Australia’s Renewables Growth and Electricity Network Response

#renewable #energy #EVs #Australia

Australia’s renewable energy sector has been growing rapidly in the last several years.  After a brief introduction to Australia, it’s resources and electricity networks, I will then give an update of the major (GW scale) renewable projects and some other key statistics and milestones in renewables growth for 2021/22.

This growth has led to transmission network reviews and formal announcements of renewable energy zones (REZ) in NSW and Queensland. A specific example will be given: Powerlink’s Transmission network upgrade between Townsville and Cairns which supports Queensland’s Northern renewable energy zone.  Both transmission and distribution network planners are also having to decide how to manage an increasingly variable sources of generation. Options such as more storage, demand management, and generation control are all possible solutions. Planning for and enabling them quickly, and hopefully at lowest cost, is an ongoing challenge. Energex are examining MW scale batteries as a genuine mechanism for delivering distribution network capacity upgrades, and all Distribution Network Service Providers (DNSPs) are examining Dynamic Operating Envelopes (DOEs) to better manage Distributed Energy Resources (DERs). 

Finally, I will mention the (slow) growth of EVs in Australia, discuss the reasons why, and the implications as this inevitably changes.

Geoff Walker of School of Electrical Engineering and Robotics, Faculty of Engineering, Queensland University of Technology


Dr Geoff Walker joined Queensland University of Technology (QUT), Brisbane Australia, as an Associate Professor in 2013.  From 2008-2013 He was a senior electrical engineering consultant in Aurecon’s Brisbane Transmission and Distribution group, across various areas including rail traction, earthing studies, electricity transmission planning and renewable energy project design and review.

Geoff received his PhD in multilevel converter modulation from the University of Queensland (UQ) in 1999 and lectured in power electronics at UQ from 1998 to 2007. He supervised the UQ “Sunshark” solar racing team, which attracted his interest in PV, EVs and batteries which continues to this day. Geoff has also worked and maintains an active interest in the pro-audio and industrial electronics sectors.

His current research interests are applying power electronics in renewable energy,  power systems and electric vehicles (EVs).
