Stoney Creek Battery Energy Storage System
Energy Vault's first fully owned and operated battery energy storage system (BESS) in the Australian market providing 8-hours of power to the New South Wales region.
Project Overview
The Stoney Creek Battery Energy Storage System (BESS) is a 1.0 gigawatt-hour (GWh) facility located in Narrabri, New South Wales, developed by Energy Vault in partnership with Enervest. Featuring a 125 megavolt-ampere (MVA) connection, this 8-hour duration system is one of Australia's largest long-duration battery projects. Awarded a 14-year Long-Term Energy Service Agreement (LTESA) by the Australian Energy Market Operator (AEMO) Services, the project will provide critical grid stability, balancing renewable energy generation and enhancing system resilience in line with New South Wales' decarbonization goals.
Currently in the development phase, the Stoney Creek BESS is expected to begin construction in 2025, creating up to 150 jobs at peak construction and four full-time operational roles once completed. This project is a key part of Energy Vault’s ‘Own & Operate’ growth strategy, reinforcing its commitment to delivering sustainable, long-duration energy storage solutions that support Australia’s energy transition.

Project Delivery Highlights

Community Boosting
Stoney Creek will create 150 jobs at peak construction and four full-time operational roles while actively engaging Traditional Owners, community groups, and local councils to ensure a collaborative, sustainable development that strengthens the local economy and enhances grid reliability.

Market Leading Project
In partnership with Enervest, the 1.0 GWh Stoney Creek BESS leverages the B-VAULT architecture and is one of Australia's largest 8-hour battery systems, selected under AMEO Services' NSW Long Duration Storage tender. Its inclusion as an LTESA project highlights its strategic role in enhancing grid reliability and accelerating Australia’s energy transition.

Own and Operate
The Stoney Creek BESS is expected to be one of the first Australian projects in Energy Vault’s portfolio of ‘Owned & Operated’ projects, demonstrating continued successful execution of the global growth strategy

Software-Enabled Startup and Operation
The VaultOS™ Energy Management System will control, manage and optimize the BESS operations, allowing for superior energy management capabilities.

“Stoney Creek BESS being awarded the LTESA is a pivotal step in delivering critical infrastructure that drives Australia’s energy transition, economic growth, and long-term system reliability. The partnership with Energy Vault early in the project development and final bid submission last year ensured we would have a comprehensive and successful bid with a proven global leader in energy storage solutions and operations. We recognize AEMO Services’ leadership in advancing projects that strengthen Australia’s energy future as well as consortium partner Energy Vault’s expertise in battery technology, software and system design.”
