Brazil’s Federal Audit Court (TCU) has ordered the country’s top energy regulator to complete a full verification of service quality data for the Enel Rio power distribution concession within 120 days, signaling a significant tightening of regulatory scrutiny on a major foreign-owned utility. The decision by the TCU—Brazil’s federal spending and contract oversight body, similar to a supreme audit institution—directly addresses an "omission" by the National Electric Energy Agency (ANEEL) in fully validating the operational performance of Enel Rio, whose contract is set to expire in December. The court determined that while the company met formal and economic-financial criteria for a potential renewal, ANEEL had failed to adequately verify crucial data on power continuity, forcing the process to halt until the metrics are confirmed.
