Australian-owned and operated Enervest Group is partnering with Energy Vault Holdings on a 1-gigawatt hour battery energy storage system (BESS) project being deployed in South Wales, Australia, according to an Oct. 21 news release.

Energy Vault will serve as the engineering, procurement, construction and commissioning partner and system integrator for the project. The companies are now finalizing development and grid application approvals to bring the project to a full final investment decision, as part of the agreement, Energy Vault said in the release.

The Stoney Creek BESS project aims to bolster stability of the New South Wales power grid. The BESS will be built with Energy Vault’s proprietary X-Vault integration platform.

“Energy Vault’s leading integrated hardware and software solution coupled with their deep technology and system design expertise makes Energy Vault an ideal partner for the Stony Creek BESS,” said Enervest CEO Ross Warby. “We value strong partnerships such as the one we have with Energy Vault and consider such collaborations as cornerstone to accelerated, quality project development.”

The partnership takes shape as Energy Vault continues to expand its footprint in Australia. The company recently announced 400 megawatt hours of BESS projects in New South Wales that it plans to deliver in 2025, the release states.

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