Notes
No specific financial data found for Beelbee Solar Farm. All values are marked as unknown due to lack of available information.
Beelbee Solar Farm is listed as publicly announced with 200 MW capacity, no DUID and no full commercial use date. No generator-specific construction cost, O&M, heat-rate/efficiency, emissions factor, or closure/refurbishment disclosure was found. Financial assumptions therefore use AEMO/Aurecon 2024 large-scale solar PV single-axis tracking hypothetical project values, which are an exact 200 MW AC / 240 MWp DC reference case. Capex total is estimated as EPC cost AUD 276.0m plus land and development AUD 16.56m = AUD 292.56m, equivalent to AUD 1.4628m/MW AC. Fixed O&M is source-reported as AUD 12,000/MWp DC-year and AUD 2.88m/year for 240 MWp; normalised here to AUD 14,400/MW AC-year for a 200 MW AC plant. VOM is set to 0 as a separate line item because Aurecon states variable O&M is included in fixed O&M. Heat rate and thermal efficiency are not applicable to solar PV. Direct operational emissions intensity is entered as 0 tCO2/MWh on the basis that solar PV uses no combusted fuel; lifecycle emissions are not included. Closure/decommissioning: GHD's 2025 AEMO retirement review uses a 200 MW AC single-axis tracking PV scenario, estimates technical/economic life at 30 years, notes possible 40-year operation if piles do not corrode and spare parts remain available, and estimates retirement cost at AUD 110,000/MW with about 22 weeks total retirement duration. Older public reporting conflicts on project size, citing 150 MW potential, 240 MW approved, or 250 MW; current AEMO-derived listings use 200 MW.
Beelbee Solar Farm appears to remain a pre-construction/publicly announced project rather than an operating NEM generator: no DUID, online date, FID announcement, EPC contract, commissioning notice, expected closure year, or closure date was found. The best Beelbee-specific capex source found is a Western Downs regional development status report listing Darling Downs Solar Farm - Stage 2 at Beelbee with construction cost of AUD 395m for a 240 MW solar farm with potential 110 MW battery storage. This conflicts with the current 200 MW nameplate capacity in Global Energy Monitor and the user-provided generator record; capex_per_mw_aud is therefore calculated on the 240 MW reported capex scope, not the 200 MW current listing. Fixed O&M, variable O&M, fuel cost, asset life, heat-rate, efficiency and refurbishment assumptions are AEMO/Aurecon technology defaults for a 200 MW AC / 240 MWp DC single-axis tracking solar PV project, not Beelbee owner-reported values. Major refurbishment/closure: no Beelbee-specific refurbishment or closure plan was found; AEMO/Aurecon default design life is 30 years, with possible technical extension to about 40 years if piles do not corrode and spare parts remain available.
Beelbee appears to remain publicly announced/pre-construction, with no DUID, full commercial use date, expected closure year or closure date found. The selected capex value is the most detailed Beelbee-specific construction-cost source found: Western Downs Development Status Report January 2019 lists Darling Downs Solar Farm - Stage 2 at Beelbee as a 240 MW solar farm with potential for 110 MW battery storage and construction cost of $395m. A separate TSBE renewables fact sheet gives a rounded '$400m Beelbee Solar Farm' figure; both are included. Capex per MW is calculated on the reported 240 MW scope to preserve the original source scope; if divided by the current 200 MW generator listing, it would be $1.975m/MW. O&M, variable O&M, fuel, life and refurbishment assumptions are AEMO/Aurecon technology-default assumptions for a 200 MW AC / 240 MWp DC single-axis tracking solar PV project, not Beelbee owner-reported values. Major refurbishment/closure: no Beelbee-specific refurbishment or closure notice was found; AEMO/Aurecon indicate 30-year life, possible extension to around 40 years subject to condition/spares, with midlife inverter refurbishment, tracker/pile works, substation sustaining capex and SCADA replacement likely life-extension items.
Beelbee Solar Farm is listed as Publicly Announced / pre-construction with no DUID, no full commercial use date and no closure date located. The 2024 TSBE Western Downs Development Status Report lists Beelbee Solar Farm as approved and awaiting commencement with APA Group as proponent and a construction cost of AUD 200 million; this is used as the generator-specific nominal capex assumption for a 200 MW AC NEM listing. A conflicting older TSBE report describes Darling Downs Solar Farm Stage 2 at Beelbee as a 240 MW solar farm with potential battery storage and AUD 395 million construction cost; this may reflect a wider or earlier scope and is not used as the primary capex value. Fixed and variable O&M, asset life and technical assumptions are default/benchmark estimates from Aurecon's 2024 technology-cost review for AEMO for a 200 MW AC / 240 MWp single-axis tracking solar PV project. Heat rate is not applicable for solar PV. Emissions intensity is interpreted as operational/direct generation emissions, not lifecycle emissions.
Beelbee Solar Farm appears in AEMO-derived generator lists as publicly announced / pre-construction rather than in service, with no DUID, full commercial use date, expected closure year, closure date, or final investment decision found. The best Beelbee-specific construction-cost source found is a regional development status report listing Darling Downs Solar Farm - Stage 2 / Beelbee as a 240 MW solar farm with potential battery storage and construction cost of $395m; this differs from the current AEMO/NEM listing capacity of 200 MW. Capex_per_mw_aud is therefore calculated on the reported 240 MW scope, not the 200 MW current listing. O&M, variable O&M, fuel, asset life and refurbishment assumptions are technology defaults from AEMO/Aurecon for a 200 MW AC / 240 MWp DC single-axis tracking solar PV project, not Beelbee owner-reported values. Major refurbishment/closure: no Beelbee-specific refurbishment or closure notice found; default solar PV life is 30 years, with possible extension to around 40 years if piles/spares remain suitable and with midlife inverter/tracker/substation refurbishment needs.
