Network testing to support a clean energy future

HomeNetwork testing to support a clean energy future

As more households and businesses invest in new energy technologies such as solar and batteries, we are building our capability to support a clean energy future and the rise in electrification across the sector.

Over the next few weeks, we are testing how we manage voltages on our network.

Growth in rooftop solar systems and other distributed energy resources can create challenges for networks as they can push up voltage levels in the system.

Managing voltage on our network is important to enable more solar, reduce carbon emissions and keep power affordable for all our customers.

These tests will help us to define operational settings on our network to ensure power remains safe and reliable as more renewable energy comes into the system.

What does it mean for you?

CitiPower will be conducting voltage tests on our network in August, but you are unlikely to see any changes to your power supply.

Testing will run for up to 45 minutes. We will not be turning power off to customers in connection with this testing.

While it is highly unlikely you will notice any changes to your power during testing, in rare cases, some customers may experience their solar system or other sensitive equipment tripping. Should you experience any irregularities to your supply resulting in financial loss, please submit a claim online at

If you have any questions, please contact CitiPower on our general inquiries line –1300 301 101.

What are voltages?

Voltage is the technical term for the pressure that pushes electricity through our powerlines. Voltage is measured by volts and higher voltages cause more electricity to flow.

Networks like CitiPower are required to deliver electricity to homes and businesses within a range of 216 and 253 volts. CitiPower uses a system to manage voltage fluctuations on the network in real time.

If the voltage is too high, customers may use more power than necessary, and it can potentially damage some appliances. If voltage is too low, customers may experience flickering lights and generally poor power quality.
