After the Great East Japan Earthquake in 2011, imported fossil fuels, energy cost and greenhouse gas are increasing and then the energy self-sufficiency rate is declining. The government is now promoting the effective use of renewable energy. Since the small hydropower is a clean domestic origin energy resources, it is expected to spread as a stable base load power generation. In this paper, the concrete cases of micro hydropower generation system by using Pump as Turbine, having the advantages for less investment and easier maintenance, applied in irrigation dam and water works, are introduced.
