Anandpur Sahib Hydel Project (HEP)

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 its left side. The power potential of the Anandpur Sahib Hydel channel has been tapped by constructing 2 No. identical Power Houses  at Ganguwal and Nakkian. The Ganguwal Power House is located approximately 19 KMs downstream (Anandpur Sahib Hydel Channel) Nangal Pond on   its tail race 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 race water from Nakkian Power House is being led into Sutlej River through Lohand Khud Escape.
Each Power House has been equipped with 2×33.5 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 97% on the average
