The Paulínia Verde thermal power plant marks Brazil’s initial integration of biomethane-fueled generation into the national grid under a 10-year capacity reserve contract. The project demonstrates the commercial viability of urban waste-to-energy conversion while positioning São Paulo state as a reference point for circular economy applications in power generation. The facility’s location in a major consumption center and its capacity to avoid 80,000 tonnes of CO2-equivalent emissions annually establishes a template for similar developments across metropolitan regions.
