Assessing long-duration storage to support Queensland's energy system.
Pumped hydro plays an important role in the energy mix by capturing and storing excess energy when wind and solar are generating and releasing it back to the grid when it is needed – supporting reliability and resilience in the broader supply system.
As outlined in the Roadmap, QIC was tasked with undertaking a full commercial assessment of delivery options for the proposed Big T, Borumba, Capricornia and Mt Rawdon pumped hydro projects to ensure a coordinated, state-led approach to long-duration hydro energy storage.
QIC's assessment involved a consistent evaluation framework aligned with the Energy Roadmap's objectives of affordability, reliability and sustainability, as well as delivering economic benefit to Queensland.
The assessment found there is a system need for pumped hydro from the mid-2030s and as per the State Budget 2026-27, QIC is now undertaking further assessment of Borumba and Capricornia with consideration of broader benefits, including system reliability and resilience, value for money for the State and water security outcomes for communities, agriculture and other industry.
