- The Ministry of Mines and Energy (MME) demanded more rigorous action from the National Electric Energy Agency (ANEEL) in overseeing distributors after gales and storms blacked out parts of Rio de Janeiro and São Paulo.
- In a letter sent on Thursday (30) to director-general Sandoval Feitosa, Minister Alexandre Silveira asked ANEEL to evaluate power interruptions on Wednesday (29) that left nearly 2 million consumer units without power.
- In Rio de Janeiro, the storm cut power for approximately 1.9 million customers served by Light and Enel Rio; in São Paulo, winds and rain interrupted service to more than 70 customer units within Enel São Paulo's concession area.
- The Ministry requested an investigation into the distributors' actions and reinforced the need for a coordinated response; the minister determined ANEEL should verify contingency plans and concession obligations and receive reports on restoration measures.
- ANEEL said it had already notified the presidents of Light and Enel Rio, was monitoring restoration, and may adopt administrative measures if regulatory non-compliance is identified.

In a letter to ANEEL's Director-General, Sandoval Feitosa, Minister Alexandre Silveira requested an evaluation of the power supply interruptions that occurred on Wednesday (29). The storms left approximately 1.9 million customers in Rio without power, primarily affecting consumers served by Light and Enel Rio.
In São Paulo, the storms disrupted service to more than 70 customer units within Enel São Paulo's concession area. The Ministry is demanding an investigation into the actions of the distributors during the incident, focusing on whether their contingency plans were executed properly and if they met their contractual obligations.
Silveira also emphasized the need for a coordinated response and requested that all measures taken by the distributors to restore power be reported to the MME for monitoring purposes. Even prior to the official letter, ANEEL had already reached out to the presidents of Light and Enel Rio for clarifications regarding the outages.
The agency is actively monitoring the restoration efforts and may take administrative action if any regulatory non-compliance is identified during the emergency response.
“Minister Alexandre Silveira's Thursday letter to ANEEL Director-General Sandoval Feitosa asked the agency to evaluate the outages, verify contingency plans, and check whether concessionaires met their contract obligations. ANEEL had already notified the presidents of Light and Enel Rio, and may adopt administrative measures if regulatory failures are found.”
