What is Combined Cycle Power?
Using energy twice, combined cycle power plants are highly efficient and make more eco-friendly use of fuel. The term “combined cycle” refers to the combining of two thermodynamic cycles to generate power. A combined cycle power plant uses a gas and steam turbine together to produce up to 50% 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. Combined cycle plants are usually fueled by natural gas, although fuel oil, synthesis gas or other distillate fuels can be used.
Why Combined Cycle?
Higher efficiency. Combined cycle plants produce higher power outputs at higher efficiences and with lower emissions. Because of that, these types of power plants are being installed in increasing numbers around the world, especially in areas were there is access to substantial quantities of natural gas.
Customer Value. Customer benefits to combined cycle power includes higher efficiency, higher flexibilty and availabilty, low life cycle costs, lower fuel consumption and lower operating costs.
Environmental Value. Compared to the average power generating facilities worldwide, combined cycle power reduces carbon dioxide emissions per kilowatt hour.
