Developers Seek Interest in UK-Norway Interconnector Cabling Work

Under the project called “NSN”, the companies are developing a subsea link between these two countries with a capacity of 1,400 MW. The link will pave the way for further integration of the North-European power markets and strengthen its power grid.

This project will largely contribute to the production and consumption of renewable energy and help achieve EU 2020 renewable goals.

The UK-Norway interconnector is expected to be completed by 2019/2020. When completed, it will be the world’s longest subsea power cable.
