Santo Antônio Dam, Hydroelectric power station on Madeira River, Rondônia, Brazil.
Santo Antônio is a hydroelectric facility on the Madeira River in Rondônia that spans 3,100 meters with 50 bulb turbines generating electricity for southeastern Brazil. The structure was built to supply power to multiple cities and industrial centers across the region.
Construction started in 2008 at Porto Velho and reached full operational capacity by the end of 2016 with all turbines functioning. The project was part of a broader effort to increase Brazil's hydroelectric energy generation.
The facility changed how local communities used the river for fishing and farming, reshaping daily routines that families had followed for generations.
The facility itself is not accessible to the public, but viewing areas from nearby roads offer views of the structure and reservoir. Early morning or late afternoon provides the best light for photography and observation.
The facility includes two fish passages and a navigation lock system designed to support migrating fish species and allow river traffic to continue. These features make it a noteworthy example of balancing energy production with river ecology.
