Electric load forecasting is known as one of the most important challenges in managing electrical supply and demand and has been widely studied. This forecast is an important work to increase the energy efficiency and reliability of the power system operation. It is possible to highlight that the element that determines short-term market prices and represents the foundation for the free energy market is the Settlement Price of Differences, commonly called PLD. In accordance with the proposal made by the Standing Committee for the Analysis of Methodologies and Computational Programs in the Electric Sector (CPAMP), as of January 2021, the Settlement Price of Differences must be calculated on an hourly basis. Due to this fact, this work aims to predict, through statistical models, new consumer load profiles, taking into account the recent pricing dynamics and the new necessity that need to be met. More specifically, this work will focus on the hourly load generation profile, as the introduction of hourly price requires that the daily load curves be accurately projected (24 hours ahead).
