Besides the social and economic upliftment of the people in the project vicinity, the 1500 MW (6 x 250 MW) NJHPS has been designed to generate 6950.88 MU of electrical energy in a 90% dependable year with 95% machine availability. Besides, the project has been designed to give valuable peaking power to the Northern Grid.

The first unit of the project has been commissioned on 6.10.2003 with the commissioning of entire station progressively by 18.5.2004. since start of operations, the station has generated 20766.035668 MU of electrical energy so far. Out of the total energy generated at the bus-bar, 12% is supplied free of cost to the home state i.e. Himachal Pradesh. From the remaining 88%, 25% energy is supplied to HP at bus-bar rates and balance power has been allocated to different states / UTs of Northern Region by the Ministry of Power, Government of India. The power allocations of the station are as under:

* Uttarakhand had surrendered its share of power, which was reallocated by MOP, GOI to Punjab. Presently, Uttarakhand is buying power out of unallocated quota on requirement basis for which Power Purchase Agreement has been singed with them.

The Nathpa Jhakri Hydro Electric Project – NJHEP (1500 MW) being a central sector project of Northern Region, the power being generated is required to be supplied to the beneficiaries of Northern Region which are essentially nine in total. Power Purchase Agreements (PPAs) have been signed with all the beneficiaries. The tariff of the station is being regulated by Central Electricity Regulatory Commission from time to time.

So far, approx. Rs. 5080 crore has been realized by way of sale of power with 99.8% realization of the outstandings. The sales revenue as per billing done in 2006-07 has been a record high of approx. 1482.57 crore with 100% current dues realization. The capacity Index, an indicator of the Operational Efficiency of the plant has been 92.366% against the normative of 85% during Fy 2006-07. During the current financial year the project has achieved cumulative Capacity Index of 95.362% till August 2007. Besides, SJVN is constantly carrying out customer Satisfaction surveys from time to time and has achieved Customer Satisfaction Index of 98.75% during Fy 2006-07.

Commercial Performance
The year wise operational and financial break up is as under:

During the current financial year bills of about Rs. 996 crore have been raised against the energy supply uptill August 2007 and the project has so far generated 4425.32 MU till 10.9.2007.
