Data Centres: Boom and BacklashBackground
Replan, the Refinaria de Paulínia, is Petrobras's largest refinery, in the interior of São Paulo state. It began operating in February 1972 and processes about 434,000 barrels a day, roughly 20% of Brazil's oil refining, according to Petrobras. Its output covers diesel, petrol, jet fuel, liquefied petroleum gas, asphalt and petrochemical feedstocks.
Its substation is now the most fought-over data-centre grid connection in Brazil. Pahlavan holds contracts for three Paulínia projects that were each to grow from 71 MW to 157 MW of grid use in 2029, an increase The National grid operator rejected as unviable under the new transmission-access policy. A federal appeals judge stepped in on 6 October 2026, giving ANEEL 48 hours to decide and barring any new connection award at Replan for this year's first access-season winners in the meantime. The order, the judge said, granted no one priority, held back no capacity and approved no contract.
Across São Paulo, demand for grid access runs at about twice what is on offer. In the first competitive round, on 6 and 7 October 2026, seven qualified projects asked for 451 MW at four connection points; three data centres shared the 228 MW available, and Pahlavan won two of those slots.
