Hydroelectricity Micro and Pico Hydro
Hydroelectricity, Micro and Pico Hydro 
Classified as hydroelectric installations of less than 100KW capacity for Micro and less than 5KW capacity for Pico, these are installations in smaller rivers and streams. These can be either Dammed Reservoir type or Run of the River type but are usually the latter, especially for Pico installations.

These types of installations are an excellent method of providing energy to small communities in developing countries that do not have access to grid source power. Because the required output is small, the elevation drop of the water can be small, in some cases as little as one meter.
