Tall chimneysEdit
It has two of the tallest chimneys in the world at 1,001 feet (305 m), built in 1970.
Individual unitsEdit
Its identical Units 1 and 2, rated at 1.3 GW each, were launched into service in March and November, 1973. In 2004, the two units accounted for almost 12% of TVA's total electricity generation.
Coal deliveryEdit
Bituminous coal is delivered by barges along the Cumberland River waterway. The plant consumes about 20,000 tons of coal a day.
Water useEdit
All of the waste heat is dumped into Cumberland River water.
Environmental protection measuresEdit
To reduce sulfur dioxide (SO2) emissions, both units at Cumberland use wet limestone scrubbers. To reduce nitrogen oxides (NOx), the units use low-NOx burners as well as selective catalytic reduction systems, which were completed in 2004.
