HVDC converter supplier chosen for UK’s Eastern Green Link 1

A consortium of GE Vernova’s grid solutions business and Mytilineos has been chosen as the preferred supplier for two high-voltage direct-current (HVDC) converter stations for the Eastern Green Link 1 (EGL1) project in the UK. 

The project – a joint development by SP Transmission and National Grid Electricity Transmission – will see the creation of a 525kV, 2GW HVDC subsea transmission cable from Torness in East Lothian, Scotland to Hawthorn Pit in County Durham, England. 

When complete, EGL1 will enable the transmission of electricity from wind farms and other renewable energy assets to power more than two million homes across the UK.

GE Vernova and Mytilineos will provide the engineering works and technology for the HVDC convertor stations, which form the terminals for the HVDC cable and convert the direct current to the alternating current used in the onshore transmission network. 

Prysmian Group was recently announced as the exclusive preferred bidder for the HVDC cabling contract. 

Following final approval from energy regulator Ofgem, full contracts are expected to be completed later this year, with construction work due to begin in 2024. The project’s targeted commercial operations date is 2029.
