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).

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.

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.
