Eficiência do setor de energia elétrica: análise das contribuições obtidas em audiências públicas relacionadas ao método de benchmarking dos segmentos de transmissão e distribuição. Orientadora: Dra.

Dissertação (Mestrado em Engenharia de Produção) - Centro de Tecnologia, Universidade Federal do Rio Grande do Norte, Natal, 2021.https://repositorio.ufrn.br/handle/123456789/58272In view of various contractual clauses, the economic regulation of the electricity sector guarantees to the electricity transmission and distribution concession contracts incentives for productivity gains based on the definition of the ceiling revenue and maximum price. In this sense, the National Electric Energy Agency - ANEEL adopts the Data Envelopment Analysis (DEA) technique with non-decreasing returns to scale to define efficient operating costs, which makes it a necessary step in this type of regulation. However, the perspectives of the indicators (variables), for example, still present difficulties in meeting the strategic needs of their stakeholders. Therefore, this work aims to analyze the contributions obtained in Public Hearings promoted by ANEEL from the proposition of a DEA efficiency assessment scenario for electricity transmission and distribution companies in Brazil. The present study consists of chronologically analyzing the benchmark evaluation models adopted by the regulatory body, intending to capture proposals and positions of companies and those associated with the sector. The sample used includes 43 transmission companies and 39 distributors in the segment. This delimitation was based on two criteria: 1) participation of companies in the 4th Periodic Tariff Review Cycle, due to future comparability of results, and also for 2) having an active service provision concession contract. A mapping was carried out in the literature and in the Public Hearings for the selection of variable groupings, which allows the proposition of scenarios for the execution of the DEA model. The results indicate that the unilateral claims of sector agents for the benchmarking models adopted by ANEEL can negatively interfere in the measurement of efficient operating costs, since there is a coexistence relationship between the variables and interactions between decision-making units of the model. This research is justified by the current search of the electric energy market for improvements in the evaluation models of efficient operating costs and in productivity gains to be shared with the users of the electric system.Acesso AbertoDEA-NDRSRegulaçãoSetor de energia elétricamasterThesisCNPQ::ENGENHARIAS::ENGENHARIA DE PRODUCAO
