One of the consequences of the severe economic crisis which has affected Brazil in the past years has been a substantial reduction in the available resources for power system investments. If budget is constrained below the ideal investment level, the problem of defining which generation and/or transmission investments should be postponed becomes very important. The objective of this paper is to describe a methodology for identifying which subset of transmission investments in a given expansion plan can be postponed in order to meet a preestablished budget constraint with the least possible impact on system performance. The methodology is based on the ranking of scheduled reinforcements by a cost/benefit index. The cost corresponds to the deterioration of operating conditions (e.g. increased risk of load curtailment) if the equipment is postponed.
