Aneel confirms the return of the green tariff flag in October, eliminating extra charges on electricity bills. Improved water reservoir levels are allowing for financial relief for Brazilian consumers.
Brazilian consumers will experience financial relief starting in October. The National Electricity Agency (Aneel) announced the return of the green tariff flag for the entire national territory, meaning there will be no additional charges on electricity consumption next month.
The news comes after a period under the yellow tariff flag, which since May imposed an extra cost of R$ 1.885 per 100 kWh consumed. The official announcement was anticipated by the Minister of Mines and Energy, Alexandre Silveira, who attributed the positive scenario to the sector’s strategic planning and favorable weather conditions.
The Role of Rainfall and Sector Planning
The transition between dry and wet seasons, recently observed in the country’s main hydrographic basins, was decisive for this change. Increased rainfall in the South and Southeast regions allowed the reservoir levels of hydroelectric plants to stabilize, reducing pressure on the National Interconnected System (SIN).
With the hydrological recovery, the National System Operator (ONS) was able to reduce the dispatch of thermoelectric plants. Since the generation cost of these plants is considerably higher, their continuous use is passed directly on to consumer tariffs.
Alexandre Silveira stated:
The rainfall recorded this month, combined with good planning alongside all entities comprising the electricity sector, especially in light of El Niño, was essential for this.
Understanding the Tariff Flag System
Since its implementation in 2015, the tariff flag system has served as a transparent indicator of power generation conditions in Brazil. The mechanism reflects the real cost of electricity, balancing the availability of renewable resources with the need for more expensive complementary sources.
Aneel emphasizes that the green flag is not just a momentary benefit, but an important indicator that hydrological and dispatch conditions are balanced. For consumers, the measure reinforces the importance of energy efficiency, even in months without extra charges.
The expectation for the clean and renewable energy sector is that robust planning will continue to enable efficient reservoir management. With the end of the extra charge, the market projects a period of greater predictability for household budgets, now depending on continued rainfall during the summer hydrological cycle.
