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.
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.
