Stoney Creek is designed to provide 8-hours of dispatchable storage and is supported by a 14-year Long-Term Energy Service Agreement (LTESA) awarded through AEMO Services under the New South Wales Electricity Infrastructure Roadmap, expected to generate annual revenue of approximately US$25-30 million.

Energy Vault chief development and operations officer Akshay Ladwa said the completed land acquisition represented “another important execution milestone” as the project advances toward construction, while chief revenue officer Marco Terruzzin described Australia as “a strategic growth market” for the company.

Energy Vault plans to use its VaultOS energy management platform to optimise the asset’s performance, market participation and lifecycle operations once operational.

From co-development to full ownership under Energy Vault’s Own & Operate strategy

Stoney Creek’s path to full ownership has moved through several stages since Energy Vault first partnered with Australian developer Enervest Group on the project.
