Network testing May 2024

As more households and businesses invest in solar and batteries, we need to build our capability to support a clean energy future and increasing electrification across our communities.

In May 2024, we’re testing how we manage voltages across the network to accommodate for these capabilities.


Why are we testing the network?

Growth in new energy technologies, such as rooftop solar systems and batteries, create challenges for our electricity network as they can raise voltage levels across the system.

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

Regular testing helps us to define operational settings on our network to ensure power remains safe and reliable as more renewable energy is connected to the network.


What does it mean for you?

We will be conducting voltage tests across the network in May 2024.

Testing will run for up to 60 minutes. We will not be turning your power off as part of this testing, and you’re unlikely to notice any change to your power supply.

In rare cases, some customers may experience their rooftop solar system or other sensitive equipment tripping. Should you experience any irregularities to your supply resulting in financial loss or damage to appliances, please submit a claim.

If you have any questions, please contact us on 13 22 06.

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 and Powercor are required to deliver electricity to homes and businesses within a range of 216 and 253 volts. We use a system to manage voltage fluctuations on the networks 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 poor power quality.
