Micro-hydro is a term used for the installation of power plants that use water energy. Whereas micro means small hydro means water. Generally it can be interpreted that the plant Micro Hydro Power (MHP) is a power plant with a small scale that utilize the flow of water as the power (resources) to drive the turbine, converts the potential energy of water into mechanical work, turning a turbine and generator to produce electrical power small scale , (Khairul Umri, 2009).
The size of the generated power to the MHP is highly dependent on the water flow and the potential energy of falling water. MHP is not the same as the Hydroelectric Power Plant (HEPP), although its main source of energy generated from water. One of the differences seen in the amount of power generated. In general, the MHP is only able to provide energy above 500 watts up to 2 MW, if the energy generated exceeds the already classified in hydroelectric power plants. This plant has several advantages, such as:
1. Environmentally friendly because it does not use fossil fuels.
2. Its natural resources are easily found so suitable for use in the long term.
3. Reliable Technology; The technology used is reliable and sturdy so as to beroprasi more than 15 years.
4. Sources of potential that is widely available in Indonesia.
5. Easy operation (IBEKA, 2003).
