Combined Cycle Gas Turbines (CCGT)are a form of highly efficient energy generation technology that combines a gas-fired turbine with a steam turbine.
The design uses a gas turbine to create electricity and then captures the resulting waste heat to create steam, which in turn drives a steam turbine significantly increasing the system's power output without any increase in fuel.
The technology is typically powered using natural gas, but it can also be fueled using coal, biomass and even solar power as part of solar combined cycle plants.
