TenneT, Energinet.dk Award €250M COBRAcable Contract to Prysmian

Prysmian Group has been awarded a contract worth around EUR 250 million by TenneT TSO B.V. and Energinet.dk for COBRAcable, the HVDC submarine interconnector that will link Denmark and the Netherlands.

The contract awarded to Prysmian involves the turn-key supply and installation of an HVDC bipole – using single core cables with extruded insulation technology – that will operate at a voltage level of ±320 kV with a rating of approximately 700 MW, equivalent to the annual electricity consumption of all households in the cities of Rotterdam and Amsterdam combined.

It will run along a total route of around 325 kilometres, from Eemshaven to Endrup via the German sector of the North Sea, and will include two onshore lengths of 1 km on the Dutch side and 25 km on the Danish side to link to the onshore converter stations, which are to be provided under separate contract by Siemens.

The marine cable laying activities, which will be performed by Prysmian’s own cable-laying vessels, the Cable Enterprise and the Giulio Verne, will also see the use of their newly acquired barge.

Delivery of the cable system is scheduled by the 3rd quarter of 2018.
