A combined-cycle power plant uses both a gas and a steam turbine together to produce up to
50 percent more electricity from the same fuel than a traditional simple-cycle plant. The
waste heat from the gas turbine is routed to the nearby steam turbine, which generates
extra power.
If several power plants work together to meet the demand of the consumer then the system is
known as “Interconnected System”
The Combined Cycle Power Plant or combined cycle gas turbine, a gas turbine generator
generates electricity and waste heat is used to make steam to generate additional electricity
via a steam turbine. The gas turbine is one of the most efficient one for the conversion of gas
fuels to mechanical power or electricity. The use of distillate liquid fuels, usually diesel, is
also common as alternate fuels.
More recently, as simple cycle efficiencies have improved and as natural gas prices have
fallen, gas turbines have been more widely adopted for base load power generation,
especially in combined cycle mode, where waste heat is recovered in waste heat boilers, and
the steam used to produce additional electricity.
