The Queensland Government will invest more than $48 million for a major overhaul at Wivenhoe Pumped Hydro Power Station—the state’s only operational pumped hydro generator.
The investment will ensure each of Wivenhoe’s 285MW turbines will be overhauled across the next two years to maintain the station’s reliability and efficiency.

This follows Wivenhoe’s record-breaking performance in the last financial year, when the station generated more than 218 gigawatt hours in the fourth quarter alone—the highest quarterly output in its 40-year history.
Queensland Treasurer and Minister for Energy David Janetzki said, “These major works will keep this pumped hydro supporting Queensland’s electricity network for decades to come.
“Wivenhoe’s record performance shows the critical role smaller, more manageable pumped hydro plays in providing affordable and reliable energy.
“Alongside this, thanks to an initial $50 million investment by the Crisafulli Government, CleanCo is investigating the feasibility of pumped hydro at Mount Rawdon, repurposing the existing gold mine into a sustainable energy asset.”
CleanCo CEO Tom Metcalfe said the program of works would begin in May 2026.
“CleanCo is the custodian of Queensland’s only operational pumped hydro at Wivenhoe, and we’re proud to be getting more out of this asset than ever before,” Metcalfe said.

“In the last year we’ve achieved record generation from Wivenhoe, and these maintenance works will make sure the station can keep delivering at that level well into the future.
“We’re also progressing work at Mount Rawdon, because smaller, more manageable pumped hydro is central to Queensland’s energy future and directly aligned with the Crisafulli Government’s priorities to deliver reliable, affordable and sustainable energy.”
