The Brazilian electricity market architecture: An analysis of instruments and misalignments

Abstract

Brazil's current electricity market design heavily relies on auctions, long-term contracts, and central coordination mechanisms. Combining these instruments has proved to be effective in ensuring resource adequacy, a key policy objective. However, the implications of the dominance of the centrally coordinated auctions for long-term contracts are worth examining. This paper argues that the current market architecture may not represent the optimum long-term solution for a sustainable market as it ignores consumer preferences to drive investment decisions, transfers risks to consumers, has made the short-term market less relevant, and suffers from regulatory and design complexities.
