Contract Details
Description
Prysmian was awarded the main high-voltage direct current (HVDC) cable supply contract for Eastern Green Link 4 by the joint venture of SP Energy Networks and National Grid Electricity Transmission. The construction-phase contract, valued at about £2 billion, covers the design and manufacture of more than 640 km of route-length cable for the 2 GW HVDC link between Fife in Scotland and Norfolk in England. Scope includes approximately 530 km of subsea HVDC cable across the North Sea and over 116 km of underground onshore cable connecting landfalls to the converter stations. The link will reinforce Britain’s east coast transmission corridor, enabling large volumes of renewable power to move from Scotland to demand centres in England and supporting national decarbonisation and energy security objectives ahead of planned operation around 2033.
