Notes
Capex is based on the asset-specific Foresight/ARENA knowledge-sharing report value of AUD 67.6m total project construction cost. Other public sources report similar but conflicting broader project values: ARENA project page AUD 70.1m total project cost, CEFC fact sheet AUD 69m, and Department of Industry AIP page AUD 60m estimated project value. Capex per MW uses 20 MW AC capacity. Fixed O&M and VOM are not generator-specific disclosures; they are technology defaults from Aurecon/AEMO 2024 large-scale solar PV single-axis tracking assumptions. Fixed O&M annual estimate applies AUD 12,000/MWp DC-year to the plant's 25 MW DC capacity, equivalent to AUD 300,000/year or AUD 15,000/MW AC-year. Variable O&M is treated as 0 because Aurecon states it is included in fixed O&M. Asset-specific operating notes include 2020-2021 voltage/reactive-control trip events, shutdown from 18 Aug 2021 to 22 Oct 2021, and rectification works via O&M contractor; no permanent closure notice was found.
Best generator-specific capex source is the 2022 ARENA/Foresight knowledge sharing report, which reports A$67.6m total project construction cost for the 20 MW AC / 25 MW DC plant. Earlier public sources conflict: CEFC described a A$69m project in December 2015, ARENA currently lists A$70.1m total project cost, and the Australian Industry Participation page listed an estimated A$60m value. The selected capex preserves the reported project construction cost and uses COD year 2017 as the capex year because construction ran Jan-Dec 2016, commissioning Dec 2016-May 2017, and commercial operation date was 20 May 2017. Capex per MW is calculated on the DUID/AC capacity provided by the user: A$67.6m / 20 MW = A$3.38m/MW. Generator-specific fixed and variable O&M dollar values were not found; therefore O&M uses the current Australian GenCost 2024-25 large-scale solar PV single-axis tracking default: fixed O&M A$12/kW-year and variable O&M A$0/MWh, giving A$240,000/year for 20 MW. The project-specific report identifies ENcome Energy Performance Australia Pty Ltd as O&M contractor and the Elecnor presentation notes an O&M agreement with 2+3 years term, but no O&M price. Heat rate and thermal efficiency are not applicable for solar PV; GenCost includes a 100% placeholder efficiency for large-scale solar PV LCOE modelling, not a module or thermal conversion efficiency. Operational Scope 1 emissions intensity is treated as 0 tCO2-e/MWh for solar PV. No closure or major refurbishment announcement was found; site-specific portfolio life is reported as 28.5 years from commissioning, implying natural retirement around late 2045 if measured from 20 May 2017 COD, absent life extension or repowering.
