Dul Hasti is a 390 MW hydroelectric power plant in Kishtwar district of Jammu and Kashmir, India built by NHPC. The power plant is a run-of-the-river type on Chandra River, a tributary of Chenab River, in the Kishtwar region, a rugged, mountainous section of the Himalayas, and several hundred kilometers from larger cities. It consists of a 70 m (230 ft) tall gravity dam which diverts water through a 9.5 km (5.9 mi) long headrace tunnel to the power station which discharges back into the Chenab. The project provides peaking power to the Northern Grid with beneficiary states being Jammu and Kashmir, Punjab, Haryana, Uttar Pradesh, Uttarakhand, Rajasthan, Delhi and Union Territory of Chandigarh. It was constructed between 1985 and 2007.

Begun in 1985, the Dulhasti Power project, set in the northern Indian provinces of Jammu and Kashmir, represents an example of a disaster in project cost estimation and delivery. As initially conceived, the project's cost was estimated at 1.6 billion rupees (about $50 million). By the time the contract was let, the cost estimate had risen to 4.5 billion rupees and later successively to 8, 11, 16, and 24 billion rupees (nearly $750 million). The project became operational on 7 April 2007 and has been generating 1907 Million Units of electricity in a 90% Dependable year
The contract for the power generation project was first awarded to a French consortium at a price of $50 million, who almost immediately asked for an upward price revision. The site was intended to capitalize on the proximity to a large river systems capable of providing the water capacity needed to run a hydroelectric plant of Dulhasti's dimensions. Unfortunately, the site selected for the project came with some serious drawbacks as well. First, it was sited in the disputed border region between Pakistan and India. Jammu and Kashmir have been the epicenter of numerous and serious clashes between separatist forces demanding independence and Indian army . Constructing such an obvious target as a power plant in the disputed area was sure to provoke reaction by militant groups, using it as their chief means of opposition. Thus, the additional costs of providing security to the site quickly became prohibitively expensive. A second problem concerns the sheer geographical challenge of creating a large plant in a region almost totally devoid of supporting infrastructure, including an adequate logistics network (roads and rail lines). Building the plant in the foothills of the Himalayas may be scenic, but it is not cost effective, particularly as almost all supplies had to be brought in with air transportation, at exorbitant costs. All raw materials, including cement, wood, stone, and steel, had to be hauled by helicopter for miles over snowbound areas.
The Chenab River (Punjabi: ਚਨਾਬ cenab; Urdu: چناب), known traditionally as the Chandrabhaga River (Sanskrit: चन्द्रभागा), is a major river that flows in India and Pakistan, and is one of the 5 major rivers of the Punjab region. It rises in the upper Himalayas in the Lahaul and Spiti district of Himachal Pradesh state, India, and flows through the Kishtwar, Doda, Ramban, Reasi and Jammu districts of Jammu region in Indian state of Jammu and Kashmir into the plains of Punjab, Pakistan, before flowing into the Indus River near the city of Uch Sharif. The waters of the Chenab were allocated to Pakistan under the terms of the Indus Waters Treaty.The river is formed by the confluence of two rivers, Chandra and Bhaga, at Tandi, 8 km southwest of Kyelang, in the Lahaul and Spiti district in the Indian state of Himachal Pradesh. The Bhaga river originates from Surya taal lake, which is situated a few kilometers east of the Bara-lacha la pass in the in Himachal Pradesh. The Chandra river originates from glaciers east of the same pass. This pass also acts as a water-divide between these two rivers. The Chandra river transverses 115 km (71 mi) before the confluence. The Bhaga river transverses through narrow gorges a distance of 60 km (37 mi) before the confluence at Tandi.List of dams and reservoirs in India
This page shows the state-wise list of dams and reservoirs in India. It also includes . Nearly 3200 major / medium dams and barrages had been constructed in India by the year 2012.List of run-of-the-river hydroelectric power stations
The following page lists hydroelectric power stations that generate power using the run-of-the-river method. This list includes most power stations that are larger than 100 MW in maximum net capacity, which are currently operational or under construction. Those power stations that are smaller than 100 MW, and those that are only at a planning/proposal stage may be found in regional lists, are listed at the end of the page.Ratle Hydroelectric Plant
The Ratle Hydroelectric Plant is a run-of-the-river hydroelectric power station currently under construction on the Chenab River, downstream of the village of Ratle, near Drabshalla in Kishtwar district of the Indian state of Jammu and Kashmir. The project includes a 133 m (436 ft) tall gravity dam and two power stations adjacent to one another. Water from the dam will be diverted through four intake tunnels about 400 m (0.25 mi) southwest to the power stations. The main power station will contain four 205 MW Francis turbines and the auxiliary power station will contain one 30 MW Francis turbine. The installed capacity of both power stations will be 850 MW. On 25 June 2013, Prime Minister Manmohan Singh laid the foundation stone for the dam. Pakistan has frequently alleged that it violates the Indus Water Treaty.
