A combined cycle gas turbine (CCGT) is a type of power generation system that combines two different thermodynamic cycles to produce electricity while pushing efficiency. As such, the combined cycle gas turbine model involves the integration of a gas turbine cycle and a steam turbine cycle, which work together to extract energy from a fuel

This article was published by the US Energy Information Administration on Nov. 4, 2022. By Mark Morey. CCGT plants are one of four major sources of natural gas-fired power generation and the single largest source of both electric-generating capacity and electricity generation. CCGT plants use both a natural gas and a steam turbine.
The Grudziadz power project is a 560MW gas-fired combined cycle gas turbine (CCGT) power plant under development in the Kujawy-Pomorskie province, Poland. CCGT Grudziądz, a special purpose vehicle (SPV) entirely owned by Polish electricity supplier Energa Group, is responsible for the development of the power generation facility.
Fig. 8, Fig. 9 illustrate the energy flows within the CCGT unit and points out the different power and heat outputs as well as the losses in the different components. Fig. 8 shows the operation status of the selected CCGT unit for the DbBp case. The electricity production (628 MW) is the same as in the Agg case. This results in the same
Output from the U.S. CCGT fleet will likely rise from the 1,326,278 gigawatthours (GWh) it generated in 2021, which was 32% of total electricity generation last year. Shares of coal-fired generation (22%) ranked second, and nuclear sources (19%) ranked third in terms of electric-generating capacity and electricity generation in 2021.

The latest CCGTs (H-frame technology) are around 56% efficient (HHV). These units have a 3-10% efficiency advantage over existing CCGTs. Compare for example a 56% efficient new plant with a 52% efficient CCGT from the last wave of build in the late 2000s. The 4% efficiency advantage translates into an approximately 3 £/MWh increase
