Effect of collector efficiency on levelized electricity cost of 200 MW solar chimney power plant in India

This paper presents an economic analysis of solar chimney power plant (SCPP) of 200 MW capacity in India by taking fifteen different sets of dimensions of chimney height and collector diameter, five sets each corresponding to collector efficiency of 33%, 50% and 65%. Quantity of different materials required and capital cost for construction of 200 MW solar chimney power plant is estimated. Based on capital cost, operation cost and maintenance cost, levelized electricity cost (LEC) for SCPP is calculated first for five sets corresponding to collector efficiency of 33% and calculations have been demonstrated. Calculations are repeated for collector efficiency values of 50% and 65%. Further, capital cost and LEC for different values of collector efficiency were compared.
