A natural gas-fired combined cycle (NGCC) power plant is currently the most efficient and least polluting technology among fossil fuel power plants. Compared to coal-fired units, state-of-the-art NGCCs can achieve higher efficiencies (> 60% LHV) and emit less CO 2 per MWh generated (~ 350 kg MWh − 1 ) ( IEA-ETSAP, 2010a,b ).

Simple cycle gas plants are a type of natural gas power plant which operate by propelling hot gas through a turbine, in order to generate electricity.They differ from combined cycle gas plants because their waste heat is not supplied to another external heat engine, so they are only used to meet peaking power needs on the electrical grid.These turbines …

The difference in conversion rates is because coal-fired generation plants in the United States are often older and less efficient than many natural gas-fired plants. In U.S. power plants, generating a kilowatthour of electricity from coal requires on average about one-third more energy than producing a kilowatthour from natural gas.
