The Siah Bisheh pumped storage power plant , also spelled Siah Bishe and Siyahbisheh , is a pumped storage power plant in the Elburs Mountains in Iran that went into operation between 2013 and 2015 . It is located near the town of Siah Bisheh and 48 km south of Chalus in Mazandaran Province . The power plant is used to generate electricity during periods of high energy demand ( peak load power plant ) in the capital Tehran , 60 km south . The installed generator output is 1040 MW and the pump output is 940 MW.

history

Planning for the project began in the 1970s and construction in 1985. It was delayed between 1992 and 2001 and by April 2012 was 90 percent complete. The upper and lower basins were dammed in 2013. The power plant will be the first pumped storage power plant in Iran and will also have the country's first CFR dams (both shut-off structures on the upper and lower basins).

Planning and operation

The power plant is operated with an upper basin and a lower basin, between which there is a power plant that either pumps water from the lower into the upper one, which is stored there, or water is drained from the upper into the lower basin to generate electricity. It pumping at night during times of low demand and cheap electricity and electricity is produced during the daytime during times of high demand and expensive electricity. This process is controlled as required.

The upper and lower basins are both formed by a CFR dam . The river Tschalus here has an average discharge of 67.1 m³ / s. The upper dam is 82.5 m high and 436 m long. It consists of 1.55 million m³ of bulk material and is 12 m wide at the dam crest and 280 m at the base. The storage space is 4,34422 million m³, of which 3.5 million m³ is usable space and a water surface of 141 hectares. The reservoir water level is 2406.5 m above sea level and the catchment area is 19.3 ha.

The lower dam is the larger of the two; it is 102 m high and 332 m long. It will consist of 2,300,000 m³ of bulk material, is 12 m wide at the dam crest and 360 m at the base. Its reservoir will have a storage volume of 6,874,709 m³ (of which 3,600,000 m³ are usable space) and a water surface of 141 ha. Both dams will be equipped with a flood relief with a discharge channel . The upper dam will have a maximum discharge capacity of 203 m³ / s and the lower one 198.25 m³ / s. The normal water level of the upper basin is 2406.5 m and that of the lower basin is 1905.4 m, which enables a hydraulic head of between 520.8 and 470.8 m (net 504 m).

Two tunnels with a diameter of 5.7 m extend from the upper reservoir. They are 2225 m (left) or 2185 m (right) long to the moated castle . From there it goes through 680 m long pressure tunnels to the power plant, which is located near the lower basin. Each pressure tunnel there divides again to supply the four Francis turbines and pump generators. The pump generators have a generator output of 260 MW and a pump output of 235 MW. The turbines each work with a flow rate of 65 m³ / s. The electricity generated is converted by transformers into a voltage of 400 kV. The water flows from the power station through two tunnels (197 m and 159 m long) into the lower basin. When pumping, the machines pump the water up through the same lines. Each pump delivers 50 m³ / s.

The total cost was estimated at the equivalent of US $ 380 million.
