Brazilian consumers are expected to face an average increase of 8,6% in their electricity bills in 2026, according to the second edition of the InfoTarifas bulletin released by [organization name]. ANEEL (National Electric Energy Agency).
The projection significantly exceeds inflation estimates for the period, calculated at 5,8% by the IGP-M and 4,9% by the IPCA, and reflects the combination of structural pressures on the sector with specific adjustments observed over the past few months.
Although the percentage represents a slowdown compared to more pessimistic scenarios discussed previously, the result reinforces the trend of maintaining the upward trajectory of electricity bills. At the same time, the report shows that extraordinary tariff moderation mechanisms have been preventing even larger adjustments.
Among these measures is the use of resources from the renegotiation of payment obligations for UBP (Use of Public Assets), intended to reduce tariffs in areas covered by the development superintendencies of Sudam and Sudene. According to the Agency, captive consumers served by 22 distributors will benefit from these discounts.
The bulletin of ANEEL This shows that the composition of the price adjustments continues to be heavily influenced by components over which distributors have little or no direct control, such as sector charges, energy purchase costs, transmission, and financial adjustments accumulated in previous cycles.
CCEARs weigh heavily in the calculations.
A detailed analysis of the report indicates that financial components remain the main driver of growth for 2026. According to... ANEELThese items account for an average impact of 4,3 percentage points on tariffs, up from 1,9 percentage points previously recorded. This represents the largest individual weight among all the components analyzed.
Among the factors that explain this increase are the rise in costs related to CCEARs contracts for availability, due to a less favorable hydrological regime; adjustments to the CVA Energia (Account for Variation of Values of Items in Parcel A); revision of components associated with neutrality and hydrological risk, in addition to changes involving tax refunds and tariff deferrals.
On the other hand, resources originating from UBP contribute to mitigating this movement, producing a reduction effect estimated at 1,6 percentage points on the final result. The return of amounts related to PIS/Cofins also helps to contain the adjustments, although to a lesser extent than previously anticipated.
Energy and transmission
Costs related to energy purchases appear as the second main source of tariff pressure. ANEEL It estimates an average impact of 1,1 percentage points resulting from this component.
Among the justifications are the expected increase in average prices of regulated energy contracts, influenced by less favorable hydrological conditions, and the reduction in quotas of Physical Guarantee Contracts associated with the privatization of Eletrobras, currently AXIA.
The report also highlights factors working in the opposite direction, such as the reduction in costs associated with Itaipu energy, benefiting from the maintenance of the transfer tariff and the expectation of a more favorable exchange rate, in addition to the decrease in quotas linked to the Angra nuclear power plant.
Transmission costs are expected to add 0,8 percentage points to the average adjustment. The main explanation is the growth in the Annual Permitted Revenues (RAPs) of transmission companies in 2025, a trend that should persist in the next tariff cycle.
Charges and distribution
Sectoral charges are expected to account for an average impact of 1,4 percentage points. The agency attributes this behavior mainly to the increase in subsidies financed by the CDE (Energy Development Account), including universalization and distributed generation programs. Conversely, the expected reduction in Proinfa costs helps to partially offset this pressure.
In the case of distribution, the projected effect is more limited, at 0,9 percentage points. Even so, the report draws attention to specific factors, such as tariff revisions with remuneration bases higher than those observed in previous cycles and updates related to the inflationary behavior used in Component B of the concessions.
More complex system
More than just anticipating the average percentage of electricity bills, InfoTarifas points to an important shift in the Brazilian tariff debate itself; that is, the final adjustment is increasingly less the result of a single factor and more of the interaction between regulatory, hydrological, financial, and sectoral variables.
The 8,6% projection for 2026 summarizes this scenario. Extraordinary resources and cost-cutting mechanisms can alleviate some of the pressure, but they do not eliminate the effects of accumulated costs over time.
The result is an electricity bill that continues to be subject to increasingly sophisticated factors, and understanding it requires looking not only at the final figures, but at the multiple components that make them up.
InfoTarifas expands on the scope of information regarding fare adjustments.
Created by ANEEL on 2025, the InfoTarifas newsletter It began to function as a kind of periodic thermometer for the electricity bills of Brazilian consumers.
Published quarterly, the publication compiles projections for tariff adjustments, details the historical evolution of residential tariffs, monitors the behavior of sectoral subsidies, presents the recent history of tariff flags, and seeks to translate, in more accessible language, the factors that influence the calculations performed by the Agency.
