The hydroelectric facility at Muskrat Falls on Labrador’s Lower Churchill River is moving from concept to concrete reality.

Nalcor Energy has issued a news release marking the start of concrete pouring for the spillway structure at the Muskrat Falls site. The facility will require concrete for the spillway, powerhouse and dam structures.

According to Nalcor, 560,000 cubic metres of concrete will be needed for the powerhouse and spillway structures — enough for three Hebron gravity‐based structures (GBS).

The Hebron GBS is currently under construction at Nalcor’s Bull Arm fabrication facility.

At Muskrat Falls, another 200,000 cubic metres will be needed to build the dams. According to Nalcor, the two will collectively be longer than seven CFL football fields, with one 32 metres high and another 20 metres.

The concrete work for Muskrat Falls started today.

“We have reached yet another significant milestone for construction of the Muskrat Falls project,” said Gilbert Bennett, a vice-president at Nalcor Energy and lead on the power project.

“This milestone was achieved through the commitment of the entire team working together on this historic project. Their dedication to safety, productivity and teamwork is evident on this project every day.”

Construction of the Muskrat Falls dam and Labrador-Island Link — for the transmission of power from the Lower Churchill River to the Avalon Peninsula — began in 2012.

As of the latest available figures, from June, employment on the project approached 3,000 people.
