House Committee Demands Explanations and Summons Sandoval to Clarify GD Cuts

The Economic Development Committee of the Chamber of Deputies approved, this Tuesday (22), a request to summon the general director of ANEEL (National Electric Energy Agency), Sandoval Feitosa, to provide clarifications on the content of Official Letter No. 553/2025 – GDG/ANEEL, forwarded to the ONS (National Electric System Operator) on October 14th.

The document, signed by Feitosa, instructs distributors to cut not only load, but also generation in DG (distributed generation) systems — which has generated concern among parliamentarians and industry agents because it directly affects the operation of grid-connected solar systems.

The request was presented by the Committee's chairman, Congressman Lafayette de Andrada (Republicanos-MG), who highlighted the need to investigate the technical and legal grounds for the decision and assess whether the Agency's powers were exceeded when interpreting ONS commands.

“It does not seem to be the responsibility of the ANEEL express an opinion or ratify an understanding of the legality of ONS operational commands,” said the deputy.

With the approval, the general director of ANEEL must appear before the Economic Development Commission, on a date to be defined, to explain the agency's motivations and the possible impacts of the measure on the electricity sector and distributed generators.

Understand the controversy

Official Letter No. 553/2025-GDG/ANEEL, published on October 14, validated the ONS's understanding that distributors have “not only the power, but the duty to carry out generation cuts when necessary” in their concession areas, with the argument of guaranteeing the operational security of the national electrical system.

The document also states that consumers with DG would also be subject to these cuts, and cites item 48 of module 4 of PRODIST (Procedures for the Distribution of Electric Energy in the National Electric System) as support.

However, in the aforementioned excerpt, it is noted that item 48 deals with load control, with no explicit mention of the possibility of generation cuts. This position was also questioned by other directors of the company itself. ANEEL, like Agnes Costa, who advocated a more cautious and in-depth analysis of the legal aspects before any final decision on the matter.

Legal uncertainty and risk of judicialization

For lawyers specializing in the sector, the office of ANEEL It is not normative in nature, but signals a possible future regulatory understanding — which already causes legal uncertainty among market agents.

Ao Canal Solar, lawyer Matheus Soares, specialist in energy sector law and member of Martorelli Advogados, stated that the document may be challenged in court. “Arguing that DG could be the target of systemic cuts violates the essence of Law No. 14.300/2022, which established the legal framework for DG and the energy compensation system,” he highlighted.
