CHARLESTON, South Carolina and PARIS – SSE Renewables has contracted Nexans to design, manufacture, and install the high voltage onshore and offshore export cables for Phase 1 of the Seagreen wind farm project offshore Scotland.
Nexans’ factory in Charleston, South Carolina, will supply the three 65-km (40-mi) 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.
The three 20-km (12-mi) onshore export cables will be manufactured at the company’s factory in Charleroi, Belgium.
The company’s new cable laying vessel Aurora will install the export cables. The vessel is under construction and is expected to be delivered in 2Q 2021.
Construction on the 1,075-MW Seagreen project, which is 27 km (17 mi) off the coast of Angus, is expected to start next year. When completed in 2022/23, Seagreen 1 will be Scotland’s largest wind farm and is expected to power 1 million homes.
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 in to the UK’s national electricity transmission system.
