Brazil’s National Electric Energy Agency (ANEEL) has approved two public consultations addressing the effects of the Tax Reform on the regulated electricity sector.
The consultations, open for contributions from October 21 to October 30, 2026, seek to adapt tariff mechanisms, regulated contracts and sector charges to the transition from PIS/Pasep and Cofins toward the new CBS and IBS framework.
The first consultation addresses the treatment of remaining PIS/Cofins tax credits associated with electricity distribution and transmission assets.
ANEEL proposes preserving existing Regulatory Remuneration Bases while introducing transitional financial adjustments to prevent inappropriate recognition of legacy tax credits.
The second consultation concerns regulated electricity generation and commercialization contracts, as well as sector charges.
The proposed methodology includes adjustments to remove PIS/Cofins components from certain contract prices established before January 16, 2025, using rates corresponding to the applicable tax regimes.
Market Impact
The proposed adjustments may affect:
- electricity generators and distributors
- transmission concessionaires
- regulated electricity commercialization contracts
- concession revenues and tariff calculations
- investment remuneration
- contractual pricing and financial projections
The consultations are particularly relevant to companies with long-term regulated contracts extending into the tax transition period.
Legal & Regulatory Implications
Companies should review:
- tax allocation and price-adjustment clauses
- economic-financial equilibrium provisions
- treatment of legacy PIS/Cofins credits
- regulated tariff calculation mechanisms
- contractual assumptions concerning CBS and IBS
- potential impacts on concession revenues and financial models
The proposals remain subject to public consultation and should not yet be treated as final regulatory requirements.
With the consultation period ending on October 30, affected companies have a limited opportunity to submit technical and legal contributions before the agency determines the final adjustments.
