Britain's First Subsea Cable Factory Just Opened in the Highlands. Its 250 Jobs Are Still a Promise.
Estimated reading time: 4 minutes
In short. Sumitomo Electric opened a GBP350 million factory at Port of Nigg, Ross-shire, on 19 October 2026, the UK's first plant built to manufacture high-voltage direct current subsea cables [1]. The company says the site will create up to 250 direct jobs, with more than 400 further roles supported across the wider UK supply chain [2]. The factory is open; the jobs figure is not yet delivered. This ledger logs 250, graded ANNOUNCED, status promised, region Scotland, and sets review dates for October 2027 and October 2028 to check the actual headcount against it.
What opened this week
First Minister John Swinney and Scottish Secretary Douglas Alexander were at Port of Nigg on Monday for the opening of a factory Sumitomo Electric has spent GBP350 million building: the UK's first plant making high-voltage direct current cables for the subsea links that carry power from offshore wind farms to shore [1]. Swinney called it an investment that "brings them those opportunities very close to home," and Europlan managing director Donnchadh Campbell, whose firm worked on the project, put it more plainly: "It's been a long journey, I think it's a big day for Sumitomo, a big day for the Highlands" [3].
The site sits inside the Inverness and Cromarty Firth Green Freeport, which carries its own tax and customs advantages, and the Scottish Government put GBP24.5 million of public money behind the project [2]. The factory's first contracts are already named: the Shetland HVDC Link 2 and the SeaLink HVDC Link, both grid connections for Scottish offshore wind [3]. Thirteen Scottish workers travelled to Sumitomo's operations in Japan to train on the cable-making process before the plant switched on, and UHI Inverness ran a parallel training programme for local recruits [3]. AI is not mentioned anywhere in the coverage of this opening; the jobs on offer are skilled manufacturing roles, not roles AI is credited with creating or threatened with removing.
What is a promise and what is a fact
Here is what has actually happened: a GBP350 million factory exists, it opened on 19 October 2026, and it is making cable. Here is what has not happened yet: 250 people do not yet work there. "Up to 250 direct jobs will be created" is Sumitomo's own forecast, made at an opening ceremony surrounded by two government ministers, not a headcount anyone has published [2]. The further 400-plus jobs across the supply chain are vaguer still: no single employer, no single site, no date this ledger can check them against, so they are noted here and logged nowhere.
None of this makes the 250 figure unlikely. A plant this size, with named contracts already signed and a training pipeline already running people through Japan and UHI Inverness, has done more of the groundwork than most announcements this ledger sees. But groundwork is not the same as a payslip, and a factory that genuinely opens this week with genuinely promised jobs attached is exactly the case this ledger's first rule exists for: announced is not delivered, however solid the announcement looks.
How the ledger logs it
A gain of 250, graded ANNOUNCED, status promised, sector manufacturing, region Scotland. The review clock starts from the opening date, 19 October 2026, with checks due in October 2027 and October 2028 against the actual headcount at the Nigg site. If Sumitomo publishes a jobs number at either point, delivered or short, this entry updates to match it.
What happens next in this ledger
The test is simple and specific: does Port of Nigg employ 250 people making subsea cable within the next two years. A factory that is already running and already has contracts to fill gives this promise better odds than most that pass through here. Better odds are not a count. This ledger will check back.
