Challenges
- Nova Scotia wants to import power generated from the Muskrat Falls generating station in Labrador.
- A major interconnection of transmission systems is between the island province of Newfoundland and the mainland province of Nova Scotia in Canada.
- The new 500 MW, +/- 200 kV HVDC link will need to run via submarine cable across the 170 km Cabot Strait.
Solutions
- 孵化is providing all engineering and design services for the terrestrial components of the project.
- We’re also designing telecommunication and accommodation facilities, access roads, and site preparation works for AC/DC converter stations and AC substations.
Highlights
- Design headquarters established in Halifax to ensure smooth collaboration with the NSPML team there.
- The 350 km of new overhead transmission lines will have a relatively low environmental footprint because they are being built mostly along the right-of-way of existing transmission lines.
- 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.
