Artigo Effects of the COVID-19 pandemic on the Brazilian electricity consumption patterns(Wiley, 2020) Souza, Dyego Leandro Bezerra de; Carvalho, Monica; Delgado, Danielle Bandeira de Mello; Lima, Karollyne Marques de; Cancela, Marianna de Camargo; Siqueira, Camila Alves dos; https://orcid.org/0000-0001-8426-3120The implementation of mobility restrictions and home office schemes due tothe COVID-19 pandemic have influenced electricity consumption patterns andlevels. This study analyzes the effect of physical distancing measures regardingmobility on the energy consumption trends for the Brazilian energy systemand its subsystems (Northeast, North, South, and Southeast-Midwest). Trendswere evaluated by the Joinpoint software, and the analysis comprehended theperiod between January 1 and May 27, 2020. Daily load data was grouped intoweeks, with the calculation of weekly percentage changes considering a 95%confidence interval andp< 0.05. The weekly electricity loads were comparedin the periods before and after the isolation decrees were enforced in Brazil(March 15, 2020). Statistically significant decreases were observed in the levelsof electricity consumption, with trends represented by two joinpoints. Due tothe different profiles of consumption across the geographic regions, theresulting electricity dynamics were also different. This is the first study toemploy joinpoint analysis for the calculation of energy consumption trendsfocusing on the COVID-29 pandemic. Data presented herein is unique, in itsfocus on Brazil, which enables more accurate implications to be drawn for Bra-zilian policy makers
