Aneel Opens Process to Revoke Enel São Paulo Concession

Overview

• Aneel, which voted unanimously Tuesday, opened an administrative caducity case against Enel São Paulo and gave the utility 30 days to submit its defense.
• Regulators cited slow emergency response, a rise in outages lasting more than 24 hours, and weak contingency plans during severe storms from 2023 to 2025, saying millions in greater São Paulo were left without power and recovery lagged peers.
• After the defense, Aneel may recommend termination to the Mines and Energy Ministry, which has the final say, and press reporting estimates an indemnity of about R$13–14 billion if caducity is declared.
• In a separate step Monday, the ministry called 14 distributors to sign 30‑year renewals within 60 days under 2024 rules that tighten quality and financial requirements, and it left Enel’s three concessions off the list.
• Aneel also launched a consultation Tuesday for an October 30, 2026 transmission auction with R$11.3 billion in planned investments, including projects to expand capacity and a Brazil–Colombia interconnection.
