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.
Puget Sound Energy (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 1.1 million customers in Island, King, Kitsap, Kittitas, Pierce, Skagit, Thurston, and Whatcom counties, and provides natural gas to 750,000 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 Mount Stuart Power Station is a power station located in Stuart, Townsville, Australia. The station runs on kerosene with three gas turbines that generate a combined capacity of 414 MW of electricity. Mount Stuart was commissioned in December 1998, and operates as a peaking plant. It currently runs on kerosene, but can be converted to natural gas.
Solar power is a fast growing industry in Australia. As of September 2022, Australia's over 3.27 million solar PV installations had a combined capacity of 28,177 MW photovoltaic (PV) solar power, of which at least 4,258 MW were installed in the preceding 12 months. In 2019, 59 solar PV projects with a combined capacity of 2,881 MW were either under construction, constructed or due to start construction having reached financial closure. Solar accounted for 9.9% of Australia's total electrical energy production in 2020.
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.
Chubu Electric Power Co., Inc., abbreviated as Chuden in Japanese, is a Japanese electric utilities provider for the middle Chūbu region of the Honshu island of Japan. It provides electricity at 60 Hz, though an area of Nagano Prefecture uses 50 Hz. Chubu Electric Power ranks third among Japan's largest electric utilities in terms of power generation capacity, electric energy sold, and annual revenue. It is also one of Nagoya's "four influential companies" along with Meitetsu, Matsuzakaya, and Toho Gas. Recently, the company has also expanded into the business of optical fibers. On January 1, 2006, a new company, Chubu Telecommunications, was formed.
Geothermal power is electrical power generated from geothermal energy. Technologies in use include dry steam power stations, flash steam power stations and binary cycle power stations. Geothermal electricity generation is currently used in 26 countries, while geothermal heating is in use in 70 countries.
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.
Tamar Valley Power Station is a $230 million natural gas-fired power station located in Bell Bay in the Tamar Valley, Tasmania. It is owned by Hydro Tasmania, and is immediately adjacent to the decommissioned Bell Bay Power Station, which is also owned by Hydro Tasmania.
Indraprastha Power Generation Company Limited (IPGCL) is the electricity generation company of the Government of Delhi state in India.
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 McKee power station is a gas-fired generating plant located at the McKee production station in north Taranaki, New Zealand. The plant currently comprises two 50 MW gas turbines in open cycle mode and two 1 MW reciprocating engines in cogeneration mode. It is owned and operated by Nova Energy.
The provision of electricity in Queensland required a considerable degree of pioneering, innovation, and commitment. Queensland proved to be a pioneer in the supply of electricity in Australia, with the first public demonstration in Australia, the first recorded use for public purposes in the country, the first Parliament House in Australia and the first commercial operations in Australia all occurring in Brisbane.
Pragati-III Combined Cycle Power Plant is located at Bawana Delhi, India. The power plant is one of the gas based power plants of Pragati Power Corporation Limited (PPCL). The source of water for the power plant is treated water from Rithala Sewage Treatment Plant.
The Kelanitissa Power Station is a state-owned power station located on the south bank of the Kelani River in the northern part of the city of Colombo, Sri Lanka. Commissioned in 1964, it is the first thermal power station built in Sri Lanka, after the country gained independence. The facility has a current gross installed capacity of 360 MW, a significant amount when compared to the total installed capacity of nearly 4,086 MW in the year 2017. The facility is owned and operated by the Ceylon Electricity Board.
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.
