Ítem Análisis del comportamiento de los clientes frente al esquema de servicios públicos de Energía Prepago: El Caso de Empresas Públicas de Medellín.(Universidad EAFIT, 2018) Franco Acevedo, Jamer Arturo; García Rendón, Jhon Jairo; Gallego Acevedo, Juan MiguelRegulation rules between consumers and companies in Colombia, allow different payment schemes. The difficulty that many users face to pay their utility leads to suspension of service or disengagement by companies. Empresas Públicas de Medellin-EPM- designed the Prepaid Energy program, aimed at lowincome consumer or informal workers using devices that include new consumption measuring technologies. This paper analyzes similar programs in other companies that provide energy service. In addition, it deepens in the EPM experience, through ten years of the program, considering its beginnings and present state. The article deals with the study of the behavior in energy consumption, focusing mainly in stratums 1, 2 and 3. As the new program lets to better access of information through the prepaid meter and consumption control, making charges that adjust to the level of household income. Consumer benefit from a reduction in the risk of disconnection and have an alternative to repay the debt, allocating 10% of each fee for this purpose. The characteristics of the prepaid energy program of EPM are similar to those adopted in the United States and England. It seeks an alternative way for paying for energy consumption. Adjusting the payment to the income levels of users and letting the user to have control over their consumption avoiding the accumulation of delinquent accounts. Other systems such as those implemented in Brazil and South Africa have the purpose of expanding coverage in isolate areas and reducing operating costs in the delivery of invoices.Ítem Análisis sectorial de consumo de la electricidad durante la pandemia en Colombia(Universidad EAFIT, 2021) Arango Restrepo, Luis José; Rey Londoño, Felipe; García Rendón, Jhon JairoÍtem Efectos de los ataques terroristas sobre la demanda no atendida no programada de energía : evidencia empírica de los efectos del cese al fuego y firma del acuerdo de paz(Universidad EAFIT, 2022) Santamaría Vásquez, Isabella; Ramos Mosquera, Zwei Armando; Bohórquez Correa, SantiagoThe present investigation analyzes the evolution of terrorist attacks against the electrical power towers in Colombia and its effect on households due to unattended demand during the second decade of the 21st century and its change due to the ceasefire and the signing of a peace agreement. Annual data between 1990 and 2020 are used to show descriptive evidence and monthly panel data between 2008 and 2020 to make econometric estimates. Significant evidence is found to affirm that after the signing of the peace agreement with the FARC, there is a lower unscheduled unattended demand, which contributes to a better quality of life for society.Ítem Modelización de la demanda de energía eléctrica: más allá de la normalidad(Universidad EAFIT, 2019-06-04) Rendón, Juan F.; Trespalacios, Alfredo; Cortés, Lina M.; Villada, Hernán D.; lcortesd@eafit.edu.coThe main characteristic that differentiates electricity markets from other markets corresponds to the need to produce energy at the same time it is consumed, to such an extent that in real time the systems must maintain a perfect balance: at each moment the demand for electrical energy is equal to its generation. This characteristic prevents, for example, intertemporal arbitrage by those who carry out transactions in this market. In this regard, when modelling demand, it is common to find econometric analyzes that consider the assumption of normality; however, this assumption may ignore, a priori, an eventual presence of bias, kurtosis or higher order moments in this variable. In this paper, the Semi-Nonparametric approach (SNP) is studied to describe the demand for electricity in Colombia and the residuals of an ARIMA process. We propose the selection of probability density functions in terms of a finite Gram-Charlier expansion adjusted by the criterion of maximum likelihood. As a case study, the demand for electrical energy in the Colombian market is considered. As a result, it is found that the SNP type distribution achieves better adjustment than the normal distribution for some transformations of the electrical energy demand where it can be required more than four moments to represent this variable.
