The Harvey logistic model is used to predict the demand and supply of electricity in the country from 2005 to 2026. From the results obtained, the demand and supply of electricity show mixture of spikes because of mean reverse behavior about the mean values and the demand outweighed the supply. The consequence of this is that there is vast market prosperity for investors in the power sector in Nigeria. It is estimated that about 317.5 billion US dollars business opportunities are available to new independent power stations in Nigeria.
