The Tala power plant is a run-of-river power plant in the Chukha district , Bhutan , which dams the Raidak , a right (western) tributary of the Brahmaputra . It consists of a dam wall ( English Wangkha dam ) and an underground machine house, which is about 30 km downstream of the dam at Tabji . Approx. 3 km upstream from the dam of the power plant is the powerhouse of the power plant Chukha .
The agreement to build the power plant was signed on March 5, 1996 between Bhutan and India. The Tala Hydroelectric Project Authority (THPA) was established to carry out the project . The construction of the necessary infrastructure began in October 1997. The first machine in the power plant was put into operation on July 31, 2006. The power plant is owned by Druk Green Power Corporation (DGPC) and is also operated by DGPC.
Barrier structure
The barrier structure is a concrete gravity dam with a height of 92 m. The length of the top of the wall is 130 m. A tunnel (length 356 m, diameter 6.8 m) initially leads to three settling basins . From there, a 22 km long tunnel guides the water to the machine house.
Reservoir
With the maximum storage target of 1,362 m, the reservoir extends over an area of around 0.75 km² and holds 9.8 million m³ of water. The minimum storage target is 1,352 m.
power plant
The Tala power plant has six machines and an installed capacity of 1,020 MW . The average annual production is 4.865 billion kWh . The first machine was put into operation on July 31, 2006, the last on March 30, 2007.
The 6 Pelton turbines with vertical shaft and the associated generators were supplied by BHEL . The power plant's turbines have a maximum output of 170 MW each. The rated speed of the turbines is 375 / min. Two (or three) 440 kV double lines with a length of 140 km lead from the switchgear to the Indian border.
The fall height is 860 m. The maximum flow rate is 141 m³ / s for all turbines together.
Others
The total cost of the project was 41.258 billion BTN (approximately $ 800 million ). The construction was financed by India, which receives the electricity generated for it. Bhutan intends to build around 10,000 MW of hydropower plant capacity by 2020, the electricity from which is to be exported.
