ものである。In such a hydroelectric power generation facility 10, as shown in FIG.
The electric power is obtained by rotating the turbine with the water falling in the pressure pipe 6 as in the case of the conventional general waterway type power generation facility 1 as shown in FIG. It is adjusted by controlling the opening degree of 14. In the conventional general power generation facility, since the river water is directly guided to the power plant 5 through the pipe 3, the amount of water supplied to the power plant 5 naturally depends on the flow rate of the river water. In the facility of the present embodiment, since the river water is guided to the underground water storage tank 12 and stored therein, and then the water stored in the underground water storage tank 12 is supplied to the power plant 5, for example, the power demand is The surplus water is stored in the underground water tank 12 in a small amount of winter or at night, and the stored water is used in the summer or daytime when there is a large amount of power demand, so that the amount of water supplied to the power plant 5 can be increased as long as there is stored water. It can be adjusted freely without depending on the flow rate of the river water, and the required amount of water to be supplied to the power plant 5 can always be secured.

By adjusting the opening degree of the water control gate 21 appropriately, the amount of inflow to the underground water storage tank 12 is adjusted, or while the river water is introduced into the underground water storage tank 12, a part thereof is bypassed by the bypass portion 3c of the pipe 3.
It is also possible to freely supply the power directly to the power plant 5 through. Therefore, for example, when the amount of water supplied to the power plant 5 is particularly large, it is possible to simultaneously supply the stored water from the underground water tank 12 and the direct supply from the river.
