The Limestone Coast Energy Park is a significant new grid-scale battery project to be developed in regional South Australia.

It will deliver a major increase in energy storage capacity in the region, strengthening the state’s energy stability and supporting its net-zero transition.

Once operational, the 1.5GWh battery will charge excess renewable energy from the grid and discharge it at periods of peak demand – helping to stabilise the grid and energy costs for South Australian customers.

The energy park will have the capacity to store almost 60% of SA’s residential solar output for up to a 4 hour period, enabling an average of 80,000 tonnes of carbon dioxide to be avoided each year by discharging renewable power to the grid during evening peak times and overnight.

About The Park

The proposed Energy Park is adjacent to the South East Electrical Substation 10kms outside of Mount Gambier and is perfectly situated to connect into established transmission infrastructure with virtually no impact on the local landscape, communities, and ecology.

As the South East Electrical Substation is on the interconnector between South Australia and Victoria, the Limestone Coast energy park can also charge excess renewable energy from Victoria or discharge excess renewable energy from South Australia to Victoria. 

Safety and Sustainability

Pacific Green is committed to zero harm to the community and its employees. In addition to first-class technical engineering that’s designed to meet IEC and Australian standards, all Pacific Green energy storage projects undergo rigorous safety and security testing to minimise safety risks.

Each container is built with multiple fire safety protection systems, including real-time temperature monitoring at the battery cell level, PACK automatic fire extinguishing system.

The battery has an initial lifespan of 20 years but new generation cell technology will provide longer lifespan, so that the site can be renewed and enhanced continually, making the project sustainable into the future.

The Limestone Coast Battery is currently going through its regulatory approval process and is scheduled to be constructed in 2024.
