The month of September started with the more expensive electricity bill for Brazilian consumers, with the activation of the tariff flagária red on level 2 authorized by ANEEL (National Electric Energy Agency).
The forecast of lack of rain and Dry weather with high temperatures motivated the activation of thermal power plants, increasing the costs of operating the electrical system.
With forecast of below average rainfall nthe next month, the volume of water in the reservoirs of the country's hydroelectric plants as well should be about 50% below average.
The announcement of change in the flag signals higher costs for generating electricity, with an addition of R$ 7,87 for every 100 kWh consumed.
This is first time in three years that the red flag level 2 is activated (the last one was in August 2021).
In the past two years, the Brazil came from a sequence of green flags started in April 2022 and interrupted only in July 2024 with a yellow flag, followed again by another green flag in August.
“This scenario of scarcity of rain, combined with the month with temperatures above the historical average across the country, means that thermoelectric plants, with more expensive energy than hydroelectric plants, will start to operate more,” explained the ANEEL.
Tariff flag
created by ANEEL in 2015, the tariff flag system is a mechanism that applies an additional charge to consumers' electricity bills whenever there is an increase in the cost of energy production in the country depending on the availability of water resources.
As green, yellow or red colors (on levels 1 and 2) indicate whether energy will cost more or less depending on the generation conditions, with the red flag being the one with the highest cost, and the green flag being the only one with no extra cost.
“The flags allow consumers to play a more active role in defining their energy bill. By knowing the additional amount before the start of the month, they can adapt their consumption to help reduce the amount of the bill,” according to ANEEL.
“With the activation of the red flag level 2, vigilance regarding the responsible use of electricity is essential. The guidance is to use energy consciously and avoid waste,” highlighted the Agency.

Drought, who is to blame? Deforestation, riparian forests, and springs have been cut down. There is a lack of water at the 11.35 GW Belo Monte hydroelectric plant (18 turbines, only 1/2 of which is operating, less than 3% of its capacity). This is because the headwaters and basin of the Xingu River have deteriorated over the last 35 years. Even so, the Belo Monte hydroelectric plant would not work, except for EPE, which has been doing the trick with a run-of-river project. We have spent 40 billion for nothing. We have failed to build other more viable hydroelectric plants, to invest in substations and transmission lines (which are currently lacking to expand solar power). And we are doing yet another trick: the belief that solar power will solve the problem, and with batteries, a mindless marketing strategy. Without constant, intermittent power does not provide enough power and there is no balance. There is no magic. Urgent strategic actions are needed: Forest Regeneration and Recovery of Riparian Forests and Springs. Brazil is being taken over by marketers and has been without a strategy for over 50 years!
In 2021, the culprit was Bolsonaro. Because now any inference against Lula is unacceptable. Especially because the consumption of solar energy has increased sharply in recent years, mostly due to private and individual investments made in this area.
