Abstract
In Japan, there is a technical barrier of micro hydropower (MHP) small hydropower (SHP) development, which is a lack of skilled about small and micro size technology in the Japanese market. Japanese industries have advanced technology for large-scale hydropower, such as dam facilities, big turbines and generators, electrical control systems. However, in case of small and microscale, there is insufficient capacity in making an accurate assessment of suitability at a local level. In this paper, we challenged to develop the compact hydropower plant package through the practical case study. In Japan, an unused rice-producing districts are increasing, because of the aging and depopulation community. This paper deals with a micro hydro power plant by using the irrigation water for generating power. The power generation project had been done at Oohito community, Miyazaki prefecture in Japan, collaborated with the local SHP development team: local company, university, agricultural association and Asian SHP networks (especially Indonesia and India).
