Brazil’s unique data center boom rides on clean power despite social burden

An analysis by The Intercept Brasil and Mongabay found that 65% of requests to connect data centers to Brazil's power grid came from renewable energy companies, with 68 requests filed across 37 municipalities by December 2025. The surge is driven by curtailment — Brazil produces more renewable power than its grid can distribute, forcing plants to halt generation and lose money, 3.2 billion reais in the first half of 2025 alone.

Companies like Atlas and Serena Energia are pitching data centers as a fix, allowing them to sign long-term power purchase deals with tech firms rather than feed surplus into the public grid. Brazil's Ministry of Mines and Energy says it wants to make the country a 'major global hub' for data center investment and frames the arrangement as mitigating oversupply.

Experts interviewed note the strategy discourages investment in transmission infrastructure that could otherwise serve ordinary consumers, electric vehicles, or coal replacement. Locals, meanwhile, pay for grid upgrades and live with the noise and water demands of the buildout.
