Notes
No generator-specific financial close, EPC contract, owner capex, fixed O&M contract, variable O&M contract, fuel/charging contract, or closure date was found for the Baldon Wind Farm Stage 2 BESS. The NEMStats record lists 'Baldon Wind Farm Stage 2 - BESS' as publicly announced with 500/1000 MW, but NSW planning sources for the broader Baldon Wind Farm list a smaller BESS of 200 MW / 400 MWh and DCCEEW CIS Tender 7 lists the successful Baldon project as wind + battery with 132 MWh. Because of this conflict, the financial profile uses the user's 500 MW / 1000 MWh nameplate as the modelling case, with capex and O&M estimated from Aurecon/AEMO 2024 2-hour lithium-ion BESS assumptions for a co-located renewable installation. Capex estimate scales Aurecon's co-located 200 MW / 400 MWh 2-hour BESS EPC cost of AUD 219.7m plus AUD 10.0m land/development cost by 2.5x to 500 MW / 1000 MWh. Fixed O&M includes Aurecon's 2-hour BESS fixed O&M of AUD 8,000/MW-year plus extended warranty of AUD 5,300/MW-year, scaled to 500 MW. Variable O&M is left null because Aurecon reports '-' and notes BESS long-term service agreements are not typically based on fixed/variable split. Efficiency is beginning-of-life round-trip efficiency at the point of connection, including auxiliaries. Emissions intensity is direct operational emissions only; indirect emissions depend on charging source and market dispatch. Major refurbishment/closure: Aurecon assumes 20-year economic/design and technical life for lithium-ion BESS, potentially extendable to about 25 years after condition assessment and further extendable with battery upgrades. The broader Baldon Wind Farm EIS states an overall project operational lifetime of approximately 35 years with decommissioning or refurbishment after that period, but this is not battery-specific.
