Abstract
Electricity came to Nigeria (in 1896)15 years after it got to England. Despite its long history in Nigeria, electricitygeneration is still at its low ebb with power outages being the order of the day.Power generation is a product of reservoir operation;hence, the understanding of the interactions between them is crucial to energy supply. This study examines the interactions between electricity generation and reservoir elements in Jebba dam, Nigeria. Monthly data were collected on 11 reservoir elements and on monthly electricity generation from (1989-1999). Factor-multiple regression and factor-stepwise regression methods were adopted in the interpretation of the relationships between power generation and reservoir elements. A total of 12 factor analytical procedures were carried out, this representone operation per month. This allowed the exhibition of the relationships on monthly basis. The factor analysis reduced the monthly variables to between 3 to 4 orthogonal factors. All the factors were important to the explanation of the variance with the percentages of explanations ranging between 79 and 92%. The result of the regression analyses showed that reservoir elements were strong predictors of power generation in all the months with the exception of April. The percentage explanation for factor multiple regression range from 13 to 98%; while that of factor stepwise regression ranges from 57.8% to 95.7% , with the exception of April when all the variables entered the equation. Twenty one reduce - rank (eqs. 5-26)power generation models were developed for predicting power generation in Jebba.
