Notes
No generator-specific capex, O&M, fuel contract, storage duration, online date, refurbishment plan, or closure date was found in the searched public sources. Identity and 300 MW capacity are sourced from NEM generation listings/NEMStats. Financial assumptions are technology defaults estimated from AEMO/Aurecon 2025 large-scale lithium-ion BESS assumptions. The estimate assumes a 300 MW / 1,200 MWh 4-hour LFP lithium-ion BESS with a dedicated grid connection and scales Aurecon's 200 MW / 800 MWh 4-hour BESS case linearly by 1.5. Capex includes EPC plus scaled land/development cost: (AUD 324.1m EPC + AUD 10.0m land/development) * 1.5 = AUD 501.15m. If the project is co-located with the separately listed Baking Board Solar Farm (MMT), Aurecon's co-located 4-hour case would imply a lower estimate of approximately AUD 485.0m including scaled land/development. Fixed O&M uses Aurecon's 4-hour fixed O&M plus 20-year extended warranty: AUD 4.24m per year for 200 MW, scaled to AUD 6.36m per year for 300 MW. Variable O&M is set to null because Aurecon states BESS long-term service agreements are not typically fixed/variable split. Efficiency is beginning-of-life round-trip efficiency at the point of connection, not thermal efficiency. Direct operational emissions are treated as zero; lifecycle and grid-charging emissions are excluded. Major refurbishment/closure: Aurecon assumes 20-year economic/design and technical/operational life; life may extend to about 25 years after condition assessment and further with battery upgrades.
