"Operating via the Hornsdale Power Reserve, it has helped to restore stability to the network . . .
It does not, and never will. A battery would normally be connected by a static inverter. As such, the connection provides no inertia and will not improve the stability of the system. In fact, by displacing conventional rotating plant, it may make it worse.

What exactly do you mean by "inertia"? A flywheel is not required if the transient emergency supply is instantaneous, as is that supplied by a very large battery. The reserve supply is available instantaneous. P.S. I have just come across this about GRID INERTIA, I suppose that is what you are referring to. Surely these days we can synchronise and stabilise the grid's frequency with accurate electronic systems, without the need for heavy rotating machines.
