Aguieira Dam, Arch dam and hydroelectric station in Coimbra District, Portugal
The Aguieira Dam stretches 400 meters across the Mondego River, reaching a height of 89 meters and creating a reservoir with a surface area of 20 square kilometers.
Construction of the Aguieira Dam commenced in 1972, and after nearly a decade of development, the facility began generating hydroelectric power in 1981.
The creation of the Aguieira reservoir transformed the local landscape, submerging the villages of Breda and Foz do Dão, leading to significant changes in community settlement patterns.
The power station houses three Francis turbine-generators, each producing 112.4 MW, contributing to an annual electricity generation of 209.9 gigawatt-hours for Portugal's power grid.
The dam operates as both a conventional hydroelectric facility and a pumped-storage station, allowing water to be recycled between reservoirs for optimal energy management.
