Australia adds 9.6 GWh pumped hydro project to pipeline


From pv magazine ESS News site

BE Power plans to build the 800 MW Big G pumped hydro energy storage project with 12-hour storage duration at full output. The estimated AUD 2.3 billion ($1.5 billion) project is to be built at Mount Alma, about 55 km southwest of Gladstone, central Queensland.

BE Power said it selected the Big G project site for its natural reservoirs. It added that the natural topography could allow for “highly efficient energy storage and generation, maximizing gravitational potential energy without the need for extensive infrastructure.”

BE Power said the long-duration energy storage project could enhance energy reliability in the Gladstone region and play a crucial role in facilitating the transition from aging baseload coal power plants to renewable power sources such as solar and wind.

“It stands to significantly firm up local grid requirements, providing unparalleled support to the region’s energy infrastructure,” the company said, adding that the project could also deliver substantial economic benefits for the region during its construction and operation phases.

Construction is expected to commence in late 2027, with commercial operations anticipated to start in early 2033.

BE Power, which is also developing the 400 MW/4 GWh Big T pumped hydro project near Toowoomba in southeastern Queensland, said the concept study and initial environmental assessment for the Big G project have been completed. Applications to secure the necessary permits and approvals have been made and an Initial Advice Statement is being prepared for submission to the Queensland Office of the Coordinator General.

The Big G proposal is one of a number of pumped hydro projects in the pipeline in Queensland, with the state government having identified the technology as the centerpiece of its 10-year Energy and Jobs plan. The plan aims to have 70% of the state powered by renewable energy by 2032 and 80% by 2035.

The state government-owned Queensland Hydro is developing two major projects – one in the Pioneer Valley near Mackay in central Queensland and the other at Borumba near Gympie. Key contracts for 5 GW/120 GWh Pioneer-Burdekin project have already been awarded while the business case for the 1 GW/24 GWh Borumba scheme has been signed off by the government, and the environmental approvals process is underway.

Other projects in the pipeline include the proposed 2 GW/20 GWh Mount Rawdon pumped hydro project being developed near Bundaberg by Sydney-based company Evolution Mining. The most advanced of the projects is the 250 MW/2 GWh facility being built by Genex near Kidston, about 270 km north-west of Townsville in northern Queensland.

In its latest update, Genex said the excavation works for the underground powerhouse had been completed and underground fit-out works had started, with the facility on schedule to start generating in early 2025.

Queensland is also home to the 570 MW Wivenhoe pumped hydro facility, which commenced operations in 1984.
