Abstract
In the current conditions of the world, preserving energy and creating sustainable sources has double importance. Therefore, it is necessary for the governments to move towards the use of sustainable energy in order to preserve resources and energy as well as generate income. The current research was conducted with the aim of producing sustainable energy using the hydroelectric method and providing an adaptable economic model for Mashhad Water and Wastewater Company. To ensure that the results are generalizable to any condition, location, and time, the calculations were arranged in such a way that if the required specifications for generating electricity through hydropower—based on technical principles and formulas from reliable scientific references—are considered as primary input data, the secondary data will show the amount of electricity generated and the resulting revenue based on the electricity purchase tariff.  Finally, the decision maker or investor, by calculating the amount of fixed and annual variable costs for the implementation of such a project and entering it into the necessary formulas, can calculate economic indicators such as the cost price of each kilowatt hour and the internal rate of return. Investment return period (IRR), net present value (NPV) of the project to decide whether or not to invest and to make a decision with their help. The results showed that in the studied sample with a flow rate of 0.075 m2/s and a height of 8 m, the amount of electricity produced is 30,077 kw/hr/year with a cost price of 79,000 Rials, which means that the project is not economical with the values ​​of this sample.
