What does the term combined cycle generation refer to?

The term combined cycle generation specifically refers to the utilization of two processes to enhance efficiency in electricity generation, commonly involving a gas turbine and a steam turbine. In this approach, the gas turbine generates electricity while producing hot exhaust gases that are then used to generate steam for the steam turbine. This dual generation process maximizes energy output from the fuel used, hence the rationale behind calling it "combined cycle."

This method is particularly advantageous as it significantly increases fuel efficiency compared to conventional power generation methods, allowing for more energy to be produced from the same amount of fuel. By capturing and utilizing the waste heat from one generation method to power another, combined cycle generation exemplifies an efficient and effective strategy for meeting electricity demand while reducing greenhouse gas emissions.
