Connecting your solar or diesel generation

A growing number of people are installing equipment at their home or business to generate power for their own use. They may also export surplus power back into our network. This equipment can include: solar panels, wind or micro-hydro turbines and diesel generators.

Information guides

We have information guides explaining what you need to do to connect your power generation equipment to our network. 

Choose the guide that is right for you: 

  • connecting your home or small business generation - 10kW or less
  • connecting your business solar generation - more than 10kW 
  • connecting your business diesel generation - more than 10kW 

Once you have decided to proceed, please complete the application form in the guide and send it to us along with your fee.

Approving your generator for connection to our network

The approval process to connect your generator is normally completed by a qualified installer. Our aim is to have your application approved within five working days.

Connecting to the Orion network requires: 

  1. A licenced electrician to complete wiring and electrical documentation.
  2. An approved inverter. An inverter is an electrical device that transfers energy from the solar panels to your house supply. The inverter has built-in electrical protection systems that keep you and electrical workers safe.
  3. Information on the size of your energy system. This allows us to manage network congestion of surplus energy.

The Electricity Authority 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. Part 6 of the Electricity Authority Code, Connection of Distributed Generation, was updated in February 2015.

The Electricity Authority website also provides a glossary of common industry terms.
