The cost of an electricity supply is dependent on how much power you require. In most cases, the cost will be based on what we call the Distribution Low Voltage Connection Scheme.



The type of connection provided will depend on the location - most customers will receive an underground connection, however in some regional areas where the traditional network had been identified for decommissioning, customers may be eligible for a stand-alone power system.

Application process

You’ve applied

We’ll contact you to discuss your application.

You’ll receive a scope

After our technical assessment we’ll confirm the scope of works with you.

You’ll receive design fee invoice

Once payment is received, we will design the project to your needs.

You’ll receive a quote for the delivery of the works

After the acceptance and payment is received, we’ll schedule the works for delivery. Schedules are dependent on your location and the complexity of our work.

Let us know how we went

Your feedback is importance to help ensure we’re meeting your needs and expectations.

The services of a National Engineering Register (NER) engineer will be required to advise in general on the process to be followed, the system design, and the equipment to use.

The site’s electrical retailer is required to submit an ETAF (Electricity Transfer Application Form) to Western Power and a service request to change the site’s meter to bi-directional (required regardless of whether the generator is exporting or not). These must be completed before an Approval to Operate can be released.

What to include with your application

circle check orange

A CAD site plan

Your CAD plan helps us better understand your work site and location of assets. We extract data from your plan to assist us with your design.

Site plan for a small commercial connection

For a CAD site plan to be accepted, it must clearly show:

  • the proposed pillar location in a visible colour on the site plan.
  • the street name on which the property borders.
  • the full address of the property.
  • the nearest intersection (for rural properties it helps to locate the site)


In order to provide a fast, accurate quote and advice on your new connection arrangement we require a comprehensive site plan with details of your current and/or proposed site layout. This includes but is not limited to the following information being clearly marked on your plan:

  • boundary or retaining walls at the side and front of the property - including depth of wall
  • location of items such as letterboxes, garden beds, trees/stumps, driveways, crossovers
  • detail or grades of any major inclines or slopes near the front boundary
  • utility locations for water meters/pipes, gas pipes, sewer mains/connections and access points
  • proposed location of new pillar/s


Example site plan


Pillar exclusion zone

The pillar needs to have an exclusion zone of 50cm from its centre. Inside or under the exclusion zone there must not be any:

  • water pipes, water storage facilities or water meters
  • gas pipes or meters
  • telecommunication cables
  • sewage, waste water, or storm water pipes
  • reticulation pipes or cables
  • tree roots and other vegetation
  • concrete, asphalt, limestone or bedrock


Find out what underground assets may be in the vicinity by submitting a Dial Before You Dig application.

Site photos

Help us understand your current connection arrangements and more easily identify potential site-specific issues. Photos will need to include:

  • The extent of the worksite
  • Any obstructions in the area

Site photos for a small commercial connection

Site photos help us understand your current connection arrangements and more easily identify potential site specific issues. If you're able to supply us with a close up and wide photos it will potentially reduce application times as we won't be required to visit the site.

Neighbours authority

If your project will impact your neighbour’s property by having new assets installed or relocated on or in front of their property, you’ll need their authorisation.
