The economic performance of concentrated solar power industry in China

Studying the economic performance is of great significance to the policy improvement and investment decisions making of concentrated solar power (CSP) industry. This study developed a cost-benefit model to analyze the economic benefits of CSP industry, under the current technological level and policy system of China. The results showed that: Firstly, the huge initial costs resulted in that the investment of CSP industry had to bear a long capital recovery period, which might add the investment risks; meanwhile it was still economically feasible because of better expected benefits. Secondly, for CSP industry, the internal rate of return mainly varied from 8% to 12%, and the average levelized cost of energy was $0.148/kWh; the economic performance of CSP industry was attractive from the multiple dimensions analysis, and the benchmark feed-in-tariffs could provide effective support for the CSP industry development of China. Thirdly, adopting solar tower CSP technology was better choice to improve the economic benefits of CSP industry, compared with parabolic trough and linear Fresnel CSP technologies. Lastly, the direct normal irradiation, initial costs, annual electricity production and loans ratio had important impacts on the economic benefits of CSP industry, and should be paid more attention in investment decisions.
