Distributed generation

Installing distributed generation and connecting it to EA Networks’ electricity network

Distributed generators (DG) is one of a number of different terms used in the electricity sector to describe private generation sources. At the earliest possible stage of your distributed generation project, we recommend that you obtain a copy of our Network Connection Application. We also recommend that you obtain expert technical advice on how to correctly install, connect and operate your distributed generation system.

Please see below for further information based on your generator size:

Distributed Generation - 10 kilowatts or less
Distributed Generation - above 10 kilowatts
 
To obtain a paper copy of this documentation, please contact us 0800 430 460. After receiving your application, EA Networks will start an approval process as outlined in Part 6 of the Electricity Industry Participation Code.

Statutory, regulatory and safety requirements

If you connect distributed generation to our network, safety equipment and procedures must be put in place to ensure safe interaction between your distributed generator and our network. At times, your distributed generator may be interrupted to comply with our own operation standards.

Familiarise yourself with the following documents:

EA Networks Use of System Agreement

New Zealand Standard AS/NZS 3000 – Electrical Installations (known as the Australian/New Zealand Wiring Rules), which you can purchase and download from WorkSafe NZ’s Energy Safety website.

New Zealand Standard AS 4777 which provides standards for connecting inverter-based systems and is a useful guide for installing other forms of generation. You can purchase and download from Standards Australia.

The regulated terms of your distributed generation connection, as defined in Schedule 6.2 by the Electricity Authority in the Code.

The Electricity Authority also provides information on the rights and responsibilities of a person or organisation wanting to connect a distributed generation system to an electricity network and the network provider.

Network Export Congestion

There are no areas across EA Networks' low voltage network where generation export congestion is, or expected to be, an issue within the next year.
