Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry, it is the stage prior to its delivery to end users or its storage.
A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal 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.
American Electric Power Company, Inc. (AEP), is a major investor-owned electric utility in the United States, delivering electricity to more than five million customers in 11 states.
The William H. Zimmer Power Station, located near Moscow, Ohio, was a 1.35-gigawatt coal power plant. Planned by Cincinnati Gas and Electric (CG&E), with Columbus & Southern Ohio Electric and Dayton Power & Light (DP&L) as its partners, it was originally intended to be a nuclear power plant. Although once estimated to be 97% complete, poor construction and quality assurance (QA) led to the plant being converted to coal-fired generation. The plant began operations in 1991. Today, the plant is owned and operated by Vistra Corp.
The Keystone Generating Station is a 1.71-gigawatt, coal power plant located on roughly 1,500 acres (610 ha) in Plumcreek Township, southeastern Armstrong County, Pennsylvania near Crooked Creek, just west of Shelocta, Pennsylvania.
Baglan Bay power station is a disused 525MWe gas-fired power station situated on Baglan Moors just west of Port Talbot in Wales.
MAPNA Group is a group of Iranian companies involved in development and execution of thermal and renewable power plants, oil & gas, railway transportation and other industrial projects as well as manufacturing main equipment including gas and steam turbines, electrical generator, turbine blade and vane, HRSG and conventional boilers, electric and control systems, gas compressor, locomotive and other pertinent equipment.
Damhead Creek power station is a 792 MWe gas-fired power station in Kent, England, on the Hoo Peninsula, It is near the site of the decommissioned Kingsnorth power station. The plant entered service in February 2001.
Spalding Power Station is a 860 MW gas-fired power station one mile north of Spalding on West Marsh Road close to the River Welland. The current site provides enough electricity for one million households.
Sutton Bridge Power Station is an 819 MW gas-fired power station in Sutton Bridge in the south-east of Lincolnshire in South Holland, England. It is situated on Centenary Way close to the River Nene. It is a major landmark on the Lincolnshire and Norfolk border and on clear days with its bright red lights it can be easily seen as far away as Hunstanton.
Little Barford Power Station is a gas-fired power station just north of the village of Little Barford in Bedfordshire, England. It lies just south of the A428 St Neots bypass and east of the Wyboston Leisure Park. The River Great Ouse runs alongside. It was formerly the site of two coal-fired power stations, now demolished. The station is operated by RWE.
Medway Power Station is a 735 megawatts gas-fired combined cycle gas turbine (CCGT) power station on the Isle of Grain in Kent adjacent to the River Medway, about 44 miles east of London. It started to supply electricity to the national grid in 1995.
John E. Amos Power Plant is a three-unit coal-fired power plant owned and operated by Appalachian Power, a subsidiary of American Electric Power (AEP). With a nameplate rating of 2,933 MW, it is the largest generating plant in the AEP system. It was named after John E. Amos, a prominent state senator, Democratic National Committee member from West Virginia, and member of the AEP board of directors.
The Grand River Dam Authority (GRDA) is an agency of the state of Oklahoma created to control, develop, and maintain the Grand River waterway. It was created by the Oklahoma state legislature in 1935, and is headquartered in Tulsa, Oklahoma. GRDA was designed to be self-funding from the sales of electricity and water. The state of Oklahoma was to provide no funding from taxes. The Authority was authorized to issue revenue bonds to fund large-scale capital investments.
Coal gasification is a process whereby a hydrocarbon feedstock (coal) is converted into gaseous components by applying heat under pressure in the presence of steam. Rather than burning, most of the carbon-containing feedstock is broken apart by chemical reactions that produce "syngas." Syngas is primarily hydrogen and carbon monoxide, but the exact composition can vary. In Integrated Gasification Combined Cycle (IGCC) systems, the syngas is cleaned and burned as fuel in a combustion turbine which then drives an electric generator. Exhaust heat from the combustion turbine is recovered and used to create steam for a steam turbine-generator. The use of these two types of turbines in combination is one reason why gasification-based power systems can achieve high power generation efficiencies. Currently, commercially available gasification-based systems can operate at around 40% efficiencies. Syngas, however, emits more greenhouse gases than natural gas, and almost twice as much carbon as a coal plant. Coal gasification is also water-intensive.
Cardinal Power Plant is a 1.8-gigawatt coal power plant located south of Brilliant, Ohio, in Jefferson County, Ohio. The power plant has three units. Cardinal is co-owned with Unit 1 owned by American Electric Power's (AEP) subsidiary, AEP Generation Resources. Units 2–3 are owned by Buckeye Power, a utility cooperative. It began operations in 1967.
Conesville Power Plant was a 2-gigwatt, coal power plant located east of Conesville, Ohio in Coshocton County, Ohio. Its units were co-owned at the time of its closing by American Electric Power (AEP) and AES Ohio Generation. All plant operations were handled by AEP. Conesville began operations in 1957 and ceased generation in April 2020.
The Hanging Rock Energy Facility is a 1.43-gigawatt, natural gas power plant located west of Hanging Rock, Ohio in Lawrence County, Ohio. The plant began operations in 2003 and is currently owned by Vistra Energy.
Philo Power Plant was a 510 megawatt (MW), coal power plant located in Philo in Muskingum County, Ohio. It was the first power plant in the United States to apply steam reheat and supercritical steam generator technologies for its turbines. The plant had six units and its operations were handled by Ohio Power, a forerunner of American Electric Power (AEP). It operated from 1924 until ceasing in 1975.
Gateway Generating Station (GGS), formerly Contra Costa Unit 8 Power Project, is a combined-cycle, natural-gas-fired power station in Contra Costa County, California, which provides power to half a million customers in northern and central California. Gateway Generating Station is on the southern shore of the San Joaquin River, in Antioch, and is one of more than ten fossil-fuel power plants in Contra Costa County.
