This paper examined the effect of power supply and the performances of Small and Medium Scale Enterprises (SMEs). In doing this, the paper used durations of public power supply, bills paid for public power and cost paid for private power supply as measures of power supply on the performances index of the SMEs in Port Harcourt. The performance indexes are employed in the models as the dependent variables while the power supply indexes are the explanatory variables. The data were sourced primarily through a well-structured questionnaire and the samples determined by the Cochran sampling techniques. The data were analyzed with the Qualitative Respond Model. It was revealed that a lower duration of public power supply significantly reduces the profitability, productivity and revenue, as well as the storage of products of the SMSEs, examined. Hence, the study recommended among others that there is a need to allocate more electric power to the industrial area of Rivers state- Port Harcourt, especially in the day light to encourage productivity, profitability and employment generation in the state.
