Season 3 of AEMO On Air is underway 🎙️

In the first episode for 2026, we speak with Kerry Galloway, AEMO’s Manager of Market Insights, about a milestone quarter for Australia’s energy transition following the launch of AEMO’s Q4 2025 Quarterly Energy Dynamics (QED) report.

For the first time ever, renewables and storage supplied more than half of total energy needs across the east and west coast grids in Q4, with WA’s WEM reaching an extraordinary 91% renewable supply at peak. Strong renewable output contributed to lower wholesale prices — while remaining just one of several factors that shape the market.

The episode also explores the continued surge in investment, from grid-scale solar and batteries to rooftop systems on Australian homes. Battery discharge nearly tripled year-on-year in the NEM and jumped around 200% in the WEM, while rooftop solar growth is increasingly influencing daytime demand and minimum operational demand.

Combined with milder conditions than Q4 2024, the quarter highlights sustained momentum and real change in the energy mix.

Australia’s electricity system is transforming at speed and the choices made, specifically in the coming decade, will shape costs, reliability and emissions outcomes for generations.

In this episode of AEMO On Air, we sat down with Nicola Falcon, AEMO’s Executive General Manager of System Design, to unpack the Draft 2026 Integrated System Plan (ISP) and the big themes shaping this story.

With electricity demand forecast to nearly double by 2050, driven by electrification of homes, industry and transport, plus rapid growth in data centres, the draft ISP lays out a clear, least-cost roadmap to replace retiring coal while keeping the lights on.

We dig into why renewables, firmed by storage, backed up by gas and connected with networks remains the least-cost and reliable pathway, and how today’s investments in rooftop solar, batteries, large-scale renewables and networks are already lining up with that plan.

And Nicola explores what’s changed since the last ISP, including technology costs, along with deeper analysis on gas supply infrastructure and distribution network cost to support further consumer energy resource benefits.

This week we released the 2025 Transition Plan for System Security (TPSS) and in our latest episode of AEMO On Air, Chris Davies, AEMO’s Group Manager – Future Energy Systems, unpacks what it means for Australia’s energy future.

As coal power stations continue to exit the power system, replacement system security services are needed to unlock the growing potential of renewable energy, including rooftop solar, to help deliver a smooth transition for consumers.

Chris also reflects on the renewable success story that is South Australia, and what its experience means for the rest of the National Electricity Market (NEM).
