Gas-fired power provides firm, dispatchable energy—meaning it can be turned on or ramped up quickly when demand spikes or when renewable sources like wind and solar aren’t generating (e.g., at night or during calm, cloudy weather). This helps maintain grid reliability during the transition period when renewables and storage are still scaling up.
While renewables are growing rapidly, they are variable by nature. Gas is a flexible “partner” to renewables—it can fill gaps in generation and balance solar and wind energy.
As ageing coal-fired power stations retire, Australia needs replacement capacity to keep the lights on. Gas can serve as a transitional solution while renewableenabling technologies like batteries, and pumped hydro mature and scale.
Industrial processes and peak electricity demand (such as hot summer evenings) often require power that is both firm and scalable. Gas-fired plants can meet these needs without long lead times or massive infrastructure upgrades.
Gas provides critical backup during grid emergencies, extreme weather events, or unexpected outages—making it an important insurance policy for a stable, reliable energy system.

We think batteries would be better than gas to provide stored energy from renewables
We need more time and opportunities to understand the project
You have taken a long-time to develop the project and we are not sure it will go ahead
We would like to understand what we will see in the landscape, particularly the height of the stacks
Fresh air is important to us as a rural community, and we need to know how a power station manages air quality.
Our rural community is peaceful, and we need to see noise modelling for construction and operations.
Construction would need reliable roads and create a lot of truck movements – we would like to understand safety, maintenance and road upgrades required.
Our community is growing fast, and housing is a challenge. We need assurance that the workforce won’t impact rent or motel availability.
We enjoy the wildlife and the Wollondilly River and need to understand how these would be protected and how any impacts would be managed.
Energy Australia acknowledges that the site of the proposed Marulan Gas Fired Power Station project is on the traditional Country of the Gandangara People. We recognise their continued connection to land, waterways and community, and we pay our respects to Elders past and present.
