The General Comptroller’s Office (CGU) identified serious transparency failures in Enel SP’s operational data, calling into question the credibility of the information sent about the 2025 blackout.
The credibility crisis of Enel Distribuição São Paulo has reached a new level of complexity. An audit conducted by the General Comptroller’s Office (CGU) revealed a series of discrepancies in the human and material resource records that the concessionaire claimed to have mobilized during the severe weather event in December 2025.
The investigation, which now forms part of the evidentiary framework for the revocation process, questions the integrity of the information submitted to the National Electricity Agency (ANEEL). The document points out that the company’s fragile data collection and traceability systems prevent an independent audit, creating uncertainty about the distributor’s actual response capacity during severe crises.
Operational discrepancies under scrutiny
CGU auditors cross‑checked several databases provided by the concessionaire and found alarming inconsistencies. The mismatches appear both in the count of allocated vehicles and in the geographic and quantitative distribution of field teams, making it practically impossible to verify whether the company met the support promised to São Paulo residents.
For experts, this is not just a data entry error but a structural barrier to regulatory control. Without precise, auditable data, ANEEL’s ability to monitor Enel SP’s operational performance during extreme weather events is severely compromised.
Transparency failures undermine independent verification of the resources used in the emergency response, weakening regulatory analysis of the concessionaire’s performance.
The Impact on the Termination Process
This new report arrives at a pivotal moment for the future of the concession contract. The administrative process, initiated by ANEEL in April 2026, examines the recurring history of failures to restore power, covering the company’s performance from 2023 to 2025. With the instruction phase already concluded, the findings of the CGU add a layer of technical mistrust to the process.
While Enel SP disputes the grounds leading to the recommendation to terminate the contract, the board of ANEEL maintains a firm stance, having recently denied requests for suspension and additional inspections requested by the distributor. The final word on the potential termination remains in the hands of the Ministry of Mines and Energy (MME).
The outcome of this clash will not only decide the continuation of Enel‘s operations in São Paulo, but will also serve as a watershed moment in how the Brazilian electric sector monitors the conduct of concessionaires during climate crises, demanding, from now on, much stricter standards of transparency and data traceability.
