UK: National Grid Electricity Transmission and SP Energy Networks have selected Siemens Energy as the preferred bidder for two high voltage direct current (HVDC) converter stations for the Eastern Green Link 4 (EGL4) project. EGL4 is a proposed 2 GW HVDC link which will transport clean energy between Fife, Scotland and West Norfolk, England and onto the network via a 530 km HV subsea cable. The link is one of five proposed subsea links between Scotland and England being delivered through joint ventures with Scottish transmission owners, which will be able to supply power to 10 million homes.
Siemens Energy was also awarded a place on National Grid’s £59 billion HVDC supply chain framework and SP Energy Networks’ £5.4 billion Strategic Agreement to deliver the required works and equipment necessary for energy projects across the country. The preferred bidder selection follows a competitive procurement process and marks a key step for delivery of the strategically important project, ahead of full contract award.
EGL4 recently concluded its second stage of public consultation at both ends and is utilising this feedback to inform the projects development which includes the planning application in Scotland, expected during late summer 2025 and an application for development consent to the Planning Inspectorate in England during 2026. Construction is expected to begin in 2029, with the link becoming operational in 2033.
