Reassessment of irrigation potential for micro Hydro Power Generation

Hydro Power Generation projects are generally viewed as constructing large dams and reservoirs but available new research and engineering techniques have helped Hydro Power generation without large dams and without large reservoirs. In India, we have several water installations, irrigation dams, canals, streams or running rivers not tapped to generate power. In these cases the existing system and facilities can help in generating power with less investment and time. This area is yet unexplored. Harnessing a stream for hydroelectric power is a major undertaking. Careful planning is necessary for a successful and economical power plant. In this paper basic criteria for fixing the Plant capacity and various aspects related to planning are mentioned. Various basic design aspects, formulae and methods for deciding penstock, turbine, generator etc. are presented. The construction methodology and economics of Hydro power plant is well discussed. An example of Purna irrigation project is presented for possible development of micro hydro power plant. In this project all existing facilities of irrigation project are used. The canal water flowing is being used to generate hydro power. This paper can be well utilized by beginners for planning and irrigating land in and around rural areas and the most important aspect of financial planning and cost estimation can be done.
