The impact on electricity demand and emissions due to the introduction of electric cars in the São Paulo Power System

Over the past years, the pursuit of using less polluting energy sources throughout society has been on the increase. In general, the transportation sector is responsible for most of the emissions of greenhouse gases. Therefore, in this article a methodological approach is applied in such a way that it is possible to quantify the impact of the penetration of electric vehicles vis-à-vis others that use different types of fuel (flexible fuel, for example). The study is conducted for a road modal in São Paulo, the main state in Brazil in terms of economy, energy and environment, taking into account only automobiles. A comparative analysis of forecasting scenarios until 2035 for various inputs of electric cars in the whole state fleet is presented, aiming to verify the susceptibility of the model suggested, upon the introduction of electric vehicles, taking into account also the electrical and environmental impacts related to it. The analysis was possible due to the use of a simulation tool, Long range Energy Alternatives Planning System (LEAP), which is an energy environmental model based on scenarios, allowing an integrated and reliable support to develop studies on integrated energy planning.
