Unipar Expands Its Renewable Energy Strategy with New Investment in Solar Plants in Mato Grosso do Sul, in Partnership with Casa dos Ventos. The Solar Energy Project Foresees 1.5 GW of Installed Capacity and a 15-Year Contract.
Unipar announced a new billion-dollar investment in solar plants in Mato Grosso do Sul, consolidating a strategic partnership with Casa dos Ventos for the exploration of the Paraíso Solar Complex in Paraíso das Águas. According to an article published by Campo Grande News on February 19, the contract signed between the companies will last for 15 years and ensures the petrochemical company will receive 33 megawatts of average solar energy, with an estimated start in 2028.
Understand the Agreement Between Unipar and Casa dos Ventos
The agreement also provides for the right to acquire a 9.8% stake in the capital of Ventos de São Norberto Energias Renováveis, the company responsible for the project. This move reinforces the company’s strategy to increase its renewable energy self-production and reduce operational costs at its industrial plants.
In total, Casa dos Ventos is investing R$ 5.12 billion in the construction of three solar plants in the State, with an approximate total capacity of 1.5 gigawatts (GW), positioning Mato Grosso do Sul among the leaders in photovoltaic generation in the country.

Paraíso Solar Complex Expands Unipar’s Presence in Solar Energy
The Paraíso Solar Complex integrates three large projects distributed between Campo Grande, Paranaíba, and Paraíso das Águas. The first two plants will begin operations in June and July of this year, while the third unit is scheduled for September 2027.
The joint capacity of approximately 1.5 GW represents one of the largest solar generation projects in the Midwest. According to the State Department of Environment, Development, Science, Technology, and Innovation (Semadesc), the complex could supply approximately 63% of the current electricity consumption of Mato Grosso do Sul.
For Unipar, the 15-year contract ensures predictability in the supply of 33 MW on average, reinforcing its energy security policy. The company is already directing a large part of its matrix to renewable sources, and the new investment expands this commitment.
Billion-Dollar Investment from Casa dos Ventos Strengthens Mato Grosso do Sul
Casa dos Ventos, traditionally recognized for its work in wind energy, is undertaking this project as its first complex entirely dedicated to solar energy. The investment of R$ 5.12 billion demonstrates confidence in the state’s irradiation potential and the regulatory stability of the Brazilian electric sector.
The three solar plants strategically distributed across the southern Mato Grosso territory enhance regional competitiveness. The expectation is that Mato Grosso do Sul will rank among the top ten solar energy producers in Brazil, reinforcing its already established position in biomass generation from sugarcane and planted forests.
The new investment also diversifies the state’s economic base. Projects of this magnitude boost the local production chain, from the construction phase to operation, in addition to strengthening the energy infrastructure for attracting industries.
Unipar’s Self-Production Strategy and Impact on Electric Matrix
Since 2019, Unipar has been expanding its renewable energy self-production strategy. Currently, about 80% of the energy consumed by the company in Brazil already comes from self-generation.
With the new investment in solar plants in Mato Grosso do Sul, the company will allocate approximately 192 MW on average to its factories in the country, which operate entirely with energy from renewable sources. This volume reinforces operational stability and reduces exposure to fluctuations in the free energy market.
The production of chlorine, caustic soda, and PVC is highly intensive in electricity consumption. For this reason, long-term contracts in solar energy become strategic to ensure competitiveness and cost predictability.
In addition to the new project with Casa dos Ventos, Unipar already has joint ventures in wind projects in Rio Grande do Norte and Bahia, as well as participation in a solar complex in Minas Gerais. The partnership in Mato Grosso do Sul represents the company’s fourth joint venture in renewable generation in Brazil.
Mato Grosso do Sul Advances in the National Solar Energy Ranking
The growth of solar energy in Brazil is consistent. Data from the Brazilian Solar Photovoltaic Energy Association indicate that the country has surpassed the mark of 37 GW of installed capacity from solar sources, combining centralized and distributed generation.
In this scenario, the investment led by Casa dos Ventos in Mato Grosso do Sul reinforces the expansion of centralized generation in the Midwest. The region presents high insolation rates throughout the year, a determining factor for the economic viability of large solar parks.
The projected supply equivalent to 63% of state consumption highlights the structural relevance of the complex. This means greater regional energy security, reduced transmission losses, and potential attraction of new industrial ventures.
The presence of Unipar as a buyer of part of the produced energy ensures financial stability for the project and strengthens investor confidence in the sector.
Casa dos Ventos Expands Portfolio with 1.5 GW Solar Plants
The definitive entry of Casa dos Ventos into the solar segment expands its portfolio, which was previously focused mainly on wind projects. The 1.5 GW complex in Mato Grosso do Sul consolidates the company’s strategy for technological diversification.
The 15-year contract with Unipar is essential for the project’s viability. Long-term contracting models are common in the renewable generation market as they reduce risks and ensure financial returns over the solar plants’ lifetime.
The investment of R$ 5.12 billion positions the project among the largest ever undertaken in the Brazilian solar sector. The scale allows for operational efficiency gains and competitiveness in energy supply.
Additionally, the project signifies a new moment for the national energy transition, reinforcing the prominence of solar energy in Brazil’s electric matrix.
Sustainability, Industrial Competitiveness, and Economic Impacts
The new investment by Unipar strengthens its environmental agenda and ESG strategy. Replacing traditional sources with solar energy reduces indirect emissions and improves the company’s positioning with investors and customers.
From an economic perspective, solar plants in Mato Grosso do Sul are expected to generate direct and indirect jobs during construction and operation. Projects of this scale typically require hundreds of workers in the early phases and maintain specialized technical teams for continuous operation.
Energy diversification also reduces the electrical system’s vulnerability to drought periods or price volatility. For the petrochemical industry, predictability is a relevant competitive differential.
Casa dos Ventos, by consolidating its presence in the Midwest, strengthens the local supplier chain and expands the energy infrastructure available for new industrial ventures.
Unipar and Casa dos Ventos: A Milestone for the Expansion of Solar Energy in Brazil
The investment announced by Unipar in partnership with Casa dos Ventos represents a decisive step toward consolidating solar energy as a strategic vector for industrial growth and regional development.
With a total capacity of 1.5 GW, an investment of R$ 5.12 billion, and a 15-year contract for supplying 33 MW on average, the project reinforces Mato Grosso do Sul’s leadership in the renewable energy sector.
The expansion of self-production, which already accounts for 80% of Unipar’s consumption in Brazil and will reach about 192 MW on average allocated to its factories, demonstrates a commitment to efficiency, sustainability, and energy security.
The solar complex not only strengthens the state electric matrix but also signals to the market that large Brazilian industries are accelerating their energy transition. Mato Grosso do Sul thus consolidates itself as a strategic hub of national renewable generation, while Unipar and Casa dos Ventos enhance their relevance in the Brazilian solar energy landscape.
