Abstract
J-POWER is promoting development of small hydro power plant projects using potential hydro
power resources. One of these projects is “Konokitani hydro power plant” which uses potential head between the outlet of Konokitani mountain stream intake and existing Kuzuryu dam, maximum discharge is 3.22m3/s, normal effective head is 7.4m, and maximum output is 199kW. Since the hydro turbine installation site is submerged in the reservoir at higher water levels, a submersible turbine is adopted. This paper will introduce development and construction of Konokitani HPP in Japan.
