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.
