French power cable giant Nexans is to design, manufacture and install the high voltage (HV) onshore and offshore export cables for the largest offshore wind farm in Scotland.
Construction on the 1GW (1075MW) Seagreen project, 27km off the coast of Angus, will start next year.
The three 20 km onshore export cables for the project will be manufactured at Nexans' factory in Charleroi, Belgium, while its factory in Charleston, South Carolina, will supply the three 65 km offshore export cables. This factory was recently expanded to manufacture HV subsea power cables and is currently the only facility with that capability in North America.
Nexans says it will work with local suppliers on subcontract opportunities available, including both the offshore and the land part of the contract from SSE Renewables.
The export cables for the Seagreen offshore windfarm project will be installed by the Aurora, Nexans' new cable laying vessel (CLV).The Aurora is currently under construction and will be delivered in the second quarter of 2021.
"We are delighted to receive this contract from SSE Renewables and we are excited to help bring the biggest windfarm in Scotland to life. This confirms Nexans' position as a strategic partner highly involved in the global energy transition," said Ragnhild Katteland, Nexans EVP for the Subsea and Land System Business Group.
The electricity generated by the Seagreen turbines will be transmitted via the subsea export cables to landfall at Carnoustie. Once ashore, the land cables will transmit the electricity to a new substation at Tealing where it will feed into the UK's national electricity transmission system.
