Prysmian and NKT will supply the cables for the Viking Link interconnector project that will balance Danish and UK renewables supply.
Prysmian’s €700m contract is for the turnkey design, manufacture and installation of the world’s longest interconnector with the entire 1250km cable for the submarine route and all of the 135km of land cables on the UK side, for the four out of five lots awarded.
NKT’s €90m contract is for supplying the onshore power cables for the supply of 150km of 525kV high-voltage direct current onshore power cables connecting the Danish and British transmission grids.
When completed, the Energinet and National Grid owned Viking Link will run between Revsing in southern Jutland, Denmark and Bicker Fen in Lincolnshire, UK, balancing wind production and demand across the countries.
The HVDC interconnector will allow up to 1400MW of power to be transferred between the two countries passing through UK, Dutch, German and Danish waters, using single-core, mass-impregnated paper-insulated cables.
The system will connect the converter station located at Bicker Fen in Lincolnshire to the converter station located at Revsing in southern Jutland.
It will increase access to renewable and sustainable energy sources to more than 1.4 million households, reducing the cost of electricity in the UK and providing additional system reliability.
Prysmian will make the cables for the project at its factory in Arco Felice, Italy.
The offshore cable operations will be performed using Prysmian’s new vessel.
The interconnector is expected to be fully commissioned in 2023.
The NKT power cables will be manufactured in Karlskrona, Sweden, with their production expected to start in 2020.
