This paper aims at comparing the national and international incentive policies in energy efficiency investment and presenting the main trends, measures adopted and economical and environmental results obtained, as well as possible improvements and expansions of these programs. This analysis is justified by the current moment, not only of the Brazilian Power Systems (SEB) but also of the global power systems with the constant increase of demand and depletion of natural resources implying in a need of a better use of them and of the power they generate, which directly affects the losses on the generation, transmission, distribution and consumption of energy, in addition to reducing the impacts on the environment. At last but not least, through this study it was possible to gleam not only at new possible ways for these programs, but also failures and inefficiencies that can be improved in the measures currently being used

The transmission system is responsible for connecting the power generators to consumers safely and reliably, its constant expansion is necessary to transport increasing amounts of electricity. In order to help the power systems engineers, an optimization tool for optimize the expansion of the transmission system was developed using the modeling method of the linearized load flow and genetic. This tool was designed to simulate the impact of different scenarios on the cost of transmission expansion. The proposed tool was used to simulate the effects of the presence of distributed generation in the expansion of a fictitious transmission system, where it was found a clear downward trend in investment required for the expansion of the transmission system taking account of increasing levels of distributed generation.
