Cogeneration

Cogeneration is a process that generates electricity while capturing the waste heat from generation for other productive uses. The captured waste heat is utilized in an adjacent process avoiding the use of additional fuel to generate the required heat. Cogeneration lowers emissions to the environment, particularly carbon dioxide by capturing and recycling waste heat, and can be highly efficient.

ATCO Power is involved in several  cogeneration projects including Joffre, Primrose, McMahon,  Bulwer Island, Heathrow, Osborne, Rainbow, Scotford, Muskeg River and Cory. In these projects, a gas turbine turns an electrical generator. The hot exhaust gas from the turbine is captured in a heat recovery boiler where the heat is converted to steam. The steam is used in an adjacent process.
