Contracts for World’s biggest interconnector awarded

Contracts worth €1.5 billion have been awarded to build an electricity link between England and Norway. When it is complete, the interconnector will be the longest in the world; NSN Link Limited gave the contracts to Nexans and Prysmian, who will be responsible for constructing the 740 km route.

The England and Norway link will be the first time that two countries have shared a direct energy system; the project is a collaboration between the National Grid and Norwegian company Statnett SF.

The cables will run from Blyth in Northumberland to Kvilldal in Norway. It will require almost 1500 km of cable to complete the project and there will also be a 10 km offshore route.

Prysmian will be providing 950 km of the submarine and land cables; they will also be responsible for installing them. Prysmian will manufacture the cables in a factory in Naples and they will use a specially designed cable laying vessel, which is called the “Giulio Verne”.

Nexans will be providing cabling for the Norwegian side of the connection; they will manufacture the cables in their Halden-based factory.

Commenting on the project, Alan Foster, National Grid’s director of European Business Development, said

“There is a huge programme of work for us to undertake over the next five years to deliver what will be the world’s longest interconnector.  Our contractors will have a big part to play in that successful delivery. But the benefits to both UK and Norway are also huge and when completed the link will deliver low carbon electricity for the UK and also add to security of supply for Norwegian consumers.”

Håkon Borgen, Executive Vice President of Statnett, added that the project was vital for the future of the energy system in Europe.

The licence that will allow the project to go ahead was first granted in 2013 when the Norwegian Ministry of Petroleum and Energy gave permission for the interconnector to be built. Preparation work at the site will begin in 2016 and will continue into 2017 when construction will get underway

The link between the two countries will have numerous benefits including helping to provide a more secure power supply for both the UK and Norway, and the construction work will help to provide jobs. When the link has been finished it will have the capacity to produce 1400 MW of power.

It is expected that the work would be completed in 2019 and the interconnector will be operational by 2020.
