Data Centers Emerge as Major Force in Brazil's Free Energy Market
March 25, 2026

Data centers have rapidly ascended to become one of the leading consumers in Brazil's free energy market, signaling a profound shift in the country's power demand landscape driven by digitalization and artificial intelligence. This trend underscores the growing energy intensity of the technology sector and its increasing influence on national energy planning and infrastructure development.

According to a report released Wednesday by consultancy Clean Energy Latin America (CELA), data center projects were the fourth-largest segment by volume in securing long-term power purchase agreements (PPAs) in Brazil's free market for 2025. These projects contracted 150 average megawatts (MWa), trailing only the general industrial sector (168 MWa), mining (168 MWa), and the metallurgical industry (165 MWa). The energy sourced through these agreements is predominantly from wind and solar projects.

Overall, CELA mapped 40 contracts signed in 2025 within the free market, involving 1,207 MWm of traded energy and linked to projects with a total installed capacity of 4.2 gigawatts (GW). This volume marks an 83% surge compared to 2024, which saw 659 MWm traded from 31 agreements tied to 2.3 GW of capacity. A notable feature of the 2025 contracts was that 41% were denominated in US dollars, reflecting a market evolution towards more sophisticated financial structures alongside traditional deals indexed to local inflation. “We have seen greater competitiveness in contracts in dollars, especially among consumers with foreign exchange exposure and sophisticated structures, due to more advantageous financing rates than in Brazil,” explained Camila Ramos, CEO of CELA.

While the 2025 rush was partly fueled by a push to sign self-production contracts before the expiration of certain subsidies under the new regulatory framework, Ramos remains cautiously optimistic for the coming year. “But we are involved in many processes for contracting energy, so I believe it will be an interesting year,” she told BNamericas.

The data center boom is further corroborated by national grid connection data. The National Electric System Operator (ONS) recently admitted 34 data center ventures seeking connection, with a combined load of 7,040 MW. Furthermore, the draft of Brazil's Ten-Year Energy Plan (PDE) 2035, prepared by the Energy Research Company (EPE), identifies 77 data center projects in the pipeline, totaling a staggering 26.3 GW of potential installed capacity. This is a dramatic increase from the 12 projects with 2.5 GW noted in the previous plan. EPE attributes this explosive growth to the rapid expansion of artificial intelligence and broader economic digitalization, which is sharply elevating demand for data processing infrastructure.

The rise of data centers as anchor energy consumers is set to reshape Brazil's power sector, influencing investment in renewable generation, transmission infrastructure, and market contract models. Their massive and concentrated demand presents both a challenge for grid stability and a significant opportunity for renewable energy developers seeking long-term, bankable offtake agreements.
