National Grid And SSEN Transmission Agree Joint Venture For UK’s Largest Ever Electricity Transmission Project

The title of this post is the same as that of this press release from National Grid.

This is the sub-heading.

Joint Venture Agreement Important Milestone In Subsea Electricity Superhighway – Eastern Green Link 2

These four paragraphs outline the project.

National Grid Electricity Transmission (NGET) and SSEN Transmission have taken a big step forward in the development of a new subsea electricity superhighway project along the east coast of Scotland after reaching agreement on the terms of their joint venture (JV).

The ‘Eastern Green Link 2’ (EGL2) project will see the creation of a 525kW, 2GW high-voltage direct current (HVDC) subsea transmission cable from Peterhead in Scotland to Drax in England. The UK’s single largest electricity transmission project ever.

The subsea HVDC cable system is approximately 436km in length with new converter stations at either end to connect it into the existing transmission network infrastructure. HVDC technology provides the most efficient and reliable means of transmitting large amounts of power over long distances subsea.

The EGL2 link will support the growth of new renewable electricity generation, creating jobs and delivering a pathway to net zero emissions targets, as well as helping to alleviate existing constraints on the electricity network.

The Wikipedia entry for Eastern HVDC has a detailed description of the two 2GW Scotland-England interconnectors, that are planned.

This is the first section.

Eastern HVDC and Eastern HVDC projects are the names used by Ofgem for two planned HVDC submarine power cables from the East coast of Scotland to Northeast England to strengthen the National Grid. The two links combined will deliver 4 GW of renewable energy from Scottish wind farms to England.

Ofgem state that “At an estimated cost of £3.4 billion for the two links, the Eastern HVDC projects would be the largest electricity transmission investment project in the recent history of Great Britain.

The Project Background Document for SEGL1 can be viewed here.

EGL2 also has its own web site.

  1. Its laughable that they are celebrating this this is critical national infrastructure if govt is serious net zero. The ESO coordinates across all the transmission operators and came up with this scheme as essential for net zero so just get on and build it not keep talking about it.

  2. Iberdrola, who own ScottishPower, have just announced a £12bn investment programme, which will include getting underway on EGL1. Work will start early next year, with completion slated for 2029. https://www.iberdrola.com/press-room/news/detail/iberdrola-sets-out-12bn-investment-plan-at-uk-global-investment-summit
