Getting Connected

If you are building a new property, planning a dairy farm conversion, shifting a building and need it reconnected, demolishing a building, or upgrading your existing supply, you will need to make arrangements to connect to – or disconnect from – the PowerNet network.

If you are moving into an existing property and want to get the power turned on, please contact an electricity retailer to arrange supply. Click here for a list of the electricity retailers connected to our networks.  A PDF version of our Connections brochure can be found here (this is a guide, not the connections form. The link to the application form is below).

Getting connected

Prior to connecting any property to our electricity network we must be satisfied that the connection can be made safely without adversely affecting the delivery of electricity to other customers connected to the network. PowerNet must ensure that sufficient capacity exists to accommodate the increased load of the new connection and that the electrical configuration is suitable.

Before you can be connected to our network we need:

  • An Online Installation Connection Application that has been signed and accurately completed.
  • For large connections i.e. greater than 100 kVA, a capacity guarantee which has been accurately completed and signed may be required (this is generally only for non-residential applications)

Using an Independent Contractor

It is possible for a consumer to use an independent contractor to design and build part of their new connection.   If you are developing a new subdivision or if your new supply is large or remote from the existing network and will require our high voltage network extending across private land you can use an Independent Contractor to carry out some of the work.  Further information is available in our Independent Contractor and Developer Reticulation in Subdivisions documents.  Please note that there are some statutory tasks that only PowerNet can perform.

Connection application

An Online Installation Connection Application must be completed for all new connections, alterations and temporary connections.

We appreciate as much prior notice as possible to help us meet your timing requirements.

To ensure that your request is processed and approved as quickly as possible, the online application must be filled in completely, dated and submitted.

Your application form must include:

  • Your name and contact details.
  • The address of the connection.
  • The number of phases you require (one, two or three).
  • The capacity needed at the site (e.g. 60 or 100 amps).
  • The description of work being carried out.
  • The connection use (e.g. residential, factory, dairy farm).
  • Sketch of the physical location of the connection with as much accurate site information as possible (e.g. closest pole number) to help us verify the exact location of the connection in relation to our existing network.

You are welcome to contact our Connection Team to talk about the application, phone 03 211 1899 or email us on

Electricity retailer

You need to decide who your electricity retailer will be and include this information on the application. PowerNet has an agreement with specific electricity retailers which allows them to deliver and sell electricity to you via our network.

Please be aware that the connection application form is not an application for the supply of electricity into the property – this must be organised by you through an electricity retailer.

Capacity guarantee

Some customers have sufficient demand i.e. greater than 100 kVA, to require a capacity guarantee. After we have determined your specific requirements we will prepare an agreement outlining the legal requirements. To find out more about pricing schedules and capacity guarantee terms and conditions phone PowerNet on 03 211 1899 or email

Connection application process

  • The network line that will supply electricity to the new connection is checked to ensure that it can accommodate the additional load and that the additional load will not adversely affect other customers connected to the existing network.
  • Sometimes we find that additional work can be required to upgrade the existing network to accommodate the new connection.  This increases costs and takes some time to complete. To avoid possible time delays and surprises about cost please talk to us at the very early stages of your planning.
  • We calculate any charges to you and advise you by letter, then await your agreement. PowerNet contributes some costs towards the connection. Contact PowerNet staff for more information about the PowerNet contribution.
  • PowerNet manages electricity networks throughout Southland and in some areas of Otago on behalf of network owners. The network owners are:
    • Electricity Invercargill which is owned by the Invercargill City Council and covers most of Invercargill City and the Bluff township.
    • The Power Company which is owned by everyone connected to the network through a Trust known as the Southland Electric Power Supply Consumer Trust, and covers Southland, excluding most of Invercargill City and Bluff.
    • Otago Joint Venture which is jointly owned by Electricity Invercargill, The Power Company and Marlborough Lines, and covers North, South and East Otago.
    • Lakeland Network which is an embedded electricity network in Frankton that is owned by Electricity Southland.
    • Stewart Island Electricity Supply Authority which is owned by the Southland District Council.
  • We advise you which network you will be connected to and issue you with a unique installation connection point number (ICP number) and advise your chosen electricity retailer. Click on this link for more information about ICP numbers.
  • Your chosen retailer confirms that they will supply electricity to you. Your installation can only become active once an electricity retailer has approved your request.
  • PowerNet will complete the required work following confirmation by your electricity retailer.
  • Your electricity retailer will arrange installation of the meter.
  • The power connection is livened when the metering is installed, all PowerNet’s network requirements have been complied with, and when the service main and the electrical compliance certificate has been completed.

If you are building you may also require a temporary supply connection. Refer to the temporary supply connection link for more information.

If you want to connect a distributed generator to our network, please refer to the link on distributed generation.

If you are demolishing or relocating a building please refer to the link on disconnections and reconnections.
