Divergent Statements Among ANEEL Directors Regarding Possible Cuts in Distributed Solar Energy Generation Create Uncertainty in the Electric Sector and Mobilize Congress, Which Demands Clarifications from the Agency on the Impact of the Measure.
The recent divergence among directors of the National Electric Energy Agency (ANEEL) has raised a warning signal among investors, consumers, and companies in the solar energy sector in Brazil. The opposing statements regarding the possibility of cuts in distributed generation (GD) have raised doubts about regulatory security and the future of the segment, which is one of the main pillars of renewable energy in the country.
The impasse began after the Director-General of ANEEL, Sandoval Feitosa, sent to the National System Operator (ONS) the Letter No. 553/2025 – GDG/ANEEL, recommending that the agency “carry out cuts not only in load but also in generation that accesses the distribution system.”
However, Director Agnes Costa publicly defended a more cautious stance, stating that the issue still needs to be analyzed from technical and legal perspectives before any definitive decision.

Lack of Consensus at ANEEL Exposes Concerns About Cuts in Distributed Generation
The internal divergence highlights a lack of alignment within ANEEL on a highly sensitive topic: the possibility of including small photovoltaic solar energy generators among the measures of curtailment, a term used to describe generation cuts in moments when balance in the electric system is needed.
The letter sent by Feitosa states that “the prerogative is supported by regulations and Network Procedures“, which, in practice, would open the door for distributors to interrupt the generation of consumers and producers connected to the grid, including micro and mini-generators.
This interpretation, however, is viewed with concern by specialists and sector representatives, who warn about the possible economic and legal impacts. The uncertainty regarding the legality and implementation of the measure could affect thousands of investors and Brazilian families who have bet on solar energy as a sustainable and financially advantageous alternative.
Deputy Lafayette de Andrada Demands Explanations from ANEEL Regarding Controversial Measure
The impasse has reached the National Congress. Deputy Lafayette de Andrada (Republicanos-MG), chairman of the Economic Development Committee of the Chamber of Deputies, filed Request No. CD256956930300, inviting the director-general of ANEEL to provide official clarifications regarding the content and foundations of Letter No. 553/2025.
In the document, the lawmaker highlights that “it does not seem to us that ANEEL is the agency that should opine, ratify understanding, or resolve doubts concerning the legality of orders from ONS“. The statement reinforces the need for transparency and institutional alignment among the agencies in the electric sector, especially on issues involving solar energy generation and access for small producers to the grid.
Solar Energy Market Calls for Legal Security and Regulatory Stability
The solar energy sector, responsible for generating billions of reais and creating thousands of jobs in Brazil, heavily relies on regulatory predictability to continue growing. The lack of consensus within ANEEL regarding cuts in distributed generation concerns companies and consumers, who fear a setback in the incentive policies for clean sources.
Furthermore, the conflicting information generates insecurity for new investments, at a time when the country seeks to increase the participation of renewable energy in its matrix. Analysts assess that the episode highlights the need for harmonization between ANEEL and ONS, ensuring clarity in decisions affecting distributed generation and the advancement of solar energy in Brazil.
Diretores da ANEEL, precisam entender que investidores,empresas e consumidores investiram muito dinheiro em energias renováveis acreditando nesse mercado que gera muitas oportunidades e contribui para o desenvolvimento sustentável. Vivemos uma transição energética e precisamos de investimento em infraestrutura e novas tecnologias para transmissão e distribuição dessa energia produzida no Brasil. O simples corte de energia não é a solução do problema! Estão querendo impedir o país de aproveitar seu potencial energético e desperdiçar a energia que é produzida.
Precisamos de pessoas na ANEEL,que tenham conhecimentos técnicos e conheçam de verdade o sistema elétrico brasileiro.
O problema que colocam políticos sem serem técnicos, apenas para terem apoio político. Esse é o motivo do público muitas vezes não funcionar.
