In recent weeks, conflicting statements from directors of ANEEL (National Electric Energy Agency) have been generating confusion and concern among agents in the electricity sector.
While Director General Sandoval Feitosa forwarded Official Letter No. 553/2025 – GDG/ANEEL to the ONS (National System Operator), recommending that the agency “carry out the cut not only of load, but also of generation that accesses the distribution system”, another director of the Agency, Agnes Costa, publicly stated that the issue still needs to be analyzed carefully, especially in legal aspects, before any definitive decision.
The internal contradiction exposes a lack of alignment on an extremely sensitive issue: the possibility of including DG (distributed generation) composed of small generators, with small photovoltaic solar systems in the curtailment measures.
Sandoval's letter reinforces that "the prerogative is supported by regulations and Network Procedures," which, in practice, would open the way for distributors to interrupt generation for consumers and producers connected to their networks, including micro and mini-generators.
Agnes requests legal analysis on the inclusion of MMGD in the curtailment mechanism
The more cautious position of other members of the board of directors ANEEL on the legality of such a measure shows that there is no technical or legal consensus on the application of this measure to GD, especially given the economic and regulatory impacts this could have on millions of Brazilians.
The disagreement in demonstrations within the Agency has already provoked a reaction in Parliament. Representative Lafayette de Andrada (Republicans-MG), president of the Economic Development Committee of the Chamber of Deputies, filed Request No. CD256956930300, inviting the Director General of the ANEEL to provide clarification on the content and basis of the Official Letter No. 553/2025 before the committee.
The request highlights that “it does not seem to us that it is the ANEEL the body that must provide an opinion, ratify understanding or resolve doubts about the legality of ONS commands”, reinforcing the need for transparency and institutional alignment regarding the Agency’s actions.
