Perhaps you've bought a brand-new piece of equipment that needs more power than you currently have, or you've moved premises and the power needs upgrading to suit your business needs. If you're a small or medium business looking to modify your current supply, you can find everything you need to know including information relating to underground power, administrative costs and any other fees and charges included.

What to include with your application

  • 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 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
  • Single line diagram

    The single line diagram provides us with the technical information to design a connection to meet your requirements.

  • Load breakdown

    Your load breakdown allows us to assess the impact your project will have on the network. It also allows us to apply the appropriate charging policy.

  • Disturbing loads

    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.

Additional information you need to know

If your application is in relation to subdividing your land, there are a few conditions you need to meet before you can request clearance from the Western Australian Planning Commission (WAPC) or complete your built strata development. If we have asked you to apply for a new connection in order to meet our condition(s), it’s handy for us to know if it’s linked to a subdivision so we can collate all the right information to ensure the right checks and balances are undertaken.
