Energy Vault Holdings, a global leader in grid-scale energy storage solutions, and its Australian development partner Bridge Energy Pty Ltd have announced that the Ebor Battery Energy Storage System (BESS) has secured a 14-year Long-Term Energy Service Agreement (LTESA) under the New South Wales (NSW) Electricity Infrastructure Roadmap.
The 100 MW / 870 MWh Ebor BESS, located in Ebor within the New England region of NSW, will provide up to eight hours of dispatchable energy storage capacity, playing a critical role in supporting grid reliability as aging coal-fired power plants retire. The project will charge during periods of surplus renewable generation and discharge during peak demand, helping NSW progress toward a more resilient and decarbonised electricity system.
Energy Vault holds an exclusive option to acquire and construct the A$310 million project, having supported Bridge Energy through its early-stage development. Subject to regulatory and contractual approvals, Energy Vault plans to exercise this option and will ultimately build, own, and operate the project under its Asset Vault “Own & Operate” platform.
The Ebor BESS will deploy Energy Vault’s proprietary B-VAULT™ battery system architecture, designed for long-duration, high-performance cycling applications, alongside the company’s Vault-OS™ Energy Management System, which will optimise system performance and asset value.
The project is currently in the development phase, with local community consultation underway. Construction is expected to create up to 60 direct jobs, with commercial operations targeted for 2028. In addition, the project includes long-term community benefit contributions through the New England Future Fund, administered by the Armidale Regional Council.
The Ebor BESS award builds on Energy Vault’s expanding Australian footprint, following its 2025 acquisition of the 125 MW / 1,000 MWh Stoney Creek BESS, which also holds an LTESA. Together, these projects reinforce Energy Vault’s growing role in Australia’s long-duration energy storage market and its broader global Asset Vault strategy.
