In the commercial sector, power demands peak in the summer daytime because of high space coolingdemands, and cogeneration plants are required to produce maximum power to meet their demands. However, gas turbinewith cogeneration plants have the disadvantage of decrease in maximum power output in the summer daytime, whichreduces the availability of gas turbine. In the present study, for a further understanding of the effect of the ambienttemperature and inlet air temperature on the performance of gas turbine, an analysis based on 24 hours data has beencarried out. The main objective is to determine the effect of variation in ambient air temperature on the gas turbineoutput and heat rate. The results shows that when ambient temperature increases, gas turbine output decreases. It wasalso found that when ambient temperature increases, heat rate increases. It was observed that the maximum output of30.73 MW is produced at 7.00 a.m. (early morning) when ambient temperature is recorded 24.2 0C, while the minimumoutput of 26.85 MW is produced at 15.00 p.m. (noon) when ambient temperature is recorded 36.7 0C. It was also noticedthat the overall gas turbine output variation was 4 MW corresponding to overall temperature variation of 13 0C.
