Landsvirkjun examines sub-sea cable to supply renewable energy to Europe

Landsvirkjun, the Icelandic energy provider, has been examining how realistic it would be to build the world’s longest submarine electric cable, which will enable sales of renewable energy to Europe.

The energy company’s study concentrates on the potential business models, markets and congestion management, whilst also focusing on the export and import of electricity based on price differences between the European and Icelandic market. Landsvirkjun is also studying the impact on the Icelandic power market, security of supply in the Icelandic power system and resource management in Iceland, with emphasis on the use of the hydropower capacity.

The destination countries being discussed are Norway, Germany, the Netherlands and the United Kingdom. The shortest possible distance of a cable from Iceland to a landing site in Europe is about 1.200 km, more than double the length of the NorNed (Norway-Netherlands) interconnector, and a sub-sea cable to the continent would be around 1.900 km. The transmission capacity examined is between 600 and 1.000 MW.

It is estimated that it will take further four to five years to study the feasibility and technical and economical aspects of building such a marine cable. If and when a decision has been taken, further four to five years are needed for production and installation of the cable, construction of converter stations and other related tasks. The project could thus commence operation around 2020 at the earliest.
