Notes
I could not find a plant-specific greenfield capital cost for the Tamworth BESS Project 1 Pty Ltd / Kingswood project in the sources searched. The strongest current evidence found indicates the nearby Kingswood Battery Energy Storage System (Iberdrola) is 270 MW / 1,080 MWh and an estimated A$458 million investment, but that is a different owner/entity and should not be assigned to this generator without confirmation. For battery O&M, I used AEMO/Aurecon 2024-25 indicative fixed O&M of A$51,000/MW-yr and variable O&M of nil; asset life was not explicitly sourced.
