Abstract

The components of power system are generation, transmission, distribution and utilization of electrical energy. The importance of the generating aspect cannot be over emphasized because the inevitable being played by this component of power system. This paper evaluates and analyses the performance of Omotoso Power Plant from year 2008 to year 2012 based on performance indices such as thermal and overall efficiencies. The period of outages of the Plant was evaluated based on the data that were obtained from the outage log books. The evaluation was performed with the aid of simple mathematical equations and data collection. This showed that the average values for thermal efficiency and overall efficiency of the generating plant was calculated to be 28.39% and 29.12% respectively due to different factors such as: break down or failures, obsolete technology, instability of the national grid system, ageing of plant components and disruption of gas supply.
