Economic Analysis of Solar Trough, Tower and Dish Power Plants

Abstract:

Solar thermal power system can be classified to three typical kinds, parabolic trough, tower and dish system. Trough and tower systems have been commercial operated in last few years. Solar dish power plant is also in demonstrational phase. But how to choose a fit technology road is also a different challenge. In the paper, three solar thermal power plants are analyzed, located in same location in Gansu province. Three power plants electricity loads and total investments in same capacity and collector area are calculated to analyze the economic characters by Levelised Electricity Cost (LEC) method. Finally, three power plants LEC distributions are also analyzed in the conditions of different loan interests and life span. The results indicate that the minimum LEC is tower in current market conditions. The research results can be used to support technology choice, and design optimization in specific climate condition.
