Even if it was ever used at a 1C discharge rate. Which we have never seen since some brief tests during commisioning. There was a brown out event when one of the thermal generators suddenly went offline due to extreme unmet demand and the BigBattery was seen to chip in 50 MW in brief spurts off and on for 2 hours. Mining the $2,000/ MWh peaks and really making only an intermittent 2.5% contribution. 50MW is hardly going to break the backs of any thermal supply in a 2GW grid that is only having problems with frequency support due to having prematurely shuttered too much of their previously reliable thermal generation in favor of unreliable wind.
The cost of power from the thermal units exceeds Australia's GDP.
