NKT announced that it has won a contract from Energinet and National Grid to supply power cable for the Viking Link interconnector project that will connect Danish and British transmission grids.
A press release said that the order from the owners of Viking Link, worth approximately €90 million, will see NKT provide approximately 150 km of 525 kV MI high-voltage DC onshore power cables. The NKT power cables will be manufactured in Karlskrona, Sweden, with production expected to start in 2020. The power cable will run from the Denmark shore to the power grid substation in Revsing, southern Jutland.
NKT Interim CEO Roland Andersen said that the Viking Link is a key project for the North-European transformation towards renewable energy supplies. "The award is a recognition of our technological competences also in the growing extra high-voltage interconnector segment from Energinet and National Grid."
The release said that when completed, the760-km long DC interconnector line will help balance wind production and demand across countries, and closer integration between transmission grids is important for the efficient transition towards a green energy future. Implementation of Viking Link is a vital step towards achieving ambitious renewable targets in both Denmark and the U.K. The interconnector line is scheduled for commissioning in 2023.
The Prysmian Group, a world leader in the energy and telecom cable systems industry, has been awarded a contract from National Grid Viking Link Limited and Energinet to supply the majority of the power cable that will be needed for Viking Link, the first submarine cable connection between the U.K. and Denmark.
A press release said that the contract for Prysmian, worth close to €700 million, includes the turn-key design, manufacture and installation of the world’s longest interconnector. The project will require 1,250 km cable for the submarine route, and some 135 km of the land cables for the U.K. side. A separate related award for land cables was issued to NKT.
The High Voltage Direct Current (HVDC) interconnector will operate at ± 525 kV DC. It will allow up to 1,400 MW of power to be transferred between the two countries, passing through U.K., 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, U.K., to the converter station located at Revsing in southern Jutland, Denmark.
"This project further confirms our undisputed market and technology leadership," said Hakan Ozmen, EVP Projects, Prysmian Group.
Prysmian plans to manufacture all cables for the project at its operations in Arco Felice, Italy, with the offshore cable operations to be carried out by its new installation vessel. Jointly owned by Energinet and National Grid, the Viking Link interconnector project is scheduled to be commissioned at the end of 2023.
"We are proud to have the opportunity to support two of our most important customers, National Grid and Energinet, in the development of such a strategic infrastructure, which will represent a milestone for the upgrade of the entire EU power transmission grid," said Prysmian Group CEO Valerio Battista.
