This paper presents an economic viability of solar chimney power plant for 200 MW capacity, in Rajasthan India. Estimation of quantity of different materials required and capital cost for construction of 200 MW solar chimney power plant is done. Based on capital cost, operation cost and maintenance cost, levelized electricity cost for solar chimney power plant is calculated and compared with the other power plants based on conventional energy resources. Finally effect of interest rate, inflation rate and number of working hours of the plant on levelized electricity cost is analyzed.
