The harnessing of energy of the
falling water to provide mechanical power has been one of man's greatest
achievements. Water wheels providing mechanical power for grinding and water
pumping are still in common use.
The
industrial revolution created new requirements, which demanded larger power
generating capacities, which led to rapid improvement in the design of water
wheels, turbines and generators. The capacities of hydro power plants became
very large as electricity generation became common place by the end of 19th
century. The position has ultimately reached a stage where large-scale
hydroelectric plants contribute significantly to the State's and the National
energy demand. Unfortunately, every development has its cost and the cost of
exploiting hydro power is vigilance in ensuring the environment is not
irreparably damaged and the life of the river continues to flourish. This
demands considerable care and attention in planning.

The situation is different in
case of micro, mini or small hydro power projects. A micro, mini or small hydro power station can divert potential energy of the water, which would have
dissipated to no benefit in the natural flow along the watercourse. Mini, micro
and small hydro plants combine the advantages of large hydro plants on one hand
and decentralized power supply on the other. The disadvantages associated with
large hydro power plants, like high transmission costs, environmental issues
like submergence of forests and croplands, and displacement of families, are
not present in small plants.
Moreover, the harnessing of local resources like
small hydro resources, being of a decentralised nature, lends itself to
decentralised utilization, local implementation and management, making rural
development possible based on self-reliance and use of local natural resources.
With proper site selection, turbine sizing and commissioning it is very cost
effective when integrated with irrigation and water supply projects.
