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.
Air-based CCGT systems have demonstrated very high availability and reliability. [6] The most notable helium-based system thus far was Oberhausen 2, a 50 megawatt cogeneration plant that operated from 1975 to 1987 in Germany. [7] Compared to Europe where the technology was originally developed, CCGT is not well known in the US. [8]
A 2014 Belgium study investigates what if scenarios for different mixes of nuclear generation, combined cycle gas turbine (CCGT) plant, and VRE and finds that the CCGT plants are subject to more aggressive cycling as renewable generation penetrates. [45]
The new CCGT was a major upgrade to the power station and provided a new base-load generating capacity to meet rising power demand in Ireland. [8] With a capacity of 435 MW the new CCGT brought the total capacity of the power plant from 528 MW to 963 MW. The CCGT generates enough power to meet the electricity needs of around 450,000 homes.

Grain CCGT power station has three Alstom GT26 gas turbines. The scheme is designed on three Alstom KA26 Single-Shaft Combined Cycle Power Plant Power Blocks; these include a STF30C reheat steam turbine, a heat recovery steam generator and a TOPGAS hydrogen-cooled turbogenerator each. [24] The GT26 gas turbines are a lean-premix, low NOx, machines.

The relatively low 59% efficiency of the Magnum plant means that more efficient CCGT plants (such as the Hemweg 9 plant) are preferred to provide (backup) power. A new generation of IGCC-based coal-fired power plants has been proposed, although none is yet under construction.
The station is currently Uniper's largest CCGT power station. As Connah's Quay is a CCGT power station, it runs on natural gas. The plant has four 330 MW modules - hence four chimneys. Each module has a General Electric Frame 9FA gas turbine, a Stein Industrie heat recovery steam generator and a steam turbine; in a single-shaft layout.
