Major construction activities include:
- Surveying and constructing infrastructure (access roads, bridges, marshalling yards and temporary construction camps).
- Site clearing and earthworks for the converter station, switchyard and synchronous condensers as Soldiers Pond.
- Clearing and preparation for the transmission line right-of-way.
- Installation of tower foundations.
- Assembly and installation of transmission towers.
- Installation of conductor and grounding system.
- Building a converter station at Muskrat Falls and Soldiers Pond, as well as grounding stations at L’Anse au Diable and Dowden’s Point.
- Building the Strait of Belle Isle cable transition compounds on each side of the Straits, which act as the transition point between the subsea cable and overhead line.
- Inspection and commissioning of the line.
Construction began in summer 2014 with clearing activities for the 60 m wide transmission line right-of-way in Labrador. Clearing on the island of Newfoundland began in winter 2015. Construction activities will be carried out in sequence from Muskrat Falls to the Avalon Peninsula. In the majority of regions, construction will take place away from residential areas.
Once operational, the Labrador-Island Link will be similar to existing transmission lines across the province. Activities associated with operations and maintenance will be integrated into Newfoundland and Labrador Hydro’s (Hydro) existing transmission system inspection and maintenance program. Maintenance activities will include regular inspection, repairs and vegetation management along the right-of-way as required.
