In addition to the high tariffs, we are going to live with power cuts and we hope that we do not reach a blackout situation. Alert Adilson de Oliveira, professor at the Federal University of Rio de Janeiro (UFRJ)

Blackout? According to the sector's monitoring committee, although there has been an increase in rainfall in the main river basins that supply hydroelectric plants in Brazil, this increase has not yet been able to reverse the conditions of the reservoirs and the scarcity of water in the basins increases the risk of collapses. in power generation.

Between October and December, the National Interconnected System (SIN) recorded the second worst inflow – water reaching the hydroelectric reservoirs – in 90 years in the Southeast, Midwest and South regions.

To give you an idea of ​​how serious the situation is, one third of the reservoirs monitored by the National Electrical System Operator (ONS) have less than 20% of their total capacity.

Despite the worrying data, there are good prospects for rainfall in important basins, especially in the Southeast region, which concentrates most of the country's hydroelectric plants.

Due to expectations, the Electrical Sector Monitoring Committee (CMSE), linked to the Ministry of Mines and Energy, decided last Wednesday (6) to limit energy generation by thermal power plants to 16,5 average megawatts (average MW ) the import of energy.

Since the electrical energy produced by thermal plants is more expensive compared to the energy produced by hydroelectric plants, it weighs directly on the consumer's pocket.

At the end of last year, electricity bills were readjusted and consumers began to pay the highest rate (red flag level 2). It is now back to an alert status (yellow flag).

Adilson de Oliveira, professor at the Federal University of Rio de Janeiro (UFRJ), who during the reform of the electricity sector was a consultant for the Ministry of Mines and Energy, explains that the government needs to act quickly to avoid even more drastic problems.

“The account will increase, because we are going to work with the highest tariff flags. In March, it is likely to have another tariff. In addition to high tariffs, we will live with power cuts and we hope that we do not reach a blackout situation”.
