Abstract

This study is solemnly concerned with the performance evaluation of the Omotosho gas Power plant over a period of four years. The station is made up of 8 units of 42MW Gas Turbine (GT) each. Data of necessary parameters such as average actual load, the install capacity of the station, hours of operation, energy generated, peak load, amount of gas consumed, the Net calorific value of gas, generator efficiency and available turbine unit was obtained and computed to measure the performance of the station between year 2014 to 2017. The results indicated that the average availability of the station varies from 45.02% to 89.18% which is against the recommended industrial practice of 95%. Also, the reliability of the station varies from 57.95% to 86.62% which is against the recommended 99.9% for best industrial practice. Likewise, the capacitor factor of the station varies from 16.29% to 49.98%, only the CF of 2016 which is 49.98% conform to the best industrial practice of 40-80% for the TP plant. Furthermore, the thermal efficiency of the station varies from 26.66% to 30.03% and the total efficiency varies from 26.66% to 29.43% which is against the recommended standard of 49% for thermal efficiency and 80% for overall efficiency. The findings revealed that the station performance is below the recommended standard, also this study gives an indices to evaluate gas power station in accordance with industrial practice. The findings of this research can be used to evaluate the performance of any gas station. This study, therefore, suggests that maintenance crew should maintain Omotosho power plant unit in accordance with the manufacturer’s specifications in order to increase the reliability of the station.
