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, four 333 MW Francis pump turbines, an access tunnel, and a powerhouse cavern.
Knight Piésold assisted with the geotechnical investigations, tender design, procurement, detailed engineering, and construction and commissioning supervision.
Engineering services were provided in three phases:
Phase 1: Project Optimization
Phase 2: Tender Design
Phase 3: Construction Stage Design, Monitoring, Supervision, and Sign-off
