How this was derived
Annual fixed OPEX computed from the selected per-MW fallback and the project capacity.

Fixed OPEX / MW-yr

Reported / source value
$10.8k (2024 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
The review gives BESS fixed O&M costs by duration case; 4-hour storage corresponds to $12,800/MW-year total annual O&M excluding extended warranties, and the annual totals are presented on the same table. Conservatively, a lower-end fallback of $10,800/MW-year is used for this project because the site-specific duration is 2 hours and variable O&M is not separately specified.

Notes
No project-specific greenfield CAPEX figure was found in official owner/developer or government sources. ACEnergy’s project page lists Apsley BESS as 120 MW and 264 MWh; the portfolio page also lists developer ACEnergy and owner Valent Energy, which conflicts with the user-provided owner name ACENergy Pty Ltd, so owner identity should be reviewed. For battery O&M, the 2024 AEMO/Aurecon review provides fixed O&M of $10.8k/MW-year for the 4-hour BESS case and indicates variable O&M is not typically separately specified for BESS long-term service agreements. Asset life assumed at 20 years from the AEMO/Aurecon battery case.
