The Yixing Upper Reservoir is located atop Mount Tongguan which peaks at 530 m above sea level. During periods of low energy demand, such as at night, water is pumped from Huiwu Lower Reservoir up to the upper reservoir. When energy demand is high, the water is released back down to the lower reservoir but the pump turbines that pumped the water up now reverse mode and serve as generators to produce electricity. Water from the nearby Huangtong River can also be pumped into the lower reservoir to augment storage. The process is repeated as necessary and the plant serves as a peaking power plant.
