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.
Ballylumford power station "C" station is a natural-gas-fired power station in County Antrim, Northern Ireland, UK. With its main plant generating almost 700 megawatts of electricity, it is Northern Ireland's largest power station and provides half its power. Overall the station can produce 693 MW. The plant is located at the tip of the Islandmagee peninsula, which separates Larne Lough from the Irish Sea. The lough is a Site of Special Scientific Interest. The 3 chimneys of the now decommissioned "B" station are 126 metres tall. East of the station is the Ballycronan More converter station, the Northern Ireland end of the Moyle Interconnector, a subsea HVDC interconnector connecting the NI electricity system to Great Britain.
Langage Power Station is a combined-cycle power plant near the city of Plymouth in Devon, England.
Poolbeg Generating Station, colloquially known as The Poolbeg Stacks, is a power station owned and operated by the Electricity Supply Board of Ireland (ESB). There are two stations on the site, the older thermal station containing units 1, 2, and 3 and the combined cycle gas station containing units CG14, CG15 and ST16, which is located toward the eastern end of the site. The six units have a total installed capacity of 1020 MW.
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.
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.
Keadby Power Stations are a pair of natural gas-fired power stations near Scunthorpe in North Lincolnshire, built on the site of an older coal power station. The site lies near the B1392 and the River Trent, and the Scunthorpe-Grimsby railway. Also nearby is the Stainforth and Keadby Canal, which is part of the Sheffield and South Yorkshire Navigation. The current stations are operated by SSE Thermal.
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.
Coryton Power Station is a 732 MW Combined Cycle Gas Turbine (CCGT) gas-fired power station at Coryton, Thurrock, Essex, UK.
Medway Power Station is a 735 megawatts gas-fired combined cycle gas turbine (CCGT) power station on the Isle of Grain in Kent adjacent to the River Medway, about 44 miles east of London. It started to supply electricity to the national grid in 1995.
Deeside Power Station is a power station on the Deeside Industrial Park to the north of Connah's Quay in Flintshire, Wales. Constructed as a 498 MWe combined-cycle gas plant, it is now used to provide inertial response and reactive power services to the grid.
Staythorpe C Power Station is a 1,735 MWe gas-fired power station at Staythorpe between Southwell and Newark-on-Trent in Nottinghamshire, England, between the River Trent and Nottingham to Lincoln railway line. The station was handed over to the owner RWE from Alstom Power with full commercial operation being achieved in December 2010. The official opening ceremony attended by Charles Hendry, Minister of State took place on 9 May 2011.
The Ōtāhuhu power station was a power station site located in Ōtara, Auckland, New Zealand. Two plants operated on the site: Ōtāhuhu A and Ōtāhuhu B. A proposed third station, Ōtāhuhu C, was never built. The stations were owned by Contact Energy.
Aghada is a village and civil parish in County Cork, Ireland. It is situated on the eastern side of Cork Harbour, around 12 km by road south of Midleton.
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.
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.
Ireland is a net energy importer. Ireland's import dependency decreased to 85% in 2014. The cost of all energy imports to Ireland was approximately €5.7 billion, down from €6.5 billion (revised) in 2013 due mainly to falling oil and, to a lesser extent, gas import prices. Consumption of all fuels fell in 2014 with the exception of peat, renewables and non-renewable wastes.
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.
Great Island Power Station is a gas fired and former heavy fuel oil fired power station situated near Waterford Harbour in Great Island, County Wexford, Ireland, that supplies electricity to more than 500,000 Irish homes. It is located at the confluence of the rivers Barrow and Suir, near Campile. The station opened in 1967 and was operated by the Electricity Supply Board (ESB) with three heavy fuel oil units and a total power of 240 MW since 1972. The station was scheduled to close by 2010, until it was sold to Endesa in January 2009. In October 2012, the plant was acquired by SSE Thermal.
