A Combined Cycle power plant is an efficient energy generation system that uses both gas and steam turbines to produce electricity. In this setup, natural gas is burned in a gas turbine, generating electricity and producing hot exhaust gases. These gases are then used to heat water in a steam generator, creating steam that drives a steam turbine for additional electricity production. This dual process allows Combined Cycle plants to achieve higher efficiency compared to traditional power plants. By utilizing the waste heat from the gas turbine, they can convert more of the fuel's energy into electricity, reducing fuel consumption and lowering greenhouse gas emissions.
