AbstractThe solar power satellite (SPS) is an alternative power generation technology for the future. The authors elucidate the multiple aspects of the SPS system through common evaluation methods and an input-output database. In a previous paper, we confirmed that the SPS system has outstanding features in terms of CO2 emission, energy payback time (EPT), and energy profit ratio (EPR). In this paper, the authors focus on the economic aspects of the SPS system. The unit cost for construction and power generation from the SPS system are calculated and compared with those from other power generation technologies. The results show that the unit cost for construction is much higher than that of typical power generation systems and that the unit cost for power generation is almost the same as that for a renewable energy generation system, and a little higher than that of typical power generation system. The SPS system is superior in terms of CO2 emission and the energy indicators, as evident from our previous results. However, the higher cost of construction, operation, and maintenance could be recognized as the social cost of introducing the future technology.
