Distributed Generation


The information contained on this page is designed to assist customers that wish to connect generation systems to the Aurora network.

Where generation will not operate connected to Aurora's network, it need only comply with the Wiring Regulations, and your electrician can advise the necessary details. However, where it will operate connected to Aurora's network, whether directly or within your installation, then safety and commercial issues arise.

Connection Requirements

Connection Requirements - Small Scale Distributed Generation

Aurora has prepared a guide that covers the process requirements for connecting small-scale distributed generation. Connection applications must be made on the form provided below.  No application fee is required.

Connection Requirements - Large Scale Distributed Generation

Aurora has prepared a guide that covers the process requirements for connecting large-scale distributed generation. A two-stage application process is used, and initial and final applications must be made on the appropriate form provided below.  Due to the greater complexity of large scale distributed generation, and the associated cost of assessing applications, an application fee is required.  Application fees vary according to the proposed generation capacity, and must accompany the application.

Grid Tied Inverters

Aurora has prepared a list of inverters that have previously been accepted for use at installation connected to the network.  As discussed in the connection guides, generators planning to use an inverter not listed must provide a declaration of conformity issued by a laboratory listed on the JAS-ANZ register (www.jas-anz.org), attesting that the inverter complies with AS4777.2 and AS4777.3.

Technical Requirements

A guide to the technical requirements that must be observed when connecting distributed generation to Aurora's network has been developed.  While this guide primarily concerns larger distributed generation connection, there are some requirements that must be observed by all distributed generators, regardless of size.

Export Congestion

There are currently no identified locations where export at 230/400V is expected to be constrained within the next 12 months.

Commercial Arrangements

As discussed in the connection requirements guide, commercial arrangements must be agreed between the Generator and Aurora. For small distributed generation, the default arrangements (regulated terms of connection) specified within Part 6 of the Electricity Industry Participation Code  (the Code) will apply. The commercial arrangements for larger generation warrants greater attention due to the greater use of system assets, and Aurora has developed a standard distributed generation use-of-system agreement as a basis for commercial negotiations. The standard agreement has been developed with reference to the distributed generation regulations and appropriate conditions found in the Electricity Authority’s model contract documentation.  Where agreement on a connection is not reached within the timeframes set by Part 6 of the Code (Schedule 6.1), the regulated terms of connection will apply.

Solar Electricity

The most common type of distributed generation system associated with domestic and small commercial installation is solar electricity, generated through photovoltaic panels.
