National Grid is celebrating five years of successful operation of its IFA2 interconnector — the 1GW high voltage direct current (HVDC) electricity link which is enabling secure and cleaner electricity to flow between Great Britain and France. IFA2 demonstrates in practice how cross border links strengthen resilience and energy security in both countries.

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.

Once completed in 2033, it will be capable of transporting enough green electricity to power more than 1.5 million homes.
