Prysmian Group has won selection from SP Transmission plc and National Grid Electricity Transmission plc as the preferred bidder for the Eastern Green Link 4 (EGL4) HVDC cable project. The connection will link Scotland and England through the North Sea, improving the strength and reliability of the U.K.’s energy grid.
EGL4 plays a central role in boosting U.K. energy security and supporting the shift to low-carbon power. The project carries an estimated value of €2 billion, and both sides continue to finalize contract terms. Once operational, EGL4 will make cleaner and more affordable power more accessible nationwide.
The interconnector will stretch roughly 646 km, including a 530 km subsea cable between Kinghorn, Fife, and Anderby Creek or West Norfolk. Additional underground cable sections onshore will complete the system. The project will create stronger north-south links and help integrate more renewable power into the national grid.
Prysmian already leads major interconnector projects across the region. The company delivered Eastern Green Link 1 and 2 and the Viking Link Project, the world’s longest high-voltage underground and submarine interconnection. These projects emphasize Prysmian’s expertise in reliable HVDC technology and sustainable energy infrastructure.
