Ĭonnecting the upper reservoir to the power station is an intake which feeds water into two 5.7 metres (19 ft) diameter head-race tunnels. The normal elevation for the upper reservoir is 2,406.5 m (7,895 ft) and the lower 1,905.4 metres (6,251 ft) which affords a gross maximum hydraulic head of 520 m (1,706 ft) and normal of 504 metres (1,654 ft). The upper dam's has a maximum discharge capacity of 203 m 3/s (7,169 cu ft/s) and the lower: 198.25 cubic metres per second (7,001 cu ft/s). Each of the dams are equipped with a chute staircase spillway. Its reservoir has a storage capacity of 6,874,709 m 3 (5,573 acre⋅ft) (of which 3,600,000 cubic metres (2,900 acre⋅ft) is active or usable) and a surface area of 141 km 2 (54 sq mi). It contains 2,300,000 cubic metres (3,000,000 cu yd) of fill and is 12 m (39 ft) wide at its crest and 360 metres (1,180 ft) wide at its base. The lower reservoir dam is the bigger of the two and is 102 m (335 ft) tall and 332 metres (1,089 ft) long. Its reservoir has a storage capacity of 4,344,220 cubic metres (3,521.92 acre⋅ft) (of which 3,500,000 m 3 (2,837 acre⋅ft) is active or usable) and a surface area of 141 square kilometres (54 sq mi). It contains 1,550,000 cubic metres (2,030,000 cu yd) of fill (structural volume) and is 12 metres (39 ft) wide at its crest and 280 m (919 ft) wide at its base. īoth the upper and lower reservoirs are created by concrete-face rock-fill dams on the Chalus River which has an average inflow of 67.1 cubic metres per second (2,370 cu ft/s). The pumping/generating process repeats as needed. Pumping occurs during low demand, cheap electricity, periods such as night and generating will occur during peak demand, expensive electricity, hours such as during the day. Water is either pumped from the lower to the upper reservoir to serve as stored energy or released from the upper to the lower reservoir to generate electricity. The power plant operates using a lower and upper reservoir along with a power plant connected to both. The first of four generators was commissioned in May 2013 and the remaining were operational by 1 September 2015. Both the upper and lower reservoir were complete and had finished impounding in January 2013. The project was 90 percent complete as of April 2012. In 20, contracts for the dams and power plant were awarded and construction continued. Construction would not commence again until 2001. Further designs for Phase I ( superstructures) were developed and construction continued until 1992 when a lack of funding halted the project once again. In 1983, Lahmeyer International was contracted to create designs for Phase II (underground excavation) which were completed in 1985, the same year construction on the dam's diversion tunnels began. The Albors Mountains study concluded in 1977 and geologic studies began in 1978 but were halted in 1979 due to the Iranian Revolution. In 1975, a feasibility report on the Siah Bisheh project was submitted to the Ministry of Energy. Several sites for dams were identified including Siah Bisheh as a potential place for a pumped-storage power plant. Ī site was first identified for the power plant in the 1970s when a study was carried out on the water resources of the Albors Mountains by the Belgian firm Traksionel.

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 remaining generators were commissioned by 1 September 2015.

It was delayed from 1992 until 2001 and the first generator went online in May 2013. Planning for the project began in the 1970s and construction began in 1985. 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). 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. The Siah Bisheh Pumped Storage Power Plant ( Persian: نیروگاه تلمبه ذخیرهای سیاهبیشه), 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.
