National Grid Electricity Transmission and SP Energy Networks have selected Prysmian as preferred bidder to deliver the high-voltage direct current (HVDC) cable system for the Eastern Green Link 4 (EGL4) project.
The proposed 2GW subsea and underground connection will run 646km between Fife in Scotland and West Norfolk in England. Once complete, it will have the capacity to carry renewable energy to power around two million homes, strengthening energy security and advancing the UK’s transition to cleaner, more affordable electricity.
The appointment follows a competitive procurement process and marks a key milestone ahead of full contract award. Planning applications are scheduled to be submitted in Scotland in late 2025 and in England during 2026. The decision does not pre-empt the outcome of those processes.
Subject to approval, construction of EGL4 is expected to begin in 2029, with the link due to become operational in 2033.
