Mississauga Cogeneration Plant is a natural gas power station partially owned by TransAlta and located within Toronto Pearson International Airport. The plant is primarily used to supply steam and power to nearby industrial clients with surplus power sold onto the Ontario grid. From 1992 to 2007, it supplied thermal energy to the McDonnell Douglas and later Boeing aircraft parts plant.
The plant is located across near Airport Road and Derry Road next to the former Boeing aircraft plant (now demolished).
