Notes
No public project-specific EPC contract value, total capex, fixed O&M or variable O&M was found for Barnawartha Solar & Energy Storage. Capex is estimated for the solar PV component only, excluding the co-located BESS, using Aurecon/AEMO 2024 large-scale solar PV single-axis tracking benchmark: AUD 1.15/Wdc EPC plus land/development cost equal to 10% of equipment cost. Gentari reports 88 MWp installed solar capacity and 64 MW/2-hour BESS, while the project website and CIS list the solar component as approximately 64 MW AC and BESS as 64 MW / 148 MWh. Estimated solar capex = 88 MWp * AUD 1.219 million/MWp = AUD 107.27 million nominal 2024 basis; capex_per_mw_aud uses the user-provided 64.02 MW AC capacity. Fixed O&M is estimated as AUD 12,000/MWp-year * 88 MWp = AUD 1.056 million/year, converted to AUD/MW-year using 64.02 MW AC. Variable O&M is reported by the benchmark as included in fixed O&M and is therefore entered as 0. Direct operational emissions intensity for solar generation is assumed 0 tCO2/MWh; avoided-emissions claims are not used as stack emissions intensity. No generator DUID was found; project timeline indicates financial close in early 2026, construction mobilisation late 2026 and energisation/operation in 2027. Major end-of-life/closure notes are generic: large-scale solar PV retirement benchmark assumes decommissioning, dismantling and rehabilitation over about 22 weeks with retirement cost around AUD 110,000/MW at end of technical life.
Barnawartha is under development, not yet operational. Official project sources state up to about 64 MW AC solar with battery storage; Gentari lists 88 MWp solar and 64 MW/2hr BESS, while AEMO Services' CIS Tender 1 table lists 64 MW generation and 148 MWh storage. No public project-specific capex, EPC contract value, O&M contract price, financing terms, fixed O&M, variable O&M, heat-rate/efficiency, or closure-cost values were found. The capex estimate is solar-only and excludes the co-located BESS: derived from AEMO/Aurecon 2024 large-scale single-axis tracking solar PV cost assumptions of AUD 1.15/Wdc EPC plus land/development cost equal to 10% of equipment cost, applied to Gentari's stated 88 MWp DC capacity. Fixed O&M is estimated from the same AEMO/Aurecon solar PV assumption of AUD 12,000/MWp-year, applied to 88 MWp. Capex per MW and fixed O&M per MW-year are expressed against 64.02 MW AC capacity supplied in the prompt. Variable O&M is set to zero because AEMO/Aurecon states it is included in fixed O&M. Heat rate and thermal efficiency are not applicable to solar PV. Emissions intensity is treated as direct operational Scope 1 intensity of 0 tCO2e/MWh, consistent with solar PV operation and CER solar facility reporting examples. Major refurbishment/closure notes: no project-specific refurbishment or closure plan was found; generic AEMO/GHD solar PV assumptions indicate 30-year economic life and solar PV retirement activities covering decommissioning, dismantling and rehabilitation.
No public generator-specific EPC contract price, project-finance capex, fixed O&M contract, or variable O&M contract was found. Capex is an estimate for the solar PV component only, excluding the 64 MW/148 MWh BESS and excluding the separate overhead line permit estimate. It is based on Gentari's reported 88 MWp solar capacity and Aurecon/AEMO 2024 NEM mid-size ground-mount single-axis-tracking solar assumptions: EPC cost AUD 1.30/Wdc plus land/development cost equal to 10% of equipment cost, where equipment is 60% of EPC. Using 88 MWp gives EPC AUD 114.4m plus land/development AUD 6.864m, total AUD 121.264m in nominal 2024 AUD. Capex per MW uses the user-provided 64.02 MW AC capacity. Fixed O&M uses AUD 12,000/MWp-year applied to 88 MWp. Variable O&M is treated as zero because the cited AEMO/Aurecon assumption states it is included in fixed O&M. Project status: under development; current project website indicates financial close in early 2026, construction mobilisation in late 2026, and energisation/site operational in 2027. DUID was not located in public search results, consistent with the project not yet being operational/registered in AEMO dispatch data as of the researched sources.
