Notes
No generator-specific capex, O&M contract, battery supply/EPC price, financing close, offtake/tolling agreement, or commercial operation date was found. Augusta BESS appears to remain in development/public consultation rather than committed/operational: AEMO lists it as a publicly announced storage development, and SA DEM lists its HRE Act consultation as closed on 10 March 2026. Capex is therefore a technology-default estimate, scaled to 270 MW / 540 MWh using GHD's 2025 AEMO draft cost parameters for a 2-hour standalone LFP BESS with dedicated grid connection: AUD 410/kW power component + AUD 290/kWh energy component + AUD 10m land/development allowance. The estimate excludes any site-specific network augmentation, financing costs, IDC, owner contingency, taxes, or project-specific EPC/battery procurement differences unless included in the generic benchmark. Fixed O&M uses GHD's 2-hour BESS fixed O&M plus extended warranty allowance: AUD 10,000/MW-year + AUD 5,000/MW-year = AUD 15,000/MW-year. Variable O&M is set to 0 because GHD includes variable O&M in fixed O&M. Emissions intensity is direct operational emissions only; lifecycle/embodied emissions and Scope 2 emissions associated with charging energy are not included. No firm closure date or refurbishment plan was found; closure/rehabilitation is covered in the Statement of Environmental Objectives, and the default economic/technical life is 20 years.
