'''Dul Hasti''' is a 390 MW [[Hydroelectricity|hydroelectric power plant]] in [[Kishtwar]] district of [[Jammu and Kashmir (union territory)|Jammu and Kashmir]], [[India]] built by [[NHPC]]. The power plant is a [[run-of-the-river]] type on the [[Chenab River]], in the [[Kishtwar District|Kishtwar region]], a rugged, mountainous section of the Himalayas, and several hundred kilometers from larger cities. It consists of a {{Convert|70|m|ft|abbr=on}} tall gravity dam which diverts water through a {{Convert|9.5|km|mi|abbr=on}} 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.<ref>{{cite web |title=Dul Hasti dam and Hydroelectric Power Project |url=http://www.tractebel-engineering-gdfsuez.com/reference/dul-hasti-dam-and-hydroelectric-power-project/ |publisher=Tractebel |accessdate=15 June 2013 |url-status=dead |archiveurl=https://web.archive.org/web/20121125130830/http://www.tractebel-engineering-gdfsuez.com/reference/dul-hasti-dam-and-hydroelectric-power-project/ |archivedate=25 November 2012 |df=dmy }}</ref>
==Design==
The Dul Hasti Hydro-Electric Project (HEP) involves a dam and a tunnel ending in a power plant at a bend in the Chenab River in the vicinity of [[Kishtwar]]. The dam is located at the village of Dul and the power plant at the village of Hasti, giving the name "Dul Hasti" to the project. The drop in the elevation between Dul and Hasti gives a [[hydraulic head]] of {{convert|200|m}} for power generation.

The Dam is 65 m high and 186 m long.<ref name="NHPC 2021"/> It is equipped with low-level gated spillways which can be used to flush [[silt]] load.<ref name="Big Brother">[https://kashmirlife.net/542420415-54242/ The Big Brother], Kashmir Life, 23 June 2012.</ref><ref>[https://powermin.gov.in/sites/default/files/uploads/ar06_07.pdf Annual Report 2006–07], Ministry of Power, 2007, p. 7.</ref>{{efn|The elimination of low-level spillways at the earlier [[Salal Dam]] has caused silt to build up, damaging the sustainability of the that project.

==Background==
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 over 2000 Million Units of electricity per year.{{sfnp|Dar, Power Projects in Jammu & Kashmir|2012|p=22}}<ref name="NHPC 2010">{{cite web |title=Welcome to Dulhasti Power Station |publisher=NHPC Limited |url=http://www.nhpcindia.com/Projects/english/Scripts/Prj_Introduction.aspx?vid%3D16 |url-status=dead |archiveurl=https://web.archive.org/web/20101127181202/http://nhpcindia.com/Projects/english/Scripts/Prj_Introduction.aspx?vid=16 |archivedate=27 November 2010}}</ref><ref name="NHPC 2021">{{cite web | title=Dulhasti |publisher=NHPC Limited |url=http://www.nhpcindia.com/Default.aspx?id=186&lg=eng&CatId=1&ProjectId=21 |access-date=6 June 2021}}</ref>

===Contracting and design===
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.
