In Ribeiradio, the main stage of the scheme, a nominal flow of 125m3/sec will be utilized with a net head of 65m. andritz will supply a Francis turbine with a runner diameter of 3.7m and a nominal output of 77MW. The Ermida power station will be equipped with two double-regulated compact axial turbines (1,950mm runner diameter and a nominal output of 3.8MW each). The scope of supply for both hydropower plants also includes synchronous generators, control systems, hydromechanical equipment, as well as electrical and mechanical auxiliary systems.
