A site specific, evaluation technique is being studied to examine hydropower potential based on an operations research approach for micro- and mini-hydropower systems under established guidelines of optimal pondages and objectives for two selected stream sites on the island of Kauai. Preliminary results of the study lead to the conclusions that a conduit type hydropower system with sizable storage capacity appears economically feasible for the two sites considered. But caution should be exercised in the interpretation of the results as the economic feasibility of the modified conduit type hydropower operation is highly sensitive to capital cost functions, operation and maintenance costs, as well as scheduled equipment life and interest rates that influence the present worth factor.
