Tanbara Dam is a rock-fill embankment dam impounding the headwaters of the Hotchi River, 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 Rio Grande Project is a United States Bureau of Reclamation irrigation, hydroelectricity, flood control, and interbasin water transfer project serving the upper Rio Grande basin in the southwestern United States. The project irrigates 193,000 acres (780 km2) along the river in the states of New Mexico and Texas. Approximately 60 percent of this land is in New Mexico. Some water is also allotted to Mexico to irrigate some 25,000 acres (100 km2) on the south side of the river. The project was authorized in 1905, but its final features were not implemented until the early 1950s.
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.
