 Power demand and possibilities of productive end use is to be accessed during feasibility studies. The primary use of micro-hydropower in the rural context of the country is usually for household lighting. In order to optimise the use and financial viability of the micro-hydropower plant, the installed capacity should be governed by household demand.
 Productive usage of electricity ideally complement the lighting use. Machinery that can be operated during the non - lighting hours, increases efficiency. The total capacity of productive uses under operation should be limited to the installed capacity, which is governed by the lighting demand. However, other approaches to sizing the plant capacity may also be proposed, provided that the financial viability can be demonstrated
 Usually demand grows over time. New households will be connected and new appliances used (radio, TV, stoves...). The available upper level of available power is defined by site conditions. Sizing of an mhp is also a question of available financial resources.
 To access the power requirements, the number of beneficiary households and their average power demand is to be determined. This is optimally done in discussions with the community. Make clear that more power in household connections will increase the price (= higher tariffs). Identify and encourage productive usage of electricity. Check marketability and feasibility of potential ideas. Thus may create additional income to the community. Identify time periods of potential machinery used. The prospective entrepreneurs willing to install the various end uses should be identified at the feasibility stage in detail.
