I assume they used to fire up the coal plant to fill gaps but now use the battery which stores excess energy generated.

Edit:

The plant’s 185 megawatts of instantaneous discharge capacity match what the old coal plant could inject into the grid, though the batteries react far more quickly, with a 250-millisecond response time. Instead of generating power, they absorb it from the grid, ideally when it’s flush with renewable generation, and deliver that cheap, clean power back in the evening hours when it’s desperately needed.

Seems pretty clear to me.
