About this project

The Maritime Link Project is part of a larger strategy to address the growing demand for more renewable energy. It will enable the transmission of clean, renewable and reliable electricity from Newfoundland and Labrador to Nova Scotia and beyond. The Maritime Link will allow Nova Scotia to import hydro electricity from the Muskrat Falls generating station in Labrador, which is being developed by Nalcor Energy as part of the Lower Churchill Project.

Project infrastructure

The Project involves building 170 kilometres of subsea HVdc (high-voltage direct current) transmission cables under the Cabot Strait, overhead transmission in Newfoundland and Labrador and Nova Scotia and the following elements and associated infrastructure:


For Newfoundland and Labrador, the Maritime Link will connect the island of Newfoundland to the North American grid for the first time in history. This alternative electrical-transmission route will make the abundance of energy in Newfoundland and Labrador available for export to Nova Scotia and beyond.
