Supplying all generated power to the power company! This is a power plant that has two types of generators: "synchronous generators" and "induction generators."
A water conveyance route of approximately 1.9 km has been established from the Tsuchida Shimosen headworks, which takes water from the Nagase River, to the power station. Utilizing a drop of about 43.03 m, two turbines are operated using a maximum of 3.75 m³/s of water taken from the irrigation water.

basic information
The maximum output of this power plant is approximately 990 kW from two water turbines, generating enough electricity for about 1,000 households for a year. The generated electricity is supplied in full to the power company. This power plant is unique in the country, featuring two types of generators: a fully-fledged "synchronous generator" and a simpler "induction generator." In an era where technological decline and the inheritance of technology are being discussed, it is widely open for the training of hydroelectric power engineers, contributing to the improvement of hydroelectric power in Japan and serving as a usable facility.
