Flow is the other factor contributing to power production. It is usually limited by the size of the creek. The amount of electricity produced is directly related to the head and flow. If the head or flow is increased the power output increases proportionally. Many micro hydro systems can utilize the existing pipe used by a gravity fed water system.
Many factors work together to make a successful micro hydro site.
In order to have optimal performance your equipment must neither be too big nor too small. A turbine can be up to a couple of kilometers away from where the power is being used and still be cost effective. It is far cheaper to run wire lines than it is to extend the pipe length.
