The National Electric Energy Agency (Aneel) announced that the tariff flag for April will be green, with no additional charges on electricity bills. The decision reflects satisfactory reservoir levels in hydroelectric plants due to March rains. The green flag has been in effect since January.
The Aneel announced on Friday (27) that the tariff flag for electricity consumers in Brazil will be green in April. This keeps electricity bills free of additional charges next month.
"With the rainfall volume observed in March, there are satisfactory levels in the reservoirs of hydroelectric plants, reflecting favorable energy generation," the agency stated in a note.
The green flag has been in effect since January this year, following favorable rains in the first quarter. The previous application was in April 2025. Since then, flags have alternated between yellow and red, levels 1 and 2.
The tariff flag system, which passes on variable generation costs to consumers monthly, marked ten years of implementation in 2025.
Green flag signals favorable generation conditions with no tariff increase. Yellow adds R$ 0.01885 per kWh; red level 1, R$ 0.04463 per kWh; and level 2, R$ 0.07877 per kWh.
