Nowadays hydroelectric plants are still the main sources of energy generation in Brazil. However, there is a lack of information regarding the efficiency of the decision to implement hydroelectric projects. Thus, the purpose of this work is to verify if the implementation of a run-of-the-river hydroelectric plant, with lower power generation capacity, is efficient in terms of economics and environmental impact, in comparison with a hydroelectric plant with water storage, in a similar stretch of water body, using the principles of cost-effectiveness analysis. The analyzed projects will be hydroelectric power plant (HPP) Garibaldi and HPP São Roque. The first hydroelectric plant with an installed capacity of 192 MW, against 142 MW of the second one. The financial costs incurred will be construction, operation, maintenance, population relocation, financial compensation to city counties and environmental costs. Through a comparative analysis between the hydroelectric plants selected made it possible to determine their cost-effectiveness index, and define trough the parameters which one of them affect the environment the least. The results showed that the HPP Garibaldi is more cost-effective with a cost-effectiveness index of 19,82 R$/MWh, compared to the generation by the São Roque HPP, with an index of 28,32 R$/MW. Thus, it is recommended that the decision to implement energy generation projects consider the mechanisms for including environmental costs, not only addressing financial costs in the assessments.
