Energy Vault Holdings, Inc., a leader in sustainable, grid-scale energy storage solutions, has announced that the Stoney Creek Battery Energy Storage System (BESS) has been awarded a 14 year Long-Term Energy Service Agreement (LTESA) by the Australian Energy Market Operator (AEMO) Services under the New South Wales (NSW) Roadmap Tender Round 5 for Long Duration Storage.
In partnership with Enervest, a leading Australian project developer, the previously announced Stoney Creek BESS located in Narrabri, NSW is a 1.0 gigawatt-hour battery system connected with a 125MVA connection, creating one of the largest 8-hour long duration battery systems in Australia. As part of AMEO Services’ NSW Long Duration Storage tender, the Stoney Creek BESS contributes to the growing portfolio of projects enhancing system reliability and supporting the state’s energy transition goals. The selection of Stoney Creek BESS as an LTESA project underscores the strategic importance of the project in advancing Australia’s energy transition.
Along with the Calistoga Resiliency Center in Calistoga, California and the Cross Trails BESS in Snyder, Texas expected to come online the first half of this year, the Stoney Creek BESS is expected to be one of the first Australian projects in Energy Vault’s portfolio of ‘Owned & Operated’ projects, demonstrating continued successful execution of the global growth strategy outlined during the Company’s May 2024 Investor and Analyst Day.
Robert Piconi, Chairman and CEO of Energy Vault, highlighted the Stoney Creek project as a key milestone in executing their ‘Own & Operate’ growth strategy. He emphasized the importance of the Australian market in driving growth, noting Energy Vault’s expertise in designing, building, and operating energy storage systems at lower costs, ensuring long-term, profitable cash flow for shareholders.
Piconi expressed pride in partnering with Enervest on the Stoney Creek BESS, one of the first long-duration battery energy storage systems in New South Wales. He also highlighted Energy Vault’s ongoing projects in California and Texas, including a green hydrogen-powered micro-grid. Piconi emphasized the company’s commitment to supporting New South Wales’ renewable energy goals and building a resilient future grid.
Ross Warby, CEO of Enervest, highlighted that the Stoney Creek BESS’s LTESA award is crucial for Australia’s energy transition and long-term system reliability. He praised the successful partnership with Energy Vault, emphasizing their expertise in energy storage solutions and operations. Warby also acknowledged AEMO Services’ leadership in advancing projects to strengthen Australia’s energy future.
Project Highlights:
- 150 jobs created at peak construction, with four full-time operational roles post-completion.
- Site mobilization, pre-construction and procurement activities expected in the second half of 2025 following final procedural and DA approvals.
- A cornerstone project within the NSW Government’s Renewable Energy Roadmap, supporting the state’s decarbonisation goals.
- Strategic engagement with Traditional Owners, community groups, and local councils to ensure a collaborative, sustainable development approach that maximises local benefits. A major step toward expanding Australia’s energy storage capacity, reinforcing grid reliability and resilience.
Enervest and Energy Vault acknowledge 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.
