ECONOMIC ANALYSIS OF SOLAR CHIMNEY POWER PLANTS IN NORTHWEST CHINA
Solar chimney power plant (SCPP) with a long life span is a promising large-scale solar thermal utilization technology. This paper performs economic analysis of the conventional solar chimney power plant (CSCPP) and the sloped solar chimney power plant (SSCPP) in Northwest China. Cash flows are influenced by many factors including the investment, the transportation cost, the payback period, the inflation rate and the sale price of solar electricity. The techno-economic analysis and comparison of CSCPP and SSCPP are performed taking Lanzhou City as a case study. The results show that initial investment of SSCPP is much smaller than that of CSCPP; and SSCPP is more cost-effective than CSCPP during the system life span. In addition, the electricity sale price per kWh decreases gradually with the system power increasing largely. The economic evaluation of building SCPPs in Northwest China is of high significance considering the local abundant solar radiation but under-developing economics.
