Brazilian households and companies may face almost R$1 trillion in additional electricity costs over the next quarter-century, according to a survey by the National Front of Energy Consumers cited by Folha de S.Paulo.
The group estimates that decisions made during President Luiz Inácio Lula da Silva’s third term and the current Congress have already contracted R$985 billion in extra costs through 2050 — roughly USD 180 billion at recent rates. The Ministry of Mines and Energy said the methodology is “inadequate and superficial” because it does not account for benefits such as security of supply, new investment and modernization of the grid.
What Is Driving the Bill
The estimate includes costs tied to Itaipu, the giant binational hydroelectric plant shared by Brazil and Paraguay; extensions of subsidies for renewable-energy projects; and the contracting of backup power to cover periods when solar and wind generation cannot meet demand.
Brazil’s power system is under pressure from a paradox: the country has abundant cheap renewable generation, yet consumers are paying more. Folha reported that a middle-class family in São Paulo using about 200 kilowatt-hours a month paid R$185 for electricity in January 2023 and R$220 in May 2026, an 18.4% rise, slightly above accumulated inflation of 16.7% in the period.
The National Front argues that the sector lacks a coherent framework for the rapid shift toward intermittent energy. Rooftop solar capacity rose from 26 gigawatts in 2023 to 45 gigawatts last year, according to Folha. Brazil’s grid operator, known as ONS, can cut output from large solar and wind farms when supply exceeds demand, but it does not control generation from household panels.
The Capacity Auction Dispute
The largest single disputed item is the 2026 Capacity Reserve Auction, known in Brazil as LRCAP. The federal government’s Investment Partnerships Program said the auction contracted 18.977 gigawatts of capacity, including 16.7 gigawatts from thermoelectric plants and 2.5 gigawatts from hydroelectric expansions, with projected investment of R$64.5 billion.
The government described the auction as a way to strengthen the National Interconnected System during peak demand and renewable intermittency. It said the average price was R$2.33 million per megawatt per year, with a 5.52% discount from ceiling prices.
Critics say the design was costly and poorly timed. Folha reported that the auction alone may add R$546 billion to electricity bills, more than half of the total extra cost estimated by the consumer front. The Federal Public Prosecutor’s Office recommended suspending the homologation of the 2026 auctions, citing alleged irregularities and a potential cost of more than R$500 billion over 15 years.
According to the prosecutors, ceiling prices rose between 73% and 100% in less than 48 hours after private companies and trade groups asked for revisions. The office said the Energy Ministry and the state energy-planning agency accepted spreadsheets from interested companies without independent estimates. The recommendation also questioned the exclusion of cheaper alternatives such as large battery storage.
Congress and Subsidies
Congress has added another layer of cost through so-called jabutis — unrelated amendments inserted into bills already moving through Brazil’s legislature. Folha cited the offshore wind bill as the best-known case: it left the Senate focused on offshore wind rules, then gained provisions in the lower house extending subsidies and thermal-power obligations.
Lula vetoed parts of the bill after warnings about cost. Congress overturned the vetoes, creating an estimated R$197 billion charge over 25 years, according to Folha.
The Ministry of Mines and Energy rejects the portrayal of scattered measures. It says recent laws amount to one of Brazil’s most important electricity-sector reforms in years and argues that capacity contracting is essential for the expansion of renewables. The ministry also says it renegotiated emergency contracts from the previous administration and reduced older tariff distortions.
Separately, 18Horas reported, citing Folha and Agência iNFRA, that J&F’s energy arm Âmbar approved a R$9.85 billion capital injection to take over Amazonas Energia, a deeply indebted distributor. That case is not part of the R$985 billion estimate, but it shows how regulatory settlements and sector charges can also affect consumers nationwide through Brazil’s electricity-bill funds.
The central dispute is now less about whether Brazil needs backup power than how it should pay for it. Industry groups, prosecutors and consumer advocates say the bill is becoming too large and opaque. The government says the costs must be weighed against reliability, investment and the risk of more expensive emergency measures later.
