A former chair of Australia’s National Electricity Market review has called for decisive industry action as the country accelerates its transition from traditional fuel storage to a system increasingly reliant on energy storage technologies.

The shift reflects a broader transformation of Australia’s energy landscape, where renewable generation such as wind and solar is rapidly replacing fossil fuels.

Unlike coal and gas, which can be stockpiled as physical fuel, renewable energy requires storage solutions such as batteries and pumped hydro to ensure reliability when generation fluctuates.

The former review leader has emphasized that this transition demands a fundamental rethink of how energy security is managed.

Instead of maintaining reserves of fuel, the focus must move toward ensuring sufficient storage capacity and grid flexibility to meet demand during periods of low generation.

Industry stakeholders have been urged to act more quickly in deploying large-scale storage infrastructure, integrating distributed energy resources, and improving coordination across the electricity system.

Without timely investment and planning, there is a risk that supply gaps could emerge during peak demand or extended periods of low renewable output.

The warning comes as Australia continues to retire aging coal-fired power stations and increase its reliance on renewable sources.

While this transition is expected to deliver long-term benefits in terms of emissions reduction and energy costs, it also introduces new operational challenges that require advanced planning and technological innovation.

Energy storage is increasingly seen as the cornerstone of the future grid, with projects involving grid-scale batteries and pumped hydro already underway across multiple states.

These systems are designed to store excess electricity when supply is high and release it when needed, helping to stabilize the network and maintain reliability.

The call for action also highlights the importance of clear policy signals and market frameworks that support investment in storage technologies.

Ensuring that regulatory settings keep pace with technological change will be critical to unlocking private sector participation and accelerating deployment.

As Australia continues its energy transition, the focus is shifting from simply generating power to managing when and how it is stored and delivered, marking a significant evolution in the structure of the electricity market.
