Iowa Hill Pumped Storage Project
Underground powerhouse and headrace works for a pumped storage hydroelectric facility.
Deep underground powerhouse, headrace and tailrace engineering in mountainous terrain.
Complex water-transient behaviour and hard-rock cavern excavation were modelled in parallel, feeding a coordinated design that protected equipment during rapid power transients.
