SSEN Transmission has selected Sumitomo Electric and Van Oord as preferred bidders for the Shetland 2 525kV high voltage direct current (HVDC) subsea cable project.
Shetland 2 is to connect 330km between Shetland and mainland to bring 2GW of renewable electricity to GB network, which forms part of the latest GB wide strategic transmission network plan “Beyond 2030”, where £5bn of investment by SSEN is expected in the north of Scotland by 2035.
Sumitomo Electric has also announced construction of its subsea cable factory.
The factory, located in the Scottish Highlands, will supply “critical elements” for the reinforcement of the UK electricity transmission grid and for connecting renewable energy production facilities to the grid.
The factory will be commissioned in 2026.
Sumitomo Electric held a groundbreaking ceremony at the site at the Port of Nigg, inviting key stakeholders including leading representatives from the UK and Scottish Governments.
During the event SSEN Transmission made the announcement for the Shetland 2 project.

“Backed with £24.5m of public sector funding, this will be Sumitomo’s first cable factory in Europe and the first HVDC cable factory in the UK, creating hundreds of jobs.
“The fast-growing offshore wind industry offers significant opportunities to attract inward investment and unlock wider economic benefits, not least in our transformational Green Freeports.
