Notes
Original 1983 construction cost for Bastyan was not found in public web sources reviewed. The capex_total_aud field therefore uses the reported indicative value for the Bastyan Power Station refurbishment in the Tasmanian Infrastructure Project Pipeline, not original construction cost and not a full replacement cost. Hydro Tasmania's current West Coast refurbishment program says Bastyan upgrades are scheduled End 2027 to Mid 2028, with work expected to start in November 2027; tasks include turbine component replacement, governor refurbishment, intake gate refurbishment, control/monitoring modernisation and turbine power supply replacement. Hydro Tasmania's 2024-25 annual report separately reports $4.67m spent/planned in FY2024-25 at planning/procurement stage for the Bastyan station upgrade. No closure date was identified. Fixed O&M, variable O&M, asset life and emissions intensity are technology-default assumptions for conventional hydropower because generator-specific O&M, efficiency, heat-rate and emissions-intensity data were not publicly identified. Heat rate is not applicable to water-driven hydro generation; site-specific hydraulic/turbine efficiency was not reported.
Original 1983 construction cost for Bastyan was not found in accessible web sources. The capex value is therefore not the historical build cost; it is an estimated 2024 AUD replacement/redevelopment proxy using Aurecon/AEMO conventional hydropower benchmark cost of AUD 5.25m/MW construction plus 10% development cost, scaled to the provided 79.9 MW capacity. Hydro Tasmania states Bastyan was commissioned in 1983, has one Francis turbine and 81 MW capacity, and is part of the Anthony-Pieman West Coast refurbishment program. Bastyan upgrades are scheduled for end-2027 to mid-2028, with design/supply commenced and work expected to start in November 2027. Hydro Tasmania's 2024-25 annual report separately reports AUD 4.67m spent in FY2024-25 on Bastyan station upgrade planning/procurement; this is a refurbishment program spend to date, not total project capex. Fixed and variable O&M, efficiency, life and capex are technology-default estimates, not Bastyan-specific reported values.
Bastyan-specific original 1983 construction cost was not found in public sources. The reported capex_total_aud is Hydro Tasmania's FY2024-25 spend on the Bastyan station upgrade at planning/procurement stage, not the original construction cost nor total refurbishment project cost. Hydro Tasmania also reports an aggregate first-round West Coast upgrade investment of approximately AUD 200 million in 2023 dollars across Mackintosh, Bastyan and Reece two units, intended to add around 40 MW of flexible capacity and about 40 years of asset life to each asset; a simple pro-rata allocation would imply about AUD 50 million for Bastyan, but that is not used as the reported capex field. Fixed and variable O&M are technology default estimates derived from IRENA/EIA hydropower benchmarks because no Bastyan-specific O&M split was found. Emissions intensity is treated as zero direct operational combustion emissions for hydro-water generation; Hydro Tasmania notes lake/reservoir emissions remain subject to quantification methodology and are not included.
