Queensland Hydro has received Commonwealth regulatory approval to undertake exploratory works for the proposed Borumba pumped storage hydro project, marking a key step in the project’s development.

Approval has been granted under the Commonwealth Environment Protection and Biodiversity Conservation Act (EPBC Act) and allows Queensland Hydro to carry out geotechnical investigations to confirm site conditions. Data collected through the exploratory works will inform detailed design development and a revised business case for the project.

Subject to state approvals, Queensland Hydro plans to commence the next phase of the Borumba pumped storage project in 2026.

Queensland Hydro continues to revise the project’s business case and commercial assessment. The exploratory works are intended to reduce risk by providing early technical information prior to any decision on main works construction.

Queensland Hydro Executive Chair Mark Irwin said long-duration pumped hydro would play a critical role in Queensland’s future energy system.

“The Borumba Pumped Hydro Project is a critical component of Queensland’s future energy mix, and the Commonwealth regulatory approval is a significant step forward in its development,” Irwin said. “The proposed exploratory works will support the revised business case for the Borumba Project, with data collected able to support any future configuration.

“Delivering major infrastructure projects requires meticulous planning to avoid unforeseen risks. One of the most effective strategies for achieving this is undertaking comprehensive exploratory works before finalising designs and commencing future main works construction activities.

“If the Borumba Project proceeds to main works construction, this phase will require further Commonwealth and State approvals.

“In addition, and aligned to our commitments to local benefits, Queensland Hydro will be closely engaging with local suppliers and the community on the exploratory works program.”

The Commonwealth approval follows a public consultation process conducted in early 2025. Submissions received during the consultation, along with Queensland Hydro’s responses, were considered as part of the assessment by the Department of Climate Change, Energy, the Environment and Water.

The approval includes conditions specific to the scope of the exploratory works. These include limits on disturbance, implementation of environmental management plans, land security and restoration in accordance with the Offset Area Management Plan, and additional compliance requirements. Some conditions must be met prior to the commencement of works, while others apply throughout the exploratory phase.

Queensland Hydro is required to report on compliance with approval conditions and management plans. Compliance reports will be published on the Queensland Hydro website.
