Notes
No project-specific capex announcement found in the available search results for Darling Downs Battery / BORAL. The search results returned unrelated or adjacent projects (for example Origin Energy's Darling Downs Power Station-related battery references and other Queensland battery projects), but nothing that clearly identifies the 250 MW / 500 MWh Darling Downs Battery's total greenfield investment cost. Because of that, no capex, O&M, or other operating assumptions are populated beyond the zero-emissions battery default.
