“…Bori et al [9] look at the techno-economic approach to readily assess the profitability or otherwise of combined cycle power plants (CCPPs) for increased electricity production in Nigeria. The research also proposes upgrading existing gas-fired power plants in the Nigeria into combined cycle power plants for improved electricity supply.…”

Aim: The aim of this research is to evaluate the performance of the Olorunsogo gas-fired power plant phase 1, examines the reason(s) for not operating at full capacity, and proffers possible solution(s). Study of the Design: The power plant comprises of eight (8) numbers of 42MW unit gas turbine capable of evacuating 277MW. Methodology: To obtain electrical parameters from the gas turbine, a mathematical model for pressure using a simple open-cycle gas turbine was developed. The pressure was further converted to energy using principles of kinetic theory of gases. Hence, the efficiency and other performance indicators were calculated. Results: The study revealed an average operating capacity of 31.28MW. The average efficiency of the power plant in the period under review was 50.88%, as compared to the international standard practice of 65% and above. The average load factor and capacity factor was 11.25% and 11.54% respectively as compared to international standard practice of 50-80%, while the average reliability was 55.79%, as compared to international standard practice of 95%. Conclusion: The study further reveals that wastage of gas, downtime, and inadequate gas supply are the major factors against the full capacity operation of the power plant. The proffered possible solutions articulated in this study if implemented, will optimize the power plant's full-capacity operation.
