Notes
Plant-specific capex could not be found from the owner/developer directly, but a Queensland government-backed regional investment page lists Gawara Baya Wind Farm project value at $1.2 billion. The project is described as a 400 MW wind farm on the project website, while the DUID provided here is 104 MW battery storage; therefore the $1.2 billion figure appears to cover the broader wind project/precinct, not the battery DUID alone. I have used the provided fallback battery O&M defaults because no project-specific battery O&M data was found. Technology assumptions are for a grid-scale lithium-ion BESS; emissions, heat rate and fuel cost are not applicable.
