Indicative Capacity

up to 800 MWh

Shire of Kojonup

Location

Kojonup, Western Australia

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 up to 800 megawatt-hours (MWh) (e.g. 100 MW 8 hour system) and an indicative permanent footprint of approximately 4 hectares, though the final footprint may vary depending on the environmental considerations, grid requirements, BESS supplier and feedback from stakeholders.

BESS are a 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.

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 Location

Project Updates

We are in the early stages of development, including commencing early technical studies that will help to inform the siting and design of the Project. Once we’ve gathered more information about the proposed Project, we’ll share an update with key stakeholders, including nearby landholders and the broader community, to keep everyone informed of our progress.

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.

In late October, we will host community drop-in sessions to share updates on the Project, discuss what we’ve learned about the site so far, explain the studies we’ll be undertaking, and hear community input on the parts of the Project that can be shaped together.

We will engage with the Shire, landowners, neighbours, First Nations peoples and surrounding communities as early as possible, keeping people informed and involved.

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

Feedback is an essential part of project development. There will be opportunities for community feedback to help shape the Project. In late October, we’ll host community drop-in sessions to discuss what we’ve learned about the site so far, explain the studies we’ll be undertaking, and hear community input on the parts of the Project that can be influenced.

Feedback will help us understand the local context, inform the Project’s design and construction, guide how we communicate, and help identify meaningful ways to share benefits with the community.

Your feedback and questions are always welcome.

Join us at community drop-ins!

This October, we’ll be hosting community drop-in sessions to share updates about the Project and hear your feedback to help shape its development.

Announcements will be posted on our website, and details will also be shared through our Project Newsletters.

We encourage anyone interested in the Project to sign up to our Project e-newsletters to make sure they stay up to date with the project, including opportunities to provide formal feedback during consultation.

Benefits

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

We’ll also look to develop formal ways to share the Project’s benefits with the community. The approach will be shaped by feedback from the community and a clear understanding of local priorities, project constraints, and potential impacts.
