Brazilian renewable energy developer Casa dos Ventos and Ascenty, one of Latin America’s leading data center operators, have signed the largest renewable energy contract ever announced for data centers in the region.
Valued at more than USD 500 million, the agreement covers the supply of an average 110 MWm of renewable electricity, reinforcing the growing role of long-term clean power contracts in supporting Latin America’s digital infrastructure expansion.
Casa dos Ventos currently has more than 4.3 GW of wind, solar, and hybrid projects in operation and under construction across Brazil. Under the terms of the deal, Ascenty will acquire an equity stake in two renewable energy projects developed by Casa dos Ventos. Both projects are currently under development and are expected to begin commercial operations in 2027.
Combined, the two assets will have an installed capacity exceeding 1.5 GW, highlighting the scale at which renewable generation is being developed to meet the rapidly rising power demand from data centers.
For Casa dos Ventos—of which TotalEnergies holds a 34% stake—the partnership strengthens the company’s strategic expansion into the data center segment. This market is experiencing accelerated growth, driven by cloud computing, artificial intelligence, and digitalization, all of which require reliable, clean, and long-term energy solutions.
“Ascenty operates in a sector that is critical to digital transformation,” said Lucas Araripe, CEO of Casa dos Ventos. “Supplying renewable energy through this agreement underscores Casa dos Ventos’ role in supporting new infrastructure and innovation demands in Brazil. Our partnership is built on the complementarity of renewable sources, supply reliability, and a long-term vision.”
Long-term clean energy and decarbonization
The contract structure, which combines different renewable energy sources, enhances operational flexibility and enables more robust energy planning for Ascenty throughout the duration of the agreement.
According to the companies, the collaboration will allow Ascenty to avoid approximately 5 million tons of CO₂ emissions over the coming years, contributing significantly to its decarbonization goals.
“This initiative strengthens our decarbonization strategy,” said Christopher Torto, CEO of Ascenty. “The combination of renewable energy sources and the security of long-term supply provides greater predictability for the expansion of our operations across Latin America.”
The transaction was advised by Clean Energy Latin America (CELA), a consultancy specialized in renewable energy procurement and power purchase agreements (PPAs) in the region.
Beyond emissions reductions, the agreement positions renewable energy as a key enabler of next-generation digital infrastructure.
“For us, working with clean and renewable energy means enabling new digital capabilities,” Torto added. “By aligning energy efficiency with technological innovation, we are laying the foundations for data centers that can scale to support the full potential of artificial intelligence, delivering advanced solutions for strategic sectors across Latin America.”
