The power station has an installed capacity of 1,836 megawatts (2,462,000 hp) utilizing 6 reversible Francis turbines.

Situated on the Daxi Creek, the Tianhuangping Dam creates the power station's lower reservoir.

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 882 metres (2,894 ft) long and 7 metres (23 ft) diameter penstocks down towards the power station which is above the lower reservoir.

After power is produced, the water is discharged back into the lower reservoir and the entire process can repeat.
