The number, almost R$ 1 trillion, is an estimate from a consumer entity, and the government counters by saying it ignores the benefits of the measures. More than half of the bill comes from a single and controversial energy auction. Amid the dispute of versions, the one who pays the bill is the consumer, who has already seen the tariff rise.
Decisions by the Lula government and Congress in the electricity sector are expected to add up to about R$ 985 billion in extra costs to Brazilians’ electricity bills by 2050. The amount, close to R$ 1 trillion, is an estimate by the National Front of Energy Consumers, and was contested by the Ministry of Mines and Energy, which considers the calculation methodology inadequate and states it is essential to consider the benefits of the policies adopted.
The survey was published by the newspaper Folha de S.Paulo on May 30, 2026, and refers to costs that are already contracted and will be incorporated into tariffs over the coming decades, without considering adjustments, inflation, or tariff flags. First of all, it is worth clarifying that this is a calculation by an entity that represents consumers, contested by the government, and not an official closed number, which makes the topic a subject of dispute between the two sides.
Where the bill of almost R$ 1 trillion comes from
To gauge the impact, the entity made some comparisons.
-
From street sweepers to doctors, various categories are seeking adjustments after the Senate approved the teachers’ minimum wage at R$ 5,130.63, and projects foresee amounts ranging from R$ 3,000 to R$ 13,000 depending on the profession and the required work schedule.

Appliance giant closes factory, lays off 1,700 employees after drop in sales, global inflation, and the rise of Asian competitors.

Petrobras puts R$ 70 billion on the table to create 25,000 jobs, operate platforms capable of producing 240,000 barrels per day, build 32 subsea wells, and a 134 km pipeline off the coast of Sergipe.

A BYD Dolphin driver can travel 1,500 km per month with recharging compensated by just 4 solar panels of 550 W, according to a calculation made in Recife that estimates a consumption of 181.5 kWh and a cost of R$ 180 at the outlet.
According to the National Front of Energy Consumers, the R$ 985 billion would be equivalent to six times the annual budget of Bolsa Família or five times that of Minha Casa, Minha Vida, and would be enough to distribute almost three minimum wages to each of the 213 million inhabitants of the country, if the amount were distributed.
The entity’s calculation gathers different measures.
Among the largest items are an energy auction from 2026, responsible for about R$ 515.7 billion, more than half of the total; the so-called “turtles” included in the offshore wind law, with R$ 197 billion; provisional measures that contracted thermal plants, with more than R$ 114 billion; the extension of incentives to renewable projects, with R$ 112.5 billion; and expenses related to the Itaipu plant, totaling R$ 21.1 billion, among others.
The electricity bill that has already been rising
The entity’s alert adds to a trend that consumers are already feeling in their wallets.
A middle-class family in São Paulo consuming about 200 kWh per month paid R$ 185 on their electricity bill in January 2023, a value that rose to R$ 220 in May 2026, an increase of 18.4%, above the inflation rate of 16.7% in the same period, according to the survey data.
The paradox pointed out by experts is that this price increase occurs even with the country producing a lot of clean and cheap energy.
Last year, residential electricity became the item with the greatest individual impact on the IPCA, the official inflation rate.
This combination of rising tariffs and excess generation fuels the debate about the need to reform the Brazilian electricity sector model.
The controversial auction that weighs on the bill
The item that weighs most in the estimate deserves an explanation, as it is technical.
The so-called Capacity Reserve Auction, the LRCap, is used to contract plants that remain available to ensure energy supply at times when solar and wind sources cannot meet demand, such as in the late afternoon when the sun sets and consumption increases, the so-called peak hours.
The need for this type of auction has grown with the advancement of renewable sources, which are intermittent, and with the explosion of solar panels on rooftops.
The problem, according to industry critics, was the way the 2026 auction was conducted: delayed by three years, with prices far above historical levels and the contracting of about 19 GW, equivalent to one and a half Itaipu, largely from more expensive and polluting thermal plants.
The auction generated questions from the Federal Court of Accounts and even legal disputes.
What critics of the model say
On one side of the debate are consumer entities and part of the industry.
According to the president of the Front, Luiz Eduardo Barata, “the sector is in disarray,” with the government and Congress taking disconnected actions to cater to one sector or another, and he advocates for a reform of the electric model starting in 2027, regardless of who wins the next election.
The criticism is shared by representatives of the private sector. Lucien Belmonte, spokesperson for the Union for Energy movement, which brings together more than 70 industrial sectors, states that the sector “has become a factory of add-ons.”
Entities such as Fiemg, the federation of industries of Minas Gerais, and FecomércioSP also advocate for a more considered analysis, warning that energy is increasingly weighing on the costs of companies, especially small and medium-sized businesses.
The government’s response
It is essential, for the balance of the matter, to record the version of the other side.
The Ministry of Mines and Energy did not question the value of the increase, but considers the methodology that attributes these costs to public policies “inadequate and superficial,” stating that it is essential to also consider the benefits, such as energy security, supply expansion, job creation, and investment attraction.
Regarding the most criticized auction, the ministry states that it was “the largest in the country’s history” and that the contract cost was five times lower than a similar auction in 2021, from the previous government, with an estimated saving of up to R$ 94 billion.
This point, however, is contested by the sector, which calculates, adjusted for inflation, that the 2026 auction was more expensive than the 2021 one.
The MME also cites reforms it approved and problems it claims to have inherited and resolved, such as the renegotiation of contracts from the previous government.
Why this affects your pocket
In the end, it is the consumer who is at the center of this tug of war.
Regardless of who is right in the debate over the methodology, the fact is that the electricity bill has a huge impact on family budgets and company costs, and any structural increase in tariffs directly reflects on the price of everything we consume, from food to services.
The episode exposes a deeper debate about the future of the Brazilian electric sector, which is undergoing a transition with the advancement of renewables and needs to balance clean generation, supply security, and affordable cost.
It is a technical topic, but one that directly affects the lives of all Brazilians, and it tends to gain even more space in public debate, including in elections, in the coming years.
The estimate of R$ 985 billion in extra costs on the electricity bill by 2050 has raised an important alert about the direction of the electric sector, even though the number is a projection from a consumer entity, contested by the government.
On one side, critics point to disconnected and expensive decisions; on the other, the Ministry argues that the measures bring benefits and security to the system.
Between the two versions, it is clear that the Brazilian electric model faces real challenges of cost and organization, in a debate that goes far beyond politics and reaches the bill that every Brazilian pays at the end of the month.
And you, have you felt the weight of the electricity bill on your budget? Do you believe that the Brazilian electric sector needs urgent reform, or do you agree with the government that the measures bring benefits?
