Strait of Belle Isle Marine Cable Crossing

To transmit power generated at Muskrat Falls to the island of Newfoundland, a 35 km underwater cable crossing will be constructed across the Strait of Belle Isle from Forteau Point, Labrador to Shoal Cove, on the island of Newfoundland.


Site clearing and development began in Forteau and Shoal Cove in 2013. Once completed, horizontal directional drilling (HDD) activity was carried out, with drill rigs and other equipment operating on both sides of the Straits to create boreholes for the submarine cables. HDD activities were completed in August 2014.

In 2016, a cable installation vessel will begin installingĀ the three transmission cables on the sea floor. Rock berms will then be placed over each cable by a rock-laying vessel, to protect the cables from marine vessel traffic and fishing activity. Transmission compounds will also be constructed in Forteau and Shoal Cove.
