The growing technological development has significantly changed the consumption habits of the population, such as the greater insertion of artificial conditioning equipment and distributed generation, in addition to the implementation of the new tariff regime, the White Tariff, which is characterized as a mechanism of cargo management by the demand, whose adoption predicts changes in consumption habits. This study aims to evaluate the impact of the insertion of these new technologies and the new tariff regime on residential energy consumption in the national territory, and evaluate if the White Tariff in the proposed cases fulfills its purpose. The computational simulation in the EnergyPlus program 8.7, load curves for three locations, Bento Gonçalves, São Paulo and Belém, based on lifestyles defined from bibliographic sources, were estimated and the latter were calibrated with reference data and after applying the electricity costs of the Conventional and White tariff regimes. It was possible to verify that the differences of consumption between Traditional and Contemporary concentrate more on the end uses of Leisure, Lighting and General Services. While differences between localities focus on environmental comfort, water heating and food preservation due to climatic conditions. The results showed how the climate impacts the benefits of choosing the tariff modality. In Bento Gonçalves and São Paulo, the adoption of a photovoltaic system changed the benefits due to the generation of energy combined with the replacement of the electric shower. Moreover, the demand for energy for environmental conditioning has determined the feasibility of adopting the White Tariff in localities, mainly where this use shows its peak precisely at peak times, as in the cases of Belém, thus making the regime change unfeasible in this case, without compromising user comfort.
