has exempted RWE from lease payments for the Nordseecluster sites.

The green electricity produced from the Nordseecluster will aid RWE’s industrial clients, including AI data centre operators, in their decarbonisation efforts through tailored energy solutions.

Key suppliers for the Nordseecluster have also been appointed.

Atlantique Offshore Energy will provide two offshore transformer substations, while Hellenic Cables is responsible for cable production.

Dajin Offshore will manufacture the wind turbine foundations, with Van Oord handling their sea installation.

Vestas has been selected to supply the V236-15.0 MW wind turbines, each with a 15MW capacity. Havfram Wind will oversee the transport and installation of the turbines using the vessels ‘Norse Wind’ and ‘Norse Energi.’
