A major construction milestone has been reached at the Kidston pumped storage hydropower project with the successful installation of the spiral case and stay ring assembly for Unit 2 at the end of April 2025.
The spiral case was lifted into place as scheduled, marking a key step in the project’s installation phase. The work was carried out by EPC contractor JV (John Holland and McConnell Dowell), with support from ANDRITZ technical advisors.
Kidston is Australia’s first pumped storage hydropower project to be developed by the private sector. Once complete, it will be the country’s third-largest electricity storage facility, aimed at improving grid stability and supporting renewable energy integration.
ANDRITZ signed a contract in 2021 to design, manufacture, and supply the electromechanical equipment for the project. The company described the successful placement of the first of two spiral cases as evidence of effective planning and execution.
The project continues to progress toward its completion, with further installation milestones expected in the coming months.
