Data Centres: Boom and Backlash: Brazil judge freezes Replan grid awardsBackground
Brazil's first grid-access contest for data centres reached the Tribunal Regional Federal da 1ª Região (TRF-1) on its opening day. On 6 October 2026 one of its judges ordered ANEEL, the power regulator, to rule inside 48 hours on developer Pahlavan's injunction requests. In the meantime no winner of the year's first access season could receive a connection at the Replan substation. the Court's order, the judge said, gives no priority, holds back no capacity and approves no contract. By 17 October ANEEL had published no decision.
Pahlavan's case rests on three Paulínia projects contracted under the old access rules to rise from 71 MW to 157 MW apiece in 2029. Under the new policy the grid operator found that increase unviable.
Based in Brasília, the TRF-1 is a second-instance court of Brazil's federal justice system. It covers the Federal District and twelve states: Acre, Amapá, Amazonas, Bahia, Goiás, Maranhão, Mato Grosso, Pará, Piauí, Rondônia, Roraima and Tocantins. Minas Gerais left its jurisdiction when the TRF-6 was created in 2021.
