It was in 2016 that the hydroelectric power station of started up a hydroelectric power station over water 300 meters upstream from Canyon Sainte-Anne. The Hydro-Canyon Saint-Joachim run-of-river power plant project was designed taking into account the technical and environmental aspects of the integration environment. The development will harmonize with the recreotourism facilities of Canyon Sainte-Anne. The works will optimize the site on the hydroelectric level while developing the potential of the Sainte-Anne waterfall. The maximum power of the plant will be 23.2 MW. The installation will include:
A weir threshold to maintain the upstream level of the river
A substation and a power line connecting the site to the Hydro-Québec network
