Labrador-Island Transmission Link Project

Projects that were undergoing a comprehensive study at the time the provisions of the Canadian Environmental Assessment Act, 2012 came into force will continue to follow the requirements of the former Act. Under the former Act, the Canadian Environmental Assessment Agency is responsible for conducting the comprehensive study of this project.

This environmental assessment was started as a screening on November 24, 2009. On, April 14, 2010 as a result of the January 21, 2010 Supreme Court of Canada ruling in MiningWatch Canada v. Canada (Minister of Fisheries and Oceans et al.), it was determined that the environmental assessment in relation to this project will be continued as a comprehensive study.

The Labrador - Island Transmission Link Development Proposal, as presented by the proponent, Nalcor Energy, involves the construction and operation of an approximately 1,100 km long transmission line and associated infrastructure within and between Labrador and the Island of Newfoundland.

The scope of the project includes the High Voltage Direct Current (HVDC) overhead transmission line commencing at a converter station at Muskrat Falls in central Labrador, proceeding southeast across Labrador, crossing the Strait of Belle Isle via submarine cables, and proceeding across Newfoundland to end at a converter station at Soldiers Pond on the Island's Avalon Peninsula. The project will include the installation of shoreline electrodes (with associated transmission lines) at two locations, in the Strait of Belle Isle at L’Anse au Diable and in Conception Bay at Dowden's Point.
