Notes
Specific financial data for Bayswater Power Station is not readily available in public documents. Defaults or estimates may be used.
BW02-specific original construction capex was not located in public sources. The capex value used here is an allocated estimate: one quarter of the reported AUD 129 million Bayswater turbine efficiency upgrade capital investment value, because the project covered Bayswater's four turbine sets. AGL's 2018 announcement also referred to spending more than AUD 200 million to upgrade and maintain Bayswater; this is broader than the EIS turbine-efficiency capital investment value and likely includes maintenance/sustaining scope. Fixed and variable O&M are not Bayswater-specific reported values; they use AEMO/GHD black-coal technology defaults in real 2018-19 AUD. Emissions intensity uses Bayswater EIS reported 0.93-0.95 tCO2e/MWh sent-out midpoint. Asset life is inferred from 1985 commissioning to AGL's targeted closure by end-2033; AGL's 2015 presentation also identified Bayswater end of technical life as 2035. Major refurbishment/closure notes: AGL completed/announced a AUD 63 million DCS project, AUD 70 million reliability and safety systems works, a station-wide turbine efficiency upgrade, and a reported AUD 130 million planned overhaul of one unit in 2025; Bayswater is scheduled to close by the end of 2033.
Capex is the reported first-stage Bayswater Electricity Project cost for construction of 2 x 660 MW units plus associated coal and water supplies, stated in June 1979 prices; no public full four-unit original construction capex or BW02-only capex was located. Capex per MW is calculated as AUD 590m / 1,320 MW = AUD 446,970/MW in June 1979 price terms, not escalated. Fixed opex annual value is derived for BW02 at 685 MW from AEMO planning FOM AUD 54.05/kW-year: 685,000 kW x 54.05 = AUD 37.024m/year; the underlying AEMO/IEEFA table is station-level and modelling-oriented, not owner-reported actual spend. Variable O&M, heat rate and fuel cost are AEMO planning assumptions reproduced in a public report, not audited plant actuals. Efficiency is calculated from heat rate as 3.6/9.45 = 38.1% HHV sent-out. Emissions intensity uses the Clean Energy Regulator FY2023-24 facility reported value for Bayswater Power Station. AGL FY25 reporting says asset management plans support closure by end-2033, giving about 48 years from 1985 commissioning to 2033 closure. Major works include >AUD 200m turbine upgrade/maintenance program, AUD 63m DCS approval, and 2025 reliability/flexibility programs including Bayswater low-pressure heater replacement and minimum load reduction for Unit 2 to 170 MW.
No reliable public source for original 1985-86 construction cost of BW02 was found. Capex is therefore recorded as an estimated allocation of the reported more-than-AUD 200 million four-unit Bayswater turbine efficiency/maintenance upgrade; approximately AUD 50 million per unit is allocated to BW02, which AGL reports as one of the 25 MW unit upgrades completed by FY22. This is refurbishment/upgrade capex, not original construction capex. Fixed and variable O&M are default estimates from AEMO/Aurecon 2024 AUSC black-coal new-entrant parameters, not Bayswater-specific operating accounts. The fuel cost field uses the Bayswater-specific AEMO coal-price assumption cited by IEEFA; AGL’s FY25 aggregate coal fuel cost is included as a cross-check but not used as the profile value. Asset life is inferred from commissioning in 1985 and targeted closure by end-2033; exact BW02 online date was not located.
