Reported / source value
$4.70M (2021 nominal)
Adjusted to 2026 real AUD using Australian CPI (All Groups).

How this was derived
SA Water explicitly reported a $4.7 million Bolivar anaerobic digester upgrade, which is a brownfield refurbishment rather than initial greenfield construction.

Notes
Plant-specific greenfield capex was not found for the full 7.5 MW unit. The only explicit project cost located was SA Water's $4.7 million Bolivar anaerobic digester upgrade (a brownfield refurbishment, not original plant construction), so that figure is captured as refurbishment capex rather than greenfield capex. Operating assumptions are based on AEMO/Aurecon 2024 bioenergy/waste-to-energy benchmarks, with Bolivar-specific evidence that the site uses biogas and on-site gas engines to generate electricity.
