The Box-Jenkins modeling approach was employed after the series were transformed to ensure stationarity using the first differencing method. The empirical results showed that ARIMA (1, 1, 0) and ARIMA (0, 1, 1) models fitted the electricity generation and consumption adequately. The whiteness of the residuals from the model was verified using Ljung-Box methodology. The projections for both electricity generation and consumption for five years ahead were made 80% and 95% confidence limits.enElectricity generation, electricity consumption, Box-Jenkins modeling, Augmented Dickey-Fuller, Ljung-Box method, Confidence limitsArticle
