Mequinenza Dam
The 263rd tallest dam in the world
Mequinenza Dam (Spanish: Presa de Mequinenza) is a concrete gravity dam in the province of Zaragoza, Spain. It impounds the Ebro creating a large reservoir, which is called Mar de Aragón. About 35 km downstream of Mequinenza dam is Ribarroja dam. Empresa Nacional Hidroeléctrica del Ribagorzana S.A. (ENHER) was mandated in 1955 by Instituto Nacional de Industria (INI) to build two dams on the Ebro near Mequinenza and Ribarroja. Work on Mequinenza dam started in 1957. The filling of the reservoir began in December 1965. The power plant was operational in 1964 (1966). ENHER was acquired by Endesa in 1999.
