Intertek Backs UK-Norway Interconnector

Grid Connection

Intertek has helped to support National Grid and Statnett in the development of an infrastructure project linking the UK and Norwegian electricity networks (NSN Link) which, when constructed, will be the world’s longest high voltage direct current (HVDC) undersea interconnector.

For the past four years, Intertek has acted as marine consultants for the two companies in the NSN project that culminated in successful UK marine consent for the venture in late 2014.

National Grid and Statnett recently announced their final investment decision for developing the NSN, a 730-kilometre 1,400 MW power cable link between UK and Norway. The interconnector is planned to be completed by 2021. Once operational, it will supply nearly 750,000 homes in the UK with low-carbon electricity.

Intertek’s specialist technical services and marine planning advice for the NSN project included cable routing constraints and feasibility studies, route engineering, survey management, environmental assessment and stakeholder engagement.
