We’re working to deliver cleaner and sustainable renewable energy across WA’s regions
As more and more households, businesses and organisations take up solar power, we need to make sure our systems can manage higher levels of renewable energy. We’re exploring new technology and energy innovations as we work to make sure our power supply stays as stable and reliable as possible.
The impact of renewable energy
Renewable energy is a cleaner, greener way of producing electricity - but it also has an impact on our energy system as a whole.
Traditional electricity
Systems were originally built for a one-way flow of power, where electricity is generated from a central source, such as a coal-fired power station
Renewable energy
Connecting rooftop solar introduces a two-way flow of power, where solar energy systems can send excess solar energy back into the electricity grid

The impact of renewable energy
Renewable energy is a cleaner, greener way of producing electricity - but it also has an impact on our energy system as a whole.
While the South West Interconnected System (SWIS) has a greater capacity to accommodate rooftop solar, our microgrid systems are much smaller. This means our grids are more sensitive to the impact of connecting renewables. When too many renewable energy sources are connected to the grid, it can impact the stability and reliability of the network.
This is why we have a limit on how much rooftop solar can be connected to each of our grids, and why these limits change for each town.
