The MME (Ministry of Mines and Energy) opened a public consultation this Monday (27) to review the rules for exporting electricity to Argentina and Uruguay.
The proposal aims to improve water use in the reservoirs of the South and make the system's operation more efficient. Contributions can be submitted for 45 days.
According to Ordinance No. 918/2026, the idea is to adjust the rules for exporting energy generated by hydroelectric plants operated by the ONS (National System Operator).
This energy is the kind that, at certain times, cannot be used in Brazil or sent to other regions.
The proposal divides exports into two categories:
- Ordinary turbine spilled energy (EVT-O): immediate surplus that would otherwise be wasted;
- Anticipated turbine spilled energy (EVT-A): energy that may be surplus in the future, based on operating forecasts.
The text emphasizes that exports cannot compromise the security of the National Interconnected System.
No prior contract will be required for exporting, and there will be no financial compensation in case of interruption.
In the case of EVT-A, exports will be made from plants in the South, considering two periods:
- June to November, when there is less rain in the North;
- From December to May, the rainy season in the North, is when the goal is to replenish the reservoirs in the South.
This replenishment should occur with energy generated in the North that cannot be used in other regions.
If there is a risk to the system, the ONS (National System Operator) may activate thermoelectric power plants, even outside the order of lowest cost, prioritizing service to the South.
Finally, any profits from the export of EVT-A will be divided among the hydroelectric plants that adhere to the model.
