Project description 
The 1334 MW Ingula Pumped Storage Scheme consists of an upper reservoir and a lower reservoir. The distance between the two reservoirs is in the order of 6 km and the elevation difference is approximately 470 m. Two 6,6 m dia (nominal) penstocks under 450 m (nominal) head, driving 4N° 333 MW Francis Pump Turbines, with water exiting through a single 9,0 m dia (nominal) tailrace. The underground power station is a 150 m x 25 m main cavern together with a 160 m x 15 m transformer hall.
