Special Adviser

Dr Ron Ben-David served as full-time chair of the Essential Services Commission of Victoria between 2008 and mid 2019. The commission is the economic regulator of numerous sectors in Victoria including electricity and gas, water, the Port of Melbourne and local government. As a reformer, Ron led the development of an entirely new framework for the regulation of water pricing. The PREMO framework has been described as the most significant development in Australian economic regulation in many years.

Ron is continuing his passion for championing the role of customer in infrastructure through his special adviser role at Customer Stewardship Australia. He was the first regulator in Australia to recognise that a tick-the-box approach to regulatory compliance was not guaranteeing satisfactory outcomes for energy customers. This led him to develop a new ‘responsibility-based’ approach to the regulation of essential services. This has seen a new payment difficulty framework and a new family violence framework introduced in Victoria, while a broader re-write of the Victorian energy rules is now underway.

After joining the Victorian Department of Treasury and Finance in 1998, Ron held numerous senior public sector roles including as deputy secretary in the Department of Premier and Cabinet (2004-2008). During this time, he also headed the secretariat for the Garnaut Climate Change Review (2007-2008).

Ron has written and presented extensively on a wide range of topics including competition and regulation, retail energy markets, the water industry, local government, taxi reform, federalism, climate change and sustainability.

Ron holds a B.Sc (Optometry), B.Comm (Hons) and PhD (Economics) all from the University of Melbourne. He was made a Fellow of the Institute of Public Administration Australia in 2004 and became a graduate of the Australian Institute of Company Directors in 2019.
