Crestuma Dam, Hydroelectric power station on Douro River, Portugal
The concrete gravity dam stretches 470 meters across the Douro River with a height of 25.5 meters and includes eight discharge gates for water management.
Construction of the Crestuma Dam began in 1976 and reached completion in 1985, marking a new chapter in Portugal's energy infrastructure development.
The dam represents an intersection between industrial development and river navigation, enabling cargo ships up to 83 meters long to traverse the waterway.
Three Kaplan turbine generators produce 117 megawatts of renewable energy while maintaining water levels for navigation and flood control purposes.
The facility manages a reservoir of 110 million cubic meters while featuring a navigation lock system that supports regional maritime transportation.
