Abstract: Today among the various energies conspicuous, electric power is a significant source of industrial energy that is important for industries, agriculture and household use. Therefore, this article aims to study the trend of probable power generation in Iran, its state of consumption following Iran’s vision plan in the year 2025. Although, there are some studies on Iran’s electricity demands; the researchers studied on the relation between electricity consumption and GDP in a bi-variable assumption. Thus, this study focused on a multi-variable model to predict efficiently the electricity need for Iran 2025.
