Stabilising the transition: Inside the 2025 Transition Plan for System Security
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).Read the full TPSS here: https://bit.ly/3XusYeCMedia Release: https://bit.ly/4rt4xMjInterviewer: Jonathon GeddesLinkedIn | X | Facebook

Why the world envies Australia’s transition plan: A deep dive into what is the ISP
Australia’s energy transition is accelerating and the next Integrated System Plan (ISP) will be central to guiding it. In this episode of AEMO On Air, we speak with Nicola Falcon, Executive General Manager – System Design, about how the ISP is developed, why it matters, and why it’s increasingly the envy of countries without a comparable long-term plan to navigate their transition. Nicola explains how the ISP provides a national roadmap for generation, storage and network investment through to 2050, built on more than a year of consultation with over 1,400 stakeholders and 240 submissions. She outlines what’s new in the Draft 2026 ISP, including expanded scope into distribution network opportunities and better integration with gas markets and how feedback has refined assumptions on consumer energy resources and infrastructure timing. The Draft 2026 ISP will be released on Wednesday, 10 December 2025. Interviewer: Catie Low LinkedIn | X | Facebook

Pedalling through change: System Security in a solar-driven grid
One in three Australian homes now have rooftop solar, that’s more than 4 million systems nationwide providing, on some days, over half of the east coast’s electricity. Australia is leading the world in distributed energy, with home batteries and electric vehicles rapidly changing how our power system operates. But as solar becomes a dominant force in the grid, maintaining stability and security presents new challenges. In episode two of AEMO On Air’s System Security series, Nij sits down with Jonathon Dore, AEMO’s Manager – DER Technical Integration, to explore how AEMO is working with industry and transition partners to maintain system security through the renewable transition and the critical challenges of managing high Distributed Energy Resources (DER) and Consumer Energy Resources (CER) penetration Jonathon explained system security using a simple analogy of something he loves: Maintaining system security is like riding a mountain bike on a trail. On the smooth sections, keeping the bike stable is almost effortless, but on the challenging sections, you need different skills and a different approach.

Inside the numbers: how renewables drove down power prices in Q3 2025
In this episode of AEMO On Air, we unpack the key findings from AEMO’s Quarterly Energy Dynamics (QED) report for Q3 2025 – a quarter defined by record renewable generation, greater market stability, and falling wholesale electricity prices across the NEM.AEMO’s Manager of Market Insights, Kerry Galloway, joins us to break down the data behind the trends, from new renewable records to what it all means for Australia’s evolving energy landscape.Renewables reached new highs, with record-breaking contributions across the NEM and WEM:77.2% peak renewable contribution in the NEMRooftop solar up 11%Wind and grid-scale solar up 16% year-on-yearRenewables supplying 36.4% of WA’s power – another Q3 recordRead the QED here: https://bit.ly/47kVBAQInterviewer: Catie LowLinkedIn | X | Facebook

From Dublin to Down Under: control rooms, transition points and the future of power system security – a chat with Yvonne Coughlan
In this first episode of our three-part series on power system security, new AEMO on Air host Nij is joined by Yvonne Coughlan, one of our Group Managers in Operations.Yvonne shares her journey from working across European power systems, including her time at Ireland’s system and market operator, EirGrid, to her work at AEMO.She reflects on the parallels and differences in global energy transitions in a conversation that explores transition point planning, what life is like inside a control room, and how AEMO is preparing for the accelerating energy transition.Interviewer: Dr Niraj (Nij) Lal LinkedIn | X | Facebook
