São Paulo, Brazil - January 13, 2026 - Brazilian renewable energy developer Casa dos Ventos has signed a long-term power supply agreement valued at more than USD 500 million to provide renewable electricity to Ascenty, one of Latin America’s largest data center operators, as demand for power-intensive digital infrastructure continues to surge across the region.
Under the agreement, Casa dos Ventos will supply clean energy generated from two new projects, a large wind complex and a solar facility, that together are expected to exceed 1.5 gigawatts of installed capacity once fully developed. The projects are scheduled to begin delivering electricity to Ascenty’s data center portfolio starting in 2027, supplying an estimated 110 average megawatts of power annually.
The wind project, known as the Dom Inocêncio complex, is located in the northeastern state of Piauí and is planned to deliver approximately 828 megawatts of capacity. The solar project, called Paraíso, will be developed in Mato Grosso do Sul and is expected to add around 640 megawatts. Combined investment across both projects is estimated at roughly USD 7.5 billion, underscoring the scale of infrastructure required to support Brazil’s fast-growing data center market.
As part of the agreement, Ascenty will take an ownership stake in the renewable projects, aligning its long-term energy needs with generation assets and reducing exposure to future power price volatility. Ascenty is jointly controlled by Digital Realty and Brookfield Infrastructure and currently operates 20 data centers across Brazil, with eight additional facilities under construction.
Casa dos Ventos CEO Lucas Araripe said the partnership reflects growing collaboration between renewable energy producers and large electricity consumers. “Data centers require reliable, long-term energy solutions, and renewables are increasingly central to meeting that demand,” he said in a statement.
Ascenty CEO Christopher Torto noted that securing a dedicated renewable supply is critical as the company scales. “This agreement supports our expansion plans while reinforcing our commitment to sustainability and grid efficiency,” he said.
The deal comes as Brazil emerges as a key data center hub in Latin America, driven by cloud adoption, AI workloads, and enterprise digitalization. Power availability has become a central constraint for new developments, pushing operators to pursue direct partnerships with energy developers rather than relying solely on traditional utility contracts.
Industry analysts view the Casa dos Ventos–Ascenty agreement as a model for future data center power procurement in emerging markets, where demand growth, sustainability targets, and grid limitations are converging rapidly.
