According to the data released by “Republic of Turkey-the Ministry of Energy and Natural Resources”, by the end of July 2017, 34% of the electricity of Turkey was produced from natural gas. As it is compared to the other resources such as coal 31% , hydraulic power 24% , wind 6% , geothermal energy 2% and from other sources 3% , natural gas still occupies the highest place in electricity production. The efficiency of the natural gas-fired power plants should be raised while the harmful effects of the exhaust gas emissions should be decreased. In this study, a natural gasfired gas turbine power plant that produces electricity in a private factory in the city of Çorum-Turkey was analysed at increasing environment temperatures of -2.7 °C to 7.5 °C based on the exergy destruction. The gas turbine data related to the operating conditions was provided by the private company. A computer code was improved with EES Engineering Equation Solver software to perform the exergy destruction analyses of the elements of the gas turbine cycle such as compressor, combustion chamber, turbine, boiler and economizer. At increasing environment temperatures of between -2.7 ° C and 7.5 ° C, it was found that the exergy destructions of the compressor, turbine, combustion chamber, boiler and economizer decreased. The maximum exergy destruction happened in the boiler and the minimum one happened in the combustion chamber.
