ANU Solar Oration 2025: Merryn York

The electricity system we rely on today has been developed over decades, delivering reliable power to homes and businesses and underpinning modern life. As we move toward a net zero future by 2050, this highly complex system is undergoing a profound transformation.

While significant progress has already been made, the journey is far from over. The electricity sector—often viewed as one of the more straightforward to decarbonise—is now being called upon to do even more. Beyond its own transition, it is expected to support the decarbonisation of other sectors such as gas and transport through widespread electrification.

Maintaining the stability and reliability of the system while integrating large-scale renewable resources like solar and wind is a critical engineering challenge. At the 2025 Solar Oration, Merryn York AM, a distinguished electrical engineer with extensive experience across the energy sector, will explore the complexities of this transformation and share insights into how it might be achieved.

An opening statement on the ACT's progress towards net zero emissions will be delivered by Suzanne Orr, Minister for Climate Change, Environment, Energy and Water.

Professor Andrew Blakers AO from the ANU College of Systems and Society will present an annual engineering student thesis award.

Please note that this is a hybrid event. Participants can attend in person at the Australian National University Acton campus or online via Zoom.

Light refreshments will be available for in-person participants between 5:30 and 6pm. The event will commence from 6pm.
