Siemens wins converter station jobs on £2.5bn EGL4 subsea link
Siemens Energy has been named preferred bidder to build two HVDC converter stations on the £2.5bn Eastern Green Link 4 subsea electricity scheme connecting Scotland and England.
The contract award marks a key milestone for National Grid and SP Energy Networks, who have signed a joint venture to deliver the 2GW link, which will run 530km from Fife to West Norfolk.
EGL4 is the third in a series of planned subsea “electricity superhighways” designed to boost energy security by transporting clean wind power from Scotland to demand centres in England.
Project brief
- A 530km subsea High Voltage Direct Current (HVDC) cable between Kinghorn, Fife, and Anderby Creek, Lincolnshire
- A 16.4km underground cable from Kinghorn to a new converter station at Westfield, near Ballingry, Fife
- A 100km underground cable from Anderby Creek to a new converter station near Walpole, Norfolk

The Siemens converter station package follows a competitive tendering process and comes ahead of full contract award later this year.
Planning applications for the Scottish and English sections of the scheme are due in late 2025 and 2026 respectively, with construction expected to start in 2029 and the link operational by 2033.
James Goode, project director at National Grid, said: “Reaching preferred bidder stage is a key milestone for EGL4 and a sign of the progress being made on this vital infrastructure project.”
The converter contract follows Siemens Energy’s appointment to National Grid’s £59bn HVDC supply chain framework and SPEN’s £5.4bn strategic supplier panel.
