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 transmission 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.

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 NEM
• Rooftop solar up 11%
• Wind and grid-scale solar up 16% year-on-year
• Renewables supplying 36.4% of WA’s power – another Q3 record

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.
