GE Renewable Energy and BE Power have signed an agreement to co-develop the 400 MW Big-T Cressbrook pumped hydro storage project in Toowoomba, Australia. Under the agreement, GE Renewable Energy’s Hydro Solutions business will work alongside BE Power and their partners to optimize and finalize the design of the plant and help the project secure financing and reach commercial operations. When generating, the project will provide power equivalent to the demand of roughly 200,000 typical Queensland households; when pumping, it will provide long-duration, high capacity storage to absorb excess wind and solar output. At all times, it will provide valuable system strength and inertia to the grid, safeguarding security and reliability.
As Queensland pushes towards its target of 50% renewables by 2030, projects such as the Big T will be vital enablers, ensuring that supply continues to meet demand, despite the variable nature of other renewable energy resources. Given the scale of the transformation that is under way, pumped hydro projects such as the Big T represent by far the most cost-effective and long-lasting solution for the high capacity, long duration storage that is needed
