Australia just doubled its battery storage capacity in twelve months—11 projects, 1.9GW, with Q4 alone delivering more storage than most countries deploy annually. But the deployment sprint is over, and the operational marathon has begun.

This keynote cuts through the deployment euphoria to examine where operational reality meets financial expectations, and what separates the assets that will thrive from those that will struggle in Australia’s unforgiving energy market.
