Details of alternative sites examined
No shown on a toposheet
Initially three alternative dam axis were selected across the
river Chenab downstream of village Kirthai in consultation
with geologists from GSI. But a high storage dam at any of
these sites would have submerged Padder valley
comprising of some villages and agricultural & forest lands.
One more site was selected upstream of this valley, but the
storage available at any site above the valley was
comparatively less than that at any downstream site. In
order to finalize the dam axis, expert team comprising of
Engineering Geologists from GSI and Designers from CWC
visited the project site in May 1989. The experts during the
time of the visit observed that though a dam and power
house upstream of Padder valley at Gulabgarh would in
itself be a feasible project, it will not fully utilize the power
potential available in the reach. It was therefore suggested
that Dam at Gulabgarh can be constructed as Stage I of
the entire scheme and relatively lower pick up dam (100 m
high) can be located downstream of the valley. This would
avoid submergence of the Padder valley and would tap the
balance power potential.The comparative study was made
by taking into consideration all the alternatives and finally
it was decided to have a storage dam at Gulabgarh with
underground power house at Gulabgarh itself (Kirthai H.E.
Project Stage I) and a lower dam near Silpar or Kidur with
underground power house at Lidrary (Kirthai H.E. Project
Stage II)

1766 masl and consisting of 93 m long over flow section. The sluice spillway, with 5 bays fitted
with radial gates(9mx12.248m), with crest at El 1712.5 masl, has been designed to pass the
PMF of 9660 cumec. A power intake with invert level at El 1731.80 masl shall convey the
regulated discharge through 4 number, 6.4 m diameter, intake tunnels of varying length leading
to four desilting chambers (440mx19mx24.87m) which in turn are joined to four flushing
tunnels/ducts (3.6mx2.5m) to escape silt laden water into the river. Appropriate HRT manifold
shall be provided from which 10.5 m diameter 4.289 km long HRT, with invert level at the start
El 1725.00 masl, shall take off to convey 413.47 cumec discharge to 31.6 m diameter surge
shaft connected at its lower end to concrete lined steel liner pressure shafts (3 No,5.25m
diameter,827m long), each further bifurcating to unit penstocks to feed six number generating
units of 140 MW capacity each under a net rated head of 225.1 m and housed in an
underground power house of cavity size 187.5 m X 22 m X 49.7m on the left bank of the
Chenab. The discharge through draft tubes shall be led to the river through 11.25 m
diameter352.5m long circular tunnel with average outfall at El 1530 masl For dam toe
powerhouse a Power intake shall be provided in the dam block-9 to exploit the environmental
flow release of 99.71 cumec at a net head of 99.95 m at the dam toe power house. The water
from the powerhouse shall be conveyed through 51m longTRC. The reservoir FRL has been
fixed at El 1764 masl from the consideration of submergence alone. The Minimum Draw Down
Level (MDDL) has been estimated at 1750.75 m, from consideration of the live storage of 17
MCM, available between the proposed FRL and MDDL, to be adequate for peaking operation
of the station for about 44 hours in a week with flows corresponding to the minimum mean
discharge (MMD) and releases within the daily volume restrictions of 50% to 130% of the
corresponding daily inflows permissible within the scope of the Indus Water Treaty. The
average load factor of the operation of the main power house during lean period would be
about 10.1%% ensuring peak operation of the power house for about 2.4 hours daily. Annual
Plant Load factor of the main station would be about 43.00%. The firm power from the project
shall be118.8 MW. The power generated will be helpful in mitigation of the power shortage in
Northern Grid. The project, proposed to be completed in five years’ time frame, shall require
1200 persons including professionals, technical, skilled and unskilled labours during the peak
construction stage.

regarding.Sir,
This is with reference to your letter no. Cl&D/571-1117165'79 dated 6.2.2012 and
9.1.2013 on the above mentioned subject.
Z. The proposal was eartier submitted for scoping ctearance for 990 MW. The ftow
series have been approved by CWC on 1.9.2011. The flow series corresponding tomonsoon flow in 90/. dependab[e year ranged from 673.7 to 1038.8 m3/sec, and a design
discharge of 512 m3/sec'with bifuication of 413.47 m3/sec for 840 MW (6x140 MW) main
undergiound powerhouse and 99.17 m3/sec for 90 MW dam'toe powerhouse has been
adopt6d. 20% retease in lean season ftow ranging from 50 to 70 cumec was reported
adequate to meet the downstream retease. As a resutt of downward revision of capacity
from 990 MW to 930 MW, there witt be no submergence of Paddar Vattey. The projectproposal was considered by Environment Appraisat Committee (EAC) for,River Vattey and
hydroetectric Projects in iis meetings hetd on 30-31't March, 2012 &.1-2nd February, 2013-
The comments ani observations of EAC on the proposal may be seen in the minutes of the
meetings, which are avaitabte on the web-site of this Ministry.
3. tt is noted that the project envisages construction of a 121 m high concrete gravity
dam across river (165 m from the deepest foundation levet) Chenab to generate 930 MW
of hydropower. The catchment area of the project is 9987 Sq. Km. Totat tand requirementis about'416.25 ha, out of which 227.25 ha is forest [and, 40 ha is government land and
149 ha is private tand. Totat submergence area is about 331 ha. (Of which 155 ha isforesttand). An unflerground powerhouse is proposed with 6 units of 140 MW each + 90 MW
(2$b MW ; 1x10 MW) auxitiary dam-toe powerhouse facititate to release ofenvironmental ftows is atso proposed. About 15 famities witl be futty affected due to thisproject. Tota[ cost of the project is about Rs. 6087.48 Crores.
4. Based on recommendations of the EAC, the Ministry of Environment & Forestshereby accords ctearance for pre-construction activities at the proposed site as per theprovisions of 'the Environmental lmpact Assessment Notification, 2006 and subsequentamendment, 2009 atong with the fottowing Terms of Reference {TOR) for preparation ofEIA/EMP report. The EIA/EMP report shoutd contain the information in accordance withprovisions & stiputations as given in the Annexure-1. White preparing the EIA/EMP reportprevaiting norms shoutd be foltowed with respect to environmentat ftows, muck disposalsites and other parameters.
The Committee expressed its satisfaction over reduction in capacity from 990 MWto 930 MW as with this; land requirements and submergence area have come down,thereby saving Peddar vatley. The committee thus, agreed to the downward revision ofthe capacity of project to 930 MW subject to the fottowing conditions/additionat TORs:
. Keeping in view the proximity of protected forest [and, the Environmental Sensitivityis to be properly assessed and reftected in the EIA
o The EIA/EMP shoutd atso inctude the foltowing:
(i) Enumeration of atl ptant species betonging to atl groups, especiatty trees - number oftrees of eacli species and their volume in the submergence area; (ii) Studies onEconomic vatuation and Ecosystem Services will be carried out on the forest tost (iii)EMP: For Compensatory afforestation tree species affected in the forest witt be utitizedfor ptanting.
. Land cover and land-use pattern shoutd be given with Fatse Cotour Composition (FCC)o Flora of the Project Area: "29 taxa of flowering plants" appears to very [ow. Detaits
about Gymnosperms, Pteridophytes, shrubs and herbs are-to be presented in the EIAreport.
o The sampting locations are to be given.. Sampting tocations for ftorat/faunal studies appeared to be inadequate. Champion &
Seth (1968) shoutd be fottowed for forest typeso Environmental Evaluation: detaits of the environmentat evatuation should be given
and detaits of forest land/flora and fauna have to be presented in the EIA reporto Proposed Engineering and Biotogical measures: Use Coir mats - geotextiles on stopes
to prevent soil erosion and for raising plantations.. A study on environmentat ftow retease needs to be inctuded. Draw a separate cotumn
giving environmental ftow, spitt ftow, turbine ftow and ftow through the dam-toepowerhouse. Check the total retease d/s dam as per the prescribed norms. ln anycase retease of minimum environmental ftow must mimic the pre-dam flow patternof the river for sustaining the aquatic bio-diversity together with downstream userneed and accordingty, water withdrawal for power generation is to be regutated.Minimum environmental ftow retease would be 20Yo of average of four tean months oflean period and 20-30% of flows during non-tean and non-monsoon periodcorresponding to 90% dependabte year. The cumulative environmental ftow reteasesinctuding spittage during the monsoon period shoutd be about 30% of the cumulativeinflow during the monsoon periods corresponding to90/o dependabte year.
. The estimated PMF shown as 8140 cumec, whereas, the peak ftood hydrograph shows7440 cumce. This needs to be exptained/ reconciled in the EIA report.
5. The Consuttant engaged for preparation of EIA/EMP report has to be registeredwith Quatity Councit of lndia (QCI)/NABET under the scheme of Accreditation &Registration of MoEF. This is a pre'requisite.
6. Consultants shatt inctude a "Certificate" in EIA/EMP report regarding portion ofEIA/EMP prepared by them and data provided by other organization(s)/ laboratoriesinctuding status of approval of such laboratories.
7. The draft EIA/EMP report prepared as per the above Terms of References shoutdbe submitted to the State Potlution Control Board / Committee concerned forconducting Pubtic Hearing /Consuttation as per the provisions stiputated in EIA

EXECUTIVE SUMMARY
1.1. Introduction
The state of Jammu & Kashmir lies between 32 17’ to 37 05' North latitude
and 72 26' to 80 30' East longitude. The geographical area of the state is 2,
22,236 Sq.km. The population of the state as per the census of 2011 is
12541302 persons, with population density of 124 persons per sq. km and
decadal population growth rate of 23.64%.
Kirthai Hydro Electric Project Stage-II is a run of the river scheme on the River
Chenab and is located in tehsil Padder of district Kishtwar of Jammu and
Kashmir. The proposed dam site is about 13 km downstream of Kirthai Hydro
Electric Project Stage-I. Kishtwar town is about 58 Km downstream of the
proposed dam site. The dam site is located at 33 18’ 41’’ N and 76 04’ 37”E.
The Powerhouse is proposed at Lidrari which is about 8 km downstream of the
dam site. The power house site is located at 33 19’ 20’’ N and 76 00’ 52”E.
The location plan of the project is presented at Annexure-1. The lay out plan
of the project is presented in Annexure-2.
Total Installed capacity of Kirthai Hydro Electric Project Stage-II has been
proposed as 930 MW.The Firm Power of the project is about 118.80 MW. The
installed capacity of main power house is 840 MW and that of Dam toe power
house is 90 MW. The water from the dam would be diverted to an underground
power house near Lidrari on the left bank of the Chenab river through 4.289 km
long HRT for power generation with an installation of 6 units of 140 MW each
operating under a net head of about 225m.The annual energy generation
benefits from the project at the main power house which is underground have
been estimated as 3160 MU in 90% dependable year with annual design
energy generation benefits as 3055.89MU. The average load factor of
operation of the main power house during lean period would be about 10.1%
ensuring peak operation of the main power house for about 2.4 hours daily.
Annual Plant load factor of the main power house would be about 43%.
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 2
In addition, a dam toe power house with 2 units of 35 MW each and another 2
units of 10 MW each have also been envisaged to utilize the flows to be
released directly from the dam into the river for environmental purpose. The
annual and the design energy generation benefits at the dam toe power house
have been estimated at about 307.19 MU and 296.17 MU respectively in 90%
dependable year.
1.2. Access to the Project Area
As of now, the proposed Project site can be approached from Jammu Airport
and Jammu Railway Station through Jammu - Kishtwar National Highway up to
Kishtwar, which is 240 km away from Jammu. Beyond Kishtwar up to Project
site there exist an all weather road maintained by BRO. The dam site is 58 km
away from Kishtwar and power house site is 50 km away from Kishtwar . Both
dam site and power house site of the project are on road head of existing
Kishtwar -Gulabgarh- Sansari road . Nearest railway station is Udhampur which
is 232 km from Project site.
1.3. Climatic Conditions in the Project Area
The climate of Project site is temperate. There is snowfall during winter season
and summer is very pleasant. The average monthly rainfall is about
1048mm.The winter is very cold and recorded temperature in winter is very low.
1.4. Historical Background of the Project
To utilise the share of water of river Chenab as per Indus Water Treaty, a
perspective plan for power potential of Chenab Basin was initiated and 14
schemes were identified during the 1st meeting of Chenab Co-ordination
Committee under the erstwhile Ministry of Irrigation and Power, Govt. of India
held on 19-11-1961. The fourteen schemes identified were as under.

Out of these 14 schemes identified for investigations, Central Water
Commission (CWC) was entrusted with the responsibility of investigations of 6
schemes, whereas Govt. of J&K and Govt. of Himachal Pradesh (H.P) were
allocated 3 and 5 schemes respectively. Central Water Commission completed
the investigations of all the 6 schemes as entrusted to it.
Govt. of J&K and Govt. of H.P could not complete the investigation work as
assigned to them. As Govt. of J&K could not do the investigation work for the
Kirthai H.E. Project, the investigation work of this scheme was also handed over
to CWC by Govt. of J&K in July 1988.
1.5. Earlier Proposals
The Kirthai Storage scheme was originally proposed to create 0.6 MAF storage
on the river Chenab as permitted under the Indus Water Treaty between India
and Pakistan (1960). Initially, it was envisaged to have a 212 m high concrete
dam near village Kirthai (76º-6’-12” E, 32º –17’-10” N) in Padder valley of Distt.-
Kishtwar, J&K, so that the wider portion of the river valley between Kirthai and
Atholi could be utilized for optimum possible storage. It was proposed to provide
8 km long Head Race Tunnel (HRT) with underground Power House located at
Lidrari (76º-1’-6”E & 33º-10’-33”N) to produce 750 MW power. The scheme
remained under preliminary investigations by the Power Development
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 4
Department, J&K, from year 1977 to 1988, when it was taken over by the
Central Water Commission in 1988 for feasibility studies.
After taking over the work of investigation of Kirthai Storage scheme by Central
Water Commission, it was found that the proposed Dam axis will submerge the
beautiful Padder Valley, the only valley in the upper reaches of the Chenab
with, agriculture land of about 643 hectares and forest area of about 1760
hectares. Central Water Commission tried to identify alternative dam sites with
power house at Lidrari.
1.6. Alternative studies
Four alternative dam sites across River Chenab were identified and studied by
Central Water Commission in consultation with the GSI. The entire four
alternatives are shown at Annexure-3.
1st Alternative Site was located downstream of village Kirthai with underground
power house at Lidrari. For this alternative three dam sites all downstream of
village Kirthai were studied.
2nd Alternative Dam Site was identified upstream of Gulabgarh suspension
bridge. This site was located near Gulabgarh. The river Chandra Bhaga
(Chenab) flows through a deep gorge for a few kilometers upstream of the
suspension bridge. The proposed dam axis was 250 m upstream of the
Gulabgarh bridge. The site was studied for a high concrete dam and 18 km long
Headrace Tunnel was proposed leading to an underground power house near
Lidrari nallah.
3rd Alternative Dam Site was same as of alternative 2nd but power house site
was within or near the body of dam.
4th alternative Dam Site was identified at Silper/Kidur with underground power
house at Lidrari.
All these alternatives were studied in detail by CWC in association with GSI and
a high dam at any of the alternative was not found feasible. The 1st alternative
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 5
had proposed dam site downstream of Kirthai village and high dam at any of
proposed locations of this alternative would have submerged land of Padder
Valley. The 2nd alternative had proposed dam site upstream of Gulabgarh
Bridge. The problem of submergence of Padder valley was avoided but the
proposed 18km long Headrace Tunnel had to cross many nallahs on its way.
The Geological features en-route would have posed many tunneling problems
besides non-availability of suitable construction Adits. Though some locations
for adits are available, these would be very long. The completion of such a long
Head Race Tunnel would invite innumerable construction problems.
After detailed comparative study of all the four alternatives it was found that
combination of 3rd and 4th is best for this scheme. This combination allows full
exploitation of power potential available in this reach of Chenab river and would
avoid submergence of precious land of Padder valley.
1.7. Splitting of Kirthai storage scheme into two stages
After detailed desk studies and visits of inter-disciplinary teams of CWC, GSI &
CEA, Kirthai storage scheme was decided to be split into two stages i.e.
Kirthai Hydro Electric Project stage-I and Kirthai Hydro Electric Project StageII.
Both the stages have been proposed to be run of the river schemes. The Dam
site of Kirthai Hydro Electric Project Stage-II was proposed near Silper or Kidur
with Underground Power House at Lidrari.
1.8. Kirthai Hydro Electric Project stage-I
The dam site of stage-I was proposed about 250m upstream of Gulabgarh
Bridge. Soon after finalizing the Dam axis and Power House locations, CWC
started detailed field investigation. Field investigation work of the project was
affected considerably due to non-conducive conditions in the state during 1993-
99 due to which work remained suspended during that period. Hence, the DPR
of the Project could be submitted in 2003. Keeping in view the provisions of
Indus Water Treaty, Kirthai H.E Project stage-I has been planned as run of the
river scheme and only 3 M cum of storage for peaking purpose has been
provided. The installed capacity of the Project was proposed as 240 MW (4 X
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 6
60) MW in DPR. A 160m high concrete dam with central spillway and
Underground Power House just downstream of Dam axis on left bank was
proposed for stage-I Project. The DPR of this Project has been handed over to
JKSPDC and at present it is in pre-construction stage. PMF Studies of Kirthai
–I was revised by CWC and PMF value was increased from 7400 cumec to
9140 cumec. The installed capacity of this project is now increased from
240MW to 390MW.
1.9. Kirthai Hydro Electric Project Stage-II
The releases from stage-I project was planned to be utlised by constructing
another project about 13 to 14 kms downstream of Gulabgarh. In addition, this
proposed project would utilize the flows of Bhutnala and Hanswar nala also,
which bring considerable flows even in the lean season. The power house site
for the Stage-II Project have been planned just upstream of Lidrari nallah
junction with the river Chenab. The power house would be Underground
structure and tail water would be carried to the main river through a Tail Race
Tunnel (TRT).
1.10. Study of alternative dam sites for stage-II
Two possible sites for Dam of Kirthai-II Project have been identified by CWC
and GSI viz. one near the place called Silpar about 5 km downstream of Kirthai
village and another just upstream of Kiddur Nala confluence which is about 1
km downstream of Silpar. The two alternatives are discussed as below:
1.10.1. Dam Axis near Silpar
This site is about 5 km downstream of Kirthai village. This site was found
suitable for a rock-fill dam also but clay for impervious core was not available
in that area. This site has granitic gneiss rock on both the banks. The width of
river bed at this site is about 70m. The river bed is approximately at EL. 1675
m and top of dam can be kept at EL.1760 m or so. The length of dam at dam
top would be around 250 m. The river reach is straight downstream of this dam
site for some length to ensure suitable energy dissipation. The length of tunnel
upto the underground power house near Lidrari would be approx. 6.0 km. It
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 7
may be possible to have a number of construction Adits 300-400 m long each
to facilitate construction of tunnel.
1.10.2. Lower Dam Axis U/S of Kidur Nallah
This site is about 1000 m downstream of above site and is suitable for a
concrete gravity Dam. The river gorge is deep and narrow and the rock exposed
on both the banks indicates availability of granitic gneisses on both the banks.
1.11. Selection of Dam Site and Power house
Both the sites were studied in detail by CWC and GSI and based on
technoeconomic comparison, the site U/S of Kidur Nallah was selected. This
site has geological advantage over site at Silpar. Length of HRT and width of
dam is less for this site as compared to site at Silpar. The power house site was
also shifted 80m towards HRT on advice of GSI because on earlier site it was
found that lateral cover was not sufficient because of Lidrari nallah .Detailed
field investigations were started by CWC from 1998-99 but progress was
hampered considerably due to security issues because of militancy. The dam
and power house sites of Kirthai-II projects were located in isolated places away
from inhabited area and practically it was very difficult to carry out field
investigation works in project area due to security reasons. The Staff of CWC
tried their best and submitted the DPR in July 2010 after completing the field
works.The installed Power Potential of the Project was 990MW (6X165).
EIA and EMP studies of the project are being carried out by developer of the
project i.e. JKSPDC.
1.12. Proposal for revision of DPR
While carrying out power potential studies of the project it was felt by CWC,
CEA & JKSPDC that the intermediate Nallahs/ streams joining the river will be
sufficient for environmental flows. However, when JKSPDC made a
presentation in MoEF in March 2012, it was desired by MoEF that the exact
quantity of flows in these Nallahs/ streams be given. Since, there is no gauge
or discharge site of state or CWC on these Nallahs/ streams, the exact quantity
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 8
of flows could not be given. However, an attempt was made to work out the
discharge with catchment area proportion. It was found out that the catchment
area of major Nallahs between downstream of Kirthai-II to outfall of TRT was
very less and was not sufficient for environmental flow as per latest guidelines
of MoEF. As per latest guidelines of MoEF, environmental flow releases should
be 20% of average of 4 lean months of 90% dependable years and 30% of
monsoon period from June to September.
A meeting was taken by Member (Hydro), CEA on 22.08.2012 at CEA, Sewa
Bhawan, New Delhi to review the status of DPR of Kirthai Hydro Electric Project
Stage-II. In this meeting representatives from JKSPDC, CWC, GSI & CSMRS
had participated and discussed the issue of environmental flow releases. It was
discussed that if environmental flow is released as per latest guidelines of
MoEF then there will be an overall effect on most of the parameters of the
project. GSI, Delhi has also raised certain observations regarding additional
drilling and drifting. It was decided in the meeting to carry out the additional
investigation works and revise the DPR.
Hydrology (N) directorate of CWC revised the PMF of Kirthai Hydro Electric
Project Stage-II from 7440 cumec to 9600 cumec on 20.2.2013. Power potential
studies of the project were revised based on latest guidelines of MoEF for
releasing of environmental flow. However, to utilise this flow to be released
directly from the dam into the river for environmental purpose, a dam toe power
house (located close to the dam site) have been envisaged with an installation
of 2 units of 35 mw and another 2 units of 10 MW .But still the installed capacity
of the project including capacity at dam toe power house was reduced to
930MW due to requirement of sufficient release of water for environmental
purposes.
1.13. Important Project Features
1.13.1. Concrete Dam:
A Concrete Dam 121m high has been proposed for Kirthai Hydro Power Project
Stage-II. The length of dam at top is 219.8 m .The overall length of the spillway
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 9
section of the dam is 93 m comprising five numbers sluices each of 9m width
with crest elevation at El.1712.50 m and one maximum overflow spillway ogee
type of 4 m width, with crest elevation at El. 1760.00 m. The overall length of
the non overflow section of dam would be 126.80 m extending on both sides of
spillways. Considering Free Board requirements, the top of the dam has been
kept at El. 1766.00m. A 1.0 m high solid parapet wall has been provided on the
upstream side
1.13.2. Coffer Dams and Diversion Tunnel
For the purpose of managing the river during excavation of foundation and initial
construction of concrete Dam, a Diversion Tunnel of diameter 10.5m has been
proposed on the right bank of the river. Length of diversion tunnel is 600.20 m.
For diverting the water through diversion tunnel an upstream coffer dam of
25.50 m height has been proposed. The height of downstream coffer dam has
been kept at 10.5 m.
1.13.3. Spillway
The spillway is located centrally in the river portion. The overall length of the
spillway is 93 m with 5 nos. sluice bays of 9 m each and piers of 4.5 m width
each. The crest elevation of the sluice spillway has been kept at El. 1712.50m.
The sluice spillway has been designed for a peak flood of 9600 cumecs which
corresponds to PMF. A maximum overflow spillway of 4 m
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 10
width has been provided in the pier of sluice. The crest elevation of the ogee
portion is at El. 1760.00m. The maximum overflow spillway has been designed
to pass logs and debris.
If the reservoir gets silted up to the crest level, there is possibility of boulders
rolling down over the spillway glacis. To avoid any damage to the spillway
surface due to rolling boulders, suitable protective arrangement has been
proposed by way of providing 0.5m thick high strength silica fume M50 grade
of concrete on the crest & glacis and around the sluice.
Energy dissipation arrangement
Various alternatives were considered for arriving at a suitable Energy
Dissipation Arrangement. It is found that only ski-jump type energy dissipation
arrangement will be effective. Further the bed rock is competent to withstand
the scour thrust.
Ski-Jump Bucket
A trajectory ski-jump bucket of radius 42.50m with invert elevation at
El.1678.75m and lip angle of 35 has been found to be sufficient for energy
dissipation purpose.
1.13.4. Power Intake
The FRL and MDDL of the Project reservoir have been kept at 1764.00 m and
1750.75 m respectively. The invert level of Intake is required to be kept
sufficiently low for preventing vortex formation at the entrance and sucking of
air into the tunnel at the lowest pond level (MDDL). For satisfying the above
requirements the center line of Intake has been kept at EL 1735.00 m.
Four Nos Bell Mouth intakes with invert level at EL 1731.80 m have been
proposed through the hill on the left bank of the reservoir. The design discharge
for the scheme has been worked out as 413.47 cumecs. The opening area of
size 5.785 m (width) x 6.40 m (height) has been provided after bell mouth
transition. Four numbers of power intake tunnels of 6.40 m dia. circular section
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 11
have been provided to draw 124.04 cumec discharge (including 20% for silt
flushing discharge) off taking from intake to feed four nos. of underground
desilting chambers spaced at 65 m c/c. The length of the four intake tunnels
varies from 916.62 to 1022.98m. Concrete lining has been provided in the
intake tunnels. Lining has been designed for internal water pressure and has
been checked for external water pressure. Metal trash racks are proposed to
be provided in front of the intakes for preventing entry of floating debris of size
larger than 75 mm
1.13.5. Desilting Chambers
Provision of four nos. underground desilting chambers of size 440 m x 19 m x
24.874 m (depth) each have been made to remove the silt particles of size
greater than or equal to 0.2 mm at 90% efficiency. To facilitate the construction
of desilting chambers, a construction adit of size 7 m x 7 m Dshaped has been
proposed which will bifurcate into two adits of size 7 m x 7 m each to reach at
top and hopper portions of the chamber.
The silt deposited at the bottom of the desilting chamber is to be collected and
transported through the silt flushing conduit provided at the bottom. After
coming out from desilting chamber this conduit has been provided with a gate
to regulate the required discharge. All the four nos. of silt flushing tunnels, after
the gate, join into a single tunnel which finally drops the silt back into the river
Chandra Bhaga (Chenab). The outlet of the flushing tunnel would be sufficiently
d/s of the dam to obtain the required head for flushing while being above the
maximum river water level at the outlet location.
1.13.6. Head Race Tunnel
One circular tunnel of diameter 10.50m and length 4.289 km is proposed to
carry design discharge of 413.47 cumecs from Desilting Chambers to the
Underground Power House. It is proposed to provide two nos. of construction
adits for the HRT one each at start & end. A total number of four working faces
would be available for construction of the HRT. The slope of HRT has been
worked on the basis of the analysis of surge shaft for down surge case.
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 12
The HRT is proposed to be constructed with a gradient of 1 in 296. The invert
level of HRT at RD 0.0 has been fixed in such a way that in no case during its
filling, the air is trapped between intake gate and HRT.
1.13.7. Construction Adits
The D- shaped section of size 7m x 7m has been adopted for the adits with a
mild slope towards adit portals to facilitate gravity flow of the seepage water.
The lengths of construction adits at upstream & downstream location of HRT
are 391.5m & 469.9m respectively.
1.13.8. Surge Shaft
Considering the geology and topography of the area, location of power house
complex, bore hole data and maximum surge level etc. the center line of
31.60m dia. Surge shaft has been located at RD 4289 m of HRT. From the
analysis, the maximum up-surge level works out as EL1790 m and minimum
down-surge level as EL. 1728 m. Accordingly, the top of the surge shaft has
been fixed at EL.1800 m giving sufficient water cushion over the maximum
upsurge level. Similarly a sufficient water cushion has been provided at the
junction of HRT with the surge shaft bottom. The over-all height of surge shaft
works out to 91.875 m and dia of surge shaft is 31.60 m. The surge shaft is
provided with a dome of size 37 m x 37 m with its top at EL. 1815.00 m. Three
nos. pressure shafts of 5.25 m diameter each off-take from the surge shaft at
centerline EL. 1711m. One Butterfly Valve Chamber of size 94 (L) X 12 (W) X
20.875 (H) has been provided downstream of Surge Shaft at 30m distance to
enable dewatering of the pressure shafts, when required, for carrying out
maintenance/ repair works for pressure shafts and main inlet valves.
A 7m x 7m D shaped Construction Adit of length 469.9m has been provided
towards the end of HRT for construction of both the surge shaft and HRT.
1.13.9. Pressure Shaft
Underground vertical/ horizontal pressure shafts have been proposed to convey
the water under high pressure from surge shaft to the power house.
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 13
Considering the amount of discharge and head involved, as well as the number
of turbines to be fed, it has been decided to provide three steel lined pressure
shafts of 5.60m dia each. These Pressure shafts would emanate horizontally
and radially (60 apart) from the surge shaft at centerline EL 1715.75m. The
shafts would become parallel to each other after attaining a center line distance
of 35m between them. After traversing a horizontal distance, these shafts will
bend downwards vertically and run horizontally at EL.1521 m (center line of the
turbine nozzles), each pressure shaft bifurcating further, near the power house,
to a size of 3.75m dia, to feed the six generating units.
An 8m x 9m D shaped Construction Adit in the bottom horizontal portion of
pressure shafts has been provided for construction of pressure shafts and lying
of bifurcation pieces of steel liner.
1.13.10. Power house
Six units, each of 140 MW capacity with vertical axis Francis Turbine have been
proposed to be installed in the power house located on the left bank. The size
of Power house has been proposed as 187.50 (L) x 22m (W) and 49.70m (H)
respectively. The centre line of machine hall is kept at EL 1521m and the top
EL of Power House is 1557.50m.The generating units would be spaced at 22m
center to center.
The water emanating of the turbine/power house is carried through a circular
draft tube of 5.10 m. All the six draft tubes are provided with a gate, which will
be operated from transformer hall.
The Transformer and GIS Bay would be in an underground cavern located at
40m d/s of the power house cavern. The size of transformer & GIS cavern is
191 m (L) x 18 m (W). It accommodates 20 unit transformers at EL. 1534.00m
which is same as the service bay level. Gas insulated switches (GIS)
equipments will also be installed in this cavern at an EL. of 1543.50m.
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 14
The water emanating from the draft tube fed into the river Chandra Bhaga
(Chenab) through 10.50 m dia TRT of 352.50 m length. The invert level of outfall
has been kept at E.L.1523.00 m which is below the TWL of 1527.50 m.
1.13.11. Dam Toe Power House
A dam toe power house has been planned for a design discharge of 99.71
cumecs. Four units of capacity, two of 35 MW each and two of 10MW each
have been proposed to be installed with vertical axis Francis Turbine in the
surface power house. Power House is planned on right bank of the river at the
toe of dam block number 9. Power Intake for dam toe power house has been
provided in the dam block. A 5.8m diameter steel penstock starts downstream
of intake gate transition, comes out at dam fall and runs down to EL 1650. A
bifurcation piece is provided to bifurcate 5.8m diameter penstock into two
penstocks of 5.1m dia. and 2.7m dia. penstocks. Further 5.1m dia. penstock
drops down to EL 1649m and bifurcates into two unit penstocks of dia. 3.6m
each. Similarly, 2.7m dia. penstock also bifurcates into two unit penstocks of
1.8m dia. each. Penstocks are covered with M15 grade of concrete below EL
1667m.A surface power house is provided in front of dam block number 9. The
bottom of power house is at EL 1639.5m. Service bay and machine hall has
been provided at EL 1658.30m. Transformer hall and GIS have been provided
behind the power house at EL 1659 m and EL 1667 m respectively.
Draft tubes of these machines are provided with a gate which will be operated
from the deck at EL 1659 m. The dimensions of surface Dam Toe Power house
is 78.525m X 24 X 36.5 m(H).
Tail race channel has been provided in form of draft tube which discharges the
power house discharge into river. It has a slope of 4(H): 1 (V) and has weir at
EL 1656m which is the minimum tail water level.
1.14. Need for the Project
Kirthai Hydro Electric Project Stage-II is a run of river scheme having both direct
and indirect benefits. Hydro power generation is the major direct benefit of the
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 15
Project. In addition to this, there will be indirect benefits also such as fillip in
tourism, infrastructure development in the form of roads and buildings. Besides
this the Project will have a potential for employment generation which will help
in the socio-economic development of the people of the region in particular and
state in general.
1.15. Direct Benefit
1.15.1. Power:
The estimated hydro power potential of the State is 20,000 MW, out of which
about 16480 MW have been identified. Out of the identified potential, only
2456.2 MW i.e. 15 % (of identified potential) has been exploited so far,
consisting of 760.46 MW in State Sector from 21 power projects, 1680 MW from
four power projects under Central Sector i.e. {690 MW Salal, 480 MW Uri-I, 390
MW Dulhasti and 120 MW Sewa-II Hydel Projects} and 17.5 MW from two
private sector projects. The installed capacity of 760.46 MW from state sector
projects includes the 450 MW of Baglihar Phase–1. Due to resource
constraints, exploitation of the potential economic rejuvenator like hydro power
has been very steady. Besides, due to the constraints imposed by the
provisions of Indus Water Treaty between India and Pakistan preventing
storage of the water of Jhelum, Chenab and Sindh Rivers, these projects have
been constructed as run of the River projects. The State is therefore under
perpetually energy deficiency and has to rely on power purchase from Northern
Grid to meet its requirement particularly in winters, when its own generation
recedes and demand peaks. The graph given below depicts the identified,
harnessed and under construction power potential by J&K State and Central
Government.

The figure shows that from 2007-08 to 2012-13 the actual demand has
increased from 14037 MU to 17842.69 MU respectively. The power shortfall
has increased at an alarming rate. Recognizing the urgency and need of
development of hydro power, implementation of this project becomes very
important. The power of Kirthai Hydro Electric Project Stage-II will increase the
power availability of northern grid and J&K state will be benefited by this
additional power.
1.15.2. Indirect Benefits
1. Tourism
The artificial lake with a big water spread shall become one of the biggest
recreational spots in Padder area. It will attract more tourists for Machail Mata
yatra and hence increasing the tourist inflow and thereby increased revenue
collection from the region.
2. Infrastructure Development
Infrastructure like roads, bridges, buildings etc. will be built at a large scale at
the construction stage of the project which will ultimately benefit the local
population.
3. Employment generation
This project will create immense potential for employment generation as lot of
manpower both skilled and unskilled would be required during as well as after
the Construction of the project.
1.16. Geological and Seismic Studies of Project area:-
All the components of the project are located on the Pias Granite which is
intruded within the Kishtwar Window. The Kishtwar Window is a conspicuous
structural element of Higher Himalaya. It exposes Dul Quartzite enveloped by
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 18
Salkhala Formation, which is tectonically overlain by the high grade
metamorphites (Central Crystalline rocks) along the trace of Main Central
Thrust. The rocks of Kishtwar Window are overriding the younger Salkhala
Formation along Kiaji Thrust.
Geology of Dam site :- River width along the dam axis is about 85 m. River
bed level as observed on the right bank is about 1660 m above m. s. l. Left side
hill slope upto road level i.e., RL 1717 m is almost vertical and 15 m from the
slope edge, slope is slightly less steep (65°).Right bank abutment slope is
comparatively less steep (40°) upto dam top. Above the dam top slope is steep
and high. Both the abutments appear to be quite stable. However, a prominent
joint set trending N50º to 55ºW –S50º to 55ºE and dipping 50º to 80º towards
SW i.e., towards river side, is recorded. Opening along this joint set is noticed
upto 20 cm. To avoid stability problems along the joint plane, removal of
unstable rock blocks are felt necessary. At the dam site, granite gneisses with
thin to thick pegmatite veins intruded in the rocks of Kishtwar Window are
exposed. The rocks are generally fresh, massive and hard. Four set of joints
have been recorded in the area but no major structural discontinuity in the form
of thrust or fault has been noticed at dam site. The dam axis is aligned in N83°W
to S83°E direction. The dip and strike of the foliation in the rock units along the
dam axis is N35ºW-S35ºE and dip 45º towards NE. No major structural
discontinuity has been noticed at the dam site and adjoining area and none is
expected at foundation grade. Geotechnical studies have indicated that rocks
exposed at the dam site are quite competent for the proposed dam.
Geology of Diversion tunnel:- The 600.20 m long diversion tunnel with a
diameter of 10.5 m is proposed to divert water of the Chenab River during the
construction of the dam. It is aligned through a ridge along right bank near the
dam axis. The hill slope towards the river varies from 50° to as steep as 70°.
The area along the proposed tunnel is occupied by granite gneisses with thin
partings of schistose rock. The general trend of the foliations varies from
N15°W-S15°E to N55°W-S55°E dipping 30° to 70° North-Easterly. The tunnel
alignment will more or less follow the strike of the foliations of rock mass, due
to which the rock exposed at the inlet portal may continue for the major part of
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 19
the tunnel except near the out let portal where the tunnel makes a bend.
Reversal of the dip has also been recorded in the area due to folding.
Geology of Intake and Desilting chamber:- The detailed geological mapping
of the intake gates and desilting chambers was carried out on 1:1000 scale.
Both the components are located in the granite gneisses of Pias Granite which
is hard and fresh at the surface. The subsurface exploration of the dam body
was carried out which is located in the similar setup of rocks. The drift along the
left abutment of the dam axis is very near to the desilting chamber. No adverse
geological conditions were recorded during 3 D logging of drifts.
Geology of Head Race Tunnel (HRT) :- Headrace tunnel (HRT) is proposed
through left bank ridge made up of jointed to massive granite gneisses. Studies
reveal that 4.289 km long HRT along the left bank of Chenab river is aligned in
favorable Geological condition, almost cutting across the foliation / bedding
trend of the rock units represented by granite gneisses of Pias Granite, phyllites
and quartzite of Kishtwar Window exposed along the tunnel alignment. Two
thick bands of quartzite and phyllites of Kishtwar Window measuring 290 m and
950m are exposed along the HRT after crossing the Kidur nala and near
Shasho village. The minimum cover over HRT under Kidur nala is about 50 m
and maximum cover is in the order of 950 m. No major problem is anticipated
during the excavation of the tunnel except some wedge failures due to the
presence of shear seams which may cause over break.Water seepage problem
where the alignment is passing below perennial nalas cannot be ruled out.
Geology of Underground Power house :- The proposed powerhouse will be
located on the left bank hill just upstream of confluence of the Chenab River
with Lidrari nala. Detailed geological mapping of the underground power house
and tail race tunnel covering an area of about 0.075 sq. km was done. The
studies have revealed that massive and competent granite gneisses are
expected in the proposed underground power house and tail race tunnel. Rocks
are traversed by three prominent joints which are widely spaced. These joints
are also associated with shear zone varying in thickness from a few centimeters
to 3.5 m.The adjoining area also exposes phyllites and graphitic phyllite,
quartzites of Lopara Formation and Pias Granite as intrusive. The Lopara
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 20
Formation is the oldest rock unit in the area and occupies the lower most
Stratigraphical position and show comparatively higher grade of metamorphism
and is represented by slates, phyllites and graphitic phyllites. The
granite/granite gneisses, occurring as intrusive bodies, are the other rock units
in the area. The granites are medium to coarse grained and foliated. The
general trend of the foliation is N45°W - S45°E and dip varying from 30° to 45°
north-easterly. The overall rock quality is good. Granitic gneisses are exposed
in the area of the Tail Race Tunnel (TRT) and traversed by joint.
Geology of Reservoir area :- Traverse geological mapping of reservoir area
was carried out along the rim of the reservoir to identify the major structural
features, landslide zone, low topography area and any submergence of mineral
deposits .The rocks exposed in reservoir area are white Quartzite, phyllite,
sericite schist, granite and granite-gneiss of Kishtwar Window. The general
trend of foliation is N35°W/25°NE. Three sets of joints have been recorded. The
rocks are generally massive and compact. The rocks are in blocky in nature.
Minor shear zone have been noticed during mapping. Tectonically, two major
thrusts namely Kijai thrust and Atholi thrust are passing through the area which
is upstream of the reservoir tail. No impacts of these thrusts have been noticed.
Minor shear zone and shear seams have been noticed. From the overall
assessment of the reservoir area and its periphery,it is inferred that there is no
possibility of water leakage in the adjoining valleys or basins as the water divide
along northern as well as southern periphery is above 4000 m above MSL
whereas, FRL of the reservoir is at 1764 m above MSL. Since the reservoir
periphery is occupied by slope debris/river terraces at places particularly in the
tail part of the reservoir, after filling of the reservoir sliding at some points along
the periphery is anticipated this may not have any effect on the competency of
the reservoir but may add to the siltation problems in the reservoir.
Seismic Studies of Project area: - The Kirthai Hydro Electric Project Stage-II
(KHEP-II) is located in the highly seismic Himalayan tectonic province, which is
having complex geological setup. The region of the project site has been
subjected to several large magnitude(≥ 7.0) earthquakes such as the 4th April
1905 Kangra and 19th January 1975 Kinnaur earthquakes and the relatively
recent 8th October 2005 event of magnitude 7.6 in the KashmirKohistan region
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 21
near the India-Pakistan border to name a few. The project site is located in
seismic zone IV as per the zoning map of India (IS: 18932002, Part-1). Site-
specific design ground motion for KHEP-II site has been estimated by CWPRS
Pune by carrying out detailed analysis of the data on seismotectonic and
geological features and past seismicity in the region.
The site-specific horizontal design seismic coefficient for the dam is found to be
0.219 g dam. The corresponding vertical design seismic coefficients can be
taken as 0.146 g.

Chandra and Bhaga rivers join near Tandi in the districts of Lahul and Spiti in
Himachal Pradesh to form river Chenab. The Chandra and Bhaga originate
from the south-west and north-west faces of Baralacha Pass respectively in the
Himalayan canton of Lahaul and Spiti valley in Himachal Pradesh. Thereafter,
the river enters Padder area of Kishtwar district in J&K and is joined by
Bhutnallah at Gulabgarh. Chenab is also known as Chanderbhaga in upper
reaches up to Bhandarkot (Kishtwar).The River flows between steep cliffs of
high mountain up to project site. The river drains a catchment area of about
9987Km2 upto project site. The catchment area of the river up to dam site is
presented at Annexure 4.
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 22
The estimated hydro power potential of the Jammu and Kashmir State is 20,000
(MW), out of which about 16480 MW have been identified. A major portion of
this hydro power potential i.e. about 9017MW is on river Chenab, which is a
veritable goldmine for the state, waiting to be harnessed. Cascade
development of hydro-power in Chenab Basin is shown in Annexure 5.

The data at Arthal is limited up to the period 1990 and it will be advisable to use
the updated data therefore the use of Arthal data for the purpose of
development of flow series at the project site in the first instance is ignored.
The consistency of data of Gulabgarh and Premnagar has been checked at first
instance and Regression analysis has been carried out between Gulabgarh and
Premnagar data for the following periods from 1990-91 to 2008-09:
1. June - October
2. November - February
3. March – May
The R value has been found 0.8684, 0.4024 and 0.8532 for the periods June
to October, Nov to February and March to May respectively.
Then, Regression analysis was carried out between Udaipur and Benzwar data
from 1973-74 to 2002-03 and R value found to be 0.8749, 0.6408 and 0.8944
for the periods June to October, Nov to February and March to May
respectively.
The results of the Regression analysis carried out between Benzwar and
Premnagar sites from 1968 to 2003 has been found better regression

DPR: Vol-0: Executive Summary Page 23
coefficients as R value obtained was 0.9063, 0.7271 and 0.9270 for the periods
June to October, Nov to February and March to May respectively.
Since the correlation between Benzawar and Premnagar sites have been found
better out of these combinations and also the data considered is of longest
period (1967-68 to 2002-03); and also as the catchment area up to Benzwar
site is close to the catchment area of the dam site of kirthai-II H.E Project, the
data of Benzwar site has been considered as base data and the data for the
period 2003 to 2010 at Benzwar has been derived considering the relationship
so developed between Benzwar and Premnagar for the periods June to
October and March to May due to good correlation coefficients mentioned as
below:
June to October
YB = 0.6242X+38.117 R=0.9063
March to May
YB = 0.5531X-26.108 R=0.9270
The relationship for the period November to February where the correlation
coefficient is poor, the data of Benzwar has been derived on 10 daily
coefficients to the remaining 8 months volume of flow with Premnagar annual
flow for the respective year. The completed data series was transposed at
project site Kirthai-II on the basis of catchment area proportion and the flow
series at the project site for the period 1967-68 to 2009-10 have been
completed.
Dependable flow at 50% and 90% has also been computed. The 90%
dependability is found to be 8908 MCM (1971-72) and the 50% dependability
is 11630 MCM (1982-83).
Design Flood Studies.
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 24
Methodology
As the height of the proposed dam is more than 30m, the dam is classified as
high dam and design flood for fixing the spillway capacity will be Probable
Maximum Flood (PMF).
The Kirthai Hydro Electric Project Stage-II dam is proposed approximately 13
km downstream of the proposed Kirthai Hydro Electric Project Stage-I dam site.
The catchment area of Kirthai Hydro Electric Project Stage-II is 9987 sq.km and
catchment area of Kirthai Hydro Electric Project Stage-I is 8530 sq.km
respectively. The design flood for the Kirthai stage-II project is computed in two
steps. The PMF hydrograph of Kirthai stage-I is routed up to
Kirthai H.E. Project Stage

Analysis of sediment data
After analysis of sediment data, the average annual sediment rate of sites have
been worked out, which is given in Table 7 below. Benzawar site is located
quite close to this project site where average annual sediment rate, based on
observed data of 30 years, has been computed as 0.8625 mm/yr. Since, Kirthai
H.E. Project (stage-I) has been planned for a sediment rate of 1.072 mm/yr, the
same rate has been used for Kirthai HEP-II also for computation of sediment
volumes for various time horizons.

Estimation of New Zero Elevation and Revised Capacities using
Empirical Area-Reduction Method.
Kirthai Hydro Electric Project Stage -II is downstream of Kirthai H.E. project
stage-I. As per MOWR guidelines, only existing or under construction projects
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 27
are to be considered as trapping sediment on the u/s of a dam under planning.
However, as per BIS code, projects having same priority as the projects under
study may be considered as trapping the sediment. Accordingly, sedimentation
studies of Kirthai-II dam have been carried out considering both the scenarios,
i.e. with and without Kirthai-I HE Project.
Case-A-Entire catchment upto Kirthai-II contributing to the sediment inflow
(without Kirthai-I project)
Case-B- Kirthai-I is trapping sediment and balance is coming to Kirthai-II. New
Zero elevation after 70 years of sedimentation works out to 1746.3 m in Case-
A and 1741.4m in Case-B and the same are recommended for design
purposes.
1.19. Power Potential Studies
Input Parameters for Study
Studies for assessment of power benefits have been carried out by Central
Electricity Authority (CEA), New Delhi taking into account the Environment
Flows as well as without Environment Flows for which flow data is available.

Selection of FRL & MDDL
Kirthai Stage-II is located immediately downstream of the Kirthai Stage-I.
Therefore, dam height for Kirthai Stage-II would be governed by tail water level
of the upstream stage viz. EL-1784m. However, in order to avoid submergence
of fertile areas of Padder Valley, it has been decided to restrict the dam height
corresponding to FRL as EL 1764m. As such, the FRL for the Kirthai Stage-II
HE Project has been selected as 1764m.
Minimum mean discharge (MMD) for project has been worked out as 58.22
cumecs .Based on the availability of the above flows and Environment Flows of
10.98 cumecs, weekly operation of the plant has been carried out taking into
consideration volume restrictions as per Annex-D of the Indus Water Treaty.
The permissible Pondage, as per provisions of the Treaty, would be 18.54 MCM
i.e. twice the Pondage required for firm power however Pondage of 17 MCM is
being proposed for Kirthai-II.
From the area-capacity characteristics of the reservoir it is observed that based
on the above Weekly Pondage requirement of 17 MCM, MDDL for the project
would work out as 1750.75 m.
Firm Power & Installed Capacity
As per the Treaty, Firm Power means “the hydro-electric power corresponding
to the minimum mean discharge at the site of a plant”. Based on the minimum
mean discharge of 58.22 cumecs available at Kirthai-II, the Firm Power of the
project, as per the Treaty, works out as about 118.80 MW.
Power Output and Energy Potential for ROR project is proportional to the
natural inflow pattern. Energy Potential of Kirthai Hydro Electric Project StageII
has been worked out on 10-daily basis for the entire study period corresponding
to FRL-1764 m and MDDL-1750.75. Results of the studies are summarized in
below:

at Kirthai Hydro Electric Project Stage-II site varies from a maximum of 8291
MU (Year 1973-74) to a minimum of 4964 MU (Year 1997-98). The average
annual energy potential has been estimated as 6700 MU.

Selection of 90% Dependable Year
Power Output and Energy Potential for ROR project is proportional to the
natural inflow pattern. As such, corresponding to each alternative dam height
scenario, the 90% dependable year would remain the same. Therefore, for
selection of 90% dependable year for Kirthai H.E. Project Stage-II, the
unrestricted annual energy potential from the project corresponding to entire
flow period of 43 years has been arranged in descending order as given below:

have been proposed by CEA as under in their studies: Table 11 Environment
releases
Monsoon Period
(June to Sept.)
- 30% of the flow during the month
Non-monsoon Period
(Oct. to May)
- 20% of the average flow during Dec. to
Mar. in 90% dependable year.
Based on the above, the net flows have been worked out during 90%
dependable year and utilized for carrying out power potential studies have been
carried out for the project
Selection of Unit Size
The Main Power House is envisaged for operation as a peaking Station. For
selection of the unit size at the Main Power House, alternative unit sizes of 84
MW, 105 MW and 140 MW have been considered. However, the unit size of
140 MW has been proposed for the Main Power House since transportation of
the same to the site is unlikely to impose constraints. The smaller size units are
Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 32
likely to result in increased cost of civil works as well as E&M equipment.
Accordingly an installation of 6 units of 140 MW each is proposed at Kirthai
Hydro Electric Project Stage -II main power house.
With the above installation, the total discharge requirements from reservoir for
peaking would be about 413.47 cumecs and the unit discharge would be around
69 cumecs for main power house.
Further, the Dam Power House (to be located close to the dam site) has been
envisaged for operation as a Base Load Station and would be operated in order
to optimally utilize the Environment releases from the dam for power
generation. Based on the pattern of the power generation it is proposed to have
2 units of 10 MW each and another 2 units of 35 MW each at the Dam Power
House.

1.20. Land and Population Affected by the Project:
Kirthai Hydro Electric Project Stage-II is a run of river scheme and it has
pondage of 17MCM only. Reservoir area of the project is only 2.25 sq.km and
length of reservoir is about 9.8 km. Due to construction of this project some
portion of existing Kishtwar - Gulabgarh- Sansari road from dam site to Kirthai
village is likely to be submerged. The total length of existing road under
submergence is about 4.5km from Dam site to Kirthai. The tail end of the
existing road under submergence will be about 0.5 km downstream of Village
Kirthai JKSPDC in association with BRO is conducting survey for realignment
of the submerged road. Overall land requirement for the project is 225.25 ha
out of which 142.25 ha is forest land, 40.00 ha is govt. land and 43.00 ha is
private land. The land under submergence of the project is 140.00 ha out of
which 70.00 ha is forest land, 33.00 ha is govt. land and 37.00 ha is private
land. The breakup of land required including submergence area, land in respect
of different project components, colonies and offices, road, muck disposal area

1.24. Evacuation of Power to be generated at Kirthai Hydro Electric Project
Stage-II.
The evacuation of power from Chenab basin project in Jammu and Kashmir
was discussed and agreed in the 31st Standing Committee Meeting (SCM) on
Power System Planning of Northern Region (NR) held on 2nd January 2013
and subsequently in the 32nd Standing Committee Meeting of Power System
Planning of NR held on 31st August 2013. For Kirthai Hydro Electric Project
Stage-II the following transmission system was agreed as a part of high
capacity common corridor – I for hydropower projects located in Chenab basin,
J&K.
(i) 400 kV D/C (Quad HTLS Conductor – Equivalent to about 3000 MW)
line from Kirthai Hydro Electric Project Stage-II to Kishtwar Pooling
station.

Kirthai H.E. Project Stage-II (930 MW)
DPR: Vol-0: Executive Summary Page 38
The river Chenab, on which Kirthai Hydro Electric Project Stage-II is envisaged
for execution, crosses international boundary between India and Pakistan. It is
Western River of Indus Basinand falls in the purview of Indus Water Treaty
1960.
Since the Kirthai H.E. Project is proposed on river Chenab which is a Western
river, Water Resources Project on this river is guided by the Annexure “D” and
Annexure “E” of the Indus water treaty which deals with the provisions regarding
generation of H.E. Power and storage of water by India on the Western rivers.
Indus Water Treaty has XII Articles with VIII Annexures.
Kirthai Hydro Power Project Stage-II is a run of river scheme and is within the
provision of Indus Water Treaty. It is planned and designed as per Article III
Annexure D and Annexure E of the Treaty.
Minimum mean discharge (MMD) for the Project is calculated as per Annex.-D
of the Treaty as under:
“The average discharge for each 10-day period (1st to 10th, 11th to 20th and
21st to the end of the month) will be worked out for each year for which
discharge data, whether observed or estimated, are proposed to be studied
for purposes of design. The mean of the yearly values for each 10-day period
will then be worked out. The lowest of the mean values thus obtained will be
taken as the minimum mean discharge.”
Based on the above, average flows have been obtained for each 10-daily period
and minimum of these flows represents MMD which has been worked out as
58.22 cumecs.
Firm Power of the Project has also been worked out as per Treaty.
As per the Treaty, Firm Power means “the hydro-electric power corresponding
to the minimum mean discharge at the site of a plant”. Based on the minimum
mean discharge of 58.22 cumecs available at Kirthai-II, the Firm Power of the
project, as per the Treaty, works out as about 118.80 MW.

Environment Flows of 10.98 cumecs, weekly operation of the plant will be
carried out taking into consideration volume restrictions imposed as per
Paragraph 15 of Part-3 of Annex-D of the Treaty.
As per Annex-D of the Treaty, the works connected with run-of-river Plant on
Chenab river at a site above Ramban are to be so operated that
(i) The volume of water received in the river upstream of the Plant, during
anyperiod of seven consecutive days, shall be delivered into the river below the
Plant during the same seven day period, and
(ii) In any one period of 24 hrs. within that seven-day period, the volume
delivered into the river below the plant shall not be less than 50%, and not more
than 130% of the volume received above the plant during the same 24 hour
period.
(iii) The period of 24 hours shall commence at 8 AM daily and the period
ofseven consecutive days shall commence at 8 AM on every Saturday.
