Submitting an application

Submitting an application

Type your email into the mandatory field and press "send now". This will retrieve your application.

Click ‘save for later’ at the top of the application. This takes you to screen where you can email yourself a link to retrieve the application. If you do not do this, you will need to start again.

Check the file size and the type of file.

If you are still having problems, contact us online with the project reference number, attaching the document and explaining that you had trouble with the upload.

For small residential connections, submit an application to increase your power supply. You may have to go underground depending on the project scope.

Your application will be assessed by a designer who will then get in touch with you.

You will be charged a design fee upon lodging your application.

Once your project proceeds to construction phase the design fee, excluding GST, is deducted from the price on your Access Offer and Acceptance.

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.


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

The bill of materials is a TXT file based on the DDC manual created from Microstation or DQM CU EXPORT FACILITY and generated by the DQM/CAD Interface. Your bill of materials is to be provided for Design Conformance Review in accordance with Underground Distribution Schemes Manual Section 4.4.4.

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. See example here

A civil National Engineering Register (NER) certification verifies that the substation retaining walls are structurally sound and/or battered slopes are suitable for their purpose. This certification must be provided in accordance with the Underground Distribution Schemes Manual Section 5.3.18.

A concept plan provides us with a view of the subdivision, the scale of the project and nature of the proposed electrical network. Together with stage timing information, we can undertake planning assessments and produce a Design Information Package(DIP). See example of HV concept plan.

Design drawings are provided for Design Conformance Review in accordance with Underground Distribution Schemes Manual Section 4.4.4. The drawings must be geospatially correct by incorporation of Map Grid of Australia MGA94 grid system. Other design drawing requirements are in Appendix 4 of the Underground Distribution Schemes Manual.

The information allows us to check the impact of your loads on the network.  You must comply with Power Quality limits as per AS/NZS 61000.3.11, SA-SNZ TR IEC 61000.3.14 and Western Power Technical Rules.

A site plan provides us with an understanding of your work site, the location of existing and new assets and help us to design your product.

You must have authorisation from your neighbour if your project will impact their property.

Site photos help us understand your current connection arrangements and more easily identify potential site specific issues.
