Huizhou Pumped Storage Power Station

The Huizhou Pumped Storage Power Station is a pumped storage hydroelectric power station near Huizhou in Guangdong province, China. It contains 8 pump-generators that total a 2448 MW installed capacity. Initial units went online between 2007 and 2008, and the power station was complete on June 15, 2011.

The power station is supplied with water by an upper reservoir which is created by two dams. The main dam is a 56 m tall and 156 m long roller-compacted concrete (RCC) dam. The second, auxiliary, dam is 14 m high and 133 m long. Once water from the upper reservoir is transferred through the power station, which is located 420 m underground, and electricity produced, it discharges to a lower reservoir. This lower reservoir is created by a single 61 m tall 420 m tall RCC dam. The water can then be pumped by the generators back into the upper reservoir for reuse.
