## Project summary

Stanwell Battery, also referred to as the Stanwell big battery, is adjacent to Stanwell Power Station near Rockhampton in Central Queensland. The 10 July 2025 article describes a planned 324-unit battery energy storage system rated at 300 MW with four-hour duration (1,200 MWh). It reports that the first Tesla Megapack 2XL consignment had arrived and that Yurika was installing the units. At the time of that article, commissioning was scheduled to commence in November 2025, with grid electricity supply scheduled to start in May 2027; those milestones are not verified by the supplied source.

## Evidence limits and unknowns

- The 10 July 2025 article does not verify whether commissioning scheduled for November 2025 commenced or whether the planned grid-supply milestone has since been reached.
- The supplied source does not state procurement status, whether supplier packages are open, project budget, or purchasing timeline.

Current purchasing availability: unknown.
Source-dated plans do not establish current progress or available supplier packages.
