Notes
No reliable plant-specific greenfield capex announcement was found for Ladbroke Grove. The plant is an existing Origin gas peaker in South Australia; public sources confirm it was operational in 2000 and currently 80 MW total across the station, but no owner-reported original construction cost was located. For operating assumptions, AEMO heat-rate data lists Ladbroke Grove at 11.88 GJ/MWh (as-generated, HHV). AEMO/Aurecon 2024 OCGT benchmark for a large GT gives fixed O&M of $17,368/MW-year and 25-year design life; this was applied to the 40 MW unit as a fallback. Emissions intensity is set to the provided default because no better plant-specific emissions factor was found in the searched sources.
