Brazil will face a heat waveunprecedented in September with record temperatures being recorded in several states, according to alerts issued by the country's main meteorological institutions.
Inmet (National Institute of Meteorology) points out that the t temperatures should be above averagein much of the country, due to reduced rainfall, with the possibility of a few days of excessive heat.
Climatempo, in turn, highlights that the Brazil will experience one of the most intense heat waves ever recorded, caused by a phenomenon known as a “heat dome”.
This phenomenon occurs when a high-pressure area forms over a large region, trapping hot air near the surface and preventing it from dissipating. This high-pressure area acts like a lid, increasing temperatures as the air is compressed and heated.
Already MetSul Meteorology informs that the The situation is highly dangerous and will require the attention of the authorities. “There will be several states where the heat will be very intense to extreme and accompanied by excessively dry air,” highlights the company.
As The most affected regions are expected to be the Center-West, the North and parts of the Southeast, with temperatures above 40ºC in many cities. Parts of the Northeast, such as inland areas of Maranhão and Piauí, should also suffer from excessive heat.
Energy consumption
Due to the heat wave, the ONS (National Electrical System Operator) designs a increase in energy consumption because of the greater number of ventilation and air conditioning equipment connected in homes and businesses.
The estimate is that the load demand in SIN (National Interconnected System) stay at the average of 77.432 MW, an increase of 0,3% compared to the same period in 2023, when consumption was already high (on average 77.200 MW) due to high temperatures in that month.
On September 25 and 26 of last year, the system recorded consumption of more than 96.000 MW at times.
More expensive electricity bill
To theconsumers who are concerned about the value of their electricity billand they would already spend more than normal because of the heat, news is not promising: September started with the more expensive bill due to the activation of the tariff flag red on level 2.
The announcement signals higher costs for the consumer's electricity bill, with an increase of R$ 7,87 for every 100 kWh consumed. The forecast of a lack of rain motivated the activation of thermal plants, increasing the costs of operating the electrical system.
In understanding the ABSOLAR (Brazilian Photovoltaic Solar Energy Association), the increase in electricity bill could be smaller no recurring cuts to the most competitive renewable plants and less taxes on batteries.
