The Nordseecluster will be constructed in two phases, Nordseecluster A and Nordseecluster B, each comprising two offshore wind farms.

The sites of Phase A (the 225MW NC 1 and the 435 MW NC 2) are currently in the permit application phase. RWE was awarded the contract by the Federal Network Agency for the two sub-areas of Phase B (the 420 MW NC 3 and the 480 MW NC 4).

The steel-cutting milestone took place ten months after RWE announced the order to Atlantique Offshore Energy for two substations for the Nordseecluster A wind farms.

The company was selected to design, construct, install, and commission the offshore substations for the first phase.

The substation jackets will be built by Italy-headquartered Rosetti Marino under a contract signed with Chantiers de l’Atlantique in September 2023.


Located 35 kilometres north of Juist Island and 55 kilometres off the German Coast, the Nordseecluster A offshore wind farms will comprise a total of 44 Vestas 15 MW wind turbines and are scheduled for commercial operation in early 2027.

The second phase Nordseecluster B will add 900 MW of capacity installed across two more wind farms. Nordseecluster B is scheduled for commissioning in 2028/2029.
