  • More facts

    • Located on the Churchill River near the Manitoba-Saskatchewan border.
    • Seven units in total with a combined generating capacity of 111 megawatts (MW).
    • The first three units were installed when the plant was constructed in 1929-1930. Hudson Bay Mining and Smelting Company (HBM&S) installed a fourth unit in 1936. Two more units were installed in 1938 and 1947, with the final one being installed in 1959.
    • The Station was built by the Churchill River Power Company Limited, a subsidiary of HBM&S, to supply power for mining operations at Flin Flon.
    • SaskPower took ownership of the station in 1981 and assumed operations in 1985.

Hydroelectric Stations

Hydroelectricity is created by falling water. 138 Water from reservoirs flows through the penstocks that connect the reservoir to the station. The water turns a hydraulic turbine, which rotates a generator and produces electricity

    Once the water has been through the turbine, it is directed into the exit, called a tailrace. The water is then returned to the river below the dam where it continues downstream toward its natural destination.

    By holding water in the reservoir, the potential for immediate electricity is stored. Excess water from heavy rains or spring run-off can be released from the reservoir through spillway gates, if required.
