Riffgat — Emden/Borssum 155 kV HVAC export cable system for TenneT, single-circuit AC link, approx. 80 km total route (about 50 km submarine and 30 km land cable) connecting the Riffgat offshore wind farm to the German grid.
TenneT Offshore GmbH awarded NKT a turnkey contract for the Riffgat (NOR-0-1) offshore grid connection’s 155 kV HVAC export cable system. From 2011 to 2014, NKT planned and engineered the export cable system, manufactured the high-voltage submarine cable, and executed its offshore installation and final testing. The scope covered a single-circuit AC export link sized to transmit around 108–113 MW from the Borkum Riffgat offshore wind farm in the German North Sea to the German onshore transmission grid near Emden/Borssum. NKT’s order comprised approximately 51 km of 155 kV HVAC export cable and a cable route of about 48 km, delivered as a complete turnkey package including material production, cable-laying and commissioning of the export system for TenneT.
