1 POWER SCENARIO IN J&K The J & K State is endowed with huge and vast water resources in the form of permanent glaciers & ice bodies, inland water bodies viz. lakes & river systems. These are being utilized for water resource development projects. To tap water resources for hydropower development, the capacity that can be developed on the major river systems and its tributaries has been estimated as about 20,000 MW. The hydropower scenario has been examined based on latest information of projects implemented, proposed and under construction in the state. Based on these studies it is established that: i. Most of the State s Hydro power Projects are run-off the river type; ii. The present installed generating capacity in the State is only MW (just about 12%) against the Hydropower potential of 20,000 MW in the state; iii. The power shortage is less in summer months and far greater in winter months when river discharges dwindle down to the barest minimum. The position becomes alarming in Kashmir Valley during winter, when the entire mountainous region is snow bound and in the grip of extreme cold with higher energy requirement; iv. The state Government has installed Gas Turbines in the valley to generate 175 MW of Power and thus provide some immediate relief to the people; v. In order to make the state self-sufficient in power sector and to harness the western rivers of Indus Basin without disturbing the Indus Waters Treaty, the J&K Govt. has approved the IPP Policy to develop power potential in the State wherein investors, both national and international, have been asked to come forward and invest. J & K State has accorded top priority to harness the huge hydro power potential and has prioritized following nine projects for immediate execution :- S. No. H.E.

Environmental clearance in respect of the Project has been accorded by State Level Environment Impact Authority Govt. of J&K vide their letter no dated As per the findings of the socio-economic survey of the affected families due to this project, the details are as under: (i) Total number of families being affected 66 (ii) Total number of families losing land (fully affected) 1 (iii) Total number of families losing land only (partly affected) 1 (iv) Number of villages affected Present Status The IWT clearance has been obtained. State level EIAA has accorded clearance. Land acquisition is under process. Clearance has also been obtained from State Pollution Control Board and wildlife deptt. Tenders were invited for implementation of the through EPC mode. Process has been completed. Contract is being shortly awarded to the successful bidder/lowest bidder. 8. Dah Hydro Electric Project (9 MW) 8.1 General 9MW (3X3) Dah Hydro Power Project has been envisaged as a run of-the river scheme to utilize the hydro power potential of perennial discharge available in Dah nala, a tributary of Indus River. Page 16 of 20

17 8.2 Location Dah Small hydro power project is located on the Dah nala near Dah villages in Leh district of J & K. The site is well connected by road to all major towns of Ladakh region. The project site is located by the side of Kargil- Leh road via Batalik at a distance of about 735 Km from Jammu and 170 km from Leh. Diversion site is having longitude of and latitude of General information The annual yield from the catchment area of 161 sq.km works out to be MCM. Dah HEP is essentially a run-of-river scheme with little pondage, utilizing inflows of Dah Nala for power generation with a surface power house on the bank of Indus. The scheme can be operated as a base station with firm power of installed capacity of 9MW for 6 months and for the remaining six months the availability varies from 9MW to 4.68MW. Installed capacity of the project has been proposed as 9 MW comprising 3 units of 3MW each Pelton turbines.the annual energy generation is million units and the Design discharge is 3.54 m 3 The power generated will be stepped up to 133 kv through 3 No kva, 6.6 kv/133 kv step up transformer and shall be delivered to nearby 133 kv grid substation at Khaltsi which is at a distance of 30 km from generating station. Double circuit 133 kv line has been proposed and the cost included in the report. The power shall be generated between EL m and confluence with Indus El m, with a net head of m. The nala bed has an average slope of 1 in 20 at diversion weir site and its minimum average discharge is 1.83 cumecs. The high flood discharge of this nala at the location of the diversion weir is estimated to be 135 cumec. The total length of the water conductor system up to Power House of the project is about 3489 meters. The principle components of the project are as follows: a. A weir of 3.5 m high with 16m water way and 2.0 wide under sluice. b. Cut & Cover Feeder Channel of 65m length 1.6m bed width and 1.85m over all depth. c. Desilting Tank of 45 m length including transition and 6m width. Page 17 of 20

18 d. Cut & Cover Power Channel of 2751 m length and of size 1.4m wide and 1.85m deep. e. Forebay of 22 m length and 8 m wide with pondage depth of 2.5m. f. Surface Penstock of 1.25 m dia and 606 m length. g. Surface Power House of size m (length) x 19 m (Wide) x 18 m (high). h. Tailrace Channel of 113 m length and size of 1.5m (wide) and 1.85 m (deep). The total execution period for the entire works of the project including testing and commissioning shall be 48 months. The locations of all the components is so selected that it requires about 4.5 m wide strip of land for the Power Channel along hill slope in about 2751 m length, 450 Sq m at forebay and about 1500 Sq m area for Power House. It does not cause any environmental and ecological imbalance of the area. No resettlement is involved. 8.4 Present Status The project was tendered out for implementation on EPC basis. All requirements as per the tender documents have been completed. The project is being awarded to the successful/lowest bidder. All the necessary clearances including the Indus Waters Treaty clearance, Pollution Control Board clearance, clearance from irrigation Deptt. are available. Power purchase agreement has also been signed. Land is available and its acquisition is under progress. 9. Hanu Hydro Electric Project (9 MW) 9.1 General 9MW (3X3) Dah Hydro Power Project has been envisaged as a run of-the river scheme to utilize the hydro power potential of perennial discharge available in Hanu nala, a tributary of Indus River. 9.2 Location Hanu HEP is located on the Hanu nala near Hanu villages in Leh district of J & K. The site is well connected by road to all major towns of Ladakh region. The project site is located by the side of Kargil- Leh road via Batalik at a distance of about 705Km from Jammu and 145 km from Leh. Diversion site is having longitude of and latitude of General information Page 18 of 20
