Micro-hydro electric plants are technologies that are appropriate for the provision of electricity where the demand for power is relative low (e.g. below 100 kW) and a constant flow of running water is available . This is often the case in villages or industries located in rural regions. Micro-hydro projects are commonly designed in "run-of-river" schemes, i.e. configurations where only part of the water flow of a stream or river is deviated to drive the hydroelectric units.
