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, using for example, the pumped-storage method.
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid.
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.
Navajo Generating Station was a 2.25-gigawatt, coal-fired power plant located on the Navajo Nation, near Page, Arizona, United States. This plant provided electrical power to customers in Arizona, Nevada, and California. It also provided the power for pumping Colorado River water for the Central Arizona Project, supplying about 1.5 million acre feet (1.85 km3) of water annually to central and southern Arizona. As of 2017 permission to operate as a conventional coal-fired plant was anticipated until 2017–2019, and to December 22, 2044, if extended. However, in 2017, the utility operators of the power station voted to close the facility when the lease expires in 2019. In March 2019, the Navajo Nation ended efforts to buy the plant and continue running it after the lease expires.
A thermal power station, also known as a thermal power plant, is a type of power station in which the heat energy generated from various fuel sources is converted to electrical energy. The heat from the source is converted into mechanical energy using a thermodynamic power cycle. The most common cycle involves a working fluid heated and boiled under high pressure in a pressure vessel to produce high-pressure steam. This high pressure-steam is then directed to a turbine, where it rotates the turbine's blades. The rotating turbine is mechanically connected to an electric generator which converts rotary motion into electricity. Fuels such as natural gas or oil can also be burnt directly in gas turbines, skipping the steam generation step. These plants can be of the open cycle or the more efficient combined cycle type.
Liddell Power Station is a decommissioned coal-fired thermal power station that had four 500 megawatts (670,000 hp) EE steam-driven turbine alternators, providing a combined electrical capacity of 2,000 megawatts (2,700,000 hp).
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.
The B.L. England Generating Station, also called Beesley's Point Generating Station, was a power plant in Upper Township, Cape May County, New Jersey, United States, on the Great Egg Harbor River. The facility provided approximately 450 megawatts of generating capacity from three generating units. Two units burned coal (and up to 7 percent Tire-derived fuel) and the third unit burned bunker C oil. Its large smokestack, altered to resemble a lighthouse, contained a sulfur dioxide scrubber which removed the SO2 from the flue gas and converted it into gypsum, which can be sold. The scrubber allowed the two coal units to use less expensive high sulfur coal from West Virginia.
The Robert W. Scherer Power Plant is a coal-fired power plant in Juliette, Georgia, just north of Macon, Georgia, in the United States. The plant has four generating units, each capable of producing 930 megawatts, and is the most powerful coal-fired plant in North America. The plant is named after the former chairman and chief executive officer of Georgia Power.
Independence Power Plant is a 1,678-megawatt coal-fired base load power plant near Newark, Arkansas. The plant has two units, rated at 850 MWe each, that came online in 1983 and 1984. The plant is owned in part by Entergy Arkansas. It has a 305-meter chimney built in 1983.
Niederaussem Power Station is a lignite-fired power station in the Bergheim Niederaussem/Rhein Erft circle, owned by RWE. It consisted of nine units, which were built between 1963 and 2003. It is the largest lignite coal power plant in operation in Germany, with total net capacity of 2,220 MW. The plant is estimated to have been one of the ten most carbon-polluting coal-fired power plants in the world in 2018, at 27.2 million tons of carbon dioxide, and its emissions intensity is estimated to be 45.1% higher relative to the average for all fossil-fueled plants in Germany. According to the study Dirty Thirty, issued in 2007 by the WWF, Niederaussem Power Station is the second-worst power station in Europe in terms of mercury emissions due to the use of lignite.
Mount Hope Bay is a tidal estuary located at the mouth of the Taunton River on the Massachusetts and Rhode Island border. It is an arm of Narragansett Bay. The bay is named after Mount Hope, a small hill located on its western shore in what is now Bristol, Rhode Island. It flows into the East Passage of Narragansett Bay and also the Sakonnet River. Mount Hope Bay has played an important role to the history of the area, from pre-colonial times to the present. While many years of sewage and industrial pollution have severely degraded the quality of the shallow waters of the bay, there are currently major efforts underway to clean up and restore it.
A gas-fired power plant, sometimes referred to as gas-fired power station, natural gas power plant, or methane gas power plant, is a thermal power station that burns natural gas to generate electricity. Gas-fired power plants generate almost a quarter of world electricity and are significant sources of greenhouse gas emissions. However, they can provide seasonal, dispatchable energy generation to compensate for variable renewable energy deficits, where hydropower or interconnectors are not available. In the early 2020s batteries became competitive with gas peaker plants.
Dominion Energy, Inc., commonly referred to as Dominion, is an American energy company headquartered in Richmond, Virginia that supplies electricity in parts of Virginia, North Carolina, and South Carolina and supplies natural gas to parts of Utah, Idaho and Wyoming, West Virginia, Ohio, Pennsylvania, North Carolina, South Carolina, and Georgia. Dominion also has generation facilities in Indiana, Illinois, Connecticut, and Rhode Island.

Megawatt Valley is a term applied to a geographic location which houses a large number of electricity generating stations. Historically in the United Kingdom this applied to the coal-fired power stations of the lower Trent Valley. In the mid-1980s, the valley's 13 facilities generated up to a quarter of the power demand for England and Wales. A shift to gas-fired power stations saw many of the Megawatt Valley facilities close down. The term was then associated with an area of Yorkshire centred on the River Aire that was home to Ferrybridge C, Eggborough and Drax power stations. Of these facilities only Drax remains in operation. In the United States the term has been applied to an area of West Virginia, home to five power stations.
