Drought halts hydroelectric operations in the North region 

O ONS (National Electrical System Operator) reported, this Wednesday (4), that the Santo Antonio Hydroelectric Plant needed paralyze part of its generating units because of lack of rain which reaches the Madeira River region, between the states of Rondônia and Amazonas. 

Ao Canal Solar, the agency reported that 43 of the plant's 50 turbines are currently out of operation. In other words, only seven generating units are in full operation. 

A hydroelectric of Saint Anthony is one of the largest in Brazil, with an installed capacity of 3.568 MW, sufficient to supply up to 45 million people.

In a note, the Eletrobras, company that controls the enterprise, highlights that it was necessary to stop the generating units of the plant located on the left bank and in the bed of the Madeir Rivera, since the tables have reached operational limits.

“The maneuver allowed energy generation to be maintained concentrated in seven generating units located in Generator Group 1, on the right bank of the river, which are synchronized in the 500 kV sector of the plant,” says the statement. 

At the moment, with flows close to historical minimums (2.700 m³/s) and effective generation of approximately 490 MWm, the plant remains in operation without any forecast of a total shutdown of generation.

“However, as it is a run-of-river plant, which operates according to the hydrological behavior of the river, if there is a much greater decrease in flows, this measure may be necessary (complete shutdown of the plant)”, informs Eletrobras. 

Dry weather 

As reported by Canal Solar, Brazil will face a unprecedented heat wave in September, with record temperatures being recorded in several states, according to alerts issued this week by the country's main meteorological institutions. 

O inmet (National Institute of Meteorology) points out that temperatures are expected to be above average in much of the country, due to reduced rainfall, with the possibility of a few days of excessive heat.

O Weather, in turn, highlights that Brazil will experience one of the most intense heat waves ever recorded, while the MetSul Meteorology points out that the situation is highly dangerous and will require attention from authorities throughout Brazil.
