Abstract (2. Language): 
Electricity generation of any nation serves as an engine that drives an economy of such nation. Sufficient power supply is very crucial for industrial development and economic growth of any nation. Recent studies show that most of the hydro-electric generating stations in Nigeria are operating below their installed capacity which is as a result of non-overhauling of turbines installed at the hydro power plants. This study is aimed at providing an operational efficiency analysis of Shiroro hydro-electric power plant for the reviewed period (2004-2014).The model equations were formulated based on some performance parameters used in power plant analysis. The considered criteria were plant availability factor, capacity factor and the overall efficiency of the plant. Also a Graphical User Interface (GUI) was developed for evaluating plant data on annually basis depending on the interest of the users and comparing the overall efficiencies of the plant graphically. The study reveals that 50.1% to 88.3% MW of the installed capacity was available in the period. The percentage of shortfall of energy generated in the period ranged from 23.5% to 47.3% as against the acceptable value of 5–10%. The capacity factor of the plant is between 23.5% and 50.7% as against international best practice of 80%. The average availability of the plant for the period was about 75% as against industry best practice of 95%, while the overall efficiency of the plant ranges from 27.1% to 80.4%. Measures to improve the performance indices of the plant have been suggested such as training of operation and maintenance (O & M) personnel regularly, improvement in O& M practices, proper spare parts inventory and improvement in general housekeeping of the plant.
