Ararat Wind Farm (ARWF1)

Notes
Project-specific capex is reported inconsistently: GE reported the project as an approximately AUD 450 million development in 2015, while an Australian Industry Participation listing gives estimated project value AUD 411,042,241. The financial profile uses the AUD 450 million nominal 2015 construction-financing figure because it is tied to construction commencement and shareholder financing; the lower government procurement value is retained as a conflicting source. Fixed and variable O&M were not found as generator-specific public financial disclosures; values use AEMO/Aurecon 2024 onshore-wind defaults, scaled to the user's 240 MW capacity. AEMO's 2025 ELI lists ARWF1 maximum capacity as 241 MW and Iberdrola's current asset page states 242 MW; per user input and original construction sources, 240 MW is used for per-MW calculations. Heat rate and thermal efficiency are not applicable to wind generation. Emissions intensity is treated as 0 tCO2e/MWh for direct operational combustion emissions; minor auxiliary electricity and lifecycle emissions are excluded. No closure announcement was found. Major maintenance/refurbishment note: RelyOn reports a 15-year electrical balance-of-plant maintenance schedule for Ararat, including 2024 outage look-ahead; Aurecon notes wind turbines typically have 20-25 year design life and investors may assume 30-35 years with life extension and higher later-life maintenance.
