Embedded generation

Generators that are connected to the distribution network and do not have direct access to the transmission network are known as Embedded Generators or Distributed Generators.

Embedded Generators that are connected to our network vary in type and size. Most are solar photo-voltaic (PV) generators connected within the premises of our residential customers and are typically less than 10 kW in size. Others are co-generation plants, tri-generation plants, diesel units or large scale solar photo-voltaic (PV) generators ranging from 30 kW to less than a few megawatts in size and support our commercial and industrial customers. A few embedded generator connections in our network are larger than five megawatts and they sell electricity generated directly to a single large consumer or into the National Electricity Market.

Before you connect or alter solar, batteries or any other generation system at your home or business, it’s important that you let us know so we can ensure the connection is safe.

We classify Embedded Generators into the following categories:

Micro-embedded generators

Inverter connected generators (usually solar) less than 10 kVA for a single phase connection or less than 30 kVA for a three phase connection. These generators connect to the low voltage (230 V single phase or 400 V three phase) network.

  1. Contact a registered solar panels provider to organise panel installation. You can find an installer through the Clean Energy Council.
  2. Complete an application form. Once we receive it, we’ll make the changes we need to your electricity meter.

You’ll find all documents relating to micro embedded generators in our document centre.

If you need any other information to help with your micro-embedded generator connection, please email us.

Mid-scale embedded generators

Less than 5 MW in size and of the type that cannot be classified as micro-embedded generators. These usually connect to the low voltage (230 V single phase or 400 V three phase) or high voltage (less than 22 kV) network.

You’ll find all documents relating to mid-scale embedded generators in our document centre.

Large embedded generators

Greater than 5 MW in size and connect either to the high voltage (less than 22 kV) or sub-transmission (less than 66 kV) network.

You’ll find all documents relating to large embedded generators in our document centre.

If you need any other information to help with your mid-scale or large embedded generator connection, please email us.

New solar inverter guidelines

Customers who are planning to purchase new inverters should note the 2015 edition of the installation standard - AS/NZS 4777.2 Grid Connection of energy systems via inverters – Inverter requirements will apply from 10 October 2016.

This means that only inverters compliant with the 2015 edition of the Standard can be connected to electricity networks from 10 October.

To check that your inverter is compliant with the new standard, go to the Clean Energy Council list of approved inverters at: http://www.solaraccreditation.com.au/products/inverters/approved-inverters.html
