Notes
Project-specific reported figure found for Elaine BESS financing/construction: A$460 million. The available sources identify this as the Elaine BESS project in Victoria and construction financing; the hybrid solar-farm-plus-BESS site description in user prompt appears to refer to the same Elaine project cluster. No plant-specific solar-plus-storage total EPC cost split was found in the searched sources, so the battery project financing figure is used as the best available reported capex proxy for the battery component. Asset life set to 15 years based on the financing/source context for the Elaine BESS. Fixed O&M was not separately sourced and thus left null rather than inferred from the fallback server default.
