Design and operation
Water for the scheme is derived from the Aït Ouarda Dam on the El Abid River at , just downstream of the Bin el Ouidane Dam. Water from the dam is pumped up in elevation via Step 1 to the Upper Afourer Reservoir at which has a capacity of and lies at an elevation of above sea level. Step 1's power and pumping station contains 2 x 172.5 MW reversible Francis turbines. From the upper reservoir, water can be released back to Step 1 for power generation or released down in elevation to the Lower Afourer Reservoir at which lies at an elevation of and also has a capacity of . The power station at the lower reservoir, Step 2, contains 2 x reversible Francis turbines From the lower reservoir, water can be pumped back into the upper reservoir or released into a canal near Afourer for use in irrigation.
