The government will continue efforts to create jobs, spur growth, and solidify Scotland's status as the top destination for investment outside London.

Sumitomo Electric opens £350 million UK subsea cable factory to support offshore wind and grid expansion. 21 October 2026 Estimated reading time: 5 minutes Sumitomo Electric Industries has officially opened the United Kingdom's first high voltage direct current (HVDC) subsea cable manufacturing facility at the Port of Nigg in Scotland, marking a £350 million investment aimed at expanding domestic cable production, supporting offshore wind development and strengthening electricity transmission infrastructure. The opening ceremony, held on October 19, 2026, establishes a new manufacturing base in the Scottish Highlands at a time when Britain is preparing major investments in offshore transmission networks and renewable energy connections. The factory will manufacture 525 kV cross linked polyethylene (XLPE) HVDC subsea transmission cables and subsea inter array cables, providing equipment required for offshore wind farms, electricity interconnectors and long distance power transmission. New manufacturing capacity at the Port of Nigg. The facility occupies a 15 hectare site within the Inverness and Cromarty Firth Green Freeport, with approximately 58,000 square metres of manufacturing floor space. Its location at the Port of Nigg provides access to established maritime infrastructure in a region already supporting offshore energy construction and logistics operations. For the project cargo and maritime sectors, the investment introduces another industrial manufacturing facility requiring specialist transport, heavy handling equipment, cable storage and marine logistics services. Subsea transmission cables are particularly demanding cargoes. Their weight, dimensions and minimum bending radius require specialised handling systems, while offshore installation projects depend on coordinated manufacturing schedules, port availability and cable laying vessels. Producing these cables in Scotland could reduce reliance on overseas manufacturing for selected UK transmission projects, although the company has not disclosed the factory's annual production capacity. The facility is expected to create more than 200 direct skilled jobs and support over 400 jobs across the wider UK supply chain. Workforce development includes operator training in Japan and a programme designed to transfer technical knowledge to locally recruited employees. £350 million investment supports UK electricity infrastructure. The factory forms part of a broader effort to expand electricity transmission capacity as offshore wind generation increases around the British coastline. HVDC technology allows large quantities of electricity to travel long distances with relatively low transmission losses, making it particularly suitable for offshore wind connections and subsea interconnectors. The practical challenge is straightforward: generating more offshore electricity provides limited benefit unless transmission networks can deliver that power to consumers and industrial users. Osamu Inoue, President of Sumitomo Electric, said the facility would support Britain's electricity infrastructure and renewable energy development. "This factory will serve as a vital production base supporting the strengthening of the UK's transmission infrastructure, the expansion of renewable energy deployment, and the delivery of a stable and reliable energy supply for generations to come." The project was first announced in April 2023, with construction beginning following a groundbreaking ceremony in May 2024. Scottish government backs industrial investment. The Scottish Government contributed £24.5 million towards construction of the factory, while the wider Green Freeport initiative has received £25 million in UK Government seed funding. Factory Tour John Swinney, Scotland's First Minister, described the development as an investment in the region's manufacturing capabilities and skilled workforce. "This facility puts Scotland right at the heart of the energy transition and is a strong vote of confidence in our people, skills and engineering excellence." Douglas Alexander, Secretary of State for Scotland, highlighted the importance of combining port infrastructure, engineering expertise and industrial investment. The facility also reflects government efforts to establish more domestic manufacturing capacity for equipment needed to expand Britain's electricity network. Transmission projects provide demand for subsea cables. Major transmission developers have already identified projects that could benefit from the new manufacturing capacity. SSEN Transmission said its proposed Shetland 2 subsea cable project had helped provide an initial commercial foundation for the investment. Managing Director Rob McDonald said the company planned to invest approximately £29 billion over the next five years. He said further investment in manufacturing would depend partly on greater certainty around electricity network development, planning decisions and long term renewable energy policy. Meanwhile, National Grid has awarded Sumitomo Electric a contract to supply HVDC cable for its Sea Link project. The electricity network operator said it had established more than £28 billion in UK supply chain contracts to support future infrastructure development. Carl Trowell, National Grid's Executive President of Global Capital, said the new factory demonstrated how long term infrastructure investment could support domestic manufacturing. New opportunities for cable logistics and offshore installation. The Port of Nigg facility adds a manufacturing element to Scotland's existing offshore energy supply chain, potentially increasing demand for specialist logistics services linked to cable production and installation. HVDC subsea cable projects typically involve large cable drums, dedicated handling equipment, specialised transport arrangements and complex vessel loading operations. The logistics requirements can extend from factory production and testing through storage, quayside handling, marine transport and offshore installation. For ports and project freight operators, manufacturing schedules and installation vessel availability remain important factors in determining how efficiently these operations can be organised. Sumitomo Electric has not announced specific arrangements for cable loading, storage capacity or maritime transport services associated with the new plant. The company said it intends to use the Scottish facility to support offshore wind and interconnector projects across Europe, extending its existing subsea cable manufacturing and engineering activities.
