Costs depend on size of potential site. They usually range from 2000 - 5000 USD/kW
Ideally flow measurements should be taken over several years to ensure safe data. A must is the measurement of the minimal flow during dry season. From there on a mhp plant can be installed within one year. Accessibility of remote location, delivery times for turbine and generator and social setup usually take longer than estimated.
