History
Construction of the Kingston Fossil Plant began on April 30, 1951. It was the largest coal-fired power plant in the world when completed in 1955. It was built primarily to provide electricity for the nearby Oak Ridge National Laboratory. A dedication ceremony for the plant took place on November 17, 1955. The plant is a popular site for birdwatching, birdwatchers, as many waterfowl come to the Settling basin, settling and treatment ponds nearby. The plant has nine generating units: Units 1–4, rated at 175 MW each (launched into service in 1954), and Units 5–9, rated at 200 MW each (launched in 1955). Combined, the plant has a total capacity of 1,700 MWe (1,398 MWe net). It produces about ten billion watt hour, kilowatt hours of electricity from some five million tons of coal each year. All nine generating units are equipped with selective catalytic reduction (SCR) systems to reduce nitrogen oxide () emissions that contribute to the formation of ozone. In 1976, its original nine stacks were taken out of service (though left standing) and replaced by a pair of 1,000-foot (304.8 meter) tall chimneys, one for Units 1–5 and one for Units 6–9. These stacks were replaced with a single stack connected to scrubbers which were installed in 2007.2008 spill
In December 2008, an coal slurry, impoundment at the plant failed, releasing of coal fly ash slurry that covered up to of the surrounding land, damaging homes and flowing into nearby waterways such as the Emory River and Clinch River, tributaries of the Tennessee River. This was the largest accidental release of coal fly ash in the United States.EPA compliance agreement
On April 14, 2011, the U.S. Environmental Protection Agency (EPA) announced a settlement with the Tennessee Valley Authority to resolve alleged Clean Air Act violations at 11 of its coal-fired plants in Alabama, Kentucky, and Tennessee. Under the terms of the agreement, Units 1–9 will continuously operate Selective Catalytic Reduction, Selective Catalytic Reduction (SCR) systems to reduce their emissions of .See also
