How this was derived
Confirms Stage 2 / West is part of the larger 1,333 MW mega-project, but does not give a West-only AUD cost.

Notes
Reported project cost for the full Golden Plains Wind Farm appears to be about A$4 billion, with sources describing Golden Plains as a 1,333 MW project and Stage 2/West as part of the larger development. West stage construction commenced in mid-2024 and is described as ~574 MW / 577 MW in project materials; the owner/developer sources did not provide a separate West-only capital cost, so the full-project reported cost was allocated to this site as the best available plant-level proxy. O&M values were not plant-specific, so server defaults were used for wind onshore.
