A Land of Opportunity: SA’s Unprecedented Renewables Push
The South Australian government has fired the starting gun on a massive renewable energy expansion, inviting investors to develop over 11,000 square kilometres of prime land for new large-scale wind and solar projects. The move, announced on April 9, 2026, is the first major initiative under the state’s pioneering Hydrogen and Renewable Energy Act 2023 and signals a clear intention to cement South Australia as a national leader in the green energy transition.
Investors are being invited to bid for feasibility licences across two newly designated zones: the 5,200km² Gawler Ranges East on the Upper Eyre Peninsula and the 6,500km² Whyalla West in the Upper Spencer Gulf region. Together, this territory is more than double the size of Kangaroo Island and has been specifically chosen for its exceptional combination of co-located wind and solar resources, making it ideal for hybrid generation projects.
According to government estimates, the projects developed in these regions could collectively generate enough clean electricity to power more than 500,000 homes, representing a significant boost to the National Electricity Market (NEM).
Strategic Growth Under New Legislation
This landmark land release is designed to provide a structured and sustainable pathway for the next wave of green energy investment in the state. By creating a clear framework under the new Act, the government aims to avoid the conflicts over land use seen elsewhere and streamline the development process for major projects. The tender process is now open, with a 13-week window for applicants to submit their proposals, closing on June 28, 2026.
This large-scale generation push is a critical part of the state’s strategy to decarbonise its economy and provide stable, affordable power. As households grapple with rising costs, ensuring a robust supply of low-cost renewable energy is more important than ever.

What Developers Need to Demonstrate
The government has made it clear that it is not simply looking for the biggest proposals, but the best. Applicants will be evaluated on a range of criteria beyond just generation capacity. These include their industry experience, project delivery timelines, and comprehensive environmental management plans.
Crucially, proposals must also detail the benefits they will bring to the state and to traditional landowners. During the tender period, developers are expected to engage directly with native title holders and local stakeholders to ensure project plans are inclusive and build community support from the ground up.
The flexibility in the tender process allows for a range of technologies, not just wind and solar, opening the door for large-scale battery storage and green hydrogen production facilities.

This strategic release of land is a clear signal to global energy investors. By proactively identifying and de-risking suitable locations for development, South Australia is positioning itself not just as a participant, but as a leader in Australia’s renewable energy future.
