Notes
No plant-specific greenfield capex figure was found in official owner or government sources. The project is the 150 MW / 300 MWh tranche of Equis's Calala BESS development; Equis states construction commenced on 20 June 2025 and overall build/commissioning is expected to take about two years. For the 2024 AEMO/Aurecon BESS benchmark, the nearest published case is a 200 MW / 2-hour BESS with fixed O&M of $5,600/MW-year implied from the $1.12m annual average fixed O&M for 200 MW; this was scaled to 150 MW for the requested site. CAPEX remains unpopulated because the available official sources did not provide a plant-specific total project cost for CABESS2.
