Notes
Project-specific EPC/capex, O&M contract, battery supplier, tolling/PPA, and closure/refurbishment cost disclosures were not found. The capex and opex values are estimates scaled to the user-provided Phase 1 size of 140 MW / 140 MWh from Aurecon/AEMO 2024 large-scale lithium-ion BESS assumptions for a 1-hour 200 MW BESS with dedicated grid connection. Calculation: EPC = 140,000 kW x AUD526/kW power component + 140,000 kWh x AUD326/kWh energy component = AUD119.28m; pro-rata land/development allowance = AUD7.0m from AUD10m for 200 MW; total estimated capex = AUD126.35m. Fixed opex uses Aurecon's 1-hour BESS fixed O&M plus extended warranty allowance: AUD5,400/MW-year + AUD3,600/MW-year = AUD9,000/MW-year; for 140 MW = AUD1.26m/year. Variable O&M is treated as zero because Aurecon states BESS long-term service agreements are not typically fixed/variable. Emissions intensity is direct operational emissions only; indirect emissions depend on charging source and dispatch. Important scope caveat: 1414 Degrees' 2021 development approval staging identified Phase 1 as 140 MW / 140 MWh, but later/current SiliconAurora material describes a planned/approved 140 MW / 280 MWh BESS; this record follows the user's specified 140 MWh Phase 1. Closure/refurbishment: no project-specific closure date was found; technology default design/technical life is 20 years, with potential extension to about 25 years after condition assessment and battery upgrades. As of January 16, 2026, AEMO and ElectraNet had accepted proposed Generator Performance Standards for the 140 MW Aurora BESS, valid for 12 months subject to a Transmission Connection Agreement; final connection due diligence and TCA remained outstanding.
