Casa dos Ventos, one of Brazil’s largest renewable energy firms, is tapping an American company to supply 1.5 gigawatts (GW) of solar trackers and tracking systems for a portfolio of four new solar and solar-and-wind hybrid utility-scale projects.
The projects, 117 megawatt (MW) Babilônia Sul, Babilônia Centro (226 MW), Seriemas (540 MW), and Rio Brilhante (680 MW), are located in the municipalities of Morro do Chapéu and Várzea Nova in Bahia, and Rio Brilhante and Seriemas in Mato Grosso do Sul. Nextracker will furnish the sites with its NX Horizon-XTR all-terrain solar trackers and NX Horizon solar tracker systems.
“Securing a multi-project commitment from a renewable energy leader like Casa dos Ventos reflects the growing importance of trusted partnerships when it comes to performance and long-term reliability in today’s solar industry,” said Alejo Lopez, vice president, Nextracker Latin America. “We are honored to support Casa dos Ventos with solutions that are engineered for resilience and optimized for each of its unique environmental site conditions,” said Lopez.
Three of the four new projects—Babilônia Sul, Babilônia Centro, and Seriemas—are deploying NX Horizon-XTR all-terrain tracker systems, purpose-built for hilly and undulating landscapes, providing significant savings on earthworks and grading. All sites will incorporate Nextracker’s TrueCapture yield management and control system, which uses advanced sensor technology and machine learning to continuously adjust tracker angles to ensure expected energy generation in dynamic lighting and uneven terrain conditions.
Casa dos Ventos Adding Solar to its Portfolio
Brazilian Casa dos Ventos, which develops, builds, and operates renewable energy generation projects, particularly wind, is now integrating solar into its renewable portfolio, a growing trend among Brazilian developers aiming to optimize grid connections and project returns.
The agreement with Nextracker is part of Casa dos Ventos’s first utility-scale solar deployment. It is also a significant step in its strategy to develop hybrid power plants that integrate solar and wind at shared grid interconnection points.
By combining complementary energy sources, infrastructure, and available land, hybrid plants like the ones Nextracker is supplying its technology for can optimize grid capacity, a growing advantage in Brazil’s constrained transmission landscape.
“Partnering with Nextracker gives us confidence in the long-term performance and reliability of our projects,” confirmed Thiago Rezende, construction and operations director at Casa dos Ventos.
Casa dos Ventos is responsible for the largest wind measurement campaign ever undertaken globally, and the company has developed one in every four wind projects currently operating in Brazil. Casa dos Ventos holds the largest portfolio of wind and solar projects in the country, with approximately 35 GW of capacity. Recently, Casa dos Ventos announced a joint venture with TotalEnergies to jointly develop, build, and operate its renewable portfolio in Brazil, including hydrogen and green ammonia projects.
Nextracker’s Footprint in Brazil
Nextracker has a strong and growing presence in utility-scale and distributed generation solar projects in Brazil and across Latin America, with over 130 GW shipped in over 40 countries worldwide. Brazil, which already sources over 80% of its electricity from renewables, has committed to achieving net-zero greenhouse gas emissions by 2050 and aims to significantly expand its solar capacity. According to ABSOLAR, Brazil is expected to add 13.2 GW of new solar capacity in 2025, reaching a total of 64.7 GW by the end of the year. Investments in the solar sector are projected to exceed $7 billion (R$39.4 billion), generating over 396,000 jobs and contributing more than $2.3 billion (R$13 billion) in tax revenue.
Considering its localized manufacturing capability, regional engineering expertise, and strong partnerships with leading developers, Nextracker says it is uniquely positioned to support the clean energy transition while contributing to local content and regional economic development.
