Kidston Pumped Storage Hydro project
October 1 @ 5:30 pm - 7:30 pm AEST
Overview
The Kidston Pumped Hydro project represents an innovative approach to renewable energy storage through the transformation of abandoned mining infrastructure. Located northwest of Townsville in Queensland, Australia, this pioneering 250MW facility developed by Genex Power demonstrates how former gold mine pits can be repurposed as upper and lower water reservoirs for pumped storage hydropower.
The project showcases significant tunnelling and underground construction expertise, featuring 235-metre deep shafts and extensive tunnel networks that form the critical waterways connecting the reservoirs. At the heart of the facility lies an underground powerhouse cavern housing two reversible pump turbines, representing sophisticated underground engineering in challenging geological conditions. The scope encompasses a six-kilometre dam at the upper storage level and requires the pumping of over 25 billion litres of water from the lower storage to enable safe completion of underground construction works. A 187-kilometre transmission line connects the facility to the national grid via a substation near Townsville.
The project demonstrates comprehensive engineering integration across multiple disciplines, including detailed design of both dam and underground infrastructure, powerhouse engineering, and construction supervision of tunnelling operations. Notably, the project employed collaborative BIM modelling with all stakeholders to optimise the entire scheme design and construction coordination.
As Australia transitions toward renewable energy, pumped hydro storage addresses the critical challenge of energy storage and grid stability. The Kidston project serves as a prototype for numerous large-scale pumped hydro developments planned across Australia and New Zealand, with projects totaling over 4GW in the development pipeline. This presentation will explore the tunnelling challenges, underground construction methodologies, and innovative engineering solutions that make the repurposing of mining infrastructure a viable model for sustainable energy storage development.
