Project Overview

Long-Duration Power for NSW

The Stoney Creek Battery Energy Storage System (BESS) is a 1.0 gigawatt-hour (GWh), 8-hour duration facility in Narrabri, New South Wales, one of Australia's largest long-duration battery projects.

Developed by Energy Vault in partnership with Enervest and featuring a 125 megavolt-ampere (MVA) connection, the project was awarded a 14-year Long-Term Energy Service Agreement (LTESA) by the Australian Energy Market Operator (AEMO) Services. It 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.

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 AEMO 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.

Our Long-Term Community, Workforce and First Nations Commitments

Delivering Long-Term Community Value

Energy Vault will deliver two cornerstone community initiatives over a 14-year period. Community Development Fund — $420,000. Indigenous Services Support — $1,050,000. These initiatives will be delivered in consultation with local councils, Traditional Owners, and community stakeholders, supporting programs focused on education, wellbeing, inclusion, and community resilience.

Education and Skills Development

Once operational, the project will partner with Narrabri TAFE to support training programs for up to 10 participants. Potential courses include the Diploma of Project Management, Certificate IV in Work Health and Safety, and diplomas in Conservation and Ecosystem Management, Horticulture Management, and Logistics. These programs are designed to strengthen local employment readiness and build long-term capability within the energy and infrastructure sectors.

Supporting Regional Industry Through Local Procurement

Energy Vault’s procurement strategy prioritizes local and regional suppliers to maximize economic participation and regional growth. Key commitments include approximately $100 million in local goods and services during development and construction, approximately $26 million in local operational and maintenance expenditure, and 100% Australian-sourced steel for project construction activities. This approach supports job creation, strengthens domestic supply chains, and delivers sustained regional economic benefits.

Workforce Development and Inclusion

The project includes measurable workforce inclusion targets for the construction phase: 20% of the workforce to be learning workers, 15% participation from underrepresented groups, and 20% of trade roles filled by apprentices. These commitments will be supported through training, mentoring, and career development pathways for local workers and students.

First Nations Participation and Engagement

Energy Vault is committed to meaningful and measurable Aboriginal and Torres Strait Islander participation, including 1.5% of total project value directed to First Nations businesses, 5% First Nations workforce participation, and $320,000 allocated to targeted training and employment initiatives. These commitments will be delivered in collaboration with local First Nations stakeholders, including engagement with the Narrabri Aboriginal Land Council and the Gomeroi community.

Project Partnership and Community Commitment

The Stoney Creek BESS is being developed with Enervest as development partner, with Energy Vault responsible for delivering long-term project outcomes and community commitments. Through this framework, Energy Vault aims to establish best-practice standards for community engagement in energy infrastructure development and ensure that regional communities are active participants in the project’s long-term success.

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.
