Distributed generation is equipment used to generate electricity for your own use, which is connected to the Aurora Energy electricity distribution network and is capable of supplying electricity back into the network. Examples include solar photovoltaic panels, small wind turbines and mini-hydro.

Connecting distributed generation

Installing a distributed generation system is complex and no two installations are the same. We’re here to help you through the connection process. We advise you to discuss your proposal with us as early as possible.

There are different connection requirements, depending on whether the generating capacity of your system is over or under 10 kilowatts.

Small Scale Distributed Generation (10 kilowatts or less generating capacity)

Large Scale Distributed Generation (more than 10 kilowatts generating capacity)

Export Congestion

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

Technical Requirements

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

Grid tied inverters

Here are the grid-tied inverters approved for installations connected to the Aurora Energy network. Any distributed generators planning to use an inverter not listed here must provide a declaration of conformity issued by a laboratory listed on the JAS-ANZ register, attesting that the inverter complies with AS4777.2 and AS4777.3.

Commercial arrangements

You will need a connection contract between you as the electricity generator and Aurora Energy to connect distributed generation to our network.

For small scale distributed generation (≤10kW), the Electricity Authority’s Regulated Terms from the Electricity Industry Participation Code Part 6.2 will apply.

Regulated Terms from the Electricity Industry Participation Code Part 6.2

Large scale distribution generation (>10 kW) involves greater use of Aurora Energy’s system assets and requires a connection contract between us and the distributed generator. We have developed a standard distributed generation use-of-system agreement as a basis for commercial negotiations. This agreement has been developed with reference to the distributed generation regulations and appropriate conditions found in the Electricity Authority’s model contract documentation. If contract terms cannot be negotiated and agreed within 30 days (the timeframe set by Part 6 of the Code (Schedule 6.1), the Regulated Terms of connection will apply.

Small Scale Distributed Generation (10 kilowatts or less generating capacity)

Small scale distributed generation systems are typically solar panels installed on residential sites. There is no application fee for small scale applications.

Step 1: Read the following documents:

Step 2: Advise Aurora Energy via email of your connection proposal using the following form:

Small Scale Distributed Generation Connection Application (PDF)

Step 3: Aurora Energy will contact you to confirm receipt of your connection notification and, if correctly completed grant approval or advise next steps.

Step 4: Connect your distributed generation system by following the connection standards to enable generation into Aurora Energy’s network.

Step 5: Provide post-connection documentation to Aurora Energy as set out in the connection standards.

Large Scale Distributed Generation (more than 10 kilowatts generating capacity)

Larger systems are typically installed at commercial, industrial or rural sites. We have prepared a guide that covers the process requirements for connecting large-scale distributed generation. A two-stage application process is used. Both initial and final applications must be made on the 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.

Step 1: Read the following documents:

Step 2: Apply to Aurora Energy via email using the following form and send the initial application fee:

Large Scale Distributed Generation Connection Application - Initial (PDF)

Step 3: Aurora Energy will contact you to acknowledge your application and to discuss any further information or design work that is required.

Step 4: Complete the final application form and submit it to us via email:

Large Scale Distributed Generation Connection Application - Final (PDF)

Step 5: Once your final application is approved you will need to send Aurora Energy your notice to proceed in writing.

Step 6: Aurora Energy will contact you to negotiate a connection agreement to our network. Once the terms and conditions of connection are agreed you will be given approval to proceed with the connection.
