• Jointly owned by Capital Power and TransAlta.
• 495-gross-megawatt (MW) (450-MW net) coal-fired generating facility.
• Construction led by Capital Power. Plant operated by TransAlta.
• Capital Power and TransAlta independently dispatch and market their share of the unit’s electrical output.
• Located approximately 70 km west of Edmonton, Alberta, adjacent to TransAlta’s Keephills power plant.
• One of Canada’s cleanest, most advanced coal-fired facilities.
Superior environmental performance through an advanced air-quality-control system and supercritical boiler technology.
Emits 24% less carbon dioxide when producing the same amount of power previously generated by the Wabamun units retired by TransAlta in 2010.
Reduced emissions of sulphur dioxide (SO2), nitrous oxides (NOx), and mercury by 60% to 80%.
A flue-gas desulphurization unit for removing SO2 from the flue gas.
Low NOx staged burners to reduce NOx emissions.
A mercury emission control system, likely using activated carbon injection technology.
Construction of Keephills 3 began in February 2007. At its peak, the project was regarded as one of Canada’s top ten biggest infrastructure projects, with a peak workforce of nearly 1,900 in March 2010. The project’s safety record was one of the best in the industry.
