Aneel (National Electric Energy Agency) will apply the green flag on electricity bills in January. Thus, the year will start without additional costs on energy consumption.
According to the agency, precipitation remains below the historical average. However, in November and December, the country maintained the volume of precipitation and the level of hydroelectric reservoirs.
“In January 2026, it will not be necessary to ship thermoelectric plants in the same quantity as the previous month, which avoids charging additional costs,” specifies the municipality, in a note.
The system of tariff indicators on the electricity bill, which allows consumers to pass on the highest energy production costs in the country on a monthly basis, completed ten years of implementation in 2025.
This mechanism means that higher prices for energy production, especially due to the smaller volume of water in hydroelectric plants, are transmitted more immediately to families, so that they, informed of the higher cost, consume more consciously.
Previously, the transfer took place with a delay in the annual adjustment of tariffs – which could, without moderation in energy consumption, further boost the settlement of accounts.
The person responsible for choosing the monthly rate flag is Aneel. A charge is applied depending on the color (green, yellow, red level 1 or red level 2).
The definition uses different variables, the main one being the PLD (Difference Settlement Price) – an indicator that takes into account the value of energy production and is mainly influenced by the state of hydroelectric reservoirs and the resulting need to activate thermoelectric plants (i.e. less water means more costs).

- Green flag: favorable conditions for energy production. The price is not subject to any increase
- Yellow flag: less favorable generation conditions. The tariff increases by R$0.01885 for each kilowatt hour (kWh) consumed
- Red Flag – Level 1: more expensive production conditions. The tariff increases by R$0.04463 for each kilowatt hour consumed
- Red Flag – Level 2: even more costly production conditions. The tariff increases by R$0.07877 for each kilowatt hour consumed
