Delivering green electricity ahead of schedule at Peribonka Generating Station!

Built to provide residents of Quebec with hydroelectric energy, the Peribonka Generating Station was completed in only four years…and three months ahead of schedule! The project - carried out at a depth never before seen anywhere in the world - required sophisticated technologies, including LafargeHolcim's concrete.

 

Located near the Saguenay-Lac-Saint-Jean area in Quebec, the Peribonka Generating Station is an 80-meter dam designed to produce 386 MW of hydroelectric power per year. Completed in 2007, the dam was the first in the world to include a plastic-concrete, 110-meter-deep cutoff wall to ensure water tightness. The massive project also included two main embankments and a 33-kilometer-long reservoir.

Due to the area’s complex environmental and geological conditions, the project required an array of technical specifications. To provide consistent on-site delivery, LafargeHolcim set up a mobile concrete plant, producing 90,000 m3 of concrete over two years. And tackling the project’s complexity and tight deadlines? Our project management expertise really hit the mark, helping to deliver the project ahead of schedule and on budget.

Providing clean, renewable energy to thousands of Quebec residents, the Peribonka Generating Station is truly a marvel of modern engineering!
