By Brazil Stock Guide – Brazil’s federal government hardened its stance against Enel Distribuição São Paulo, controlled by Italy’s Enel Brasil Energia, four days after a blackout triggered by strong winds and heavy rain left more than 2.2 million households without power across Greater São Paulo. As of Sunday (Dec. 14), 67,000 properties were still without electricity, according to official data.
In a statement, President Luiz Inácio Lula da Silva ordered absolute rigor in oversight of power distribution, while the Ministry of Mines and Energy said it may pursue a revocation of the concession if contractual and quality targets are not fully met.
Enel São Paulo’s concession serves about 7.7 million consumer units, making it Brazil’s largest electricity distribution market and a critical hub for economic activity and public services. The sequence of outages exposed weaknesses in grid resilience, response to extreme weather events, and service restoration times, intensifying scrutiny over investment levels, network maintenance and operational management.
Federal response escalates
According to the energy ministry, authorities ordered the immediate mobilization of the power sector, coordinating public agencies and companies to restore service as quickly as possible. The ministry also created a national task force, supported by other distributors, to reinforce field teams and accelerate repairs in the areas most affected by storms and high winds.
Energy Minister Alexandre Silveira said there would be no leniency toward failures to meet service quality and continuity standards. The remarks mark a shift from the minister’s previously more cautious tone, as he had defended the extension of power distribution concessions and avoided direct confrontation with Enel.
The federal government’s tougher posture also brings it closer to criticisms voiced by São Paulo Mayor Ricardo Nunes and Governor Tarcísio de Freitas, both political opponents of Lula, who have called for the immediate termination of the contract, which is set to expire in 2028.
The shift in tone comes amid a broader tightening of Brazil’s regulatory framework for the power sector. In 2024, the government enacted Decree No. 12,068, which imposed stricter oversight rules on electricity distributors nationwide, expanding technical and contractual requirements. In practice, the decree strengthened the state’s authority to penalize underperforming concessionaires, including through the possibility of early re-tendering of concessions.
Enel response
Enel Distribuição São Paulo said late Sunday that power supply is returning to normal after outages caused by an extratropical cyclone on Dec. 10–11. The company said it deployed a record 1,800 field crews and cited wind gusts of up to 98.1 km/h (61 mph), calling the event the longest sequence of winds above 70 km/h recorded in São Paulo since 2006.
