The Western Downs Battery, owned and operated by Neoen Australia, is adding new capacity to bolster Queensland’s grid reliability and energy supply security.
Stage 3 will deliver a 305 MW / 1,220 MWh four‑hour system comprising 312 Tesla Megapacks 2XL units, bringing the total number of units to 592. This expansion significantly increases the state's ability to store and dispatch renewable energy at scale and further supports Queensland's transition in energy generation.
Stage 2 was delivered ahead of schedule by UGL thanks to disciplined planning, collaborative delivery and a commitment to high standards. That success allowed the UGL construction team to carry momentum directly into Stage 3, applying lessons learnt and re‑establishing the site quickly after the end-of-year period. This strong start to Stage 3 reflects the quality and consistency of UGL’s work across the Battery’s multiple stages.
Progress on Stage 3 is already visible. Early procurement began months ago, civil designs have been issued for construction, and the site has officially broken ground for the substation. The focus now is on bulk earthworks, trenching and concrete works, and preparing the site for Megapack installation.
UGL Project Manager Jack Connors said the team’s approach is grounded in quality and reliability.
“Our team is committed to maintaining momentum and delivering each phase with the same focus on safety, precision and performance. It’s exciting to see the project already contributing to Queensland’s grid from its previous stages while we focus on constructing a third stage.”
With each stage, the Western Downs Battery becomes a more critical piece of Queensland’s clean energy future. By storing renewable energy when it’s abundant, and releasing it when demand peaks, the battery strengthens the electricity grid and reduces reliance on fossil fuels.
UGL is proud to help Neoen deliver one of Queensland’s largest battery systems, supporting the infrastructure that will power the state for decades to come.
