A unipar announced a new investment billionaire in solar power plants em Mato Grosso do Sul, consolidating a strategic partnership with the House of the Winds for the exploration of the Paraíso Solar Complex, in Paraíso das Águas. According to an article published by Campo Grande News on February 19th.The contract signed between the companies will last for 15 years and guarantees the petrochemical company the receipt of 33 megawatts. average solar energy, with an estimated start date of 2028.
The agreement also provides for the right to acquire a 9,8% stake in Ventos de São Norberto Energias Renováveis, the company responsible for the project. This move reinforces the company’s strategy of expanding its self-production of renewable energy and reducing operating costs at its industrial plants.
In total, Casa dos Ventos is investing R$ 5,12 billion in the construction of three solar power plants in the state, with a total capacity of approximately 1,5 gigawatts (GW), positioning Mato Grosso do Sul among the leading players in photovoltaic generation in the country.
Meet the Ceará Distributed Generation Front, a project created by solar energy entrepreneurs seeking to combat the regulatory disputes the sector has faced in recent years; the movement aims to reach the public to clarify doubts about Distributed Generation and strengthen solar energy for all with clearer rules.
TP-Link develops outdoor camera with solar panel and promises to revolutionize home security by creating energy autonomy and continuous surveillance in outdoor environments.
Inspection of solar panels receives a boost after preventive maintenance by Inmetro on the photovoltaic energy testing system in Brazil.
Solar energy installation in churches progresses, and the Diocese of Criciúma reaches 72% completion of the sustainable project, resulting in cost reduction and a positive environmental impact.
The Paraíso Solar Complex integrates three large projects distributed between Campo Grande, Paranaíba, and Paraíso das Águas. The first two plants will begin operating in June and July of this year, while the third unit is scheduled for September 2027.
The combined capacity of approximately 1,5 GW represents one of the largest solar power generation projects in the Midwest. According to the State Secretariat for the Environment, Development, Science, Technology and Innovation (Semadesc), the complex could supply approximately 63% of the current electricity consumption of Mato Grosso do Sul.
For uniparThe 15-year contract guarantees predictability in the supply of an average of 33 MW, reinforcing its energy security policy. The company already directs a large part of its energy mix towards renewable sources, and the new investment expands this commitment.
A House of the Winds, traditionally recognized for its work in wind energy, is realizing with this project its first complex entirely dedicated to solar energyThe investment of R$ 5,12 billion demonstrates confidence in the state’s potential for generating revenue and in the regulatory stability of the Brazilian electricity sector.
The three solar power plants strategically located in the state of Mato Grosso do Sul enhance regional competitiveness. The expectation is that Mato Grosso do Sul will become one of the ten largest solar energy producers in Brazil, reinforcing its already consolidated 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 to attract industries.
Since 2019 the unipar The company has been expanding its strategy of self-generating renewable energy. Currently, about 80% of the energy consumed by the company in Brazil already comes from self-generation.
With the new investment in solar power plants in Mato Grosso do Sul, the company will allocate approximately 192 MW on average to its factories in the country, which operate entirely on electricity 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 energy-intensive. Therefore, long-term solar energy contracts become strategic to ensure competitiveness and cost predictability.
In addition to the new project with Casa dos Ventos, Unipar already maintains joint ventures in wind power projects in Rio Grande do Norte and Bahia, as well as a stake in a solar complex in Minas Gerais. The partnership in Mato Grosso do Sul represents the company’s fourth joint venture in renewable energy generation in Brazil.
The growth of solar energy in Brazil is consistent. Data from the Brazilian Photovoltaic Solar Energy Association indicates that the country has surpassed the mark of 37 GW of installed capacity in solar power, including both centralized and distributed generation.
In this context, the investment led by Casa dos Ventos in Mato Grosso do Sul reinforces the expansion of centralized generation in the Midwest. The region has high levels of sunshine throughout the year, a determining factor for the economic viability of large solar parks.
The projected supply equivalent to 63% of the state’s consumption highlights the structural importance of the complex. This means greater regional energy security, reduced transmission losses, and the potential to attract new industrial ventures.
Unipar’s presence as a buyer of part of the energy produced ensures financial stability for the project and strengthens investor confidence in the sector.
Casa dos Ventos’ definitive entry into the solar segment expands its portfolio, which until now has been mainly concentrated on wind power projects. The 1,5 GW complex in Mato Grosso do Sul consolidates the company’s technological diversification strategy.
The 15-year contract with Unipar is fundamental to the project’s viability. Long-term contracting models are common in the renewable energy generation market, as they reduce risks and ensure financial returns over the lifespan of solar power plants.
The R$ 5,12 billion investment positions the project among the largest ever undertaken in the Brazilian solar sector. The scale allows for gains in operational efficiency and competitiveness in energy supply.
Furthermore, the project marks a new moment for the national energy transition, reinforcing the leading role of solar energy in the Brazilian electricity matrix.
Unipar’s new investment strengthens its environmental agenda and ESG strategy. Replacing traditional energy sources with solar power reduces indirect emissions and improves the company’s positioning with investors and customers.
From an economic standpoint, solar power plants in Mato Grosso do Sul are expected to generate direct and indirect jobs during construction and operation. Projects of this size typically require hundreds of workers in the initial phases and maintain specialized technical teams for continuous operation.
Energy diversification also reduces the vulnerability of the electrical system to periods of drought or price volatility. For the petrochemical industry, predictability is a significant competitive advantage.
By consolidating its presence in the Midwest, Casa dos Ventos strengthens the local supply chain and expands the energy infrastructure available for new industrial ventures.
The investment announced by Unipar in partnership with Casa dos Ventos represents a decisive step towards consolidating solar energy as a strategic driver of 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 to supply an average of 33 MW, the project reinforces Mato Grosso do Sul’s leadership in the renewable energy sector.
The expansion of self-generation, which already accounts for 80% of Unipar’s consumption in Brazil and will reach approximately 192 MW on average for its factories, demonstrates a commitment to efficiency, sustainability, and energy security.
The solar complex not only strengthens the state’s electricity grid, but also signals to the market that major Brazilian industries are accelerating their energy transition. Mato Grosso do Sul thus consolidates itself as a strategic hub for national renewable energy generation, while Unipar and Casa dos Ventos expand their relevance in the Brazilian solar energy landscape.
