RESUMO

In recent years, the electric power supply sector has undergone major structural changes in a variety of regions throughout the planet. These changes are due to restructuring processes taking place in the energy sector towards the increase of quality and efficiency. In Brazil, it was created agencies responsible for the sector, in order to foster and regulate those changes, either by means of creating instruments for promoting competition or by allowing private agents participation in the processes of generating, distributing and trading energy. In this context, it was created the Brazilian Electricity Regulatory Agency (ANEEL), responsible for binding rules to assure market competition in the electric power supply sector. Among the duties of the regulatory agency of the electric power supply sector in Brazil there is the periodical revision of energy prices. Such revisions involve estimating the X Factor applied to update prices so that gains in productivity are shared with consumers. To estimate the X Factor it is necessary to measure efficiency and, for this, two issues are important: the choices of benchmarks and of techniques for productivity measurement. This thesis proposes an approach to define frontier efficiency of electric power distribution utilities based on clustering homogeneous utilities using neural networks and estimating the frontiers through econometric techniques.
