Enel Asks Aneel to Close Case That Could Cost It São Paulo Concession

Enel filed a 25-page final submission challenging Aneel’s restoration metrics and inspector findings and sent the dossier to director-relator Fernando Mosna before a board vote that could lead to a federal decision on the concession.

Overview

  • Enel submitted its final arguments on Thursday, July 23, asking Aneel to annul or archive the caducidade process and to resume analysis of its concession renewal request.
  • Aneel opened the caducidade procedure in April after inspectors flagged operational failings during severe storms, including low crew productivity, a sharp drop in night crews and too few large repair vehicles.
  • The companies dispute how restoration was measured for the December 10, 2025 outage: Aneel’s technical team used a 'pico simultâneo' snapshot to calculate 67% restored in 24 hours while Enel says a duration-based method would show 80.2%.
  • The agency’s technical area and the Procuradoria concluded that the documented mix of structural and operational problems justifies keeping the process open, saying the case does not rest on a single metric or event.
  • Next steps: director-relator Fernando Mosna will prepare a vote, the Aneel board is expected to deliberate around August 11, and the agency could then recommend caducidade to the Ministry of Mines and Energy for a final government decision.
