Abstract
We have done research for the use for the electricity obtained by small scale hydropower for the Kuno river valley in Odawara-shi, Kanagawa in Japan, and for promoting city region activation. In order to promote activation of the area by the local supply and local consumption of the energy using small scale hydropower, it turned out that formation of a regional vitalization environmental platform is important. As the method of research, the program management by the P2M method was used. This paper explains the P2M method , the probabilistic assessment and the regional vitalization environmental platform of small scale hydropower.
