The paper shows the application of Multiobjective Linear Programming with regard to the long-term planning of expanding the generation of electricity in Brazil. In order to apply linear multiobjective programming better in the context of powerful hydroelectric systems as has been occurring in Brazil, an approach is explored and a procedure considered which will allow the optimal composition of hydro-thermal systems to be found for supplying the electric energy requirements projected, for the future, which will benefit favorable flows and the greater probability of this occurring. However, at the same time there is a need to adopt protective measures against a period of reduced out-flow due to the use of thermo-electricity stations, for security and economic reasons. The results of this paper lead to the conclusion that the methodology of linear multiobjective programming has a wide field of application in the context of the new institutional model for the Brazilian electricity sector, in which the planning of expansion to be projected by the federal government, will, of course, be the focus of natural conflicting pressures from different agents and have multiple objectives to consider.
