Principais causas de interrupções de fornecimento de energia elétrica na Bahia

Abstract

The availability of electricity is crucial for the progress and well-being of society. In this regard, electric power distributors have the main goal of ensuring a reliable, highquality, and uninterrupted service. It is essential for these companies to thoroughly examine the main reasons behind power outages in the electrical grid in order to implement preventive measures and strengthen the power infrastructure. This knowledge enables precise and efficient actions to avoid disruptions in the power supply, improve quality indicators, and prevent penalties and sanctions imposed by ANEEL (Brazilian Electricity Regulatory Agency). Therefore, the present research aims to analyze the electricity distribution service in the state of Bahia, verifying compliance with regulatory limits of DEC (Duration of Interruptions per Consumer) and FEC (Frequency of Interruptions per Consumer), as well as identifying the primary causes of supply interruptions throughout the months from 2020 to 2022. By utilizing publicly available databases provided by ANEEL, it was possible to conduct analyses of supply quality indicators by comparing annual and monthly values during this three-year period, establishing relationships between the causes and evaluating their impacts on the operation of the electricity distribution in the state. The analyses revealed that a significant portion of interruptions are related to environmental factors and natural phenomena, as well as equipment failures, and a seasonal pattern of outages was observed, showing similar behavior across the months in the three analyzed years
