This paper presents the development of software for exergy analysis of gas turbine. The turbine plant consists of an air compressor, combustion chamber and turbine unit. In the development of the software, flowcharts and algorithm were developed to aid the coding of the software. Visual basic.net (6.0) programming tool was used as the programming language in coding the software. Data was collected from the external operator log sheet and panel operator log sheet of the gas turbine unit, power plant and utilities department of Warri Refinery and Petrochemical Company, Ekpan-Warri, Nigeria. An analysis was carried out using manual computation and subsequently the developed software was used to perform same analysis. Several verification tests carried out using the developed software showed that the software result is consistently close to 100% accuracy. The results obtained for the combustion and turbine unit of the plant indicates that the combustion chamber has the highest exergy efficiency (94.20%) while the highest exergy losses (13.18%) occurred at the turbine unit.
