Notes
Project is proposed/under development. Owner filing states up to 270 MW and 1,080 MWh. Capex derived from the NSW planning portal estimated development cost, which is the plant-specific reported project cost available in search results. Fixed O&M taken from AEMO/Aurecon 2024 large-scale lithium-ion BESS benchmark for a 4-hour system; variable O&M not separately stated for BESS in the benchmark.
