Power Plant Stack Emissions. Emissions from the Mandalay Power Plant are released into the atmosphere. These include nitrogen oxides and carbon dioxide, although in smaller quantities than those released from coal power plants. The Mandalay Station features three generating units: two steam-powered units that were commissioned in 1959 and one jet engine-powered unit that was commissioned in 1970. Fuelled by natural gas, the plant can contribute up to 560 megawatts of electricity. The state-of-the-art facility is among the first in the world to use selective catalytic reduction technology to minimize emissions.* *Source: reliant.com
