In a significant policy move to accelerate its clean energy ambitions, the South Australian government has opened a global call for investors to develop large-scale renewable energy projects across more than 11,000 square kilometres of newly released land. The announcement, made this week, marks one of the largest land releases for green energy in the state’s history and is a critical step towards its goal of 100% net renewable energy by 2027.
Applications for renewable energy feasibility licenses are now officially open for two major parcels of land: the Whyalla West release area, spanning approximately 6,500 sq km in the Upper Spencer Gulf region, and the Gawler Ranges East area, covering around 5,200 sq km on the Upper Eyre Peninsula.
According to South Australia’s Department of Energy and Mining (DEM), these specific areas have been selected for their high-quality, co-incident wind and solar resources, making them prime locations for hybrid renewable projects. Government estimates suggest that projects developed in these zones could collectively generate enough clean electricity to power more than half a million homes.
A Global Invitation for Green Investment
This major land release is being managed under the state’s pioneering Hydrogen and Renewable Energy Act, which is designed to provide a clear regulatory framework for large-scale projects. The government is inviting proposals from investors across the globe, signalling a major push for international capital and expertise to build out the state’s energy infrastructure.
The tender process is notably technology-agnostic, allowing applicants to propose a mix of large-scale solar, wind, and energy storage solutions. This flexibility encourages investors to design projects that optimise the use of the land and its natural resources. In a statement, the DEM outlined the key criteria for successful applications.
“Tenders must address the prescribed criteria in their application, including how they plan to deliver the content within a timeframe, their experience, environmental management credentials, and how the project will benefit the state and the traditional custodians of the land.”
The deadline for tender submissions is June 28, 2026. The government has stated this extended period is designed to give applicants sufficient time to prepare comprehensive bids and, crucially, to engage with native title holders on agreements.
Cementing a National Leadership Role
South Australia is already a recognised leader in Australia’s energy transition. The state currently averages 75% net variable renewable energy annually and frequently achieves periods of 100% instantaneous generation from its existing fleet of large-scale wind and solar farms, complemented by a high uptake of rooftop PV.
Having brought its 100% net renewables target forward from 2030 to 2027, this land release is a clear policy action intended to bridge the remaining gap. By de-risking the initial stages of project development and identifying suitable land, the government aims to streamline the process for developers and ensure its ambitious energy goals are met.
The scale of the release in the Upper Spencer Gulf and Eyre Peninsula—regions already earmarked for green hydrogen and industrial decarbonisation projects—suggests a broader strategy of creating interconnected clean energy hubs. These new renewable energy zones will not only supply the state’s grid but also potentially power a future green manufacturing and export industry.
For the national energy market, this move by South Australia serves as a powerful blueprint for how state governments can proactively facilitate the immense level of investment required to meet Australia’s 2030 and 2050 emissions reduction targets. As global investors look for stable and supportive policy environments, this 11,000 sq km invitation is a clear signal that South Australia is open for business.
