A combined cycle gas plant is a type of power generation facility that uses both gas and steam turbines to produce electricity. It operates by burning natural gas to power a gas turbine, which generates electricity. The hot exhaust gases from this process are then used to heat water, creating steam that drives a steam turbine for additional electricity generation. This dual process increases the overall efficiency of the plant, often exceeding 60%, compared to traditional power plants. Combined cycle plants are considered more environmentally friendly because they emit less carbon dioxide and other pollutants, making them a popular choice for energy production in many regions.
