“HOWEVER, it turns out that Reneweconomy, in its zeal to promote new power sources, shifted the goalposts so that the battery output was exaggerated over one hundred fold. The correct measure is as follows with the battery contribution comprising the almost invisible yellow at the bottom of the following chart.

With Australia’s renewable energy crisis running totally out of control, whenever you hear the word ‘battery’ you know you’re being conned.
Pumping power into and then taking it out of a battery results in inevitable exchange losses, power gets chewed up during that process and is dissipated as heat energy.
