Astaldi Canada will construct the Muskrat Falls Hydroelectric Generation Facility on the lower Churchill River in Labrador. This project includes the construction of the intake and powerhouse, spillway and transition dams, with a generating station of 824MW capacity.
In December 2013, Astaldi Canada was awarded the contract to carry out the civil works for the Muskrat Falls hydroelectric project in Labrador, making us the largest employer on the project. Our work will involve the construction of an intake, powerhouse, gated spillway and transition dams, with a generating station of 824MW capacity.
The construction of the Muskrat Falls Project is taking place just 30 kilometers west of Happy Valley–Goose Bay, Labrador. The project includes a collaborative relationship with and commitment to the Labrador Innu Nation and residents of Newfoundland and Labrador. Currently, our workforce is made up of more than 90 per cent residents of Newfoundland and Labrador. Other benefits our work will bring to the province include:
- Employment opportunities for the Labrador Innu Nation and residents of Newfoundland and Labrador;
- Hundreds of millions of dollars in procurement opportunities for businesses and services in Newfoundland and Labrador; and,
- Direct economic benefits to communities near the Muskrat Falls hydroelectric project.
At the conclusion of project, Muskrat Falls will be the second-largest hydroelectric facility in Atlantic Canada and will produce a clean, renewable source of electricity to better meet Newfoundland and Labrador’s growing energy demands.
Astaldi Canada’s contract includes the construction of the intake and powerhouse, spillway and transition dams including:
- Construction of the powerhouse and the intake which includes concreting, steel structure, embedment parts and miscellaneous metals as well as the architectural works related to the envelope of the powerhouse building;
