Omnia, a Brazilian data center platform, has signed a 20-year energy supply deal with renewable energy firm Casa dos Ventos to power its data center, which set to host TikTok owner ByteDance.

According to reporting from Reuters, the companies signed a $2 billion deal to power the data center, located at the Pecem port complex ​in the northeastern state of Ceara.

The data center is currently under development and, when completed, is expected to be the largest in Brazil, representing a total investment of more than $39bn. Construction at the data center commenced in January, with initial operations slated for Q3 in 2027, and expansion occurring gradually in phases until 2029.

The power will be supplied from the 630MW Ibiapaba wind complex and the Dom Inocencio wind farm in Piauí state, both of which are owned and operated by Casa.

According to the reports, the deal is structured as a self-production model, providing Omnia a stake in Casa’s assets. The stake was not disclosed. The deal marks Casa’s largest with a single offtaker. The company has previously signed power supply agreements with Odata and Ascenty in recent years.

News of the data center first surfaced last year, with a Reuters report revealing that it would have an initial capacity of 300MW with the potential to scale to 900MW. Casa subsequently received regulatory approval for the project in June 2025. Patria joined the scheme the following month, with the firm expected to act as the main developer on the project, on behalf of Casa.

Casa dos Ventos is one of Brazil's largest renewable energy developers. It has an operating and under-development portfolio of approximately 33.4GW of wind and solar projects, including 12GW in a joint venture with French energy giant TotalEnergies.

Omina is a subsidiary of Patria Investimentos, which launched the firm in May of last year. The firm is positioned as a hyperscale data center platform aimed at meeting the growing demand for artificial intelligence infrastructure.
