The Ingula Pumped Storage Scheme broadly consists of two dams and an interconnecting tunnel network that will eventually generate 1 400 megawatts of hydroelectricity. Bedford Dam is a mass gravity earth/rockfill design with concrete cladding on the upstream side. Bedford is situated on the Free State escarpment and is more than 400 m higher than the Bramhoek Dam situated in KwaZulu-Natal. The bottom dam (Bramhoek) is a mass-gravity rollcrete concrete dam situated in the Bramhoek spruit.
