Casa dos Ventos and Mosaic expanded their partnership for renewable energy self-production with the commercial operation of another park, part of the Serra do Tigre Wind Complex, which began in April. Located between Rio Grande do Norte and Paraíba, the venture now includes the fertilizer manufacturer as a shareholder. The long-term contract, signed in 2025, establishes the supply of 25 average MW from the wind farm.
Evolution of the self-production model and financial impacts
The new operation follows the first agreement signed between the companies in 2022, in which Mosaic acquired a stake in the Umari Wind Complex for the supply of 30 average MW under a self-production model. Mosaic estimates savings of approximately R$ 330 million over the term of the contracts at its phosphate production units. This initiative consolidates the advancement of self-production in the Brazilian market as a strategic alternative for electro-intensive industries, ensuring cost predictability, energy security, and competitiveness.
The relationship with Mosaic reinforces our ability to develop structured and competitive solutions for large energy consumers in various sectors of the economy, including agribusiness. The fact that the client is moving forward with a second agreement with us, while the first is still in execution, demonstrates the trust built throughout the relationship, as well as the consistency and quality of our delivery and partnership.
Says Rene Abrantes, Commercial Director at Casa dos Ventos.
Strengthening the partnership with Casa dos Ventos aligns with Mosaic's sustainability pillars for 2030: People, Land, and Innovation. Thus, we reaffirm our commitment to phosphate production in Brazil while moving towards a regenerative future.
States Letícia Salles, Energy Transition Manager at Mosaic.
