Aneel announced that the yellow tariff flag will be in effect in May, adding R$ 1.885 for every 100 kWh consumed on electricity bills. The change occurs due to reduced rainfall during the transition to the dry season, which decreases hydroelectric generation and requires greater activation of thermal power plants.
The yellow tariff flag represents less favorable conditions for electricity generation in Brazil. The change occurs due to reduced rainfall during the transition to the dry season, which decreases hydroelectric generation capacity and increases the need to activate more expensive thermoelectric plants.
The yellow tariff flag takes effect in May with an additional charge of R$ 1.885 for every 100 kWh consumed
The change occurs due to reduced rainfall during the transition to the dry period, affecting hydroelectric generation
With lower hydroelectric generation, there is greater need to activate thermal power plants, which have higher costs
From January to April 2026, the tariff flag remained green, with no additional charges
