What will I need to complete this application?

How much will it cost?

The cost of an electricity supply is dependent on how much power you require:

Size of your desired supply Cost range

14.1kVA (3 group lots / dwellings) – 31kVA (10 group lots / dwellings)

$7,000 - $15,400

31kVA (10 group lots / dwellings) – 62kVA (20 group lots / dwellings)

$15,400 – $30,800

In most cases, the cost will be based on the Distribution Low Voltage Charges Headworks Scheme.

What more do I need to know?

  • Your point of connection to the electricity network will either be single phase or three phase, depending on the surrounding network.
  • Wherever possible we will provide an underground connection via a green dome.
  • There are some physical clearances that are required between the electricity network and your equipment. You can find information about them here. If your property will have multiple points of supply, compliance information from the West Australian Electrical Requirements can be found here. In some cases non-compliant points of supply might still be viable - if you would like to pursue this, consider a feasibility study.
  • You will need an electrical contractor to install your meter and terminate your consumer mains.
  • If your consumer mains are larger than 35mm2, we will need to terminate them for you instead.

Substation site

  • Depending on your supply requirements you may need to provide space for a substation site. We will notify you if this is the case. If you are unsure about where a substation site can go please submit a feasibility study and one of our consultant engineers will help you you in find a solution.
  • When making decisions about a substation site, please read the Western Power Distribution Substation Manual.
  • If you would like to apply for a non-compliant site please submit a feasibility study and one of our consultant engineers will let you know if it can be used.
  • Sometimes we have to change substation specifications or location, if this is the case we will let you know.
  • If your supply will be greater than 100A your electrical contractor will provide the appropriate sized current transformers.

What if I change my mind or want to cancel my application?

Sometimes your circumstances change and you may need to cancel or change the information within your application after you have submitted it to us.

If you wish to change the scope of work in your application we will first review the change and then either:

  • continue the project with the variation and invoice you for any additional materials, design work and remobilisation costs incurred. We will typically only take this approach when the change is very minor.

    or

  • if the change is significant we will cancel your project. You will need to submit a new application with your new requirements.

For cancelled applications we will invoice you for the costs incurred up to the point of cancellation (time and materials). If construction work has already commenced we will refund the difference from your access offer less any costs incurred.

Fees and charges

Following the cancellation, expiry, termination or variation of the Customer Work Request or any other aspect of the works or documentation relating to the works, the customer may be liable to pay an administration fee of $550 (inclusive of GST) and any additional costs incurred by Western Power.  Further information can be found in our Terms and Conditions clauses 8 and 16.3.
