Located in the states of Piauí and Pernambuco in northeast Brazil, the 456 MW facility reinforces Hydro Rein's long-term commitment to accelerating the energy transition both in Brazil and globally.
Developed in partnership with Macquarie Asset Management, and backed by long-term power purchase agreements (PPAs) with Hydro's alumina refinery and mining operations in Brazil, the wind complex comprises 80 turbines and is expected to generate approximately 2 TWh of renewable electricity annually.
The inauguration ceremony was attended by more than 100 guests, including Governor Rafael Fonteles of Piauí and Mayor Magno Dantas of Simões. The celebration featured cultural performances by a local dance group and traditional foods from the region, highlighting the project's deep ties to the surrounding communities.
"This is a proud day for Hydro Rein, our partners, and the communities of Araripina and Simões," said Olivier Girardot, CEO of Hydro Rein. "The inauguration of Ventos de São Zacarias is a powerful example of what long-term industrial vision and strong collaboration can achieve. By delivering clean, competitive energy to Hydro's operations, we are contributing to the decarbonization of one of the world's most energy-intensive industries and helping to secure Brazil's sustainable energy future."
The inauguration brought together project partners, government leaders, community representatives, and employees to celebrate a major milestone in Brazil's clean energy journey and to reaffirm the shared commitment to inclusive and sustainable development.
The complex is owned by Hydro Rein, Macquarie Asset Management, Mineração Paragominas, and Alunorte, and was developed and is operated by the joint venture company Ventos de São Zacarias.
