The scheme provides for up to 27.6 gigawatt-hours (99 TJ) of electricity storage in the form of 27,000,000 cubic metres (950,000,000 cu ft) of water. The water is pumped to
Driekloof during times of low national power consumption (generally over weekends) and released back into Kilburn

equipment is located between
Driekloof Dam and Kilburn Dam. Since the Driekloof Dam/Sterkfontein Dam also forms part of the Tugela-Vaal Water Project some of the water pumped to Driekloof Dam might end up flowing to the
