This work proposes a linear disjunctive multiperiod optimization model for planning investments in energy sources considering two objectives, one economical (maximization of the net present value), and the other environmental (minimization of greenhouse gas emissions - GHG). The general goal of this approach is to provide an analysis tool for energy decision makers, for planning investment energy sources considering different scenarios in the GHG emanation. The decisions variables of the model are the investments needed in money, capacity and time in order to satisfy 100% of the energy market for Argentina from period 2010-2030. Two models are proposed, the first one considers the total amount of GHG released in the horizon time; and the other evaluates the amount of GHG released year by year. Twenty scenarios are evaluated with both models. The results obtained are presented, which show the trade-offs between both objectives.
