- Owned by Meridian Limited Partnership, a wholly owned entity of Stanley Energy Inc.
- The Plant consists of two natural gas generating units and a steam turbine generator.
- This was SaskPower’s first large-scale cogeneration energy purchase.
- The plant also produces steam for Husky’s Lloydminster heavy oil upgrader operations.
Natural Gas Stations
In a natural gas power station, simple cycle gas 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.
