The rapid growth in Jordan＇s electrical and water needs cannot be addressed by the current and planned supply sources. A combined electric power and water desalination plant is proposed and studied in detail. The plant is designed to cover all of Jordan＇s electrical and part of its water needs up to the year 2020. Sensitivity analysis of the plant＇s profitability under several financing and fuel price scenarios was performed. The results show that such a plant represents a good investment opportunity under a wide range of conditions.
