Cost Estimates for Hydropower at Existing Dams

Abstract

Guidelines for quick and simple hydropower project cost estimates are developed for preliminary site assessments. The guidelines are based upon a concept which incorporates a single equation utilizing design power and head for total equipment cost and a “site factor” to determine total project cost. Total project cost is estimated by multiplying the equipment cost, obtained from the equation, and the site factor. Total project cost data from a number of hydropower projects are compiled to provide guidelines for choosing the site factor, which is shown to vary greatly, especially for micro
