UK Launches Offshore Wind Cable Testing Site to Accelerate National Production

The Offshore Renewable Energy (ORE) Catapult is launching a new offshore wind cable testing facility in Blyth, North East England. This initiative, supported by a GBP 2.1 million (approximately EUR 2.4 million) investment from the North East Combined Authority, aims to enhance the UK’s offshore wind production capabilities.
Investment Details and Facility Features
The funding will enable ORE Catapult to construct a high voltage (HV) electrical test facility. This specialized site will feature bespoke equipment designed for pre-qualification testing of HV cable systems.
- High Voltage Testing: The facility will simulate real-world conditions by applying extreme voltages and currents to the cables.
- Varied Testing Environments: Cables will be tested in different conditions, including being buried, ducted, and submerged in saltwater.
- Improved Reliability: This facility is expected to enhance the reliability of cable systems and accelerate production timelines for new technologies.
Strategic Importance for the UK Offshore Wind Industry
Currently, there are no similar testing facilities in the UK. This gap in resources hampers the development of offshore wind technologies. Alex Neumann, Chief Engineer in HV Electrical at ORE Catapult, emphasized the significance of this development for both local and national supply chains.
- “This facility will keep the Blyth site at the forefront of testing.”
- “It will facilitate rapid growth in offshore wind technology essential for the future,” Neumann stated.
Collaboration with Cable Manufacturers
ORE Catapult plans to collaborate with various organizations in the cable manufacturing sector, both domestically and internationally. JDR Systems has already committed to utilizing the new facility.
Timeline for Opening
The opening of this state-of-the-art testing facility is anticipated for late 2026. This initiative underscores the UK’s commitment to advancing offshore wind cable technology and enhancing the nation’s energy infrastructure.
