• Abstract:

  The goal of this work was to study the fluctuation of energy demand as a function of its price, in order to analyze the feasibility of migrating from the conventional energy tariff to the white tariff. To predict certain scenarios, the concepts of price-demand elasticity were used. The estimates of the price-demand oscillation were carried out after collecting energy consumption data in homes in different neighborhoods, therefore, different social classes, so a load curve was set up to analyze the consumption from time to time. The model's goodness of fit was evaluated through dispersion calculations and the correlation between observed values ​​in each unit and the estimates was verified. Considering that the correlation of price-demand elasticity in this case is unitary, therefore, the value oscillates proportionally to the demand, it was possible to conclude with this present study that, for certain social classes, it will be of little advantage to abandon the conventional tariff, as it is necessary that there is a drastic reduction in electricity consumption at peak hours. On the other hand, for other social classes, which naturally consume more energy, it is advantageous after a certain point to migrate from the conventional tariff to the white tariff.
