Abstract
A preliminary estimate of hydropower production feasibility was made
for twenty-one existing dam sites in the State of Minnesota. The purpose
of the preliminary analysis was to determine whether a comprehensive feasibility
study is justified for the site. The expected annual energy production
and initial project cost were estimated for each site. Initial cost
estimates include turbine, generator, transmission line, and other electromechanical
features as well as the civil features of hydropower retrofitting.
Initial cost does not include dam rehabilitation, since the required information
is not available for 19 of the 21 sites. The "relative cost" of the project
was defined as the initial cost divided by the annual energy production, and
was calculated for each site. The relative cost and general curves for payback
period were used to estimate hydropower feasibility at each site. The
results of the preliminary analysis are: 5 sites have good or very good
hydropower feasibility, 6 sites are marginal, and 10 sites have poor hydropower
feasibility. Estimates of the cost of a comprehensive feasibility
study are included for each site.
