Abstract
National power generation mix composition is based on the ranking (merit-order) of the various means of production from their marginal cost of electricity generation. Thus, significant reserves of hydrocarbons in oil-producing countries favoured the abusive use of oil or natural gas in the electricity mix. The purpose of this research is to analyze the power generation mix of these countries by constructing an optimal electricity mix based on the rational use (from an economic point of view) of various electricity production means. In this work, we assess the current and future situation of electricity production in Saudi Arabia, Egypt and Iran, thanks to linear, dynamic and statistical modeling efforts. Thereafter, we will conduct sensitivity analysis to measure the optimality and efficiency of electricity generation by taking into account the integration of alternative non-fossil-fuel based resources.
