Long-term planning to meet the growth of electricity demand in a country or region is a decision of strategic importance that should aim at maximizing the benefits provided and at minimizing negative impacts on the environment and society. In this sense, the objective of this study is to develop a methodology to determine the most suitable electric energy matrix of a country, that is, the best combination for the use of electricity generation sources. Thus, a multiobjective linear programming model is proposed to calculate the amount of energy that must be generated by each source available in the country, considering its internal demand and capacity constraints. Then the model was applied in a case study in Brazil for the years 2015, 2020 and 2030. The proposed model proved to be a useful tool to assist in the analysis and planning of the use, and possible extension, of the generation capacity of each electric power source of a given country.
