Hydro-Canyon Saint-Joachim

The power plant is embedded within a natural canyon and enough water remains in the Sainte-Anne waterfall to preserve the site’s integrity.

Preserving the natural beauty of the site and of the installation located halfway between two geological formations in a highly seismic area was a determining factor in the selection of the location and design of the infrastructure assets. Retained by a nine-metre high dam, water circulates through a 440 m tunnel excavated in the bedrock. The water intake is hidden from hikers’ view by a bend in the river and the dam gives the impression of being a natural cascade.

This hydroelectric development was recognized with a Quebec Consulting Engineering award in the “Energy” category in 2018.
