Notes
No project-specific financial close, EPC contract price, O&M contract price, turbine supply agreement, or closure/decommissioning provision was found in public sources. Capex and O&M are estimated from AEMO/Aurecon 2024 onshore-wind benchmarks scaled to 228 MW and adjusted using Aurecon's Biloela location/O&M factors. Calculation: base EPC AUD 3.170m/MW x 228 MW x 1.15 Biloela revised location factor = AUD 831.174m; land/development allowance = 2.5% of base EPC = AUD 18.069m; estimated total = AUD 849.243m. Fixed O&M calculation: AUD 28,000/MW-year x 1.26 Biloela O&M factor = AUD 35,280/MW-year; x 228 MW = AUD 8.044m/year. Variable O&M is reported as 0 only because Aurecon treats onshore-wind variable O&M as included in fixed O&M, not because no variable maintenance costs exist. Current schedule is uncertain/conflicting: the user-provided online date is 2026-12-01; Powerlink's November 2025 connection newsletter indicates connection construction from September 2026 pending approvals; the project website says construction is planned to start in 2027; Banana Shire Council still lists construction start 2024 and end 2027. No generator-specific closure date was found; wind technical/operational life is assumed at the low end of Aurecon's 30-35 year range, with economic/design life 20-25 years.
No current FID/construction-cost disclosure for the 228 MW / 41-turbine Banana Range Wind Farm was found. The capex estimate uses AEMO/Aurecon 2024 onshore-wind benchmark EPC cost of AUD 3,170/kW applied to 228 MW, excluding land/development costs. If adding Aurecon's illustrative land and development allowance of 2.5% of CAPEX, total estimated capex would be approximately AUD 740.8 million. A historical 2019 media report cited US$240 million for an earlier 180 MW / 50-turbine approved scope; this is superseded by the current 228 MW / 41-turbine design and is not used as the main capex assumption. Current owner/developer evidence indicates EDF acquired the project from Goldwind Australia and Lacour Energy in May 2021, while the original vehicle/owner name Orange Creek Energy Pty Ltd appears in older development materials. Project website timeline indicates financial close in 2025, construction in 2026 and operation in 2027; this conflicts with the provided online date of 2026-12-01 and should be reviewed. Major end-of-life assumption: onshore wind technical life 30-35 years with life-extension assessment; GHD estimates retirement costs at AUD 152,000/MW for a representative onshore wind farm, but this is not included in capex or opex fields.
