Economic (Cost-Benefit) Analysis of Power Generation from Commercial Reinforced Concrete Solar Chimney Power Plant Built in the Desert Regions of Iran

This paper expands a model different from existing models to analyze the cost and benefit of a reinforced concrete solar chimney power plant (RCSCPP) built in the desert regions of Iran. Based on the model and some assumptions for values of parameters, this paper calculates total net present value (TNPV) and the minimum electricity price in each phase by dividing the whole service period into four phases. The results showed that the minimum electricity price in the first phase is higher than the current market price of electricity, but the minimum prices in the other phases are far less than the current market price. The analysis indicated that huge advantages of the RCSCPP over coal-fired power plants could be embodied in phases 2–4. In addition, the sensitivity analysis performed in this paper discovered that TNPV is very sensitive to changes in the solar electricity price and inflation rate, but responds only slightly to changes in carbon credits price, income tax rate and interest rate of loans. Our analysis predicts that RCSCPPs have very good application prospect.
