JDR adds £20m as its new offshore-wind cable plant ramps up
JDR Cable Systems has added £20m of equity as it ramps up a major new manufacturing site for the offshore-wind industry.
The investment comes shortly after JDR's £130m factory in Cambois, near Blyth, began operations. The 69,000-square-metre site is designed to manufacture the high-voltage subsea cables needed to connect larger offshore wind farms, and represents one of the most significant recent additions to the UK's offshore-energy supply chain.
A major increase in UK cable capacity
JDR makes subsea power cables and umbilical systems used to carry power, data and control signals in offshore energy projects. Its new Cambois facility includes the UK's only quayside high-voltage continuous catenary vulcanisation line, allowing long cable sections to be manufactured and loaded directly onto installation vessels.
The company says the site will more than triple its existing production capacity. It also expands JDR's range into higher-voltage and longer-length cables at a time when larger turbines and projects further from shore are putting new demands on transmission technology.
That technology is already moving forward. In 2025, JDR completed qualification testing for a 132kV static array cable, twice the voltage of the 66kV systems widely used in offshore wind today. Higher voltages allow more power to move between turbines and can help reduce the amount of cabling required for a project.
What the £20m investment tells us
The latest share issue comprises roughly 244,000 ordinary shares at £82.05 each, with total consideration of £20m. JDR is part of Poland's TFKable Group, which acquired the business in 2017, and the public record does not identify the subscriber. The transaction should therefore be read as fresh equity supporting the company rather than a disclosed third-party funding round.
JDR employed 527 people in its latest accounts. Its CompanyTrack profile shows the wider expansion story, including recent growth in headcount and repeated additions to its equity base.
For the wider market, the investment is another sign that offshore wind's next phase is as much a manufacturing challenge as a project-development one. Turbines can only be deployed at scale if suppliers can produce the high-voltage cables, foundations and installation equipment needed to connect them.
JDR's £20m was the largest priced capital addition identified in our July UK funding and investment roundup.
