Abstract

This paper investigates the performance of the Brazilian largest hydropower plants. This study covers 78% of the total installed capacity from hydros in the country, and considers indicators reflecting operational and maintenance costs as well as quality of service. The assessment was conducted using a new approach for the construction of composite indicators, based on a Directional Distance Function model. In a first moment, we assessed the hydropower plants allowing for complete flexibility in the definition of the weights, enabling the identification of under-performing plants and quantification of their potential for improvement. Next, we assessed the hydropower plants considering different perspectives regarding the importance attributed to each indicator. This allowed to reflect different points of view, focusing primarily on operation and maintenance costs or on quality issues. The results identify the hydropower plants that can be considered benchmarks in different scenarios, and allow testing the robustness of plants' classification as benchmarks in the unrestricted model.
