Journal Article 2024 06 21 The increase in population, natural disasters, the growth of energy-intensive industries and power plant aging are among the most significant threats to energy security in Iran. A geographic feasibility assessment, along with technical and economic optimization, was conducted in this study to supply electricity to a population of 50,000 residents on the Makran coasts. Simultaneously, the excess electricity has been used to meet the energy requirements of a seawater desalination plant in this high-water scarcity area. To determine suitable locations based on available infrastructure, the Geographic Information System (GIS) was employed. Ultimately, the methods for primary power supply were identified using a HOMER-MATLAB based multi-criteria decision-making approach. The results indicate that the certain parts of Jask, Konarak, Chabahar, and Beris regions, have the capability to host hybrid renewable plants. Additionally, with less than 19 MW of renewable power connected to the national grid, the reliability of the power supply has increased by over 99%. The final excess electricity has been reduced to less than 6%, annual CO2 emissions have decreased by more than 30%, dependence on power transmission lines has decreased by over 40%, and energy costs are expected to decrease to less than $0.05/kWh. https://www.jemat.org/article_205959_66fbf55e25404846b3fa5b72498e9a61.pdf
