National Grid and SP Energy Networks have selected a consortium to deliver the next phase of works for a £2.5 billion subsea transmission cable. The Eastern Green Link 1 (EGL1) will be a 525kV, 2GW high voltage direct current (HVDC) link from East Lothian in Scotland to County Durham in England. Once completed, the 190km cable is expected to carry enough power to supply more than 2 million homes across the UK.
