Metering Aggregation in the Context of Full Opening of Power Markets: A Case Study

Energy markets are going through an unprecedented revolution, motivated by two factors: i) the increasing participation of renewable power in the electrical matrix and ii) the empowerment that the retail end-user is acquiring, including aspects such as distributed energy resources, and how the electrical matrix itself expands. In this context, energy markets must be flexible and enhanced, to guarantee that these two aspects can be fully integrated in the technical and regulatory framework. The context of the Brazilian power market is no different, and the main point that is currently on the agenda is how the transition to a full opened energy market can be done in an organized and sustainable way. Related to that, there are several aspects to be enhanced on the Brazilian power market design, but this paper focus on the aspects of the metering services. The objective of this paper is to present the state of the art on metering services, considering selected energy markets, and to propose a regulatory roadmap and market design approach that can be coupled to the Brazilian power market design so that the opening of the energy market can be implemented.
