Hellenic Cables has been announced as the preferred supplier for the Nordseecluster. The up to 1.6-gigawatt (GW) cluster by RWE (51%) and Northland Power (49%) consists of four offshore wind farm sites in the German North Sea.

Hellenic Cables is to supply approximately 185km of 66kV aluminium and copper conductor cables to connect the 44 wind turbines with two offshore substations in Nordseecluster A (wind farms N-3.8 and N-3.7) and the 60 wind turbines of Nordseecluster B (wind farms N-3.6 and N-3.5) that will be directly routed into the transmission system operator’s converter.

Sven Schulemann, RWE’s Managing Director of the Nordseecluster, commented: “This agreement represents a crucial part of the Nordseecluster.  We expect to be fully operational at the beginning of 2029.  By then, we will generate enough green electricity to supply the equivalent of 1,600,000 German households every year and therefore make a significant contribution to Germany’s energy transition.”

Benjamin Miethling, Northland Power’s Managing Director of the Nordseecluster, added: “The use in offshore wind parks places particularly high demands on cables. We are glad to have signed this preferred supplier agreement with Hellenic Cables who are leading in this market. Through agreements like this, we also leverage the synergies during the development, construction, and subsequent operation of the four wind farm sites.”

The Nordseecluster will be constructed in two phases: Two wind farms (N-3.8 and N-3.7) with a combined capacity of 660 megawatts (MW) are currently in the permit application phase.  Cables for installation at sea are expected to be delivered towards the end of 2025, with commercial operations starting in early 2027 for Nordseecluster A.  Two further wind farms (N-3.6 and N-3.5) of the second phase (Nordseecluster B) will add an additional 900 MW of capacity. The delivery of cables for Nordseecluster B is scheduled for late 2027, with commercial operation to start beginning of 2029.  The cables will be produced at Hellenic Cables’ vertically integrated, state-of-the-art submarine cables plant in Corinth, Greece.

Kostas Savvakis, General Manager at Hellenic Cables, adds: “It is a great honour for Hellenic Cables to have been once again selected by RWE and Northland Power as the preferred supplier for a project – the strategic offshore wind cluster in the German North Sea (the Nordseecluster). We are looking forward to jointly contributing to the country’s energy transition by supplying green electricity through our technologically advanced cables.”

The Nordseecluster will be in close proximity to the existing 332 MW Nordsee One wind farm, which RWE and Northland Power co-developed and continue to operate jointly. In order to deploy the cluster, the partners will rely on experienced suppliers, like Hellenic Cables, and on their own expertise in offshore wind.
