Abstract: Data ontime between complete power outages, Time between Failure (TBF) in Uyo wereconsidered. Trend test and serial correlation test were conducted graphicallyfor the data. The tests proved that the data were identically and independentlydistributed (iid). Summary statistics of the data showed that complete poweroutage occurred 416 times between the year 2014 and 2018. The maximumlikelihood estimation method was used to estimate the parameters of Weibull2-parameter, Normal, Lognormal 2-parameter and exponential distributions. Thevalues of Kolmogorov-Smirnov, Anderson Darling and Chi-Square statistics wereused to determine the best fit distributions. A model for thecomputation of reliability of electric power was then proposed.
