Enel filed a request with the Agência Nacional de Energia Elétrica (Aneel) on July 23 to annul the process that could end its concession [3].
The outcome of this administrative caducity process determines whether Enel will continue to distribute electricity in the state of Sao Paulo. A loss of the concession would represent a significant operational and financial blow to the company in one of Brazil's most populous regions.
In its latest filing, Enel asked for a technical expertise, or perícia, to be conducted as part of the proceedings [2]. The company said the current process is procedurally invalid and that Aneel has ignored recent improvements in service indicators following previous power outages [1, 5].
This legal battle has seen several escalations over the last few months. Enel first submitted a defense claiming the process was invalid on May 13 [2]. However, the Attorney General's Office (AGU) rejected those arguments on July 11, saying that the process to revoke the concession must continue [1].
Enel said the dispute is based on technical disagreements rather than a failure to provide service [5]. The company continues to contest Aneel's calculations regarding its performance and seeks a full review of the case [3].
Despite these filings, the timeline for a final decision remains unclear. Aneel avoided providing an estimated date for the vote on the caducity process on July 14 [4]. A spokesperson for Enel said the process to end the concession in Sao Paulo is "inválido" [5].

The conflict highlights the tension between regulatory oversight and corporate operational claims in Brazil's energy sector. If Aneel proceeds with the caducity, it would signal a strict regulatory approach to service failures, potentially opening the door for a new operator in Sao Paulo. Conversely, if Enel succeeds in proving the process is invalid or that indicators have improved, it preserves the status quo of the current distribution model.
