Netherlands, Denmark Inaugurate COBRAcable Interconnector
An official inauguration event for the 700MW COBRAcable subsea interconnector is being held today, 4 November, in both Eemshaven (the Netherlands) and Endrup (Denmark), in the presence of representatives from the Dutch and Danish ministries.
According to Prysmian, the cable supplier for the project, the inauguration follows the successful completion of the HVDC test on the interconnector.
Prysmian supplied and installed a ±320 kV HVDC bipole system, using single-core cables with extruded insulation technology and running for a total route of around 325 km, from Eemshaven to Endrup via the German North Sea sector. The project includes two onshore lengths of 1km on the Dutch side and 25km on the Danish side that connect the two onshore converter stations, provided under a separate contract by Siemens.
The 325km subsea high-voltage direct current cable is an initiative of TenneT and the Danish electricity and gas grid operator Energinet.
Construction of the COBRAcable started in 2016 and was completed earlier this year.
The COBRA cable will enable the Netherlands to import more renewable energy, mainly wind energy, from Denmark. The cable connection has been designed in such a way that it will also be possible to connect an offshore wind farm at a later stage.
