In Australia, the real value of these big batteries is not necessarily to provide emergency power, but more to respond in milliseconds to variations in demand and to smooth out the 5 minute spot market.
Having a sink and a source for spikes aids grid stability and somewhat helps to reduce the need to build more infrastructure to handle transmitting power from the generators during those peaks.
It also helps avoid the viability of gas powered generators which are very expensive and carbon intensive.
