Endrup, Denmark: Submarine Cable Landing Point

Endrup is a locality in western Denmark, situated near Esbjerg on the country's North Sea coast. One submarine cable lands at Endrup, connecting Denmark directly to the Netherlands across the North Sea. This cable link represents a cross-border corridor between two neighbouring North Sea nations, spanning a relatively short but strategically placed stretch of seabed.

The single cable landing at Endrup is COBRAcable, a high-voltage direct current submarine power cable linking Endrup to Eemshaven in the Netherlands. Rather than carrying telecommunications data, COBRAcable is an HVDC electricity interconnector, making Endrup a notable point in the European power grid's submarine infrastructure. The cable is jointly owned by Energinet.dk and TenneT, and it entered service in 2019.

Cables Landing at Endrup

COBRAcable entered service in 2019 and runs 304 kilometres between Endrup, Denmark and Eemshaven, the Netherlands. The cable is an HVDC submarine power interconnector rated at ±320 kV and 700 MW, with the latter corresponding to an annual transmission capacity of 6.1 TWh. It is jointly owned by Energinet.dk and TenneT and is designed to improve the European transmission grid and increase the integration of variable wind power generation across the two countries, while also improving supply reliability. COBRAcable is the sole submarine cable presently landing at Endrup.

Regional Context

Denmark hosts 30 submarine cables across 34 landing points, and Endrup, with its single cable, sits in the lower portion of that national distribution, ranking within the top 74 percent of Danish landing points by cable count. Among its regional peers, Blaabjerg leads with five cables, followed by Gedser with four, while Brondby, Helsingør, Houstrup, and Laeso each host two. Endrup's profile is therefore modest in scale compared with Denmark's busier landing points, though its role as an HVDC power interconnector terminal gives it a distinct character within the national submarine cable landscape.

Network Role

Endrup functions as a single-cable terminus rather than a multi-cable hub, with COBRAcable providing a direct submarine power link between the Danish and Dutch electricity grids. The corridor it enables — across the North Sea between western Denmark and the northern Netherlands — supports the movement of up to 700 MW of electrical capacity in either direction, facilitating the cross-border exchange of power generated from variable renewable sources, particularly wind. The cable's relatively compact length of 304 kilometres, below Denmark's national average of 452 kilometres for submarine cable length, reflects the geographic proximity of the two countries across the southern North Sea.

Within the broader submarine cable graph of the North Sea region, Endrup's role as the Danish terminus of COBRAcable positions it as part of the growing network of subsea power interconnectors linking European national grids, complementing the telecommunications-focused cables that dominate many of Denmark's other landing points.
