HYDRO POWER IN INDIA

India has a tremendous hydro potential.The Himalayas spreading across a length of about 3200 km and a width of 640 km has falls ranging from a few meters to a few thousand meters.The great Indus,the Ganga and the Brahmaputra rivers with their innumerable tributaries originating from Himalayas constitute about 70% of the country's hydro potential.The peninsular plateau,flanked on one side by the Eastern Ghats and on the other by the Western Ghats is a respectable of enormous hydro power.
As per the assessment of hydro potential carried out by the central Electricity Authority,our country's economically exploitable hydro potential of major and medium hydro schemes is 84044 MW at 60% load factor which will yield an annual energy generation of 442 billion units.With seasonal energy,the total energy,the total energy potential is assessed to be 600 billion units per year.The hydro  potential of 84044 MW at 60% load factor would be equivalent to an installed capacity of over 150,000 MW on the basis of probable load factor.
In addition to be above,56 sites have been identified for development of pumped storage schemes with total installed capacity of 93000 MW.
The potential of small schemes which can be developed on small rivers/hilly streams,canal head and canal drops is about 7000 MW in terms of installed capacity from about 1450 schemes.
As on 31.3.1996,the total hydro installed capacity in the capacity in the country was 20976 MW representing 14.84% of available hydro potential at 60% load factor.This included 1494 MW of pumped storage capacity from 7 pumped storage schemes. The share of hydro capacity in the total installed capacity of 83288 MW(from coal,gas,nuclear and hydro stations) was 25.19%.seventy seven (77) more schemes with an aggregate capacity of 17675 MW have been sanctioned by the Govt.and are at various stages of execution.These schemes account for 6.99% of available hydro potential at 60% load factor.The bulk of potential amounting to 78.17% thus remains to be developed.
