The Minister of Mines and Energy, Alexandre Silveira, said this Wednesday (11) that the government is evaluating the resumption of daylight saving time this year.

The measure aims to balance energy security and maintain affordable tariffs, considering the increase in the use of thermoelectric plants to meet demand during peak hours, especially in the early evening, when solar energy generation is interrupted.

“Whenever there is any possibility that could point to a solution for the low tariffs and the security of the sector, it is important to evaluate it. Therefore, we are in the evaluation phase of daylight saving time”, he told journalists after participating in the event “The Role of Natural Gas and Biomethane in the Fair, Affordable and Sustainable Energy Transition”, held in Brasília, in MME.

According to Silveira, it is public knowledge that, although there are differences of opinion in society, the majority of the population s daylight saving time. In addition, the government needs to assess other impacts, such as the effect on the economy, since moving the clocks forward stimulates sectors such as tourism, bars and restaurants. “Daylight saving time is something that is on the table,” he said.

Daylight saving time in Brazil was a measure adopted to make better use of natural light and reduce electricity consumption during the months when the days are longer.

At that time, clocks were advanced by one hour, usually from October to February, in the states of the South, Southeast and Central-West regions. The main objective was to reduce the demand for electricity during peak hours, which occur in the early evening.

The measure was interrupted in 2019, when the suspension of daylight saving time was determined after studies indicated that its impact on energy savings had decreased, and also based on issues related to the well-being of the population. Daylight saving time in Brazil was first implemented on October 1, 1931, during the government of Getúlio Vargas.
