Unipar forms strategic partnership with Casa dos Ventos to expand self-production of renewable energy

29 de maio, 2026

Expand the already consolidated renewable self-production strategy, maintaining energy predictability and discipline in capital allocation 

Unipar, a reference in the chemical and petrochemical sector — producing chlorine, caustic soda, and PVC and present in the sanitation, civil construction, textile, pulp and paper, food, pharmaceutical, and aluminum markets —, considered energy an essential input and a determining factor for competitiveness in its industrial operation. With factories in Camaçari (BA), Cubatão (SP), Santo André (SP), and Bahía Blanca (Argentina), the company sought to continue diversifying its energy matrix and reducing exposure to market volatility, while maintaining discipline in capital allocation.

 

At the time, Unipar already had three other joint ventures for renewable energy self-production — in the Tucano (BA), Cajuína (RN), and Lar do Sol (MG) complexes — responsible for supplying the Camaçari and Cubatão units, and its industrial units already operated with 100% renewable electricity. The challenge, therefore, was to further expand this strategy, with energy predictability and mitigation of market risks.

Fourth joint venture with Casa dos Ventos: 33 average MW for 15 years via Ventos de São Norberto, with supply starting in 2028 

Unipar signed an Electric Power Purchase Agreement for the acquisition of 33 average MW with Ventos de São Norberto Energias Renováveis, an entity of the Casa dos Ventos group. The contract has a term of 15 years, with the supply period expected to start in 2028.

Energy is an essential input for the chemical industry and a determining factor for competitiveness. With our fourth joint venture in renewable generation, we combine discipline in capital allocation and the efficiency of our operations. The initiative contributes to the diversification of the company's energy matrix and to reducing exposure to market volatility.

Says Rodrigo Cannaval, CEO of Unipar.

 

The signing of this contract occurred in the context of the creation of a new joint venture between Unipar and Casa dos Ventos — the fourth of its kind between the two companies. After fulfilling the precedent conditions, Unipar gained the right to an equity stake corresponding to 9.8% of the company's economic capital (referring to this new project).

In a challenging scenario for the sector, energy predictability is a significant differential. Self-production allows us to mitigate market risks, optimize costs, and strengthen the company's operational and financial resilience.

States Rodrigo Cannaval.

Approximately 192 average total MW to factories in Brazil and fourth consolidated renewable joint venture with Casa dos Ventos 

  • 33 average MW of renewable energy contracted, for 15 years;
  • With this project, Unipar will allocate approximately 192 average MW to its factories in Brazil, combining this and previous projects;
  • Fourth joint venture in renewable generation between Unipar and Casa dos Ventos;
  • Reinforcement of the strategy of 100% renewable electricity already in practice at the company's industrial units.

This agreement with Unipar reinforces our ability to structure customized self-production solutions for large industrial consumers, combining economic efficiency, energy security, and sustainability. We are supporting the Brazilian industry in its energy transition and decarbonization journey with solid, long-term projects.

Reiterates Lucas Araripe, executive director of Casa dos Ventos.
