Building the Muskrat Falls Generating Facility – 2014-2017

Thousands of Newfoundlanders and Labradorians help build Atlantic Canada’s second largest hydro plant

Thanks to the hard work and dedication of more than 4,600 skilled workers from our province, we’re proud to announce that Astaldi has substantially completed construction of the powerhouse and intake structures for the Muskrat Falls generating facility. Construction of these structures moves us closer to delivering first power from the generating plant in 2019. Once in operation, the Muskrat Falls generating facility will be the second largest hydro plant in Atlantic Canada – the Churchill Falls generating facility is the largest.

In January 2014, Astaldi started construction on the spillway, powerhouse and intake structures for the Muskrat Falls generation project. Since then over 330,000 m3 of concrete has been placed to build these three main structures and about 3,800 metric tonnes of structural steel has been installed for the intake and powerhouse.

“I congratulate everyone who played an important part in safely achieving this tremendous milestone on the project,” says Scott O’Brien, Project Manager – Muskrat Falls Generation. “With construction on these critical components completed, we are now installing the four generating units in the powerhouse. We are focused on delivering power to the people of the province from the Muskrat Falls generating plant in 2019.”

“We’re proud to be part of this mega energy project in Newfoundland and Labrador and proud of the work done by the entire Astaldi team,” said Don Delarosbil, Project Manager Astaldi. “We are making very good progress on execution. We have reached many milestones since first concrete was placed in 2014. It’s thanks to the hard work and dedication of every worker that the spillway structure was completed last year and now this year, we have substantially completed the powerhouse and intake structures.”

More than 88 per cent of Astaldi’s team was skilled comprised of Newfoundlanders and Labradorians. While hiring local workers for the project, Astaldi also focused on diversity – employing 600 Aboriginal workers for their projects.

“I would like to extend a sincere congratulations on this significant accomplishment on the Muskrat Falls project,” says Darin King, Executive Director, Trades NL. “Thanks to the contractors and the project leadership team for supporting all of our members – professional craft labour – as we’ve worked together to achieve this milestone.”

With the powerhouse building now constructed and enclosed, work continues on the assembly and installation of the four massive generating units in the powerhouse.

Quick Facts:

  • The spillway is made up of five bays with gates that open and close as needed to control the release of water from the reservoir (area upstream of the facility).
  • The intake draws the water from the river into the powerhouse and then onto the turbines and generators where electricity will be generated. Installing the intake gates is the first step in the process of moving water through the powerhouse where electricity will be made.
  • The powerhouse houses the four generating units, which are the mechanical and electrical components required to generate the electricity.
