Cable manufacturer Prysmian has been awarded a £2bn contract to supply the cable for National Grid Electricity Transmission and SP Energy Networks subsea Eastern Green Link 4 project.

The contract will see Prysmian manufacture and deliver over 640km of cable for the 2GW subsea electricity link, which will use high voltage direct current (HVDC) to connect Fife in Scotland and Norfolk in England.

The project is a joint venture between National Grid Electricity Transmission and SP Energy Networks. It will increase Britain’s capacity to move power around the country, reducing constraints, increasing energy security and enabling more clean power to connect to the grid.

Project director for National Grid, James Goode said: “Eastern Green Link 4 is a critical part of the significant reinforcement needed along the east coast to support Britain’s future energy system. By investing in high-capacity HVDC infrastructure, we can move large volumes of clean electricity efficiently and at scale.”

The SP Energy Networks and National Grid Transmission joint venture partnership is building two links that will straddle the east coast of the country. Prysmian is also supplying the cable for Eastern Green Link 1, the 2GW project, which started construction last year and will connect Torness in Scotland and Hawthorn Pit in England.
