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 combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy. On land, when used to make electricity the most common type is called a combined cycle gas turbine (CCGT) plant, which is a kind of gas-fired power plant. The same principle is also used for marine propulsion, where it is called a combined gas and steam (COGAS) plant. Combining two or more thermodynamic cycles improves overall efficiency, which reduces fuel costs.
Cogeneration or combined heat and power (CHP) is the use of a heat engine or power station to generate electricity and useful heat at the same time.
Puget Sound Energy, Inc. (PSE) is an energy utility company based in the U.S. state of Washington that provides electrical power and natural gas to the Puget Sound region. The utility serves electricity to more than 1.2 million customers in Island, King, Kitsap, Kittitas, Pierce, Skagit, Thurston, and Whatcom counties, and provides natural gas to 877,000 customers in King, Kittitas, Lewis, Pierce, Snohomish and Thurston counties. The company's electric and natural gas service area spans 6,000 square miles (16,000 km2).
The Portlands Energy Centre is a 550-megawatt natural gas electrical generating station in Toronto, Ontario. It is located in the Port Lands area of the Toronto waterfront at 470 Unwin Avenue, adjacent to the site of the decommissioned Hearn Generating Station.
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.
The Lakeview Generating Station was an Ontario Power Generation coal-burning power station located in Mississauga, Ontario, Canada, in the Lakeview neighbourhood on Lakeshore Road just east of Cawthra Road. The former station, constructed in 1958–1962, had four smokestacks known as the Four Sisters; the eight boilers of the generating plant all 'twinned' their emissions into common stacks. The station was a landmark for years and was shut down in April, 2005, after 43 years of service. The four stacks, which could be seen from as far away as Burlington to the west and downtown Toronto to the east, were demolished on June 12, 2006. The rest of the building was demolished on June 28, 2007.
Teesside Power Station is a former gas-fired power station, in Redcar & Cleveland, England. Situated near the Wilton chemical complex, the station had combined cycle gas turbines (CCGTs) and open cycle gas turbines (OCGTs), however in 2011 the operation of the CCGT part of the station was suspended, and in 2013 the owners announced its closure and plans to demolish it. Prior to the suspension, the station had a generating capacity of 1875 megawatts (MW), making it the largest of any CCGT power station in Europe. The station could meet almost 3% of the electricity demand for England, Wales and Scotland. Opened in 1993, the station was initially operated by Enron but moved into the hands of PX Ltd after the Enron scandal of 2001, before being bought by Gaz de France and Suez in 2008. The station also worked as a cogeneration plant, providing steam for the Wilton complex.
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.
King's Lynn Power Station refers to a combined cycle natural gas power station near King's Lynn in Norfolk, commissioned in 1997, and now owned by RWE, and to a coal fired power in King's Lynn in operation from 1899 to 1960. The CCGT station was mothballed on 1 April 2012. It can generate 325 MW of electricity and employed 40 people. The site was reopened on 19 November 2019.
Coolkeeragh power station is a power station near Derry in Northern Ireland.
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.
Glanford Brigg Power Station is a gas-fired power station in North Lincolnshire, England. It is capable of firing diesel as a substitute of natural gas. It is situated on the River Ancholme, beside the Sheffield to Cleethorpes via Brigg Line, outside the town of Brigg, with its name coming from the former name for the town. It has a generating capacity of 240 megawatts (MW).
Little Barford Power Station is a combined cycle gas turbine power station in 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.
Shoreham Power Station is a 420MWe combined cycle gas-fired power station in Southwick, West Sussex. It was built on the site of the Shoreham B Power Station.
The Gould Street Generating Station was a former 100 MW electric generating plant operated by Exelon that was located on Gould Street in south Baltimore, Maryland, USA. The plant was adjacent to an elevated section of freeway I-95 and was south of the Riverside neighborhood and west of the Locust Point neighborhood of Baltimore. The plant site, located on the shore of the Middle Branch of the Patapsco River, was used for the generation of electric power for over one hundred years before being shut down on June 1, 2019. The site was purchased by Greenspring Realty Partners, Inc. for $3.1 million in December 2019. Demolition began in October 2020. The original brick buildings, the large storage tanks behind them, and other minor structures on the southwest portion of the property were demolished as of March 2021, but as of April 2022 the larger steel building to the northeast on the property remains. A large portion of the property was acquired by Weller Development in July 2021 and the future of the remaining structure and the property is not known.
Martin Next Generation Solar Energy Center is the solar parabolic-trough component of an integrated solar combined cycle (ISCC) 1150 MW plant, in western Martin County, Florida, United States, just north of Indiantown.
