North Sea Link, Subsea electrical interconnector between Kvilldal and Blyth, Norway and United Kingdom
The North Sea Link is a subsea high-voltage cable that runs beneath the North Sea to connect the electrical grids of Norway and England. The cable stretches for hundreds of kilometers and passes through deep ocean waters to carry electricity between the two countries.
The project was planned in the early 2000s and construction began in 2015 following extensive studies and approval processes. Once completed, the connection allowed direct power exchange between Norway's hydropower resources and England's energy demand.
The North Sea Link Education Centre introduces students to renewable energy concepts through exhibits about the interconnector system and sustainability practices.
The system operates through converters at both ends that transform alternating current into direct current and back. Visitors cannot access the cable itself, but the engineering work is visible from the surrounding infrastructure and facilities.
A tunnel 2.3 kilometers long was drilled through a mountain to provide the cable a safe route and protect marine habitats. This underground solution shows how engineers solve problems when large projects face natural obstacles.
