Mar 6, 2020 - COBRAcable Constructing the green cable documentary
Since 2019 the Danish and Dutch high-voltage grid are interconnected via a high-voltage direct current submarine cable, the COBRAcable.
TenneT and Energinet, Danish electricity and gas grid operator, realised a high-voltage direct current submarine cable that interconnects the electricity grids of The Netherlands and Denmark. COBRAcable runs from Eemshaven (the Netherlands) to Endrup (Denmark) via the German sector of the North Sea. Two onshore converter stations, one in the Netherlands and one in Denmark, convert alternating current into direct current. This is necessary to transport the electricity without major losses. The converters also convert direct current back into alternating current; the Dutch and Danish electricity grids operate on the basis of alternating current.
