The Tennessee Valley Authority (TVA) is a federally owned electric utility corporation in the United States. TVA's service area covers all of Tennessee, portions of Alabama, Mississippi, and Kentucky, and small areas of Georgia, North Carolina, and Virginia. While owned by the federal government, TVA receives no taxpayer funding and operates similarly to a private for-profit company. It is headquartered in Knoxville, Tennessee, and is the sixth-largest power supplier and largest public utility in the country.
A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal, oil, or natural gas, to produce electricity. Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator. The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine. All plants use the energy extracted from the expansion of a hot gas, either steam or combustion gases. Although different energy conversion methods exist, all thermal power station conversion methods have their efficiency limited by the Carnot efficiency and therefore produce waste heat.
Cumberland Fossil Plant is a pulverized coal-fired power station located west of Cumberland City, Tennessee, US, on the south bank of Lake Barkley on the Cumberland River. Owned and operated by Tennessee Valley Authority (TVA), it has a gross capacity of 2,470 MW, and is the most powerful power station in Tennessee.
Kingston Fossil Plant, commonly known as Kingston Steam Plant, is a 1.4-gigawatt coal-fired power plant located in Roane County, just outside Kingston, Tennessee, on the shore of Watts Bar Lake. It is operated by the Tennessee Valley Authority. The plant is known for the Kingston Fossil Plant fly ash spill which occurred in December 2008.
Cottam power station is a decommissioned coal-fired power station. The site extends over 620 acres (250 ha) of mainly arable land and is situated at the eastern edge of Nottinghamshire on the west bank of the River Trent at Cottam near Retford. The larger coal-fired station was decommissioned by EDF Energy in 2019 in line with the UK's goal to meet its zero-coal power generation by 2025. The smaller in-use station is Cottam Development Centre, a combined cycle gas turbine plant commissioned in 1999, with a generating capacity of 440 MW. This plant is owned by Uniper.
Bull Run Fossil Plant, commonly known as Bull Run Steam Plant, is a decommissioned 889 megawatt (MW), coal-fired electric generating station owned and operated by the Tennessee Valley Authority (TVA). The plant is the only coal fired power plant ever constructed by TVA with one unit, and was retired on December 1, 2023.
James M. Barry Electric Generating Plant, also known as Barry Steam Plant or Plant Barry, is a coal- and natural gas-fired electrical generation facility in Bucks, Mobile County, Alabama, United States. It lies on the west bank of the Mobile River, using it both for coal delivery as well as for cooling water. The plant was named for James M. Barry, President of Alabama Power Company from 1949 to 1952. As of 2018, the plant has 9 units, seven of which are powered by gas and two which are powered by coal.
The Dan River Steam Station is a power plant in Eden, North Carolina, owned by Duke Energy. The plant comprises three natural gas-fueled combustion turbines, which began operation in 1968.), and two natural gas-fueled combined cycle turbines are planned for the near future. A coal-fired electrical power plant at the site ceased operation in 2012.
The Shawnee Fossil Plant is a coal-fired power plant owned and operated by the Tennessee Valley Authority, located near Paducah, Kentucky. The closest city is Metropolis, Illinois, across the Ohio River to the northeast. The Shawnee Fossil Plant was created with the intentions of providing sufficient electricity to the national defense industry escalating demand for power which could not be met with the Commonwealth of Kentucky's then-current infrastructure. The plant also provided economic growth to the area in the post-WWII era creating jobs and a stronger infrastructure to support future state developments.
The Paradise Combined Cycle Plant is a natural gas power plant operated by the Tennessee Valley Authority (TVA). Located just east of Drakesboro, Kentucky, it was the highest power capacity power plant in Kentucky. The plant originally consisted of three coal units, with a combined capacity of 2,632 MW. Units 1 and 2 were retired in 2017, and replaced with the natural gas units, and Unit 3 was retired in 2020. The combined cycle natural gas plant had a capacity of 1.02-gigawatts as of 2017.
The Johnsonville Combustion Turbine Plant is a 1.2-gigawatt, simple cycle natural gas power plant located in New Johnsonville, Tennessee in Humphreys County, Tennessee. It is operated by the Tennessee Valley Authority (TVA).
The Johnsonville Fossil Plant was a 1.5-gigawatt, coal power plant located in New Johnsonville, Humphreys County, Tennessee, United States. The plant generated electricity from 1951 to 2017. It was operated by the Tennessee Valley Authority (TVA).
The Allen Combined Cycle Plant is a 1.1-gigawatt natural gas power plant located south of Memphis, Tennessee that began generating electricity in 2018. It is operated by Tennessee Valley Authority (TVA).
The Allen Fossil Plant was a 741-megawatt (MW), coal power plant located south of Memphis, Tennessee. It generated electricity from 1959 to 2018. At the time of its closure, the plant was operated by Tennessee Valley Authority (TVA).
Watts Bar Steam Plant was a 267-megawatt (MW), coal power plant operated by the Tennessee Valley Authority (TVA) located in Rhea County, Tennessee near the present site of Watts Bar Nuclear Plant and Watts Bar Dam. The plant was the first coal-fired power plant constructed by TVA.
Cherokee Generating Station is a natural gas-fired power plant in Adams County, Colorado, about 5 miles north of downtown Denver. Cherokee currently has a nameplate capacity of 1006.4 megawatts, and a net summer capacity of 886 megawatts, making it the largest power plant in Adams County, and the second largest natural-gas fired plant in the state behind Fort St. Vrain Generating Station. In 2022, Cherokee output a total of 3.2 billion kilowatt-hours of electricity, representing roughly 5 percent of total electricity generation in Colorado. Cherokee is composed of four power generating units: one standalone natural gas fired steam turbine, two natural gas fired combustion turbines, and one steam turbine sourcing its heat from the exhaust of the two combustion turbines. This configuration is known as a combined cycle natural gas power plant. In 2022, the overall thermal efficiency of the steam turbine unit was 31.3%, compared to 43.2% of the combined cycle units. Efforts have been made to reduce the amount of water consumed, most likely from evaporation in the cooling towers. The combined cycle units were constructed in 2015, adding another 625.6 megawatts of nameplate capacity to the steam turbine's 380.8 MW. Prior to 2017, the steam turbine unit was almost entirely powered by coal, however it made the shift to only natural gas that year, and has not burned coal since. The change was partly due to the Clean Air Act of 2010, which had the focus of reducing emissions from coal power plants, however other factors such as the inexpensive price of natural gas and pressure for the state to transition away from coal also played parts.
The Colbert Combustion Turbine Plant is a combustion turbine natural gas-fired power plant operated by the Tennessee Valley Authority (TVA) near Tuscumbia, Alabama. Commissioned in 1972, it is currently the oldest gas-fired power plant operated by TVA. The site was formerly home to the Colbert Fossil Plant, a coal-fired power station which operated from 1955 to 2016.
The W.S. Lee Steam Station, which was previously called the Lee Steam Station, is an electric generation station located near Williamston, South Carolina on the Saluda River. It was named for William States Lee who was chief engineer of Duke Power. He is the grandfather of William States Lee III, who was a chairman and president of Duke Power.
