The UK’s transmission operators, SP Transmission and National Grid Electricity Transmission, have selected the Italian cable maker Prysmian as the preferred bidder for the Eastern Green Link 4 (EGL4) high-voltage direct current (HVDC) cable interconnector project in the United Kingdom. The proposed EGL4 project will have a transmission capacity of 2 GW and will span approximately 646 km, linking Fife in Scotland to West Norfolk in England via a combination of subsea and underground cables. Planning applications are scheduled to be submitted in Scotland in late 2025 and in England in 2026. Subject to approval, construction is anticipated to begin in 2029, with the interconnector expected to become operational by 2033.
In the UK, Prysmian has previously delivered several major interconnector projects, including Eastern Green Link (EGL) 1 and 2 (each with 2 GW capacity), as well as the 1.4 GW Viking Link.
