Windlab and Squadron Energy have referred a 500MW solar-plus-storage site for EPBC Act approval in Australia, marking a significant development in the country's renewable energy sector. This project, known as Bungaban Solar, is part of a larger wind and solar hub anchored by a substantial Rio Tinto offtake deal. The hub includes the Bungaban Wind Farm, a 1.4GW, AU$3.9 billion development, and is designed to generate around 80% of its energy over 25 years for Rio Tinto's Queensland aluminium and manufacturing operations, with the remaining 20% intended for Australia's National Electricity Market (NEM).
The Bungaban Solar project is a joint venture between Federation Asset Management, which wholly owns renewable energy developer Windlab, and Squadron Energy, established in April 2026. This marks a shift in the development's leadership, as Windlab had previously led the project alone. Squadron Energy, described as Australia's largest renewable energy developer, brings expertise in battery storage and hybrid projects, reflecting its recent AU$2.7 billion refinancing commitment to expand into these areas.
The EPBC Act submission includes a transmission line connecting the solar and battery infrastructure to Powerlink's proposed Warranna substation, which is part of the separate Bungaban Wind Farm Connection Project. Construction is proposed to start in July 2028, with a project life extending to 2068. The Western Downs Regional Council approved the development application in June 2026.
The project has undergone extensive consultation since 2022, with dedicated public consultation on the solar component expanding from early 2025. This has included briefings with local councils, community information sessions, and a social impact assessment process that engaged around 170 stakeholders. The proponent's assessment concluded that the project is unlikely to have a significant impact on any listed species or ecological community, and no environmental offsets are required.
However, the project's potential impact on threatened and migratory species, including the koala, greater glider, and Belson's panic, as well as ecological communities such as Brigalow and Poplar Box Grassy Woodland, has been a key consideration. The ecological assessment found that the development footprint would affect only a small proportion of relevant habitat, with 99.99% of ground disturbance occurring within already cleared, non-remnant vegetation.
Despite these findings, the project's approval process under the EPBC Act is ongoing, and the referral is subject to public scrutiny and potential challenges. The project's scale and the involvement of major players in the renewable energy sector make it a significant development in Australia's energy transition, but the potential environmental impacts and community engagement remain critical aspects of the approval process.
In my opinion, the Bungaban Solar project represents a significant step forward in Australia's renewable energy landscape. It showcases the country's commitment to diversifying its energy sources and reducing its reliance on fossil fuels. However, it also highlights the need for rigorous environmental assessments and community engagement to ensure that such projects are sustainable and socially responsible. The project's success will depend on its ability to balance economic development with environmental protection and community acceptance.
One thing that immediately stands out is the collaboration between Windlab and Squadron Energy, which demonstrates the potential for joint ventures to accelerate the development of renewable energy projects. This partnership model could become a key strategy for the industry, especially as the demand for clean energy solutions continues to grow. The project's scale and the involvement of major players in the renewable energy sector make it a significant development in Australia's energy transition, but the potential environmental impacts and community engagement remain critical aspects of the approval process.
What many people don't realize is that the Bungaban Solar project is just one piece of a larger puzzle in Australia's energy transition. The country is facing a growing demand for clean energy, and projects like this are essential to meet that demand while also addressing environmental concerns. The project's success will depend on its ability to balance economic development with environmental protection and community acceptance.
If you take a step back and think about it, the Bungaban Solar project is a testament to the potential of renewable energy to transform the Australian economy. It showcases the country's commitment to a sustainable future and the role that solar and storage technologies can play in achieving that goal. However, it also highlights the need for careful planning and community engagement to ensure that such projects are successful and widely accepted.
This raises a deeper question: How can Australia balance the rapid development of renewable energy projects with the need for environmental protection and community acceptance? The answer lies in a comprehensive approach that integrates environmental assessments, community engagement, and economic development strategies. The Bungaban Solar project is a step in the right direction, but it is just one piece of the puzzle.
