Contracts awarded to build the UK’s first high-capacity East Coast subsea cable

Construction of the Eastern Green Link 1 (EGL1) by a joint venture between National Grid Electricity Transmission and SP Transmission will see the creation of the UK’s first high-capacity subsea transmission cable from Scotland to England.
EGL1 has awarded the Prysmian Group a £750mn contract to deliver the 525 kV 2 GW HVDC electricity transmission cable from Torness in East Lothian, Scotland, to Hawthorn Pit in County Durham, England. GE Vernova’s Grid Solutions business and MYTILINEOS Energy & Metals have also been awarded a £1bn contract to supply and construct two HVDC converter stations, one at each end of the link.
This upgrade, which will help move clean energy from where it is generated to where it is needed, includes six subsea links between Scotland and England of which this joint project is the first. It will enable the transmission of green energy to power more than two million homes across the UK, says National Grid.
GE Vernova, the consortium leader, and MYTILINEOS will provide the engineering works and technology for the two HVDC converter stations, which form the terminals for the HVDC cable and convert the direct current to alternating current enabling the transmission of electricity into the onshore transmission network. The HVDC cable system is expected to be approximately 190km in length.
Peter Roper, EGL1’s Project Director, says: ‘EGL1 is a transformative project for the UK, enhancing security of supply and helping to connect and transport green power for all customers. These contract announcements are big wins for the supply chain and another important milestone as we build the new network infrastructure to help the UK meet its net zero and energy security ambitions.’
The design phase will begin in January 2024, with construction set to begin in 2025.
