Mint is proposing to develop a Battery Energy Storage System (BESS) located 3 km north west of Kojonup next to the existing Kojonup Substation in the Great Southern region of Western Australia.

The Kojonup BESS could have an indicative capacity of up to 800MWh (e.g. 100MW x 8 hour system) and an indicative footprint of approximately 4 hectares. The final size of the Project will depend on planning and environmental considerations, grid requirements, the selected BESS model and feedback from stakeholders.

Battery Energy Storage Systems, or BESS, are safe technology that stores energy in rechargeable batteries for use when it is needed most. It acts like a large-scale version of the batteries in our phones, or laptops, but it’s designed for large-scale grid energy storage. BESS provide the ability to store energy, so that excess energy produced during periods of low demand or high output (e.g. from variable sources such as wind or solar) can be stored for use during periods when there might otherwise be a shortfall in supply.

Kojonup BESS is strategically located near the Kojonup Substation, located off Tunney Road, to enhance grid reliability in the Great Southern Region while reducing the need for additional transmission infrastructure. The site offers suitable cleared land and proximity to the Albany Highway, minimising environmental and construction impacts.

​Development of a BESS undergoes a comprehensive planning and environmental assessment process to ensure the Project’s impacts are minimised and managed during construction and operations. This process also involves engaging with the community to understand local concerns and incorporate them into the development of the Project.  

When fully charged, an 800 MWh BESS (e.g. 100 MW 8 hour system) has enough energy capacity to supply over 168,000 Western Australian homes for 8 hours.

Project Updates

Mint has now lodged a Development Application (DA) with the Shire of Kojonup for the proposed Kojonup Battery Energy Storage System (BESS) Project. The DA will be assessed under the Planning and Development Act 2005 via the Development Assessment Panel (DAP) pathway.

The Development Application is now on public notice and available at the Shire of Kojonup’s website. During the public notice period, stakeholders can provide feedback on any aspect of the proposal, including potential impacts, local considerations, or opportunities for improvement. All submissions are formally considered by the Shire and the proponent as part of the assessment process.

We encourage anyone interested to take the opportunity to review the application and provide feedback.

Community members can review the application and make submissions to the Shire website. Submissions must be received by 2:00pm, 27 July 2026.

We encourage anyone interested in the Project to sign up to our Project Newsletter to make sure they stay up to date with the project, including opportunities to provide formal feedback during the public notice period. 

Community & Benefits

We strive to be active and caring neighbours, dedicated stewards of the environment, and create meaningful, lasting benefits for the broader community.

We know that for our projects to be successful, we must work closely with our stakeholders, including landholders, project neighbours, First Nations peoples and the broader community.

Consultation

In October 2025, the Project held three community drop-ins at the Kojonup RSL Hall. These drop-in sessions were advertised and promoted across a broad range of channels.

In November, the Project undertook another round of neighbour outreach, including door knocking adjoining properties and offering one-on-one meetings. This was followed by the launch of a community survey to gather insights, which remained open until early 2026.

Feedback gathered through these activities informed the Development Application (DA), helping identify key environmental, social and economic considerations.

Following the DA being placed on public notice in late June, a community pop-up was held on Saturday 4 July outside the Kojonup IGA, providing an opportunity for community members to ask questions about the Project and the DA.

We appreciate everyone who took the time to attend and speak with the project team. Feedback received during these sessions indicated general support for the Project, particularly in relation to improving energy security and the role of batteries in providing a reliable back-up source of electricity. Community members also raised concerns relating to potential fire risk and noise. These matters will continue to be considered as part of the assessment and design process.

For information about BESS systems, including how they operate and the safety measures in place, please refer to the BESS FAQs.

Community feedback

We know that locals have important insights and knowledge about the land they live on, and we value the time people have taken to share their views.

Community feedback will help us better understand the local area, inform the design and construction of the Project, and consider how benefits could be shared with the local community.

The community survey is now closed. We’d like to thank everyone who participated.

We are currently reviewing the feedback received and are working to prepare an update on what we heard. This will be shared in the coming weeks.

Benefits‍ ‍

We know that our Project will bring inherent economic and social benefits to the Kojonup community, through a boost to the local economy, local businesses and jobs during construction and operations.

In addition to creating opportunities for local workers, the Project will bring benefits to other industries, including accommodation providers, cafés, and restaurants. Mint is committed to employing local people, sourcing locally wherever possible, and engaging local service providers.

Our commitment to sharing benefits

We will also develop other ways to share benefits of the Project, informed by engagement with stakeholders throughout the development phases of the Project.

As an initial benefit sharing commitment, we are committed to contributing a minimum of $150 per megawatt per year in community benefits from the commencement of operations.

This is intended as a starting point only and represents the minimum commitment. The final approach to benefits will be shaped by feedback from the community and a clear understanding of local priorities, project constraints, and potential impacts.

Local businesses and service providers

Are you a local business or service provider looking to be part of an exciting opportunity?

We’re building a Goods and Services Register for our Project and we’re inviting local suppliers to register their interest, via this form.

Environment & Planning

The Kojonup BESS will go through a rigorous planning and environmental assessment process to ensure impacts are minimised and managed during construction and operations.

Mint has now lodged a Development Application with the Shire of Kojonup for the proposed Kojonup Battery Energy Storage System (BESS) Project. The application is currently in its public notice period, providing an opportunity for community members to review the proposal and share feedback—whether supportive, neutral or opposed.

Community members can review the application and make a submission to the Shire in the following ways:

Submissions must be received by 2:00pm, 27 July 2026.

The Project will seek development approval and be assessed under the Planning and Development Act 2005.

Specialist studies will assess potential impacts and outline mitigation measures, including:

There are opportunities for public input through the Project approval process.
