From https://en.wikipedia.org/wiki/Hornsdale_Wind_Farm https://en.wikipedia.org/wiki/Hornsdale_Wind_Farm the battery can do 70MW for ten minutes and 30MW for three hours. They also say "capable of discharge at 100 megawatts" but that might be margin of safety. I wonder if things are limited by cooling? Maybe the battery only has enough cooling to sustain 30MW of output and doing 70MW for ten minutes is all heat soak.
