The present status of R & D on solar thermal electric power pilot plants in the world is summarized and especially the 1 MW pilot plants at Nio, Kagawa prefecture are reported in detail.
Economy, energy analysis and site selection for solar thermal electric power system in Japan are discussed. The capital cost, especially of collector is high at the moment. In future, the cost will be reduced from one by five to one by eight. The results of energy analysis indicated that the energy inputs for solar thermal electric power system is recovered from 15 to 24 years.
