In assuring the energy supply of Turkey, hydroelectric energy plays one of the most important roles in plans formulated to realize equilibrium between energy production and consumption. Hydroelectric power plants on Murat River, a tributary of Euphrates, is a part of the development plan for energy production. Operation of four dams in cascade on Murat River are simulated by using program package HECResSim. For this purpose, ten scenarios are formulated to utilize the hydraulic potential of Murat River between the elevations of 870 m 1225 m. This study provides detailed financial analyses of scenarios and shows how HEC-ResSim program can be used in formulation of alternative scenarios. Electric energy storage requirement due to the rising demand for peaking power is creating a completely new market value, which is also increasing the attractiveness of pumped storage power plants. The results of the simulation performed in Scenario 10 in which two pumped storage power plants are considered have 15% higher internal rate of return value than the other scenarios with conventional turbines. Results demonstrate the increasing attractiveness of the cascade system with reversible pump turbines.
