Why a combined cycle power plant? The simple reason – efficiency. When compared to a traditional coal or gas fired plant (boiler or simple cycle combustion turbine), a combined cycle plant's overall efficiency can be 20 – 30% greater. This means that fuel use is 20 – 30% less and the fuel cost per megawatthour is 20 – 30% lower.
