UK officials approved the construction of a $5.5 billion mainly underwater transmission line to send power generated by offshore wind from northeast Scotland to northern England – the largest project in of its kind in the country and the first of many high-speed electricity links planned with the aim of decarbonising its electricity system.
Work on the approximately 275-mile-long, 2GW Eastern Green Link 2 will begin this year and become operational in 2029, with about 40 miles to be buried underground.
Italy-based Prysmian Group will supply and install the cable, while a joint venture between Hitachi Energy and BAM will deliver converter stations at each end of the link. The project is owned by the joint venture Eastern Green Link 2 Ltd. of Scottish and Southern Electricity Networks Transmission and National Grid Electricity Transmission of England.

But fast tracking “doesn’t mean blank checks for developers, as we can step in and make financial adjustments,” he said. The government unit claims to have saved $100 million in upfront costs for the line’s developer.
With the project agreement signed, “we now look forward to working with our partners … on future projects, including the proposed [2-GW] Eastern Green Link 3,” said Sandy Mactaggart, Scottish and Southern Electricity Networks Transmission Director.
Ongoing work to develop a supply chain for the project will see the proposed line send power further down Britain’s east coast via a 340-mile submarine link.
