Atacadão Advances in Energy Transition by Partnering with Casa dos Ventos for Self-Production via Solar Consortium. Project with Photovoltaic Plants Ensures Clean Energy and Reduces Operational Costs
On October 10, 2025, the announcement of the partnership between Casa dos Ventos and Atacadão marks a strategic step in the energy transition of the Brazilian retail sector.
According to a report published on the MegaWhat website, the agreement provides for the supply of 50 MW average of solar energy through a solar consortium, focusing on clean energy and reducing operational costs.
Strategic Partnership Between Casa dos Ventos and Atacadão
The initiative was announced by the MegaWhat portal, highlighting that the contract between the companies will be made possible through a solar consortium, a model that allows for shared self-production of energy. The project will be powered by photovoltaic plants developed by Casa dos Ventos, one of the leaders in sustainable solutions in Brazil.

The union between Casa dos Ventos and Atacadão strengthens the commitment to corporate sustainability. In addition to reducing the carbon footprint, the project aims to ensure greater predictability of energy costs and independence from the conventional electrical grid.
What Are 50 MW Average and Why Does It Matter?
The term “50 MW average” refers to the average continuous energy generation over a period. In practical terms, this capacity is sufficient to supply around 180 thousand Brazilian households per month, considering an average consumption of 200 kWh per household.
For Atacadão, this energy will be used to supply part of its operations in stores, distribution centers, and administrative offices, reducing dependence on the conventional electrical grid and costs with energy tariffs. Energy self-production is a strategic solution for large consumers.
Casa dos Ventos: A Reference in Photovoltaic Plants and Clean Energy
Founded with the purpose of accelerating the energy transition in Brazil, Casa dos Ventos has a portfolio of more than 33 GW in wind, solar, and hybrid projects in operation or development.
The company is recognized for its innovative performance in the free energy market, offering customized solutions for large consumers.
In addition, the company has invested heavily in measurement technologies and energy intelligence, ensuring greater predictability and efficiency in energy generation and distribution. Casa dos Ventos is a reference in sustainable and competitive projects.
Atacadão Bets on Clean Energy as a Competitive Differentiator
Atacadão, the largest Brazilian wholesaler by number of stores and revenue, has adopted sustainable practices as part of its business strategy. The partnership with Casa dos Ventos reinforces the company’s commitment to ESG principles (environmental, social, and governance), especially in the environmental axis.
According to the company’s own data, Atacadão has more than 415 units in operation in Brazil, and energy consumption is one of the main operational costs.
By investing in self-production through photovoltaic plants, the company seeks not only savings but also greater control over its energy matrix. Sustainability and savings go hand in hand in Atacadão’s strategy.
How the Solar Consortium Between Casa dos Ventos and Atacadão Works
The solar consortium model allows companies to share the generation of energy from the same plant, proportional to their participation in the venture. In the case of the partnership between Casa dos Ventos and Atacadão, the energy will be generated in dedicated photovoltaic plants and injected into the electrical grid, being compensated in Atacadão’s consumption units.
This system is regulated by the National Electric Energy Agency (ANEEL) and has gained popularity among large consumers for offering advantages such as:
- Reduction of electricity costs
- Budget predictability
- Contribution to decarbonization targets
- Enhancement of the brand among consumers and investors
The solar consortium is an intelligent solution for companies seeking energy efficiency.
Clean Energy and the Positive Environmental Impact
The generation of clean energy through renewable sources such as the sun directly contributes to the reduction of greenhouse gas emissions. According to the Ministry of Mines and Energy, the Brazilian electric sector already has one of the cleanest energy matrices in the world, with more than 80% of generation coming from renewable sources.
With the entry of more projects like that of Casa dos Ventos and Atacadão, this participation is expected to grow, consolidating Brazil as a global leader in sustainable energy.
Furthermore, the adoption of solar energy avoids the use of fossil fuels, reduces air pollution, and promotes the rational use of natural resources. Clean energy is synonymous with environmental responsibility and competitiveness.
The Free Energy Market in Expansion
The partnership between Casa dos Ventos and Atacadão occurs at a time of strong expansion of the free energy market in Brazil. According to data from the Electric Energy Trading Chamber (CCEE), the number of free consumers grew over 25% in 2025, driven by regulatory changes and greater environmental awareness.
Companies that adopt the free market can negotiate directly with generators and marketers, obtaining more advantageous and customized conditions. The solar consortium is one of the most sought-after alternatives in this context.
The free market is the future of corporate energy in Brazil.
Studies and Projections for the Photovoltaic Plant Sector
According to the Brazilian Photovoltaic Solar Energy Association (ABSOLAR), Brazil has surpassed the mark of 40 GW of installed capacity in solar energy in 2025, consolidating itself as one of the ten largest markets in the world.
The expectation is that this number will continue to grow, driven by:
- Tax and regulatory incentives
- Decrease in equipment prices
- Increased demand for sustainable solutions
- Strategic partnerships like that of Casa dos Ventos and Atacadão
The growth of photovoltaic plants is essential for national energy security.
Strategic Impact and Future of the Partnership
The partnership announced between Casa dos Ventos and Atacadão represents a milestone in the integration between the retail sector and the generation of clean energy. With the supply of 50 MW average through photovoltaic plants, the project reinforces the trend of self-production and energy efficiency in the Brazilian market.
This initiative strengthens Brazil’s leadership in the global energy transition.
In addition to economic benefits, the project contributes to environmental sustainability, the enhancement of the involved brands, and the advancement of the free energy market.
The solar consortium model proves to be a viable, scalable, and strategic alternative for companies wishing to position themselves responsibly and competitively.
