Aneel approved on Wednesday (22) a series of tariff adjustments that will increase the electricity bill for about 22 million consumers in São Paulo, Bahia, Ceará, Mato Grosso, Mato Grosso do Sul, Rio Grande do Norte, and Sergipe. The largest impact for residences was registered at CPFL Santa Cruz, with an increase of 17.86%, driven by the rise in transmission costs and sectorial charges.
The electricity bill will become more expensive for millions of Brazilians starting this week. Aneel approved on Wednesday a series of adjustments and tariff revisions that affect consumers in seven states, with increases varying according to the distributor and customer profile. The indices were mainly driven by the rise in transmission costs, the increase in the purchase price of energy, and the growth of sectorial charges that make up the tariff paid by the final consumer.
The scenario marks the return of tariff pressures after 2025, a year that recorded reductions or moderate increases in various concessions. The affected states are São Paulo, Bahia, Ceará, Mato Grosso, Mato Grosso do Sul, Rio Grande do Norte, and Sergipe. The new values come into effect after the publication of the dispatch by Aneel and are already reflected in the upcoming bills. For residential consumers, the impact varies from 3.74% in Rio Grande do Norte to 17.86% in the service area of CPFL Santa Cruz, in São Paulo.
How much will the electricity bill increase in São Paulo
According to information released by the portal ndmais, São Paulo accounts for the largest adjustments approved by Aneel in this round. CPFL Paulista, based in Campinas, serves 5.12 million customers and had an average approved increase of 12.13%. For industry and companies connected at high voltage, the increase is 18.75%, while for residences and small businesses, the average increase is 9.25%. The numbers show that the productive sector will be the most affected by the tariff revision of Paulista.

CPFL Santa Cruz, which serves about 528,000 customers, showed the highest increase for residential consumers among all the distributors evaluated. The adjustment for low voltage was 17.86%, which means that a family that paid R$ 200 for the electricity bill will now pay approximately R$ 236 starting from the validity of the new tariffs. The overall average increase for Santa Cruz was 15.12%, driven by the same factors that pressured the other concessionaires.
The impact on the states of the Northeast and Central-West
In Bahia, Neoenergia Coelba serves 6.92 million consumer units and had an average adjustment of 5.85%. For residences, the increase will be 3.93%, one of the lowest among the affected states, although high voltage recorded an increase of 10.21%, putting pressure on industries and large commercial establishments. Ceará, with 4.11 million customers from Enel, will have an average increase of 5.78%, with 4.67% for low voltage and 9.61% for high.
In the Central-West, Energisa Mato Grosso, which serves 1.73 million consumers in Cuiabá and surrounding areas, had an average increase of 6.86%. Residences will see an increase of 5.27%, while the industry will face an adjustment of 10.42%. In Mato Grosso do Sul, Energisa in Campo Grande serves 1.17 million units and had a balanced increase: 12.39% for high voltage and 11.98% for low voltage, with an average of 12.11%.
Rio Grande do Norte and Sergipe complete the list of affected states
In Rio Grande do Norte, the 1.59 million customers of Neoenergia Cosern will have an average increase of 5.40%. For residences and small businesses, the impact will be 3.74%, the lowest among all states on the list. High voltage, however, will have a adjustment of 10.90%, showing that the pattern of greater pressure on the industrial sector is repeated in almost all concessions evaluated by Aneel.
In Sergipe, the 919 thousand consumers of Energisa will face an average increase of 6.86%. The industry will be the most affected, with an increase of 12.36%, while residential customers will have an adjustment of 5.24%. Although the percentage for residences is moderate compared to São Paulo, the impact is proportionally heavier in a state with lower average income, where the electric bill represents a larger share of the family budget.
What is behind the increases approved by Aneel
The adjustments are not arbitrary. Aneel follows a methodology that considers the real operating costs of the distributors, including the price of energy purchased in the regulated market, transmission costs, sectoral charges, and investments made in the distribution network. When these costs rise, the tariff is adjusted to maintain the economic-financial balance of the concessions, ensuring that companies continue to operate and invest in the expansion and maintenance of the electric system.
The problem for the consumer is that this logic does not always translate into a noticeable improvement in service. Blackouts, voltage drops, and delays in service continue to be frequent complaints in various concession areas, and the increase in the electric bill without a corresponding improvement in quality fuels dissatisfaction. Aneel states that the adjustments include components of mandatory investment that should result in improvements in the next tariff cycles.
Are you among the 22 million consumers who will pay more for their electricity bill, or do you live in a state that escaped this round of increases? Tell us in the comments how much you pay for energy and whether you think Aneel’s increases are justified given the quality of service you receive.
