Nexans has been awarded a multi-million euro contract by SSE Renewables to supply 800km of underground cables that will make the vital power connections for the Viking Wind Farm.
The wind farm on Shetland in the North Atlantic, 170km from the coast of Scotland, is scheduled to go online in 2024. With a peak output of 443MW, it will provide enough renewable energy for almost half a million homes and play a crucial role in helping Scotland achieve its net-zero targets.
The Viking Wind Farm will comprise 103 wind turbines set around the central mainland of Shetland. The 33 kilovolt (kV) underground cables supplied by Nexans will link the wind turbine arrays together and then export the power to the main substation for feeding into the interconnector that will transfer it to the UK grid.
The 650km of underground cables to be supplied by Nexans are a single core design with cross-linked polyethylene (XLPE) insulation. The conductors for the inter-array cables will be aluminium. Copper will be used to carry the higher current for the export cables. Nexans is also supplying 150km of bare copper earth cable.
The cables for the Viking Wind Farm will be manufactured at the Nexans Hellas plant in Lamia, Greece and will be supplied via Nexans UK.
