Mauricie, QC
Built in 1910 on the Rivière Saint-Maurice falls, I’m Hydro-Québec’s oldest operating generating station. For a long time, I was the most powerful hydropower generating station in North America. Given my advanced age, that title was taken from me decades ago, but I still impress with my beauty and original equipment. For example, I work with eight generating units, some of which still have a horizontal axis!
The tour of the historical complex begins with an exploration of the inside of the Northern Aluminum Company (N.A.C.) power plant, which is located next to me. Commissioned in 1901, it now welcomes the public in a vast exhibition hall. It houses a collection of fascinating heritage industrial machines, including the original turbines used during the construction of La Loutre dam.
The Cité de l’énergie
The N.A.C. and I are part of the historic sector of the Cité de l’énergie
.
Hydro‑Québec is a founding partner, of the Cité de l’énergie, a one‑of‑a‑kind museum complex. It houses a multitude of exhibitions and presents activities that touch on history and science. Here, you’ll get to relive the industrial history of Shawinigan and its region.
Be sure to take the elevator to the top of the lookout tower, an old 115‑metre tower that’s as tall as a 38‑story building. The view is breathtaking!

Built in two phases, I’m a monument to the technological advances of the time. I work with eight generating units, five of which have a horizontal axis and three, a vertical one. The workers here must be versatile. They need knowledge dating back to the beginning of the last century!
I can say without pretense that I’m one of Canada’s top 25 engineering achievements of the 20th century.
The name “Shawinigan” is of Indigenous origin. The Atikamekw nation used the Rivière Saint‑Maurice to travel by canoe for hundreds of years. In Atikamekw, shawinigan means “portage on the crest.”
In the old N.A.C. penstocks, the water flow rate was 30,000 litres per second, equivalent to the contents of an 18-foot pool or 85,000 cans of pop.
The Saint‑Maurice’s watershed covers over more than 40,000 km2. That’s the equivalent of the area of Switzerland! A watershed is a geographical area bounded by ridges that carry rainwater to one place.
Some images are from the Hydro‑Québec Archives.
You may know that I was once considered the flagship of the Shawinigan Water and Power Company’s hydropower fleet. Today, I can boast that I’m the oldest hydropower generating station in Québec still in operation. Here are some milestones in my history.

At the end of the 19th century, Bostonians John Edward Aldred and John Joyce bought the Shawinigan waterfalls on the Rivière Saint‑Maurice from the Québec government for $50,000, the equivalent of approximately $2,000,000 in today’s dollars. In 1897, the two Americans founded what would become one of the greatest industrial empires of the time, the Shawinigan Water and Power Company (the “SW&P”).

Don’t take our word for it: this is what the people who visited the generating station with our guides had to say.
A must-see to understand Québec and its great capacity for innovation, as well as its regions and their place in history.
It’s the only place where we can see generating units with a horizontal axis.
It was really well organized. Interesting experiences for everyone, children and adults alike!
