The largest hydroelectric power plant in South Africa is the 1000 megawatt Drakensberg Pumped-Storage Facility, part of a larger scheme of water management that brings water from the Tugela River into the Vaal watershed. The Drakensberg Pumped Storage Scheme is in the Northern Drakensberg mountains in KwaZulu-Natal, close to the town of Bergville. The station is unique as apart from the dam wall, lift shaft buildings and transmission lines, all installations are 150 meters underground. A pumped storage scheme generates electricity during peak hours, which is everyday when the demand of electricity rises. During the off-peak periods Drakensberg uses its reversible turbines to pump the water back to the upper reservoir, readying the system for peak periods.
