Enel Faces São Paulo Concession Loss After Brazil Rejects Appeal
Brazil's government lawyers have rejected Enel's appeal against a cancellation process targeting its largest Latin American asset, raising the prospect of a forced exit that would reshape the Italian utility's regional strategy.
Government lawyers filed an opinion on July 10 rejecting Enel's appeal, keeping alive a process that could cancel the company's São Paulo electricity distribution concession. The filing went to the case officer at Brazil's energy regulator, Aneel, who is weighing the Italian company's defence. Lawyers concluded that Enel failed to demonstrate any illegality in the regulator's decision to open the case.
The São Paulo operation represents Enel's largest foothold in Latin America and accounts for a substantial portion of the company's global revenue. Losing the concession would force a major recalibration of Enel's regional strategy. It serves one of the wealthiest and most densely populated urban markets on the continent, making it a cornerstone asset for the group.
Aneel opened the cancellation process, known locally as caducidade, on April 7. The immediate trigger was a December 2025 extratropical cyclone that cut power to well over two million customers, some for extended periods. Business groups blamed the prolonged outages for heavy losses across São Paulo's retail and service sectors, which intensified political pressure on both the utility and the regulator.
Enel has argued that just over 80 percent of affected units had power restored within 24 hours, disputing Aneel's figure of 67 percent. Government lawyers dismissed this defence, noting that even if Enel's calculation were fully accepted, the cancellation case would still stand. Inspectors documented a long list of operational shortcomings, including high average emergency response times, frequent day-long outages, and problems mobilising field crews during extreme weather.
Enel has called the regulatory process procedurally flawed, pointing to improved performance indicators following recent major blackouts. The concession contract otherwise runs until 2028, but Aneel suspended any early renewal when it opened the case. Cancellation remains the most extreme penalty available to the regulator, applied only when a concessionaire is deemed to have broken its contract and cannot serve the public properly.
While the defence phase continues and a final decision is not imminent, the rejection of the appeal signals institutional resolve to enforce service standards on privatised utilities. Aneel's director general has indicated that the most likely negotiated solution would be a transfer of control to another operator. This mirrors the outcome in Goiás state, where Enel handed its concession to the Equatorial group.
