Banimboola — NEM Generator

Financial overview

2026 real AUD. Monetary values are CPI-adjusted to 2026 real Australian dollars. Greenfield capex uses AEMO benchmarks when plant-specific cost is unknown.

Capex total (greenfield)	$23.00M How this was derived Primary news report provides the reported nominal project cost and construction/commissioning context in 2005. Reference $23m power station nearly up and running (high confidence)
Capex refurbishment	—
Capex / MW	$1,885,246 How this was derived Derived unit capex: 23,000,000 / 12.2 = 1.885 million AUD/MW, nominal 2005. Reference $23m power station nearly up and running (medium confidence)
Capex / MWh storage	—
Fixed OPEX (annual)	$575.0k How this was derived No Banimboola-specific O&M found. A midpoint/default 2.5% of AUD 23.0m capex gives AUD 575,000/year for the station. Reference Renewable Power Generation Costs in 2024 (low confidence)
Fixed OPEX / MW-yr	$47,131 How this was derived Default estimate only: AUD 575,000/year divided by 12.2 MW = AUD 47,131/MW-year. Reference Renewable Power Generation Costs in 2024 (low confidence)
Variable OPEX / MWh	$0.00 How this was derived No Australian Banimboola-specific VOM was found; zero/marginal VOM is a generic hydro modelling assumption. Reference Cost and Performance Characteristics of New Generating Technologies, Annual Energy Outlook 2020 (low confidence)
Fuel cost / GJ	$0.00 How this was derived Owner explanation supports treating water as non-purchased fuel for fuel-cost purposes. Reference Hydroelectric Power Stations (high confidence)
Heat rate GJ/MWh	— How this was derived Heat rate is a thermal-plant metric and is not applicable for Banimboola hydro. Reference Hydroelectric Power Stations (high confidence)

Notes
Reported capex is for the whole Banimboola Power Station, not just the 2.2 MW unit. AGL and ESC sources identify Banimboola as a 12.2 MW hydro power station comprising two 5 MW units and one 2.2 MW unit; therefore capex per MW is calculated as AUD 23.0m / 12.2 MW. The user-supplied 2.2 MW appears to be the small unit capacity rather than total station/DUID capacity. Fixed O&M is not generator-specific; estimated as 2.5% of reported capex per year, a midpoint/default within published hydropower O&M percentage ranges, and should be reviewed. Variable O&M and fuel cost are assumed zero/marginal for dispatch modelling because hydropower O&M is typically treated as fixed and there is no combusted fuel. Heat rate and thermal efficiency are not applicable to hydro. Emissions intensity is direct operational Scope 1 combustion emissions, assumed 0 tCO2e/MWh; lifecycle emissions can be non-zero and site-specific, particularly for reservoirs. No Banimboola-specific major refurbishment or closure notice was found; AGL describes the station as operating since 2005. AGL page lists average annual output as 11 GWh, while older secondary references report 35 GWh; AGL owner data is preferred.
