Mountain Chute Generating Station (GS), which is located in Greater Madawaska Township in Renfrew County, produces 170 megawatts (MW) of clean, renewable electricity. This is enough electricity to power about 170,000 homes.
 
Mountain Chute is upstream from four other hydroelectric facilities on the Madawaska River: Barrett Chute GS, Calabogie GS, Stewartville GS and Arnprior GS. Together, these five stations have the capacity to power 615,000 homes.
 
Developed in the mid 1960s, this large scale project brought an economic boom to the area, employing 500 people at the peak of construction. About 8,500 acres of land was flooded to create a reservoir, allowing water to be held back and used at times of the day when electricity demand is higher. The reservoir, called Centennial and Black Donald Lakes, covers the abandoned Black Donald Mining settlement and graphite mine which was closed in 1947.
 
As with the operations at all of our generating stations, OPG is considerate of the environment and other users of the waterways. Our technicians manage water levels and flows according to the approved Madawaska River Water Management Plan. The amount of water available for generation depends on environmental needs, minimum and maximum water level requirements, and precipitation.
 
Mountain Chute GS is part of OPG’s clean energy portfolio which is more than 99 per cent free of greenhouse gas and smog emissions.
