Notes
Project-specific capex could not be found in owner/government materials. The $110 million figure is the GenusPlus EPC contract value reported for the 200 MW / 800 MWh Koolunga BESS, which is a construction contract proxy rather than a disclosed total project investment; it was used as the best available reported project-specific figure. Fixed OPEX used server-side fallback because no plant-specific O&M was found. Battery assets have no fuel cost or heat rate; emissions intensity assumed zero. The project is reported as due to reach commercial operation in 1H 2028, so the commissioned/online date of 2026-06-01 appears inconsistent with sourced information.
