摘要

Brazilian market structure is based on two markets operating together: the regulated market (RM) and the free market (FM), with RM being 76% of total demand.These two markets, even though operating together, have different regulatory rules, as well as different consumers’ profiles.In the RM, the fundamental instrument for generation expansion is the set of auctions to supply energy to captive consumers through new generation, where generator candidates compete among them for regulated contracts with the distribution companies. The outputs of those auctions show the long term prices of energy, taking into account that the contracts are signed for twenty (20) years, in general.On the other side, are the free consumers, who have a clear preference for short term contracts, so that they can explore periods of low spot prices and favorable picture in the offer x demand scenario. Being predominantly hydro, the Brazilian system shows several periods of low spot prices and few periods of extremely high spot prices, depending on hydrological conditions.This paper will present a brief analysis of the main cornerstones of such commercial environments, will provide some examples of markets behavior and make some suggestions for improvements.
