RWE and Northland Power have selected Hellenic Cables as the preferred supplier for their Nordseecluster of four offshore wind farms.
Hellenic Cables will supply approximately 185km of 66-kV aluminium and copper conductor cables for the projects in the German North Sea, which will have a combined capacity of up to 1.6GW.
These will 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.
N-3.8 and N-3.7 will have a combined capacity of 660MW. Currently in the permit application phase, installation of cables at sea is expected to be delivered towards the end of 2025, with commercial operations starting in early 2027.
N-3.6 and N-3.5 will provide an additional 900MW of capacity. Delivery of cables for Nordseecluster B is scheduled for late 2027 with commercial operation to start at the beginning of 2029.
Sven Schulemann, RWE Managing Director of the Nordseecluster, said: “This agreement is crucial for 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.”
Kostas Savvakis, General Manager at Hellenic Cables, added: “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.”
