Queensland's Tumuruu Project: 400 MW Solar + 2 GWh Battery Approved ⚡
The news
On 11 May 2026, the Department of Climate Change, Energy, the Environment and Water gave federal approval to the Tumuruu project — a 400 MW solar farm paired with a 2,000 MWh battery energy storage system on a 673-hectare site north of Blackbutt, in Queensland's South Burnett region. The project is being developed by Australian Solar Enterprises (ASE), with a final investment decision targeted for later this year and operations expected to start in 2028.
2,000 MWh — that's 2 GWh — puts Tumuruu among the largest battery storage projects in Australia by capacity. For context, that single project can store as much electricity as around 100,000 typical home batteries combined.
The site will use grid-forming inverters, which means the battery system can help stabilise grid frequency and voltage on its own — a capability that conventional inverters don't have, and one that becomes increasingly important as more renewable generation enters the network.
For South-East Queensland households and businesses, the practical implications are downstream rather than immediate:
- More renewable generation on the grid through the late 2020s
- More large-scale storage smoothing out the midday solar peak and the evening demand peak
- Continued pressure on coal generation economics, which feeds into wholesale electricity prices
- A clearer signal that battery storage — at every scale, from household to grid — is core infrastructure rather than a niche add-on
