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. 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.
A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process (cogeneration) or used to drive a steam turbine.
A thermal power station is a type of power station in which heat energy is converted to electrical energy. In a steam-generating cycle heat is used to boil water in a large pressure vessel to produce high-pressure steam, which drives a steam turbine connected to an electrical generator. The low-pressure exhaust from the turbine enters a steam condenser where it is cooled to produce hot condensate which is recycled to the heating process to generate more high pressure steam. This is known as a Rankine cycle.
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.
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.
The Westinghouse Combustion Turbine Systems Division (CTSD), part of Westinghouse Electric Corporation's Westinghouse Power Generation group, was originally located, along with the Steam Turbine Division (STD), in a major industrial manufacturing complex, referred to as the South Philadelphia Works, in Lester, Pennsylvania near to the Philadelphia International Airport.
Coolkeeragh power station is a power station near Derry in Northern Ireland.
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.
Seabank Power Station is a 1,140 MW gas-fired power station at Hallen Marsh in Bristol, England. It is situated beside the A403 road and Severn Estuary, just north of Avonmouth and south of Severn Beach, close to the boundary with South Gloucestershire. It is next to the former Terra Nitrogen Severnside fertiliser works, which was closed by Growhow UK in January 2008.
Medway Power Station is a 735 megawatts gas-fired power station on the Isle of Grain in Medway next to the River Medway.
Shoreham Power Station is a 420MWe combined cycle gas-fired power station in Southwick, West Sussex. It was built on the site of the Brighton B Power Station.
Barry Power Station was a 230 MWe gas-fired power station on Sully Moors Road in Sully in the Vale of Glamorgan, Wales. It was eight miles west of Cardiff and was situated next to a large Ineos Vinyls chemicals works that makes PVC and a Hexion Chemicals plant.
Carrington Power Station is a combined cycle gas turbine power station, which was completed in Autumn 2016 and began commercial operation on 18 September 2016. It is located on the site of a former coal-fired power station, close to the villages of Carrington and Partington in the Greater Manchester Area and 12 km (7.5 mi) southwest of Manchester City Centre. The Manchester Ship Canal and the River Mersey run alongside the site, in Trafford, Greater Manchester, in North West England.
A waste heat recovery unit (WHRU) is an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process for some purpose, usually increased efficiency. The WHRU is a tool involved in cogeneration. Waste heat may be extracted from sources such as hot flue gases from a diesel generator, steam from cooling towers, or even waste water from cooling processes such as in steel cooling.
Repowering is the process of replacing older power stations with newer ones that either have a greater nameplate capacity or more efficiency which results in a net increase of power generated. Repowering can happen in several different ways. It can be as small as switching out and replacing a boiler, to as large as replacing the entire system to create a more powerful system entirely. There are many upsides to repowering.
Sarnia Regional Cogeneration Plant is a natural gas power station owned by TransAlta Energy, in Sarnia, Ontario. The plant is primarily used to supply steam to Arlanxeo, Styrolution, Suncor and Nova Chemicals and power onto the Ontario Grid.
Joffre Cogeneration Plant is a natural gas power station owned by Heartland Generation Ltd. (40%), Capital Power (40%) and Nova Chemicals (20%). The plant is located in Joffre, Alberta, Canada, near Red Deer. The plant is primarily used to supply steam to the adjacent Nova Chemicals processing plant.
GIPCL Vadodara Gas based Power Station is Gas turbine based combined cycle power plant. It is located at Dhanora village in Vadodara, Gujarat. The power plant is run by state-owned Gujarat Industrial Power Corporation Limited (GIPCL). The primary electricity generation is through the Gas turbines. Waste heat from the gas turbine is recovered by a heat recovery steam generator (HRSG) to power a conventional steam turbine. The HRSG recovers heat from a hot gas stream and produces steam, the steam utilized to power the steam turbines.
Whitegate power station is a 445 MW combined cycle gas turbine (CCGT) electricity generating station near Whitegate, County Cork in Ireland. It was commissioned in 2010 and can supply up to ten percent of the electricity demand in Ireland.
