About
The second seminar in our MEI Seminar Series for 2025 was presented by Mr Matthew Clemow, Group Manager Gas Market and System Operations, Australian Energy Market Operator (AEMO).
The presentation provided an overview of AEMO’s gas role and functions within Australia’s East Coast Gas System including the energy market regulatory framework and how the gas markets balance supply and demand. It also covered the drivers for the gas supply shortfalls forecasted from winter 2028.
There are different gas market designs and supply mechanisms to meet the supply objectives of that market. AEMO’s largest gas market is in Victoria, where AEMO has the unique role of operating both the Victorian gas transmission system and the wholesale gas market.
AEMO has been responsible for managing gas supply adequacy for the East Coast Gas System since May 2023 following the gas supply challenges during winter 2022. Further reforms to increase AEMO’s role are being developed to respond to the forecast gas supply shortfalls.

Moderator
Dr Sleiman Mhanna
Senior Research Fellow, Integrated Energy Systems
Department of Electrical and Electronic Engineering, Faculty of Engineering and IT
The University of Melbourne
Dr Sleiman Mhanna received his PhD in electrical engineering from the University of Sydney in 2016 with emphasis on fast distributed methods in power systems and demand response pricing mechanisms. For the subsequent three years he was a research fellow at the same institution, working mainly on the award-winning CONSORT project funded by ARENA, where he developed fast distributed optimisation methods and nonlinear pricing structures for load-side distribution network support.
He is currently working on designing mathematical models and scalable algorithms for the operation and planning of integrated electricity, gas and hydrogen systems. The studies he has conducted over the past three years, which include electrification of residential heating demand and modelling of hydrogen blending in gas transmission networks, are currently used by Future Fuels Cooperative Research Centre (FF CRC) and its industry partners in their policy initiatives and decarbonisation roadmaps.
About MEI's Seminar Series - a deep dive into the energy supply chain
The aim of MEI's Seminar Series is to give participants a sound understanding of the current technical and economic factors that underpin the Australian energy system. Knowledge of these market factors is critical in determining the changes required to move towards a clean energy system.
Each year, the focus is turned to one of our primary energy vectors, cycling through the major topics of electricity, natural gas, and energy commodities.
In 2025, the focus is once again turned to the gas supply chain. The seminars are delivered by specialists from industry and the University of Melbourne. Read more about the seminars, and sign up to be notified when the seminars are open for registration.
