SSEN Transmission has launched the tendering process for civil works related to the northern converter station on the proposed Eastern Green Link 3 (EGL3), a 2GW high-voltage direct current (HVDC) subsea connection being developed in partnership with National Grid Electricity Transmission.
The project, which will operate at 525kV, is planned to run approximately 680 kilometres between Peterhead in Aberdeenshire and the Norfolk coast in eastern England. The newly tendered package covers infrastructure at the Netherton Hub converter station, including HVDC buildings, access roads, drainage systems, and fencing.
SSEN Transmission confirmed that this tender represents the final package for the northern section of EGL3, which is targeted for completion by 2033.
“This tender marks another important step in securing the supply chain for our Pathway to 2030 programme,” the company said, referring to the wider £22 billion investment plan aimed at strengthening the UK electricity grid and supporting the integration of renewable energy from Scotland.
EGL3 is part of a series of subsea transmission links designed to deliver low-carbon electricity from the north of Scotland to demand centres across the UK. The project is considered critical to meeting national net-zero targets and ensuring long-term energy security.
The tender process adds momentum to the broader effort to expand the UK’s transmission capacity as more offshore wind and renewable generation comes online over the coming decade.
