Financial overview

2026 real AUD. Monetary values are CPI-adjusted to 2026 real Australian dollars. Greenfield capex uses AEMO benchmarks when plant-specific cost is unknown.

Notes
No plant-specific greenfield capex announcement was found in the searched owner/developer, project, government, or market sources. Bundey is publicly described as a staged hybrid project; sources consistently indicate 300 MW / 1,200 MWh for Stage 1 battery, while the full project is described as 1,200 MW / 3,900 MWh across four stages. In the absence of a reported project cost, battery capex was left unset rather than substituting a benchmark. OPEX and technical assumptions were inferred from AEMO/GHD utility-scale BESS benchmark assumptions (200 MW / 800 MWh reference project) and scaled to 300 MW for a conservative planning default; these should be reviewed if a project-specific EPC/O&M package becomes available.
