Mini Hydro
Description of technology
What it is?
It is a proven Renewable Energy Technology used for producing electricty.

How does it work?
Kinetic energy of water is turned into mechanical energy by turbines which in turned is converted into electrical energy by a genereator.

Where it can be used?
High and medium altitude hills, rivers and streams, for supplying electricty to isolated settlements or for connection to the grid.

What expertise is required operating and maintaining?

• A trained operator for operating mechanical and electrical equipments.
• A manager for the overall management of the project e.g tariff collection, coordination with installer companies in case of breakdowns etc
Specific Features
Rural households generally use kerosene, and diesel for lighting, therefore availability of Micro Hydro plants replaces kerosene and diesel
