Combined-Cycle
Combined-cycle power plants combine a gas turbine and a steam turbine to produce electricity from one fuel input.
A gas turbine turns an electrical generator. The hot exhaust gas from the turbine is captured in a heat recovery boiler where the majority of the heat is converted into steam. The steam is then injected into a steam turbine that turns another electricity generator, resulting in additional output of electricity from the one fuel input.
Combined-cycle plants operate at higher levels of efficiency than traditional
thermal generation and natural gas contributes considerably less to air pollution than conventional coal or oil-fired generation.
ATCO Powers combined-cycle plants include the 1,000-megawatt Barking Power Plant and the 580-megawatt Brighton Beach plant
in Ontario.
