Notes
No web search results were returned for this specific generator, so no generator-specific financial or operating assumptions could be source-verified. For a battery storage asset, fuel cost, heat rate, and direct emissions intensity are generally not applicable; emissions intensity is set to 0 only as a technology default, not as a site-specific reported value. Major refurbishment or closure notes unavailable.
Specific official capex and O&M figures were not found in Flow Power, Zenviron or Monadelphous disclosures. Capex uses a third-party Projectory report describing the project as a $150m Gippsland battery project; official Flow Power/Zenviron sources confirm financial close, scope, contractor roles and construction/commercial-operation timing but not the dollar value. Capex per MWh is calculated against the user-provided 200 MWh storage capacity; the latest official financial-close and contractor sources also state 100 MW / 223 MWh, which would imply about AUD 672,646/MWh. O&M, round-trip efficiency and asset life are technology default estimates from Aurecon's 2024 Energy Technology Cost and Technical Parameter Review for a 2-hour large-scale lithium-ion BESS, scaled to 100 MW. Fixed opex includes Aurecon's 2-hour BESS fixed O&M of AUD 8,000/MW-year plus indicative 20-year extended warranty of AUD 5,300/MW-year. Variable O&M is left null because Aurecon states BESS long-term service agreements are not typically based on fixed/variable splits. Direct operational emissions are treated as zero for battery storage; lifecycle and charging-energy emissions are market-dependent and not included. Closure/refurbishment: Aurecon indicates 20-year economic/design life, possible extension to about 25 years after condition assessment, and further life extension with battery upgrades; no Bennetts Creek-specific closure date was found. Current project timeline: planning permit Q4 2023, GPS approval Q1 2024, financial close Q4 2025, construction commences Q1 2026, commercial operation expected 2028.
