SHANAN POWER HOUSE, PSEB, JOGINDER NAGAR (110 MW):

INTRODUCTION:

110 MW Shanan Project is the most picturesque project in the beautiful surroundings of Himalayan ranges. It is situated in the North Indian State , Himachal Pradesh at an approximately longitude of 76 degree ? 51' East and latitude of 32 degree ? 2' North. It takes advantage of two small rivulets at an altitude of about 6000 ft., in Brot valley. The idea of harnessing a power potential of 4X12 MW (48 MW) initially was envisaged by Col. Battye, the then Chief Engineer of Govt. of Punjab in 1922. This 48 MW Stage Ist Project was constructed at the initial cost of Rs. 2,53,43,709/- and commissioned in 1932 and was officially opened by His Excellency, The Viceroy of India at Shalimar Receiving Station, Lahore on 10 th March, 1933.

Shanan Power House, 1 st Stage of 4X12 = 48 MW was renovated to 4X15 = 60 MW in 1982. No major work in the form of additions and alterations in Head works, water conductor system, Power House building was involved.

The Shanan renovation project was finally commissioned in December, 1982.

SHANAN EXTENSION PROJECT (50 MW).

As originally conceived by Col. Battye, the extension of the 1 st Stage of Uhl river Project was proposed by constructing an additional unit of 50 MW. This extension work mainly consisted of a new extended reservoir at Brot, laying of new penstock for 50 MW and construction of new power house building. Finally this project with unit of 50 MW was commissioned in March, 1982.

•  PROPOSED PROJECTS

•  SHAHPUR KANDI HYDRO ELECTRIC PROJECT (168 MW) It is envisaged to develop 168 MW Shahpurkandi Hydro Electric Project. The site is 11 KM down stream of Ranjit Sagar Dam and 8 KM up-stream of Madhopur head works in Distt. of Gurdaspur. It is proposed to construct 54.5 Mtr. high and 725 Mtr. long concrete dam and 7.7 KM long Hydel channel of capacity 385 cumecs. 2 No. power houses are to be developed, one of capacity 2x40 MW and second of capacity 2x40 + 1x8 = 88 MW. All the clearances like techno-economic clearance from CEA, environment and forest clearance of Ministry of Environment and Forests, approval from Planning Commission and TAC of Ministry of Water Resources have been obtained. The estimated power generation based on dependable year basis is 815 MUs. GOP approved the original DPR with cost updated at Sept.,2005 price level as 1945 Cr & decided to execute this project departmentally, with dam/channel & other civil works to be done by Irrigation Works, Punjab & Electro Mechanical works to be done by PSEB. Actual works have not commenced yet. Funds are being arranged for the project as a loan from REC/PFC. Punjab Govt. has revised the apportionment of Irrigation Component from 12.61% to 20.9% vide Govt. of Pb., Deptt. of Irrigation letter No.9/4/08-PJ(5) 6463 dt.15.4.2008 . The petition had been filed with PSERC through CE/Commercial on 18.7.08 for approval of revised cost estimate after this re-apportionment after obtaining approval from Chairman/PSEB. Case was heard by PSERC on 16.9.08 & decided that this petition is not maintainable, as such dismissed it. Accordingly, PFC was again approached for sanction of loan. PFC has demanded DPR to be revised and submitted for their consideration. DPR was revised & submitted to CEA through GM/Hydro, Shahpurkandi recently for onward submission to PFC after approval by CEA. GM Shahpurkandi attended the joint meeting of CWC and CEA at Delhi on 23.02.09. Apportionment of total cost of Project between Power component & Irrigation component earlier done by CWC was 87.39% & 12.61% respectively, which made power component Rs. 11.89 crore per MW which was very high. As per the discussions in the meeting with CWC/CEA, Irrigation component of the project has been increased to 31.32% by GM/Shahpurkandi after which per MW cost of the project comes down to almost Rs. 9.00 crore per MW. The revised project report as per above Irrigation component is submitted to CWC/CEA. The approval is under process. The land for the project stands acquired and an amount of Rs. 196 Crores has already been spent on it as Irrigation Deptt. has been doing Barrage related works . This project is likely to be completed during 12th plan.

•  II) 75 MW UBDC STAGE-III HEP UBDC Stage-III Hydro Electric Project envisages harnessing of hydro potential to the tune of 75 MW of UBDC Canal beyond the point where UBDC Hydel Channel merges with UBDC Canal. It is proposed to construct a 20.6 KM long Hydel Channel of capacity 375 cumecs, 9.2 KM long Escape Channel , also of capacity of 375 cumecs, 22.4 KM long Alternate Irrigation Channel of capacity 8 cumecs and 0.7 KM long Carrier Channel of capacity 195 cumecs. Power House-I proposed with three units each of 15 MW capacity (total 45 MW) while the Power House II will have two units each of 15 MW capacity (total 30 MW) . Escape Channel outfalls into river Beas about 9 KM down stream of Shally pattan. The project envisages annual generation of approx. 472 MUs. The total cost of completion of project is estimated to be Rs. 640 Cr. The project is envisaged to be executed on BOOT basis & for this purpose a private developer M/s Bhilwara Energy Ltd; has since been selected through global tendering. Implementation Agreement has been signed on 22.12.06. M/s Bhilwara Energy Ltd; also proposed enhancement in capacity & generation beyond 75 MW provided PSEB compensate them for the same. Board has approved this proposal & as such the Deemed energy of the Project shall now be 510MU. This decision of Board was made an agenda item for the consideration/approval of officers committee of Govt. of Punjab . It was decided by the Officers' Committee in the meeting held on 19.02.09 under the chairmanship of Chief Secretary, GOP that as the Developer has to install higher capacity machines with efficiency of 91.6% to utilize the available discharge of 340 cumecs at PH-1 and 161 cumecs at PH-II, the Developer i.e. Bhilwara Energy Ltd. may be compensated for this by increasing the deemed generation from 468 MUs to 510 MUs and correspondingly increasing the Energy Charges from Rs. 115.36668 crore to Rs. 125.7201 crore provided the Developer demonstrates that the machines installed by him can achieve the quoted higher efficiency of 91.6% . Accordingly an amendment to implementation agreement has been issued, as such, the capacity of project shall now be 85MW. Power will be purchased by the Board @ Rs. 2.49/unit for 30 years. Project is likely to be commissioned by the year 2011-12.

III SHAHPURKANDI EXTENSION (55.5 MW) Shahpurkandi Ext. is the another project which has been taken in hand for development and is at preliminary stage. This project is proposed to be developed by re-modeling the existing UBDC canal from Madhopur Head Works up to 65000 RD. It involves construction of 3 No. PHs having capacity 2x10.5 MW, 2x10.5 MW and 2x6.75 MW. The capacity of the channel after remodeling shall be 13500 cusecs and the total length of the channel shall be about 20 KMs. The cost of the project is approximately Rs.500 Cr. at Nov.2000 price level and the annual generation shall be about 192 MU.In view of the new hydro policy of GOI the hydro tariff is based on cost plus basis rather than on competitive tariff basis. Now the developer has to prepare the DPR and get the CEA approval along with other statutory clearances and also get the tariff approved from appropriate regulatory commission. As such, the execution of hydro projects on BOOT basis has become much easier. It has been decided to implement the project on BOOT Basis. Consultants M/s Feed Back Ventures, New Delhi have been appointed for preparation of RFQ & RFP documents and bid evaluation etc. for execution of the project on BOOT Basis. Global bids for expression of interest have been floated with the approval of Board. The Project is likely to be commissioned during 12th Plan.

ANANDPUR SAHIB HYDEL PROJECT (134 MW):

Anandpur Sahib Hydel Project is situated about 32 KMs. downstream of Bhakhra Dam towards Ropar side. This Project has been so named due to its vicinity to the famous historic Holy town of Anandpur Sahib, Birthplace of Khalsa . The Town itself is situated on the foot hills of picturesque Shivalik mountainous range and attracts thousands of people all the year around but more so during Holla Mohalla festival in the month of March. The famous Naina Devi temple is also situated nearby atop the hilly peaks of Shivalik. This Project was constructed to utilize additional water of Bhakhra Nangal System as a result of Interlinking of Beas and Sutlej Rivers at Dehar. This additional water has been utilized for power generation by constructing a new 34 KMs RCC Lined Canal named Anandpur Sahib Hydel Channel with 10,150 cusec capacity, taken off from left Bank of Nangal Reservoir (Nangal Pond) on the Sutlej river. This canal runs almost parallel to Nangal Hydel channel on the left side. The power potential of the Anandpur Sahib Hydel channel has been tapped by constructing 2 No. identical Power House at Ganguwal and Nakkian. The Ganguwal Power House is located approximately 19 KMs downstream of Anandpur Sahib Hydel Channel from Nangal Pond. Its tail water is taken to Nakkian Power House through a second stretch of approximately 11 KMs Canal. Both the Power Houses have been so located that gross head ( 92.69 Ft .) is equal in both the cases. The tail water from Nakkian Power House is being led into Sutlej River through Lohand Khud Escape.

Each Power House has been equipped with 2x33.5 MW Generating Sets coupled with Kaplan Turbine Make BHEL Hardwar, are being supplied water through steel penstocks of 6 meters dia. The Hydro Generators are of suspension type having 2 No. Guide bearings. The Turbine governor is of electro-hydraulic type and excitation system is of conventional type with pilot and Main Exciter. The power is generated at 11KV and stepped up at 132 KV, is further fed into Regional Grid for exclusive use of Punjab .

The Power Houses were commissioned during 4/5-1985 and it is being observed that all the 4 No. Machines of both Power Houses are being run satisfactorily since their commissioning on the full/part load as per availability of water, which depends upon the releases from Nangal Pond at Nangal. The requirement of water for full load running of Power Houses is approximately 10150 Cusecs.

The Power Houses of Anandpur Sahib Hydel Project are working quite satisfactorily from the date of commissioning without any major breakdown. Electricity is generated as per availability of water in the AHC. The plant is giving a very good plant availability factor to the tune of 94% on the average. The Anandpur Sahib Hydel Project is giving a satisfactory performance.
