Daylight saving time
In effect since October 21, the daylight saving time aims to reduce the risk of problems with electricity supply at a time when the demand is growing due to high temperatures and industrial demands for Christmas. With natural light for a few hours more, the consumption is diluted from 6PM to 10PM, avoiding overloading the system, as advocates explain.
In the last decade, according to the Department of Mines and Energy, daylight saving time allowed an average reduction of 4.6% in energy demand during peak hours, from 6PM to 9PM. The government estimates that this year has saved about R$ 280 million, reducing the energy demand by 5% in these hours. In the previous edition, according to the Electric System National Operator (ONS), the country saved R$ 160 million.
