ABSTRACT
The currently existing three major options for power production in India and elsewhere are hydro, thermal, and nuclear. From the viewpoint of efficient production and low environmental cost, hydropower has become one of the most important clean sources of energy. India is endowed with enormous hydropower potential especially in the Himalayan region. Rainfall from southwest monsoon, northwest winter rains, and heavy snowfall in winter have been the primary sources of water potential in the region. The Indus, the Ganga, and the Brahmaputra, the three major drainage basins in the Himalaya, are huge sources for hydropower potential. Out of the total existing hydropower potential in India, 21% hydropower potential has been harnessed so far, 9.8% potential is under construction, and 69.8% potential is yet to be tapped.
