The Shimokotori Dam is a rock-fill dam on the Shimokotori River about 15 km (9.3 mi) west of Hida in Gifu Prefecture, Japan. The primary purpose of the dam is hydroelectric power generation and water from its reservoir is diverted via a 8.5 km (5.3 mi) long headrace tunnel to a 142 MW power station northeast of the dam. The power station discharges the water into the Jinzū River. Construction on the dam began in 1970 and it was completed in 1973. The power station went operational in May 1973 and is owned by Kansai Electric Power Company. [1] [2]
Hida is a city located in Gifu, Japan. As of 1 December 2017, the city had an estimated population of 24,726, and a population density of 31 persons per km2, in 8,905 households. The total area of the city was 792.53 square kilometres (306.00 sq mi). The official kanji for the city is actually 飛驒, which uses the old (kyūjitai) rendering of the 騨 character. However, the 驒 character is not included on the official list of usable characters, so the 騨 character is often used outside of the city.
Gifu Prefecture is a prefecture in the Chūbu region of central Japan. Its capital is the city of Gifu.
The Jinzū River is a river that flows from Gifu Prefecture to Toyama Prefecture in Japan. It is called Miya River in Gifu. It is 120 km (75 mi) in length and has a watershed of 2,720 km2 (1,050 sq mi).
The Kurobe Dam (黒部ダム) or Kuroyon Dam (黒四ダム), is a variable-radius arch dam on the Kurobe River in Toyama Prefecture, Japan. It supports the 335 MW Kurobe No. 4 Hydropower Plant and is owned by Kansai Electric Power Company. At 186 metres (610 ft) in height, it is the tallest dam in Japan. It was constructed between 1956 and 1963 at a cost of ¥51.3 billion yen. The project was a difficult engineering feat for the rapidly growing post–World War II Japan, and claimed the lives of 171 people.
The Krasnoyarsk Dam is a 124-metre (407 ft) high concrete gravity dam located on the Yenisey River about 30 kilometres (19 mi) upstream from Krasnoyarsk in Divnogorsk, Russia. It was constructed from 1956 to 1972, and it supplies about 6,000 MW of power, mostly used to supply the KrAZ. Both power and aluminum plants are controlled by the RUSAL company.
The Tokuyama Dam is an embankment dam near Ibigawa, Ibi District, Gifu Prefecture in Japan. The dam was completed in 2008 and will support a 153 MW hydroelectric power station that is expected to be fully operational in 2015. Currently, Unit 1 at 23 MW was commissioned in May 2014. The dam was originally intended to withhold the upper reservoir of a 400 MW pumped-storage power station until a design change in 2004. The dam is also intended for flood control and water supply. It is the largest dam by structural volume in Japan and withholds the country's largest reservoir by volume as well.
Miboro Dam is a dam on the Shō River in Shirakawa, in Gifu Prefecture Japan. It supports a 256 MW hydroelectric power station. Of the nine dams on the Shō River, it is the furthest upstream.
Sakaigawa Dam is a dam in Nanto, Toyama Prefecture and Shirakawa, Gifu Prefecture, Japan. It is named for the Sakaigawa River, upon which it is built. The dam has an associated 27 MW hydroelectric power station about 2.9 km (1.8 mi) downstream. It was commissioned in June 1993.
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).
