Notes
Identity and DUID capacity are source-backed to BARRON-1, 35 MW, in service, run-of-river hydro. Plant-level CleanCo factsheets state Barron Gorge is a 66 MW station with two 33 MW generators, commissioned in 1963; this differs slightly from the 35 MW DUID capacity used for BARRON-1. The capex field uses a historical reported construction estimate of £2.055 million for the present station, converted at the official decimal conversion of A£1=A$2 to A$4.11 million nominal; this is low-confidence because it is from secondary historical sources, not an original construction account. The fixed O&M and variable O&M assumptions are not generator-specific; they are default/estimated values from Aurecon/AEMO 2024 conventional hydropower cost parameters, scaled to the 35 MW DUID. Variable O&M is set to 0 because the source states variable O&M is included in fixed O&M. Major refurbishment: Queensland Government sources report a $28 million refurbishment/upgrade completed by Stanwell in 2011, extending the power station life by 40 years; another source says the first stage in 2005 was just over $13 million. CleanCo reported significant Kuranda Weir damage from Tropical Cyclone Jasper in December 2023, with the station rendered inoperable, returned to service in July 2024, a butterfly valve outage returning to service on 7 May 2025, and Phase C recovery works continuing into 2026. Closure assumptions conflict: NEMStats reports expected closure year 2063-07-02 for BARRON-1, while the 2011 refurbishment life-extension note implies life extension to roughly 2051; CleanCo's 2024 news also referred to supporting generation for another 60 years, but this is treated as narrative rather than a formal closure date.
Barron Gorge Power Station is a 66 MW run-of-river hydro station with two 33 MW generators commissioned in 1963; AEMO lists BARRON-1 as Barron Gorge Power Station Unit 1. The user-provided DUID capacity is 35 MW, while owner material states two 33 MW generators and 66 MW station capacity. The reported $28 million refurbishment was station-level, not explicitly allocated by DUID; capex_per_mw uses 66 MW station capacity. Fixed O&M and VOM are not generator-specific; they use AEMO/GHD 2025 conventional hydropower assumptions and pro-rate annual fixed opex at 35 MW for BARRON-1. Heat rate and thermal efficiency are not meaningful for hydro and are left null. Scope 1 emissions intensity is calculated from CleanCo FY24 site emissions: 239 t CO2-e / 93,872 MWh = 0.00255 tCO2-e/MWh; direct combustion emissions for hydro generation itself are otherwise generally nil. No closure date found; CleanCo reported major recovery, valve, PLC and weir works, and the earlier refurbishment extended life by 40 years.
Barron Gorge is a 66 MW CleanCo hydro station commissioned in 1963; BARRON-1 is one NEM unit reported by NEMStats at 35 MW. No DUID-specific construction capex, O&M, heat-rate or efficiency source was found. The reported 1959 capital cost is for the Barron River hydro-electric extension first stage, not separately for BARRON-1; it is preserved as nominal historical AUD by converting £5.85 million to A$11.7 million at decimal conversion parity of A£1=A$2, and capex_per_mw uses the current station capacity of 66 MW. For DUID-level fixed O&M annual cost, the Aurecon/AEMO conventional hydro default of AUD 105,000/MW-year is multiplied by the user-provided 35 MW unit capacity. Variable O&M is set to 0 because Aurecon states conventional hydro VOM is included in fixed O&M. Emissions intensity is calculated from CleanCo FY24 reported Barron Gorge Scope 1 emissions of 239 tCO2-e divided by 93,872 MWh exported, giving 0.00255 tCO2-e/MWh; this is a site-level Scope 1 intensity rather than a market dispatch emissions factor. Heat rate is not applicable for hydro generation and is left null. Efficiency was not found for Barron Gorge; although refurbishment sources refer to improved efficiency, no numeric turbine/generator efficiency was found. Refurbishment notes: Queensland Government reported a $28 million upgrade/recommissioning in 2006 extending major component life by 40 years; a 2015 statement says the refurbishment was completed in 2011. CleanCo FY25 reported Kuranda Weir recovery works after ex-Tropical Cyclone Jasper, Barron Gorge major valve replacement and PLC upgrade, and a temporary outage resolved with return to service on 7 May 2025.
