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.
Langage Power Station is a combined-cycle power plant near the city of Plymouth in Devon, England.
The Bell Bay Power Station was a power station located in Bell Bay, on the Tamar River, Tasmania, Australia, adjacent to the Tamar Valley Power Station, with which it was often confused. It was commissioned between 1971 and 1974 as an oil fired thermal power station, and was converted to natural gas in 2003, after the commissioning of the Tasmanian Gas Pipeline, a submarine gas pipeline which transports natural gas from Longford, Victoria, under Bass Strait, to Bell Bay, Tasmania. As the power station's primary role was to provide system security in the event of drought for Tasmania's predominantly hydro-electric based generation system it only was rarely called on to operate, resulting in intervals of five to eight years between periods of significant use. After the commissioning of Basslink in 2006, the power station was decommissioned in 2009.
Callide Power Station is located near Biloela, in Central Queensland, Australia. It is coal powered with eight steam turbines with a combined generation capacity of 1,720 megawatts (MW) of electricity. Callide A was commissioned in 1965, refurbished in 1998 and decommissioned in 2015/16. As of 2018, generation capacity was 1510 MW.
Thorpe Marsh Power Station was a 1 GW coal-fired power station near Barnby Dun in South Yorkshire, England. The station was built in 1959 and closed in 1994. In 2011, permission was given for the construction of a gas-fired power station on the site.
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.
The Kogan Creek Power Station is a 750 megawatt coal fired power station owned by CS Energy on the Darling Downs in Queensland. The $1.2 billion plant is situated at Brigalow, in the Surat Basin between Dalby and Chinchilla.
Condamine Power Station is a 140 MW combined cycle power station near Miles on the western Darling Downs in Queensland, Australia. The station is located 8 kilometres (5.0 mi) east of Miles on the south side of the Warrego Highway. The Condamine Power Station is owned by QGC Limited, a subsidiary of Royal Dutch Shell. It has been claimed to be the world’s first combined-cycle power station entirely fired by untreated coal seam gas and Australia's first steam turbine condenser cooled by coal seam methane waste water. However, the Townsville Power Station at Yabulu, which was converted from a peak load power station to burn only coal seam gas in a combined cycle configuration, was commissioned much earlier, in February 2005.
Edwardsport Power Station is a 618 MW Integrated gasification combined cycle (IGCC) coal based power plant in Vigo Township, Knox County, near the town of Edwardsport, Indiana. The integrated gasification combined cycle power plant construction started in June 2008 by Duke Energy near the site of an older 160 MW coal-fired electrical power plant, which was decommissioned in 2010.
The Dickerson Generating Station is an 853 MW electric generating plant owned by NRG Energy, located approximately two miles west of Dickerson, Maryland.
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.
Thor Cogeneration is a planned, but undeveloped, gas-fired cogeneration plant, which was to be built on Seal Sands near Billingham, in County Durham, North East England.
Darling Downs Power Station is in Kogan, Western Downs Region, Queensland, Australia. It is 40 kilometres (25 mi) west of Dalby and owned by Origin Energy. The Darling Downs Power Station is adjacent to the QLD-NSW high voltage transmission Interconnector and the Powerlink Queensland R2 Braemar 330/275 kV Substation.
Braemar Power Station is a complex of natural gas and coal seam gas fired combined-cycle power stations in Kogan, Western Downs Region, Queensland, Australia. It is near Dalby in the Darling Downs region.
The Takoradi Power Station is a thermal power station at Aboadze, 17 kilometres (11 mi) east of Sekondi-Takoradi, Ghana. It consists of three power plants.

Energy in Jordan describes energy and electricity production, consumption and import in Jordan. Jordan is among the highest in the world in dependency on foreign energy sources, with 96% of the country's energy needs coming from imported oil and natural gas from neighboring Middle Eastern countries. This complete reliance on foreign oil imports consumes a significant amount of Jordan's GDP. This led the country to plan investments of $15 billion in renewable and nuclear energy. To further address these problems, the National Energy Strategy for 2007-2020 was created which projects to boost reliance on domestic energy sources from 4 per cent to 40 per cent by the end of the decade.
Diamantina Power Station is a combined-cycle gas turbine electricity generation plant in Mount Isa, Queensland. It was developed by APA Group and AGL Energy at a cost of $570 million. Siemens Energy supplied two blocks each with one steam turbine, two gas turbines and two heat-recovery steam generators, with supplementary firing burners.
