The 1500 MW (6 x 250 MW) Nathpa Jhakri Hydro Power Station (NJHPS) has been designed to generate 6612 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 06.10.2003 with the commissioning of entire station progressively by 18.5.2004. Since start of operations, the station has generated 49632 MU of electrical energy up to 30/09/2011. 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.

Notes:
This PPA does not govern the supply of 12% of annual generation which is required to be made to the state of Himachal Pradesh free-of-charge pursuant to Government policies. Due to the current imbalance between demand and supply in the Indian power sector, and the competitive rates at which we are able to supply power, we do not currently foresee difficulties with renewing the PPAs when they expire.] Each of our PPAs currently provide that in the event that it expires, the terms of the expired PPA will continue to govern our supply of electricity to such party until the execution of a new PPA or an extension thereto. |
