TransAlta’s Mississauga facility was commissioned in 1992 and has two LM6000 PC gas turbines (the same used in a 747 aircraft, modified to generate electricity). Each is capable of generating up to 46 megawatts. A third (steam) turbine can generate an additional 30 megawatts.
As of January 2018, the plant is no longer actively generating electricity. It previously supplied electricity to the provincial grid via the Independent Electricity System Operator (IESO) under a long-term contract with Ontario Electricity Financial Corporation (OEFC).
The plant is located adjacent to Toronto’s Pearson International Airport in Mississauga, Ontario.
The Mississauga plant is a cogeneration facility, meaning electricity and steam are produced simultaneously from a single energy source – in this case, natural gas. Heat from the gas turbines is used to create steam which industrial customers can use in their own operations. Creating two products from one fuel source improves plant efficiency.
The plant also uses steam injection for NOx control.
