dc.description.abstractA reliable electrical power supply is non-negotiable for national growth and development, as electricity is needed in virtually every sector of production and commercial activities. The Shiroro hydroelectric power station (SHEPS) commissioned in 1990 comprises four units of turbo-alternators made of Francis turbine rated at 150 MW each. In this paper, an EXCEL-VBA script was used to extract a contiguous set of up and down times which were used to compute ‘time-between-failures’ (TBF). The failure events and failure rate of each unit were estimated using the power generation data of the station from the year 2008 to 2015. A structured database was organized for accurate analysis. Unit 3 was found to have the longest TBF with a value of 46 days, while the least was found in unit 1 with a value of 17 days. The Reliability value of each unit was also computed and unit 3 was found to be the only unit having a value up to 70%. SHEPS was found to still be in its productive age and possesses a tendency of still generating close to the rated value if properly refurbished.
