The Guangdong Pumped Storage Power Station or Guangzhou Pumped Storage Power Station is a pumped-storage hydroelectric power station near Guangzhou, Guangdong Province, China. Power is generated by utilizing eight turbines, each with a 300 megawatts (400,000 hp) capacity, totalling the installed capacity to 2,400 megawatts (3,200,000 hp). The generated power is sold to China Light and Power customers in Hong Kong. The power station was constructed in two stages, the first four turbines were completed in 1994 and the second four in 2000.
Tanbara Dam is a rock-fill embankment dam on a Tone River tributary in Gunma Prefecture of Japan. It is located 14 kilometres (8.7 mi) north of Numata. It creates the upper reservoir for the 1,200 megawatts (1,600,000 hp) Tamahara Pumped Storage Power Station (玉原発電所). Construction began in 1973 and the dam was complete in 1981 while the power station was commissioned in 1986. It is 116 metres (381 ft) tall and withholds a reservoir with a storage capacity of 14,800,000 m3 (11,999 acre⋅ft). Of that capacity, 13,000,000 cubic metres (11,000 acre⋅ft) is active for power generation. The lower reservoir for the pumped-storage power station is created by the Fujiwara Dam, located 4 km (2 mi) to the northwest on another Tone River tributary. Power is generated during periods of high energy demand and pumping occurs during times when energy demand is low such as at night. The power station contains four 300 megawatts (400,000 hp) reversible Francis turbine pump-generators which serve to both pump water and generate electricity. The upper Tamahara Reservoir is at an elevation of 1,177 metres (3,862 ft) and the lower Fujiwara Reservoir is at 651 metres (2,136 ft) which affords the power station an effective hydraulic head of 518 metres (1,699 ft). When pumping, the pump-generators can move up to 210 cubic metres per second (7,400 cu ft/s) of water and when generating, they discharge up to 276 cubic metres per second (9,700 cu ft/s).
The Siah Bisheh Pumped Storage Power Plant, also spelled Siyāhbisheh and Siah Bishe, is located in the Alborz Mountain range near the village of Siah Bisheh and 48 km (30 mi) south of Chalus in Mazandaran Province, Iran. The power plant uses the pumped-storage hydroelectric method to generate electricity during periods of high energy demand, making it a peaking power plant, intended to fulfill peak electricity demand in Tehran 60 km (37 mi) to the south. When complete it will have an installed generating capacity of 1,040 megawatts (1,390,000 hp) and a pumping capacity of 940 megawatts (1,260,000 hp). Planning for the project began in the 1970s and construction began in 1985. It was delayed from 1992 until 2001 and the first generator went online in May 2013. The remaining generators were commissioned by 1 September 2015. The power plant is the first pumped-storage type in Iran and will also use the country's first concrete-face rock-fill dam – two of them.

The Bailianhe Pumped Storage Power Station is a pumped-storage hydroelectric power station located 58 kilometres (36 mi) east of Huanggang in Hubei Province, China. It was constructed between 2004 and 2010 and has a 1,200 megawatts (1,600,000 hp) installed capacity. The power station operates by shifting water between an upper and lower reservoir to generate electricity. For this project, only the upper reservoir had to be created as an existing reservoir, the Bailianhe Reservoir, was used as the lower. During periods of low energy demand, such as at night, water is pumped from Bailianhe 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. The process is repeated as necessary and the plant serves as a peaking power plant.
The Baoquan Pumped Storage Power Station is a pumped-storage hydroelectric power station located 34 kilometres (21 mi) northeast of Jiaozuo in Henan Province, China.

The power station operates by shifting water between an upper and lower reservoir to generate electricity.
The Entracque Power Plant, also known as The Upper Gesso Plant, is a pumped-storage hydroelectric power station located in Valle Gesso just south of Entracque, Italy. The power station contains pump-generators for two co-located but hydraulically separated power schemes; the Chiotas-Piastra Plant and Rovina-Piastra Plant. Both plants use separate upper reservoirs but use Lago della Piastra as their common lower reservoir. To produce power, water is released from the upper reservoirs to the power station located at the lower reservoir. The pump-generators re-fill the reservoirs and the process repeats as needed. The Chiotas' upper reservoir, Lago del Chiotas, is located much higher in the valley and larger than Rovina's Lago della Rovina which affords it the ability to produce more electricity. The installed capacity of Chiotas is 1,184 megawatts (1,588,000 hp) with a hydraulic head of 1,048 m (3,438 ft) while Rovina has an installed capacity of 133.67 megawatts (179,250 hp) and a head of 598 metres (1,962 ft). Construction on the plant began in 1962 and operations started in 1982. It is owned and operated by Enel.
The Heimifeng Pumped Storage Power Station is located at the hills of Heimifeng, Qiaoyi town, Wangcheng district, 25 kilometres (16 mi) north of Changsha in Hunan province, China. It was constructed between 2005 and 2009 with the generators being commissioned in 2009 and 2010. The station generates power by transferring water between an upper and lower reservoir. When energy demand is high, water from the upper reservoir is released and used to generate electricity before being discharged into the lower reservoir. During times of low demand, water from the lower reservoir is then pumped back up to replenish upper reservoir. This process allows the station to meet peak energy demand and it can go from standstill to operational in three minutes.
The Hohhot Pumped Storage Power Station, also known by Huhehaote, is located 20 kilometres (12 mi) north of Hohhot in Inner Mongolia, China. It uses the pumped-storage hydroelectric method to generate electricity. The plant has an installed capacity of 1,224 megawatts (1,641,000 hp).

The Imaichi Dam (今市ダム) is a concrete gravity dam on the Togawa River located 4 kilometres (2.5 mi) west of Nikkō in Tochigi Prefecture, Japan. The dam serves as the lower reservoir for the 1,050 megawatts (1,410,000 hp) Imaichi Pumped Storage Power Station, while the Kuriyama Dam forms the upper. It is owned by TEPCO and was constructed between 1979 and 1986. The reservoir can store 9,100,000 cubic metres (7,400 acre⋅ft) of water. Of that storage volume, 6,200,000 cubic metres (5,000 acre⋅ft) can be used for power generation.
The Minghu Dam (Chinese: 明湖水壩; pinyin: Mínghú Shuǐbà, renamed the Takuan Dam, is a concrete gravity dam on the Shuili River located 7 km north of Shuili Township in Nantou County, Taiwan.

The Matanoagawa Dam (俣野川ダム) is a concrete gravity dam on a tributary of the Hino River located 2.3 km (1 mi) south of Kōfu in Tottori Prefecture, Japan. Construction on the dam began in 1978 and it was complete in 1984. The primary purpose of the dam is hydroelectric generation and it creates the lower reservoir for the Matanoagawa Pumped Storage Power Station (俣野川発電所). It is 69.3 metres (227 ft) tall and creates a reservoir with a 7,940,000-cubic-metre (6,440 acre⋅ft) storage capacity. The power station is located on the southern bank of the reservoir and contains four 300 megawatts (400,000 hp) Francis pump-turbine-generators. The upper reservoir for the pumped-storage scheme is created by the Doyo Dam located 6 kilometres (3.7 mi) to the southeast in Okayama Prefecture. To generate power, water from the Doyo Dam is sent to the power station, used to generate electricity and then discharged into the Matanoagawa Reservoir. This occurs when energy demand is high and when it is low, water is pumped back up to the Doyo Dam as stored energy. The same pump-generators that pump the water to Doyo reverse and generate electricity when it is sent back down. The first generator was operational in 1992 and the last in 1996.

The plant generates an average of 1,650 gigawatt-hours (5,900 TJ) annually but of course consumes even more. Generally the efficiency of this energy storage method is around 70-80%. The plant is owned by Société Electrique de l'Our and RWE. Construction on an eleventh pump-generator began in 2010 and it is expected to be commissioned in 2013, which will bring the plant's installed capacity to 1,296 megawatts (1,738,000 hp).
The Xiangshuijian Pumped Storage Power Station is a pumped-storage hydroelectric power station located 29 kilometres (18 mi) southwest of Wuhu City in Sanshan District of Anhui Province, China.
