Tummaville Solar Farm
Delivering renewable energy for Queensland's future
Project overview
The Tummaville Solar Farm project is a proposed renewable energy development near Tummaville in Queensland's Darling Downs region, within the Toowoomba Regional Council local government area. The project is being co-developed by ACEnergy and InnoGreen Energy. The project is proposed to generate up to 600 MWp of solar energy alongside a 500 MWac (4,000 MWh) battery energy storage system (BESS). Together, these components will provide reliable, affordable and clean power for homes and businesses across Queensland. The project will also create local jobs and support long-term investment in the region.
Our team is working with leading experts to create a carefully planned project that balances technical excellence, environmental care, and community outcomes.
Acknowledgement of Country
We acknowledge the Traditional Custodians of the lands and waterways on which the Tummaville Solar Farm is proposed. We pay our respects to their Elders past and present and acknowledge their enduring connection to Country.
Project location
The Tummaville Solar Farm project is located approximately 76 kilometres south-west of Toowoomba in Queensland's Darling Downs region - an area with a long history of agriculture and local industry that is also expected to play an important role in Queensland's renewable energy future.
For generations, this land has been used for cattle grazing. The Project presents an opportunity to add a complementary land use that can coexist with farming, while supporting regional economic diversification and long-term regional investment.
Why Tummaville?
The Tummaville area has several characteristics that make it well suited to renewable energy development, including:
Strong solar resources and relatively flat terrain, which are well suited to large-scale solar generation.
Proximity to the existing Powerlink Tummaville Substation, allowing the Project to connect into established electricity infrastructure and reducing the need for significant new transmission infrastructure.
Access to regional centres and major transport routes, which can help support local jobs, suppliers and service providers during both construction and operations.
The Darling Downs region has a long history of agriculture and local industry, and is increasingly contributing to Queensland's renewable energy future. Developing the project here helps ensure the region continue to grow and diversify.
