Limestone Coast North Energy Park
250MW / 500MWh Battery Energy Storage Park in South Australia
The Limestone Coast North Energy Park is the first of two new grid-scale co-located battery projects, being developed as part of the Limestone Coast Energy Park, located in regional South East Australia. These projects will significantly boost energy storage capacity, enhancing the state’s energy stability and supporting its transition to net-zero emissions.
Strategically located near the 275kV South East Substation, the batteries will store excess renewable energy and discharge it during peak demand, stabilizing the grid and lowering energy costs. The parks will collectively store up to 60% of South Australia’s residential solar output, preventing an average of 80,000 tonnes of carbon dioxide emissions annually.
Key benefits
- Limestone Coast North will enable the reduction of average wholesale electricity prices in the South Australian market by approximately $1/MWH from 2030 to 2050
- Limestone Coast North will make the grid greener by enabling a reduction in thermal energy to approximately 1 TWh between 2035 and 2060 NEM wide, leading to an estimated reduction in emissions of approximately 0.8 Mega TCO2e over time same time frame.
- For every 1 unit of generation provided by Limestone Coast North, 0.25 units of thermal generation is avoided in the system.

Location
The location of the energy park site is adjacent to the South East Electrical Substation between Peweena Road and Mingbool Road, 10kms outside of Mount Gambier. This site is perfectly situated to connect into established transmission infrastructure with virtually no impact on the local landscape, communities, and ecology.
The battery will be made up of single-story modular units similar in size to a shipping container. In total the facility will cover approximately 6 hectares of land. The footprint of the energy park will not impact on any other buildings or roads and will not be visible beyond the immediate vicinity of the site.
Timeline
The Limestone Coast Energy Park received Development Approval in August 2024. Limestone Coast North will commence construction in early 2025.
Community and stakeholder consultation and engagement
Pacific Green is dedicated to creating a cleaner environment for our communities. We do this by delivering innovative energy storage solutions that enable Australia’s net-zero transition. Our presence in regions extends beyond the provision of clean energy solutions. We partner with communities where we deliver projects and support initiatives to develop wider social value creation beyond our core business.
Our relationships within communities commence from the early stages of a project through to construction and operations. From the outset we establish open, transparent and collaborative two-way conversations that ensure we are on the ground early to share our project plans, respond to questions and hear ideas the community might have to shape project design. Every community is different, and we value the time people take to engage with us as it helps us shape our projects in a way that suits the differing environments we operate in.
Through our Limestone Coast community engagement session in November 2023, we were provided with an opportunity to share our Energy Park proposal with a cross section of the community. At this session we learned about what mattered to people and answered many questions as we gathered thoughts and feedback. We look forward to hosting more sessions in the future to continue these important conversations.
Local benefits and employment opportunities
Pacific Green is committed to sustainably contributing to local employment and training while ensuring high labour standards. During construction of our projects, employment opportunities naturally peak and at these times our approach is to maximise local direct employment and training opportunities.
We prioritise hiring from within the local community to support regional economic development and growth. Our future initiatives will look to supporting local apprenticeships and education initiatives to support career progression in the renewable energy sector.
Pacific Green held a Supplier Information Session in December 2024 to engage local businesses and service providers to support the first stage of the energy park development, Limestone Coast North. The Balance of Plant scope for the Limestone Coast Energy Park includes the installation of the battery and inverter systems as well as the supply, construction, testing and commissioning of all other plant and equipment required to support the facility.
