Hydro electric projects in Himachal Pradesh

 449-MW Duggar power project allotted to NHPC

The Cabinet decided to allot Duggar hydro electric project ( pangi area of chamba ) with capacity of 449 MW in NHPC for a period of 70 years after completion of which the project will revert to the state government with specified generation capacity, free of cost and free from all encumbrance, earlier alloted to tata group but decided not to proceed with it.

HYDRO ELECTIC POWER

Hydroelectric power, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy.

Hydroelectric power comes from flowing water, winter and spring runoff from mountain
streams and clear lakes. Water, when it is falling by the force of gravity, can be used to turn
turbines and generators that produce electricity

POTENTIAL OF H.P. 

Himachal Pradesh is extremely rich in its hydroelectricity resources. The state is having about twenty five percent of the national potential in this aspect. It has been estimated that about 27,436 MW of hydel power can be generated in the state by the construction of various hydel projects on the five perennial river basins no matter they are major, medium or small. Out of total hydel potential of the state, 8,418 MW is harnessed so far, out of which only 7.6% is under the control of Himachal Pradesh Government while the rest being exploited by the Central Government. The state government has been giving the highest priority for its development, since hydel generation can meet the growing need of power for industry, agriculture and rural electrification. It is also the biggest source of income to the state as it provides electricity to the other states also.

Himachal has enough resources to generate surplus power but, sometimes this is a misconception as in winters the power shortage overshoots ten lakh units per day due to less flow of water in rivers and at the same time increase in lighting and heating load. Due to increased industrialization and rural electrification this figure is expected to rise even further.

Completed projects :

Girinagar Hydel Project
Situated on the river Giri of the Sirmour District, Girinagar Hydel project has an installed capacity of 60MW, with 2 units of 30MW each. This project, which is run-off-the-river scheme comes under HPSEB and is operational from 29 years.

Binwa Hydel Project
The project with an installed capacity office 16MW comprising 3 units each, is located near Baijnath in District Kangra. The project is situated 25 km from Palampur and 14 km from Baijnath is constructed at an elevation of 1515 mets. above the mean sea level. This project constitutes a 62 mets. long tunnel that connects trench weirs in Banu Khad and Prahal Khud.

Sanjay Vidyut Pariyojna
Located in the Kinnaur district, on the river Bhaba is a completely underground project with an installed capacity of 120MW, comprising 3 units each of 40MW. The uniqueness of this project lies in its underground switchyard, a feature that no other hydel project in Asia can brag about. Completed in 1989-90, the estimated cost was about 167 crore rupees. The total length of tunnels including those secured in after completing the project is 12 km.

Bassi Hydroelectric Project
Bassi project(66MW) is an extension of Beas Power House (Mandi District) constituting 4 units of 16.5MW each. It utilizes the tail water of Shanon Power House of Joginder Nagar project and generates 145MW per annum.

Larji Hydroelectric Project
Larji hydroelectric project is on river Beas in Kullu district with an installed capacity of 126 MW. The project was completed in September 2007.

Andhra Hydel Project
Commissioned during the year 1987-88, the project has 3 units of 5.5MW which makes it 16.5MW of installed capacity. It is located in Rohru tehsil of Shimla district. The cost of the project was estimated to be around 9.74 crores, generating 89MW per annum and it transmitting to the state grid via the Neogli power house near Rampur.

Rongtong Hydel Project
Rongtong is a 2MW project that is located in the Lahaul-Spiti district on Rongtong Nullaha, a tributary of Spiti river. Located at an elevation of 3,600 metres in a snow adhered region, this was the first hydel project executed for the socio-economic upliftment of the tribals of this area. It is one of the highest in the world. The snow fed water runnel tapped at an elevation of 3,788 mets. is diverted through 2,825 mets. long channel and 259 mets. long tunnel into an open reservoir with a capacity of 14,000 cubic mets. Renovated by APE Power Pvt. Ltd., APE Power also renovate RUKTI (4 x 375 KW) Hydro Electric project.

Baner and Neugal Project
With the combined installed capacity of 12MW the projects are situated on Baner and Neugal streams respectively in Kangra District. Both of the streams emerge from Dhauladhar and join Beas in the form of tributaries in south.

Nathpa Jhakri Project
One of the major project on the Sutlej river is the Nathpa Jhakri Dam which generates nearly 1500MW of electricity. The project is funded by World Bank. its construction cost is around 8000 crores

Sainj Hydroelectric Project
Installed Capacity 100MW. 

Bhakra Dam
The Bhakra Dam has the first Dam to have come up on the Satluj river, it is one of the highest gravity dams in the world and has an Installed capacity of 1325 MW. The dam holds excess waters during the monsoon and provides a regulated release during the year . It also prevents damage due to monsoon floods. The dam provides irrigation to 10 million acres (40,000 km²) of fields in Punjab, Haryana, and Rajasthan.

NHPC
Founded- 1975 

Headquarters -Faridabad, India

NHPC Limited (erstwhile National Hydroelectric Power Corporation) ) is an Indian Hydropower generation company that was incorporated in the year 1975 with an authorised capital of Rs. 2000 million and with an objective to plan, promote and organise an integrated and efficient development of hydroelectric power in all aspects. Later on NHPC expanded its objects to include other sources of energy like Solar, Geothermal, Tidal, Wind etc.

At present, NHPC is a Mini Ratna Category-I Enterprise of the Govt. of India with an authorised share capital of Rs. 150,000 Million.
