Cumberland Power Plant at Cumberland City

Cumberland Power Plant is a 2.6-GW pulverized coal-powered power station located at 36°23′29″N 87°39′17″W / 36.39139°N 87.65472°W / 36.39139; -87.65472Coordinates: 36°23′29″N 87°39′17″W / 36.39139°N 87.65472°W / 36.39139; -87.65472 in Cumberland City, Tennessee, USA, on the south bank of Lake Barkley on the Cumberland River. Owned and operated by Tennessee Valley Authority (TVA), it produces the most electricity of all plants in the TVA system.[1]

Tall chimneys[edit]

It has two of the tallest chimneys in the world at 1,001 feet (305 m), built in 1970.

Individual units[edit]

Its identical Units 1 and 2, rated at 1.3 GW each, were launched into service in March and November, 1973.[2] In 2004, the two units accounted for almost 12% of TVA's total electricity generation.[1]

Coal delivery[edit]

Bituminous coal is delivered by barges along the Cumberland River waterway. The plant consumes about 20,000 tons of coal a day.[1]

Water use[edit]

All of the waste heat is dumped into Cumberland River water.

Environmental protection measures[edit]

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.[1]
