In Transition: Transmission
Insight into a changing energy system
Australia's grid is the vast, connected network of wires, towers and substations that delivers electricity to our homes and businesses.
It was built for coal. Connection points were next to the coal fired power stations. Wires ran one way into the cities.
Today, much of the ageing coal fleet is getting ready to be retired. Increasingly our power comes from renewable sources like wind and solar. It’s generated from projects across the country and often stored in batteries connecting to the grid at different points.
Transmission is not simply an engineering asset. It changes the way the entire power system operates. Just as highways connect cities and create economic opportunities, transmission connects energy resources and consumers across regions.
Australia needs an energy system that can meet our demand while lowering emissions. The electricity grid and transmission networks require significant investment to connect renewable energy resources, improve resilience, maintain reliability and support Australia's growing electricity demand.
Follow In Transition for more insights into a changing energy system.
The future runs on many.
Wire ran one way into cities. And every state or territory ran its own grid.
Renewable sources provide over 40% of energy generated and connect the grid at different points across the country.
We need a grid that can connect them and keep supply stable.
Batteries and firming capacity smooth the gap between sunshine and demand.
Is how Australia keeps the lights on through the transition.
