  • More facts

    • Originally named the South Saskatchewan River Generating Station.
    • Renamed and officially commissioned in 1959 by Her Majesty Queen Elizabeth II.
    • Three original units with a combined generating capacity of 218 MW.
    • Of the original three units, two units had a combined generating capacity of 123 MW.
    • The third original unit had a generating capacity of 95 MW and was commissioned in 1971.
    • Six 25-MW combustion gas turbines, along with systems to produce additional electricity from waste heat, were commissioned in June 2002. The combined-cycle technology adds 150 MW of supply and reduces our greenhouse gas emissions by an amount equal to emissions from 30,000 cars.
    • Three natural gas turbines were added in 2010. Each one provides 36 MW for a total of 108 MW.

Natural Gas Stations

In a natural gas power station, simple cycle gas 138 turbines inject compressed air into a combustion chamber, along with fuel, to produce a high pressure hot gas stream that is expanded in a turbine to produce electricity. The expanded gas products are exhausted directly to the atmosphere.

    Simple cycle gas turbines, also referred to as open-cycle gas turbines, have the ability to be turned on and off within minutes. For this reason, these turbines are typically used to supply power during peak loads, such as mornings and suppertime.

    Most of the energy potential of fuel is wasted with simple cycle gas turbines when hot exhaust gases are released into the atmosphere.

    In combined cycle facilities, the exhaust gases from each gas turbine are captured and redirected into a waste-heat recovery boiler to produce steam. This steam is used to power a steam turbine, which generates additional electricity.
