Data Centers Dominate Energy Bid in São Paulo, Intensifying Debate Over Transmission Infrastructure.
The data center sector demonstrated its significant influence by securing the entirety of the energy transmission capacity made available in São Paulo during a federal auction. Three companies linked to these developments acquired 228 MW, a substantial volume, in the first competitive process under the National Policy for Access to the Transmission System (PNAST).
This move comes at a critical time for the expansion of digital infrastructure in Brazil, also driven by tax incentives such as Redata. The victory of the data centers sparks important discussions about the national transmission grid’s capacity to support the growing energy demand of these complexes.
Advancement of Digital Giants
The winning projects were Pahlavan One and Pahlavan Three, both part of the Pahlavan Complex project in Paulínia (SP), controlled by the global company CloudHQ. The third company to secure capacity was Digital DC Brasil, operating as NextStream, a consolidated player in digital infrastructure in Latin America.
These companies secured 100% of the 228 MW offered by the federal government in São Paulo. The tender saw participation from seven projects, which collectively submitted an enabled demand of 451 MW, highlighting the intense competition for access to the basic grid.
Debate Over Transmission Infrastructure
The acquisition by data centers raises a red flag for the electricity sector regarding the urgent need to accelerate the expansion of Brazil’s transmission system. Experts point out that the current pace could become a bottleneck for the development of more data centers in the country.
An industry expert, who prefers to remain anonymous, commented:
The expansion of the transmission network must keep pace with demand. We need more investment and more auctions to ensure Brazil can accommodate these developments sustainably and efficiently.
The PNAST, implemented by the Ministry of Mines and Energy (MME) and the National Electric System Operator (ONS), aims to optimize access to the transmission grid, replacing the old “open queue” system. The new model includes periodic “Access Seasons” where requests are evaluated jointly, considering available capacity and technical criteria.
Next Steps and Impact
Starting in 2027, PNAST will feature two annual access seasons, which should increase predictability and efficiency in granting grid access. The total demand registered in the first season exceeded 43 GW, with approximately 30.7 GW being made viable.
The strong presence of data centers in this first competitive process signals a clear trend. Brazil is solidifying its position as an attractive destination for digital infrastructure, but long-term success will depend on the country’s ability to expand its energy transmission network robustly and in a planned manner.
