The Dul Hasti Dam (other spelling: Dulhasti Dam ) is located in the Indian Union Territory of Jammu and Kashmir in the Himalayas on Chandrabhaga , the upper reaches of the Chanab .
location
The dam is located in the village of Dul in the Kishtwar district , 7 km north-northeast of the district capital Kishtwar . The dam's hydroelectric power station ( ⊙ ) is located 20 km downstream near the village of Hasti . The 10 km long stretch of the river from the dam to the confluence of the Marau is largely drained due to the diversion of the water.
Data
The dam was built between 1985 and 2007. The main purpose of the dam is to generate electricity. The barrier structure is a 186 m long gravity dam . Its height above the foundation level is 65 m. The dam volume is 200,000 m³. The river is dammed over a length of seven kilometers. The reservoir has an effective storage capacity of 10,970 million m³ and a total storage space of 11,550 million m³. The flood relief is designed for 8000 m³ / s.
A 10.586 km long pressure tunnel ( head race tunnel ) leads from the reservoir to the underground power plant, which is not far from the left bank of the river. A 298 m long drainage tunnel ( tail race tunnel ) leads the water back to the river. The installed capacity is 390 MW (3 Francis turbines of 130 MW each). The power plant is mainly operated during peak loads . It feeds the electricity into the northern power grid of India, which in addition to Jammu and Kashmir also supplies the states of Punjab , Haryana , Uttar Pradesh , Uttarakhand and Rajasthan as well as the union territories of Delhi and Chandigarh . The average annual electricity generation is 1907 million kWh.
