Energy Vault will act as the turn-key engineering, procurement, construction and commissioning partner for the Stoney Creek project.

They will also provide long-term services, software and maintenance support throughout the project’s lifespan.

The BESS will be constructed using Energy Vault’s X-Vault integration platform and B-VAULT product, certified by UL9540 and AS3000, managed by the Vault-OS Energy Management System.

The system’s architecture offers customers flexibility with battery and inverter suppliers.

Its AC-coupled and DC-coupled configurations provide the versatility needed for any project.

The latest announcement marks an expansion of Energy Vault’s presence in the Australian market, following 400 megawatt-hours of projects in NSW which are scheduled for delivery in 2025.

Energy Vault Board chairman and CEO Robert Piconi said: “We continue to expand and convert on our growing, multi-GWh funnel of energy storage projects in Australia and look forward to building the partnership with Ross and his team at Enervest.

“With Enervest, we share a focus on large-scale and financially attractive projects to enhance grid resiliency, and the Stoney Creek project is another example of executing the growth plans that we have outlined for 2025 and beyond.”

In May 2024, Energy Vault secured contracts from ACEN Australia to install two large-scale BESS facilities.
