Comparative study between small-hydro-electric power plants (up to 10 MW capacity) and micro-hydro-electric power plants (up to 100 KW capacity) reveals that the former one is more capital intensive and involves major political decisions causing difficulties in different implementation phases. On the other hand micro-hydro-electric power plants are low cost, small sized and can be installed to serve a small community making its implementation more appropriate in the sociopolitical context.
