Distributed Generation

If you are wishing to install a Distributed Generation system, e.g. solar panels, you will need to get in contact with an installer and have them apply on your behalf. 

What happens after the installer has applied?

We will assess the impact your generation will have on our network. If the load you wish to generate exceeds what is supported by the transformer at your gate, adjustments may need to be made to your application. In this case, we will notify your installer.

If there are no issues, we will advise you your application has been accepted. Once approved, your installer can install and test your system. It is important to note that your application will not be approved if the inverter does not comply with the legal requirements under AS/NZS 4777.2:2020. A list of approved inverters can be found here.

Once the installation is complete, we will require a copy of the Certificate of Compliance and Commissioning Declaration to verify the system complies with the Electricity (Safety) Regulations 2010.

Extra Note: The Electricity Industry Participation Code requires all generation installations to have metering which separately records imported and exported energy. Discuss this with your contractor and if metering upgrade is required, please contact your energy retailer.

Once submitted, how long until I am notified of the application outcome?

  • Within 10 working days if submitted under Part 1 of the Electricity Industry Participation Code;
  • Within 2 working days if under Part 1A.

Discuss with your installer which section is applicable to your application or refer to the link below for more information:

Electricity Industry Participation Code Part 6

Is there an application fee?

  • For distributed generation systems up to 10kW total capacity:No application fee (most systems installed at residential properties will likely be below 10kW).
  • For distributed generation systems above 10kW total capacity:These larger systems require a more detailed technical investigation into their effect on the network and are therefore subject to the regulated application fees detailed here.

Why do I need to apply with Powerco to install my system?

Powerco must know the location and capacity of all connected generation to be able to ensure the safety of staff, contractors and the public.
