Stalled $4.8 billion nuclear plant gets strict court deadline
Brazil's Federal Court of Accounts (TCU) has ordered a 240-day deadline to decide whether to complete or abandon the long-paused Angra 3 nuclear project.
Global investors holding shares of major utilities are accustomed to regulatory delays, but few power projects in the world have drained capital as quietly and persistently as Brazil’s unfinished Angra 3 nuclear plant. On October 21, 2026, the Brazilian Federal Court of Accounts (TCU) stepped in to halt the bleeding, issuing a strict 240-day deadline for the government to either finally complete or permanently abandon the $4.8 billion facility.
The unanimous ruling by the TCU, Brazil's federal audit court, targets the National Energy Policy Council (CNPE), a cabinet-level advisory body that oversees the country's energy strategy. Under the court's order, the Ministry of Mines and Energy has 120 days to deliver updated technical and financial studies, after which the CNPE has another 120 days to make a final, binding decision on the plant's fate.
Angra 3, located on the coast of Rio de Janeiro state, has been a financial black hole for decades. Construction began in the 1980s and was halted in 2015 with 66% of the work completed. While R$ 12 billion (approximately $2.4 billion USD) has already been spent, the state-backed operator, Eletronuclear, must pay roughly R$ 1 billion ($200 million USD) every single year just to maintain the stalled site and service its existing debt. Finishing the project will require an estimated R$ 23.9 billion ($4.8 billion USD) in additional funding.
The court's decision introduces a hard timeline to resolve a major source of political and fiscal risk in Brazil's energy sector. For years, the government’s indecision has weighed heavily on state planning and consumer electricity tariffs. While the federal government maintains majority control of Eletronuclear through the state-run holding company ENBPar, private capital is deeply entangled in the fallout.

The resolution of Angra 3 directly affects Eletrobras, the massive Brazilian power utility listed in New York. Eletrobras, which was privatized in 2022, sold its remaining minority stake in Eletronuclear to Âmbar Energia in October 2025 for R$ 535 million. However, the transaction required Âmbar to assume billions in debt guarantees previously backed by Eletrobras. A clear, court-mandated resolution to either scrap the project or finish it will finally remove a multi-billion-dollar cloud of contingent liability from the broader Brazilian utility sector.
