Aneel unanimously approves R$64.5bn energy auction with deliveries through 2031

Disagreements over policy merit do not justify stopping a properly conducted auction
Aneel's chief counsel explained why the agency moved forward despite institutional opposition to the energy auction.

Em um momento em que o Brasil busca equilibrar crescimento econômico e segurança energética, a Aneel aprovou por unanimidade dois leilões de reserva de capacidade avaliados em R$64,5 bilhões, contratando quase 19 gigawatts de geração hídrica e termelétrica com entregas previstas até 2031. A decisão, tomada após semanas de tensão institucional envolvendo o Ministério Público Federal, o Tribunal de Contas e o Judiciário, reafirma o entendimento de que um processo licitatório conduzido dentro das regras não pode ser paralisado por divergências sobre mérito de política pública. No horizonte, o país sinaliza que a convivência entre fontes renováveis e geração térmica não é contradição, mas condição para a estabilidade de uma economia em expansão.

  • Semanas de disputas jurídicas, questionamentos do TCU e intervenção do Ministério Público criaram uma nuvem de incerteza sobre leilões que movimentam R$64,5 bilhões e definem o futuro elétrico do país.
  • A Aneel reuniu seu conselho em sessão pública extraordinária para dissipar as dúvidas: nenhuma liminar, nenhuma cautelar e nenhum impedimento administrativo justificavam bloquear os resultados.
  • A licitação competitiva gerou R$33,64 bilhões em economia no primeiro leilão e outros R$1,83 bilhão no segundo, com lances chegando 50% abaixo do preço de reserva para usinas a óleo e biodiesel.
  • Com 18,97 GW contratados de fontes hídricas, gás, carvão e biocombustíveis, o sistema elétrico brasileiro ganha uma âncora de confiabilidade para sustentar a demanda até 2031.
  • O setor termelétrico celebra a homologação como a conclusão de um debate que durou cinco anos, argumentando que sem essa base firme o crescimento econômico do país caminharia sobre terreno instável.

A Aneel deu seu aval unânime na quinta-feira a dois grandes leilões de reserva de capacidade realizados em março, encerrando semanas de tensão institucional que envolveram o Ministério Público Federal, o Tribunal de Contas da União e o Judiciário. Após reunião pública extraordinária do conselho, a agência concluiu que não havia qualquer obstáculo legal, judicial ou administrativo que impedisse a homologação dos resultados.

O diretor Fernando Mosna liderou a argumentação: a Aneel cumpriu rigorosamente as regras do edital, e a responsabilidade pelo desenho e modelagem dos leilões cabia ao Ministério de Minas e Energia e à empresa de pesquisa estatal. O diretor-geral Sandoval Feitosa reconheceu o acalorado debate público, mas defendeu o trabalho técnico da equipe. O conselheiro jurídico Eduardo Ramalho foi direto: divergências sobre mérito de política energética não autorizam paralisar um processo licitatório conduzido dentro da legalidade.

O primeiro leilão, em 18 de março, contratou quase 19 gigawatts de capacidade hídrica e termelétrica — gás natural e carvão — totalizando R$64,5 bilhões em investimentos com entregas entre 2026 e 2031. A disputa competitiva reduziu os preços em 5,52%, gerando R$33,64 bilhões em economia. Três dias depois, um segundo leilão acrescentou 501 megawatts de usinas a óleo combustível, diesel e biodiesel, com lances 50% abaixo do preço de reserva e mais R$1,83 bilhão em economia.

A Associação Brasileira dos Produtores Independentes de Energia Elétrica saudou a decisão como correta e necessária, lembrando que o debate sobre esses leilões se arrastava há cinco anos. Para o setor, a mensagem é clara: renováveis e geração a gás precisam coexistir para que o Brasil mantenha a confiabilidade do sistema e não coloque em risco sua trajetória de crescimento econômico.

Brazil's energy regulator gave its unanimous blessing on Thursday to two major capacity auctions that will pump billions into the country's power grid over the next five years. The National Electric Energy Agency, known as Aneel, formally approved the results of the March auctions after an extraordinary public board meeting in which directors concluded there were no legal, judicial, administrative, or oversight barriers standing in the way.

The decision came after weeks of institutional tension. The Federal Public Ministry had weighed in, as had Brazil's audit court. A judge had issued a ruling. But Aneel's leadership, led by director Fernando Mosna, determined that the agency had followed every procedural requirement in the auction rules and that no court orders or precautionary measures from the audit court existed to block the results. Mosna emphasized that Aneel's job was simply to run the auction itself—the design and modeling had been the responsibility of the Energy Ministry and the state research company. The agency's general director, Sandoval Feitosa, acknowledged the intense debate surrounding the matter but praised the technical work his team had done. The agency's chief counsel, Eduardo Ramalho, made the institutional stakes clear: Aneel must operate according to the directives it receives from the government, and disagreements over policy merit do not justify stopping a properly conducted bidding process.

The first auction, held on March 18, locked in contracts for nearly 19 gigawatts of capacity from hydroelectric plants and thermal generators burning natural gas and coal. The total investment commitment came to R$64.5 billion, with power deliveries scheduled between 2026 and 2031. Competitive bidding drove prices down by 5.52 percent, creating an estimated R$33.64 billion in savings for the system. A second auction three days later added another 501 megawatts from plants running on fuel oil, diesel, and biodiesel. Those contracts, which will last three years, saw bids come in 50.14 percent below the reserve price, saving another R$1.83 billion.

The Brazilian Association of Thermal Generators, which represents many of the companies that won contracts, called the approval both correct and necessary. In a statement, the group noted that the auction had been debated across the power sector for five years and was essential to keep the national grid stable and secure. The association underscored a central argument in the debate: renewable energy sources need to coexist with natural gas generation to ensure the system can handle growth and maintain reliability. Without that balance, the group warned, Brazil risked putting its economic future on an uncertain and dangerous path.

Why did this auction take so long to approve? It seems like a straightforward business decision.

Model

It wasn't straightforward at all. This touches something deeper—the question of how much thermal generation Brazil needs as it shifts toward renewables. Some people argued the auction was unnecessary or poorly designed, and they took that argument to court.

Inventor

And Aneel just decided to ignore those objections?

Model

Not ignore them. The agency reviewed every legal challenge, every government office that weighed in. But ultimately, Aneel concluded that it had followed the rules correctly and that disagreements about policy don't stop a properly run auction.

Inventor

So who wins here?

Model

The thermal generators win contracts. The grid gets more capacity to draw on when the sun isn't shining and the wind isn't blowing. And consumers win through the bidding discounts—R$33 billion in savings.

Inventor

But there's still tension, isn't there?

Model

Yes. The renewable energy advocates worry this locks in fossil fuel generation for years. The thermal side argues you can't run a modern grid on renewables alone. Both sides are right about something.

Inventor

What happens next?

Model

The contracts start delivering power in 2026. The real test is whether the grid actually needs this capacity or whether it becomes expensive insurance nobody wanted.
