Notes
Project-specific reported capital cost found in NSW Government planning release: $209 million Armidale BESS, 150 MW / 437 MWh, approved for construction in December 2025, scheduled for completion in 2027. Used owner/developer project page and NSW Government release; no separate refurbishment cost found. Fixed O&M used server-side fallback because no plant-specific O&M figure was located in search results. The owner identity in the prompt ('Elgin EnergyP/L') appears not to match the current project website branding ('Valent Energy'); this may indicate a naming/ownership mismatch and should be reviewed.
