Bandeira Tarifária Amarela em Maio: +R$1,885 por 100 kWh
Summary
ANEEL confirmed that the yellow tariff flag (Bandeira Amarela) will apply in May 2026, resulting in an additional charge of R$ 1.885 per 100 kWh consumed. This change follows four consecutive months (January–April 2026) of green flag status, which had reflected favorable hydroelectric generation conditions. The yellow flag was triggered by below-average rainfall during the transition from the wet to dry season, reducing reservoir levels and necessitating greater reliance on higher-cost thermoelectric power plants.
“Em consequência, os consumidores de energia elétrica terão custo adicional de R$ 1,885 a cada 100 kWh consumidos.”

What changed
ANEEL's monthly tariff flag system moved from green to yellow for May 2026, adding R$ 1.885 per 100 kWh to consumer electricity bills. The yellow flag reflects decreased rainfall during the transition from the rainy season to the dry season, which reduced hydroelectric generation capacity and required increased activation of more expensive thermoelectric plants. From January through April 2026, the green flag had been maintained, indicating favorable generation conditions.
Electricity consumers in Brazil should expect higher electricity costs in May 2026 due to this tariff adjustment. ANEEL advises consumers to adopt efficient energy consumption habits to minimize the financial impact and contribute to the sustainability of the electric sector.

BANDEIRA TARIFÁRIA
Bandeira tarifária para o mês de maio será amarela
Volume de chuvas na região dos reservatórios ficou abaixo da média Compartilhe: Publicado em 24/04/2026 18h02
A Agência Nacional de Energia Elétrica (ANEEL) confirmou nesta sexta-feira (24/4) que será amarela a bandeira tarifária no mês de maio. Em consequência, os consumidores de energia elétrica terão custo adicional de R$ 1,885 a cada 100 kWh consumidos. O anúncio ocorre devido à redução de chuvas na transição do período chuvoso para o seco, o que leva a uma geração hidrelétrica menor e ao acionamento de usinas termelétricas, com custo mais elevado.
De janeiro a abril deste ano, a bandeira tarifária permaneceu verde, refletindo as condições favoráveis de geração. Adotado pela ANEEL em 2015, o sistema de bandeiras tarifárias é uma ferramenta essencial de transparência, permitindo que os consumidores acompanhem, mês a mês, as condições de geração de energia no País.
Com o acionamento da bandeira amarela, a ANEEL reforça que os consumidores devem cultivar bons hábitos de consumo para evitar desperdícios e contribuir para a sustentabilidade do setor elétrico.
