How this was derived
This is a nearby Darling Downs-region BESS, but it is not APA's Darling Downs BESS and should not be used as the APA site's capex.

Notes
No plant-specific APA announcement or project page for a Darling Downs BESS at APA was found in the provided search results. The nearby Wandoan South BESS (Vena Energy, 100 MW / 150 MWh) is in the Darling Downs region and had a reported construction budget of $120 million, but it is a different asset and should not be used as capex for this APA site. Because no verified APA-specific greenfield capex or operating assumptions were located, financial fields remain unfilled pending further review. Battery storage has no fuel cost or heat rate; emissions intensity is operationally zero.
