Casa dos Ventos Sells Solar Power to Aegea

• Casa dos Ventos will power Aegea’s sanitation units with 13.89MW solar energy, covering 80% and 60% demand for key operations—deliveries begin in 2027.

Casa dos Ventos, a Brazilian renewable energy developer, has agreed to supply Aegea’s sanitation units with 13.89 average megawatts of solar electricity. The deal covers power to support the companies’ operations through long-term self-production arrangements tied to consortium leasing.

Deliveries are set to start in 2027. The contract is expected to meet about 80% of electricity demand for Aguas do Para and roughly 60% of consumption for Aguas do Piaui. The project marks Casa dos Ventos’ second partnership with a Brazilian company in the basic sanitation sector.

How will Casa dos Ventos’ solar power supply Aegea’s sanitation units from 2027?

• Starting in 2027, Casa dos Ventos’ solar generation will be channelled through long-term self-production (consortium-led leasing) arrangements, allowing Aegea to use contracted renewable electricity directly for running its sanitation assets.
  
• The supplied power is sized to cover a major share of Aegea’s operational electricity needs—around 80% for Aguas do Pará and about 60% for Aguas do Piauí—reducing the volume these utilities must procure from the grid.
  
• Solar power will typically feed processes that consume electricity continuously or on a daily cycle, such as pumping and distribution activities that are common across water and wastewater services.
  
• Because the contract is structured for long-term supply, it is intended to provide greater predictability on energy costs and supply security for operating sites covered under Aegea’s sanitation concessions.
  
• By shifting a significant portion of electricity consumption to on-site/self-production linked to solar assets, Aegea can lower exposure to future volatility in conventional power prices and dispatch-related risks.
  
• The use of renewables for sanitation operations supports sustainability goals by cutting associated greenhouse-gas emissions relative to electricity sourced primarily from fossil-based generation.
  
• This arrangement aligns with how Brazilian sanitation operators often manage energy supply: securing dedicated renewable electricity volumes tied to specific operating entities and their service areas.
  
• Operationally, deliveries beginning in 2027 indicate a development-and-commissioning timeline that allows time for solar plant construction, grid connection, and ramp-up to the contracted output profile.
  
• The deal expands Casa dos Ventos’ footprint in Brazil’s basic sanitation market, reinforcing its growing role as a provider of renewable power solutions to utilities operating essential public services.
• As a “second partnership” in the sanitation segment, it signals continuity in the commercial approach—repeatable contract structures for supporting sanitation utilities with substantial portions of their electricity demand.
