As part of the Australian Energy Market Operator (AEMO) Services’ NSW Long Duration Storage tender, Stoney Creek BESS contributes to strengthening grid reliability, system resilience, and network stability. The selection of Stoney Creek BESS as an LTESA project underscores the strategic importance of the project in advancing Australia’s energy transition. 
 
The Stoney Creek BESS is one of the largest battery storage projects in New South Wales and will play a pivotal role in the State’s energy transition, providing large-scale, dispatchable storage capacity to support grid reliability and renewable integration. By balancing energy generation and enhancing system resilience, Stoney Creek BESS will contribute to wholesale price stability, reinforcing the energy market benefits outlined in AEMO Services’ tender outcomes. 
 
Now that the LTESA has been formally awarded, we can confidently move forward with the detailed design and relevant pre-construction activities, noting that the project site is fully secured, we are already engaging with the community and moving through final regulatory approvals. 

Enervest Managing Director, Ross Warby, emphasised the project’s significance:

“Stoney Creek BESS being awarded the LTESA is a pivotal step in delivering critical infrastructure that drives Australia’s energy transition, economic growth, and long-term system reliability. The Stoney Creek BESS is a key step in scaling Australia’s storage capacity to meet rising demand for flexible, low-carbon energy solutions. We recognise AEMO Services’ leadership in advancing projects that strengthen Australia’s energy future as well as consortium partner Energy Vault’s expertise in battery technology, software and system design.” 

Enervest acknowledges the Traditional Owners of the land on which this project will be developed and remains committed to working closely with Indigenous communities, local councils, and community groups to maximise long-term benefits of Stoney Creek BESS for the region.
