Kidston pumped storage hydro project
At a glance
GHD is delivering the engineering services contract for the design and construction of the ground-breaking 250 MW Kidston Pumped Storage Hydro project in a joint venture with Mott MacDonald as part of Queensland’s AUD 62 billion clean energy plan.
The project consists of a six kilometre-long dam on the upper storage, 235m deep shafts and tunnels forming the waterways, an underground powerhouse cavern housing two reversible pump turbines, and a surface switchyard. A 187km transmission line to a substation near Townsville will feed power into the national grid. More than 25 billion litres of water will be pumped out of the lower storage to enable the underground works to be completed once the upper dam is complete.
Over the last 18 months detailed design has been completed across a range of services including:
- Detailed design of the dam and underground works
- Powerhouse design
- Supervision of dam construction and tunnel development
- Cocreation and development with all stakeholders of a BIM model for the entire scheme
- Completion of electrical design for balance of plant
Kidston (250MW) will be the first of numerous large-scale pumped hydro and water infrastructure schemes planned in Australia and New Zealand including:
- Pioneer-Burdekin Pumped Hydro – when constructed, the scheme will be the largest pumped hydro energy storage in the world, producing a proposed 5 GW of 24-hour storage. GHD is providing stakeholder, Indigenous and community engagement services for the project, located in Queensland.
- Borumba Pumped Storage Project – GHD is providing engineering services for the development of the lower storage dam as part of the proposed 1,000 MW Pumped storage project in Queensland.
- In New Zealand, GHD is working as part of the Te Rōpū Matatau, alongside two other consultancies (Mott MacDonald and Boffa Miskell), to carry out an engineering and environmental feasibility investigation into a pumped hydro storage scheme at Lake Onslow in the Otago region.
- GHD has also completed the concept designs for 3.7GW and pre-feasibility studies for 3.1GW of Pumped Hydro Energy Storage Projects.
