Mequinenza Dam (Spanish: Presa de Mequinenza) is a concretegravity dam in the province of Zaragoza, Spain. It impounds the Ebro creating a large reservoir, which is called Mar de Aragón.[1] About 35 km downstream of Mequinenza dam is Ribarroja dam.
Empresa Nacional Hidroeléctrica del Ribagorzana S.A. (ENHER) was mandated in 1955[2][3] by Instituto Nacional de Industria (INI) to build two dams on the Ebro near Mequinenza and Ribarroja. Work on Mequinenza dam started in 1957.[1] The filling of the reservoir began in December 1965.[2] The power plant was operational in 1964[3][4] (1966[5]). ENHER was acquired by Endesa in 1999.[6]
Mequinenza Dam is a 79 m tall (height above foundation) and 461 m long gravity dam with a crest altitude of 124 m. The volume of the dam is 1,100,000 m3. The dam features a spillway with 6 gates over the dam (maximum discharge 11,000 m3/s) and one bottom outlet (maximum discharge 160 m3/s).[7]
Reservoiredit
At full reservoir level of 121 m.a.s.l. the reservoir has a surface area of 75.4 km2, a total capacity of 1.53 billion m3 and a length of almost 110[2][3] km. The average width of the reservoir is about 600 m, its maximum (average) depth is 62 (20) m.[5]
Power plantedit
The power plant contains 4 Francis turbine-generators. The initial nameplate capacity was 81 MW each. The turbines, generators and transformers were refurbished from 2007 until 2010 raising the capacity of the new machines to 96 MW each.[4] Maximum flow is 150 m3/s per turbine.[5]
