Ingula Pumped Storage Scheme

The Ingula Pumped Storage Scheme is an impressive 1,333 MW hydropower scheme, designed to augment the National Grid during peak power usage periods. This engineering innovation was a design created by a three-way joint venture among Knight Piésold, Royal HaskoningDHV, and GIBB (Pty) Ltd. The scheme is characterized by a lower reservoir (Bramhoek Dam), an upper reservoir (Bedford Dam), waterway tunnels, design flows, a 460 m head with 80 m submergence, four 333 MW Francis pump turbines, an access tunnel of 8 m x 8 m, and a powerhouse cavern with dimensions of 190 m x 30 m x 40 m.

Knight Piésold’s Role

Knight Piésold was responsible for project management, dam type selection, geotechnical investigations, dam design, tender documents, construction supervision, and the Operations and Maintenance Manual.
