Borumba Pumped Hydro Project

Queensland Hydro are progressing a long-duration pumped hydro energy storage project at Lake Borumba.


About the Project

The proposed Borumba Pumped Hydro Project is a 2,000 MW pumped hydro energy storage system at Lake Borumba, located in Imbil, west of the Sunshine Coast.

The existing lower reservoir (Lake Borumba) will be expanded with a new dam wall downstream from the current Borumba Dam. A second reservoir will be constructed at a higher altitude. An underground powerhouse will link the two reservoirs together. When electricity is required, water will be released from the upper reservoir through underground turbines via tunnels to the lower reservoir.

In June 2023, the Queensland Government announced $6 billion in funding to progress the Borumba Pumped Hydro Project. The total project cost is estimated to be $14.2 billion.

Pending successful planning and environmental approvals, the Project is targeting first power in 2030.

Hydro Studies Summary report available

The Department of Energy and Climate has released the Hydro Studies Summary report, summarising the government’s investigations into energy storage through their Queensland Hydro Study.

The report explains why pumped hydro is needed in Queensland’s future energy system and outlines the investigations and studies that led to Borumba being selected as a potential site for pumped hydro.

Queensland Hydro is committed to being transparent with our project communities. Our projects, if approved, will deliver a stable and reliable electricity supply for all Queenslanders as we transition to renewable energy.

The government report is available on the Department of Energy and Climate website. Click here to access it.

Questions about the report should be directed to the Department via [email protected]
