Notes
No Bashan-specific capex, O&M, financing, heat-rate, emissions-intensity or refurbishment budget was found. Financial values are default/benchmark estimates for a new Australian onshore wind project, scaled to the user-supplied 460.2 MW capacity. Latest public project sources conflict on capacity: EPA Tasmania states 434 MW and up to 56 turbines; the Bashan project website states up to 450 MW; the user supplied 460.2 MW. Capex estimate uses GHD/AEMO 2025 onshore wind benchmark of AUD 3,150/kW net construction capex, excluding GST, contingency/escalation and site-specific costs; land/development allowance may add approximately 2.5% if included. Fixed O&M is scaled from GHD/AEMO benchmark of AUD 29,000/MW/year. Variable O&M is not separately stated because benchmark sources include it in fixed O&M. Asset life uses the GHD/AEMO 2025 benchmark economic/design life of 25 years; technical life extension to 30-35 years or repowering may be possible but is site- and fleet-specific. The project is still in assessment/pre-construction; no closure date, major refurbishment plan, DUID, or AEMO registration was found.
Bashan Wind Farm is still in development/assessment, not an operating NEM registered generator in the sources found; no DUID was identified. Official/project sources give varying capacity descriptions: EPA Tasmania says 434 MW and up to 56 turbines; Infrastructure Pipeline says up to 460 MW; the owner website says up to about 450 MW and 50-60 turbines. The financial values in this profile are not Bashan-reported costs: they are technology-default estimates scaled to the user-provided 460.2 MW using AEMO/GHD 2025 onshore wind benchmark assumptions of AUD 3.15m/MW capex and AUD 29,000/MW/year fixed O&M. Variable O&M is recorded as 0 because the AEMO/GHD source states variable O&M is included in fixed O&M. Heat rate and thermal efficiency are not applicable to wind generation. Major closure/refurbishment is not applicable yet; the project requires environmental approvals before construction, and generic onshore wind technical life may extend to 30-35 years or more with lifetime extension/repowering.
Bashan Wind Farm is a development-stage project, not an operating NEM DUID as at the source documents reviewed. No Bashan-specific EPC price, financial close capex, O&M contract price, PPA, fuel contract, heat-rate, or retirement date was found. Financial assumptions therefore use CSIRO/AEMO GenCost 2024-25 default Australian onshore wind values: 2024 capex AUD 3,351/kW, fixed O&M AUD 28/kW-year, variable O&M AUD 0/MWh, fuel AUD 0/GJ, and 25-year economic life. Capex total is calculated for the user-supplied 460.2 MW wind capacity only and excludes the optional 200-400 MWh BESS, connection upgrades beyond standard assumptions, site-specific Tasmanian logistics, and any IdentiFlight/eagle mitigation premium unless captured in generic wind costs. GenCost capital costs are stated as AC net power, before subsidies, for a location not greater than 200 km from the Victorian metropolitan area; Tasmania/Central Highlands conditions may differ materially. Major refurbishment/closure: project is not yet operating; GenCost discusses onshore wind being rebuilt at 25 years for LCOE analysis and notes Aurecon suggests a possible 30-35 year technical life for onshore wind.
