Notes
Project-specific reported capital cost of about AUD 209 million was identified for the 150 MW/437 MWh Armidale BESS. The project is scheduled to complete in 2027 / go online in 2028 in the sources consulted; capex year is set to the 2025 approval/announcement year because the source figure appears in that context. Fixed O&M and variable O&M use the provided internal defaults because no plant-specific operating cost was found. Battery assets have no fuel cost or heat rate; emissions intensity is set to zero.
