HYDEL ENERGY

Water flowing in the rivers have kinetic energy. Once they are used to drive the turbine and produce electricity the power generated as Hydel Energy.

Power produced by the turbines depends on quantity of water flowing/minute and the head of water available.

Mostly river flows by melting glaciers on high mountains. Once the water start flowing in the valleys it changes its head very rapidly. this energy can be converted in to electrical energy.

two method are normally used

In case of Dams the water flow is restricted by making a huge storage device and the head of water is increased. the water then allowed to flow by means of gates and pass through the turbines. the head of reservoir Laval is maintained to provide uniform power. the water stored in peak season additionally used for irrigation purposes in dry seasons.

In run of river projects the water is diverted through the tunnels and once it gains the head allowed to fall and pass through the turbines and back to river. the water in these projects is continuously flowing and not being stored.

Geographical situation is paramount importance in choosing a suitable site for the hydro project and it evolves a very serious time and money consuming study.

Once a site is located further detailed feasibility study is required before proceeding any serious effort to start the work.

The feasibility study should include following field work.

1. Detailed Mapping of the area

2. Topographic study of the area

3. Seismic refraction study

4. River flow data

5. Weather data containing, Temperatures, pressures, rain humidity

6. Water sampling and testing

7. Environmental study

8. Social impact

9. Wild life and fishes study

10. Identification of stake holders of the area

11. Coring and getting samples of the soil at 50-200 meters depth

12. Laboratory testing of the cores samples

13. Tectonic study to evaluate earth quake dangers
