A Combined Cycle Power Plant (CCPP) is an efficient electricity generation facility that uses both gas and steam turbines to produce power. It operates by first burning natural gas in a gas turbine, which generates electricity. The hot exhaust gases from this process are then used to heat water in a steam generator, producing steam that drives a steam turbine for additional electricity generation. This dual process allows CCPPs to achieve higher efficiency compared to traditional power plants, as they make use of the waste heat that would otherwise be lost. By utilizing both gas turbines and steam turbines, these plants can convert more of the fuel's energy into electricity, reducing fuel consumption and emissions.
