The left tunnel will be used as discharge for the main spillway, while the right tunnel will normally be used as a power tunnel to supply water to the two power turbines of 25 MW each. For inflows in excess of 1000 cubic meters per second, the right tunnel also serves as an auxiliary spillway; (d a power house,where the Project's electromechanical works, controls and related equipment are located; and (e) a 200 km long 161 kV transmission line from the hydropower site with Freetown,where a161/33 kV substation is located.
