Australia has built one of the world's most competitive battery storage markets — and it got there faster than almost anywhere else on the planet. What started as an experiment in South Australia in 2017 has grown into a mature, multi-gigawatt industry that is now redefining what grid-scale batteries can do.

In this episode of Transmission, host Wendel Hortop sits down with Jérémie Yvon, Head of Energy Management at Neoen Australia, to explore how one of the country's largest renewable energy companies is navigating the rapidly evolving battery landscape across both the National Electricity Market (NEM) and the Western Australian Electricity Market (WEM).

They cover the maturation of the Australian battery market, how Neoen structures battery revenue across two very different market designs, the rise of virtual batteries and firm renewable PPAs, long-duration storage investment, and why Jérémie believes battery oversupply is a credible - and under appreciated - risk.

You can watch or listen to new episodes every Tuesday and Thursday.
