, the Tianhuangping Dam creates the power station's lower reservoir. The concrete face rock-fill
dam is high and long. The dam creates a reservoir that can store of water and contains an uncontrolled side-weir spillway that can discharge a design level of .
Upper reservoir
From the lower reservoir, water is pumped up into the upper reservoir which has a normal storage capacity of . The upper reservoir is artificial and cut into the mountain and created with the assistance of four saddle dams. When power is being generated, the water leaves the reservoir and falls through two long and diameter

s down towards the power station which is above the lower reservoir. Before reaching the reversible turbines, the water branches off into six branch pipes.
Power station
The six branch pipes feed water into the six turbines. Each reversible Francis turbine has a installed capacity and maximum capacity. The turbines and generators are stored in an
underground power house measuring long, wide and high. After power is produced, the water is discharged back into the lower reservoir and the entire process can repeat.
