In a decisive move that signals the reactivation of Brazil’s wind energy market, Danish turbine manufacturer Vestas has secured a massive 828 MW order from renewable energy giant Casa dos Ventos. The partnership centers on the development of the Dom Inocêncio wind complex, located in the high-yield wind corridor of south-central Piauí. This agreement marks the first large-scale wind energy investment announced in Brazil since 2023, ending a period of sector stagnation and reaffirming the country’s position as a global renewable powerhouse.
The deal involves the supply and installation of 184 V150-4.5 MW turbines, a model that has become a staple for optimizing power generation in Brazilian wind conditions. Beyond the hardware, the contract includes a 25-year Active Output Management 5000 (AOM 5000) service agreement, ensuring Vestas will oversee the long-term performance and maintenance of the assets. Construction is slated to begin in 2026, with the complex expected to be fully commissioned and operational by 2028.

A Multi-Billion Real Investment
The Dom Inocêncio complex represents a total investment exceeding BRL 5 billion (approximately USD 850 million). Once operational, the facility will generate enough clean electricity to power approximately 2 million Brazilian homes, significantly bolstering the national energy grid’s security and sustainability.
“This new agreement is yet another demonstration of our commitment to supporting the expansion of Brazil’s renewable energy matrix,” said Lucas Araripe, Executive Director of Casa dos Ventos. “In addition to driving the country’s energy transition, our investment will also significantly boost the socio-economic development of the region.”
Revitalizing the Supply Chain
The project is expected to be a major economic engine for the state of Piauí and the broader Brazilian wind sector—a regional renewable momentum also underscored as Microsoft and Canadian Powertrust sign a deal for a 270 MW solar project in Mexico and Brazil. Additionally, estimates suggest the development will create over 8,500 direct and indirect jobs during the construction and operational phases. By securing such a substantial order, Casa dos Ventos is also stimulating the local supply chain, which had faced uncertainty during the recent market slowdown.
Eduardo Ricotta, President of Vestas for Latin America, highlighted the strategic importance of the deal: “Receiving Casa dos Ventos’ trust once again for a project of this magnitude is a great source of pride for us. It is an honor to support a partner that shares the same ambition: to develop projects that drive the energy transition, expand access to clean energy, and foster socio-economic growth.”
This latest contract builds on a robust eight-year relationship between the two companies, which has previously delivered landmark projects such as the 1.3 GW Rio do Vento and Babilonia Centro clusters.
