The Allal al Fassi Dam is an embankment dam located 18 kilometres (11 mi) northeast of Sefrou on the Sebou River in the Fès-Boulemane region of Morocco. Completed in 1991, it provides water for irrigation and hydroelectric power production. The dam was named after the famous Moroccan Allal al-Fassi.[2]

Power station

The dam's hydroelectric power station is located 18 kilometres (11 mi) to the north on the southern bank of the Idriss I Dam's reservoir. Water reaches the power plant after being diverted by the Allal al Fassi Dam via an intake on the right bank of the reservoir. It flows through a 15.45 kilometres (9.60 mi) long tunnel before reaching a compensating basin. From the basin, water is sent through pipelines and finally penstocks to 3 x 80 megawatts (110,000 hp) Francis turbine-generators. Once used for power generation, the water is discharged into the Idriss I Reservoir. About 300 million cubic metres (240,000 acre·ft) of water is transferred through the power station annually. The power station was commissioned in 1994 and generates 220 gigawatt-hours (790 TJ) on average annually.[2]
