NorNed
Encyclopedia
NorNed is a 580 kilometres (360.4 mi) long HVDC submarine power cable
between Feda
in Norway
and the seaport of Eemshaven
in the Netherlands
, which interconnects both countries' electricity grids. It is the longest submarine power cable in the world. Budgeted at €550 million, and completed at a cost of €600m, the NorNed cable is a bipolar HVDC link with a voltage of ±450 kV and a capacity of 700 MW. NorNed is a joint project of the Norwegian transmission system operator
Statnett
and its Dutch counterpart TenneT
.
Installation of the first sections was started in early 2006; the final section was laid by the end of 2007. On the Dutch shore, TenneT has connected the cable to the 380 kV Dutch high‑voltage grid. In Feda, Statnett has done the same for the 300 kV Norwegian transmission grid. Commercial operation started on 5 May 2008 with a capacity auction. The first commercial power transfer took place on 6 May 2008.
After two months of operation, the cable generated revenues of approximately € 50 million, meaning that in two months’ time, 8% of the total costs of the cable have been recovered. In the business case drawn up for the NorNed cable, annual revenues were estimated at €64 million.
NorNed has been included in European Market Coupling Company
operations as of 12 January 2011.

Submarine power cable
Submarine power cables are major transmission cables for carrying electric power below the surface of the water. These are called "submarine" because they usually carry electric power beneath salt water but it is also possible to use submarine power cables beneath fresh water...
