Pumped Hydro

The Queensland government has awarded two key contracts for what it says will be the largest pumped hydro energy project in the world, with the proposed 5 GW/120 GWh Pioneer-Burdekin pumped hydro energy storage system to form a cornerstone of the state’s energy transition.

Queensland has laid out an ambitious vision for the state’s energy future, releasing draft legislation that calls for an additional 22 GW of new wind and solar projects by 2035, supported by at least 12 GW of storage, firming and dispatchable technologies including grid-scale batteries and pumped hydro storage.

The beleaguered Snowy 2.0 pumped hydro project has been hit with fresh construction delays and added cost blowouts with concerns the multi-billion-dollar project may now not reach full commercial operation until late 2029.

The New Zealand government will further investigate the viability of establishing a pumped hydroelectric facility on the South Island that would provide up to 8.5 TWh of annual generation and storage capacity to support the nation’s transition to 100% renewable electricity generation.

Danish investment firm Copenhagen Infrastructure Partners has sharpened its focus on long-duration storage in Australia, announcing it has acquired the proposed Bowen Renewable Energy Hub project that is expected to combine 1.4 GW of pumped hydro storage with huge solar and wind generation.

Construction has officially commenced on Western Australia’s first pumped hydro project but the state government has indicated it won’t be the last, hinting that the 1.5 MW renewables microgrid being built at Walpole could serve as a blueprint for the roll out of similar projects both nationally and overseas.

With construction underway on a $295 million (USD 197 million) transmission project to connect the landmark Kidston Clean Energy Hub to the grid in far north Queensland, developer Genex Power has announced plans to boost the generation capacity of what is already Australia’s largest hybrid energy project combining wind, solar and pumped hydro.

The New South Wales government has received bids for more than 5.5 GW of wind and solar projects, along with more than 2.5 GW of long-duration storage projects, in response to its first tender to secure renewable projects to transform its coal-reliant energy system.

The Australian federal government’s $20 billion (USD 12.6 billion) Rewiring the Nation program has kicked off with billions allocated to support two major interconnector transmission projects.

A plan to build a 2 GW / 20 GWh pumped hydro project in the pit of an old gold mine in southeast Queensland has been declared a ‘Coordinated Project’ by the state’s Coordinator-General, a mechanism intended to fast track the plan.
