Abstract: Running down the fossil fuel and the incapability to meet up the increasing demand of electricity is some problem for the economic development of Bangladesh. The country is getting trouble due to carbon emission of developed country. Bangladesh has several rivers and canals providing off- grid network. This paper focuses on the potential of micro-hydropower plant in Bangladesh. This paper also replicates on energy scenario of Bangladesh. To progress the economy of Bangladesh it is need to explore green energy providing good investigation on establishment of extensive micro-hydropower plant. The most likely sites for micro-hydropower have low head(less than 10m) that also has a regular disparity. Thus the selection of suitable turbine has a vital role on the sustainability of the project. The present potential sites are mentioned and means to identify new sites are outlined by performing hydrology studies, topographic studies, head calculations, turbine selection and so onward.

Keywords: Hydro Power, Micro Hydro, Mini Hydro, Crossflow Turbine, Propeller Turbine.
