Contract Details
Description
ElecLink Ltd awarded Prysmian Group, working in consortium with Balfour Beatty, a major role on the ElecLink France–Great Britain interconnector. Prysmian is responsible for the design, manufacture, supply, jointing, installation and commissioning of the ±320 kV HVDC cable system running through the Channel Tunnel, as well as underground HVAC cables on the UK side. The scope includes approximately 138 km of 320 kV HVDC interconnector cable (two parallel cables along a roughly 69 km route between Folkestone/Cheriton and Peuplingues/Coquelles) and around 14.5 km of underground AC export cables linking the Folkestone converter station to National Grid’s Sellindge 400 kV substation. Prysmian also provided its PRY-CAM online monitoring system for condition diagnosis of the tunnel-installed cables. The contract, part of an overall package valued at about €219 million, represents roughly €83 million for Prysmian and was announced in early 2017.
