RESUMO:

This paper aims to propose a fair efficiency evaluation model for electric power transmission in Brazil. The attention to this segment is mainly due to its participation in the greater part of the costs involved to define the value of the electric energy tariff and to the great territorial extension that, together with the regional and climatic divergences, make the process delicate. The power transmission system in Brazil, under the responsibility of the National Electric Energy Agency (ANEEL), adopts the revenue-cap (RC) model for incentive-based regulation. For this, among other factors, an efficiency analysis is performed through Data Envelopment Analysis (DEA). The systematic search and analysis of previous studies revealed that DEA applications, and adjacent models, in the transmission segment is still low, and the network modelling is the most used in addressing the problem. Thus, the evaluation model that this research adopts is the two-stage DEA network, in which the set of variables is responsible for explaining operational efficiency (stage 1) and financial (stage 2). The calculation is based on the centralized multiplicative method, allied to the Nash bargain game. The game theory approach aims at eliminating possible flexibilities and uncertainties inherent in network models, guaranteeing the uniqueness of optimum efficiency per stage. A two-dimensional representation of the results is also performed, in order to graphically observe the behaviour of the DMUs in front of the efficiency frontiers. It was found that the main problem of the companies under analysis is in the financial field. The graphical analysis, together with the performance indexes obtained, allows the transmitters to establish tactical guidelines that benefit them, as well as the regulatory agency and, consequently, the consumer society in general.
