Stoney Creek represents first acquisition in Australia as part of Energy Vault's global "Own & Operate" portfolio and reinforces long-term commitment to Australia's energy transition
125 MW/1,000 MWh Stoney Creek BESS set to support grid reliability and flexibility while advancing the energy transition in New South Wales, supported by a 14-year offtake agreement
Stoney Creek is Energy Vault's third and largest Energy Storage Asset in the portfolio, following the successful completion of the Cross Trails BESS in Texas and Calistoga Resiliency Center in California, and is expected to deliver ~$30 million in combined annual, recurring EBITDA for the next 15+ years
Energy Vault Holdings, Inc. (NYSE:NRGV) ("Energy Vault"), a global leader in grid-scale energy storage solutions, today announced it has received Foreign Investment Review Board (FIRB) approval and completed the full acquisition of the Stoney Creek Battery Energy Storage System (BESS) project in Northern New South Wales. The 125 MW/1,000 MWh project now formally enters Energy Vault's international "Own & Operate" portfolio, advancing the company's long-term asset management strategy in the Australian market.
Energy Vault has formalized its investment position in the Stoney Creek BESS following receipt of Foreign Investment Review Board (FIRB) approval, enabling full acquisition and control of the project's development and operations. The project was initially announced for acquisition from Enervest Group in March 2025.
This strategic acquisition underscores Energy Vault's commitment to accelerating Australia's transition to a more resilient, low-carbon energy grid. The Stoney Creek BESS represents a flagship deployment within the company's Asset Vault portfolio, leveraging Energy Vault's vertically integrated approach to energy storage development. With full control of the project's lifecycle—from design through long-term operation—Energy Vault is positioned to optimize both performance and profitability while delivering essential grid services.
The project's award of a 14-year LTESA contract provides a strong foundation of contracted revenue, enabling long-term value creation for stakeholders and reinforcing investor confidence. Coupled with Energy Vault's proprietary VaultOS™ platform and advanced B-VAULT™ storage technology, the Stoney Creek BESS will offer critical dispatchable capacity to support peak demand, enhance grid stability, and enable deeper integration of renewable energy sources across New South Wales.
The 125 MW/1,000 MWh BESS was awarded a 14-year Long-Term Energy Service Agreement (LTESA) under Roadmap Tender Round 5 for Long Duration Storage, administered by AEMO Services as the Consumer Trustee under the New South Wales Electricity Infrastructure Roadmap. The LTESA provides up to 14 years of predictable, contracted revenue, helping to de-risk the project and accelerate investment in critical storage infrastructure.
The Stoney Creek BESS has been designed to deliver eight hours of dispatchable energy, and once operational, will support grid reliability and flexibility in a strategic location within NSW's transitioning energy landscape. Energy Vault is developing and integrating the project, utilizing its VaultOS™ energy management platform and B-VAULT™ system to optimize performance, market participation, and long-term asset management.
