On the right bank of the dam is the power station intake which receives water into six 9.6 m (31 ft) diameter penstocks which each feed a 700 MW Francis turbine-turbine in the underground power station. The drop in elevation from the intake to the turbine affords a maximum hydraulic head of 251 m (823 ft). Once discharged by the turbine, the water is sent down one of two 18 m (59 ft) diameter tailrace tunnels towards the river.[1]
