Análise estatística dos impactos causados pela pandemia de COVID-19 no Setor Elétrico Brasileiro.

Abstract

In this paper it is presented a statistical analysis of the COVID-19 pandemic impacts in the brazilian electricity sector. To make this analysis, it was used official data from the Health Ministery of Brazil and from the Electrical System National Operator (ONS, abrev. in PT). The database of Charge per Hour (GWh), Storage Energy (GWh) and Marginal Operational Coast (R$/MWh) of the electricity sector and the new weekly cases of COVID-19 in Brazil were collected to be analyzed statistically, based on the Pearson correlation coefficient. The calculous was made in different time windows and with multiple variables, enabling the analasys of the electricity sector behavior during the COVID-19 pandemic. With this, it was observed that the impact of the pandemic had different characteristics along the time, having more influence in the charge in the beginning of the pandemic and falling along the period. This method of analysis offers a potential use to plan answers in case of another worldwide impact phenomenon.
