Australian electricity and gas markets – April 2026 Update - Ashurst
In this update, we look at the latest rule changes and market updates published in March 2026 which affect participants in the AEGM.
www.ashurst.comI don’t have live access to the latest news feeds in this moment, so I can’t pull the very latest headlines directly. Here’s what’s currently shaping the Australian energy market landscape that’s most relevant to a May 2026 timeframe, with guidance on where to look for the freshest updates.
Key developments to watch
- AEMC rule-change activity and policy design: The Australian Energy Market Commission (AEMC) has been actively reviewing and proposing changes to strengthen reliability and price signals during the transition to more renewables. In early 2026 there was ongoing consultation around pricing reforms and market design to support consumer outcomes and incentivize investment, with draft determinations and submissions from industry bodies and consumer groups. To confirm the most recent status, check the AEMC News Centre and the latest draft determinations or final determinations posted in 2026. [Example sources: AEMC news releases and draft determinations, 2026 publications]
- South Australia Market Making Obligation (MMO) and transition measures: Several analyses and industry updates indicate SA intends to implement the MMO in July 2026, with draft legislation and design work continuing through 2026. This is part of broader market reform work connected to the National Electricity Market (NEM) improvements. For the latest on timing and legislative drafts, look for SA government releases and AEMC/Department updates around mid-2026. [Council/firm briefings cited in industry updates]
- Industry-led contract design and ISP governance: There has been anticipation of an industry-led contract co-design process, with outputs to be formalised in National Electricity Rules and the National Electricity Law over 2026. Submissions and stakeholder consultation timelines are typically published by regulators and energy market bodies. Check recent regulator calendars and joint industry statements for exact milestones.
- ISP modelling and uncertainty considerations: The debate over how the Integrated System Plan (ISP) accounts for uncertainty around emissions targets and technology costs has featured in draft determinations and submissions. The regulator has signaled flexibility in the current rules to address uncertainties, but ongoing commercial and policy analyses continue through 2026. Look for regulator reports and proponent submissions discussing ISP methodologies.
