Notes
Public web search found the Gullen BESS project page indicating a proposed standalone battery energy storage system of up to 300MW/600MWh co-located with Gullen Range Wind Farm, but no reliable project-specific total construction/investment cost announcement was located. Because no plant-specific capex or operating cost figures were verified, internal fallback values were not applied here. The project appears to be proposed/in planning rather than a confirmed commissioned asset in the retrieved sources.
