Connecting transmission loads and large generators

  • Enquiry

    The enquiry phase provides guidance on the information required to complete a connection application form. An enquiry assessment will help you to identify a suitable network connection point and evaluate the feasibility of your project. Submit an Enquiry Notification Form to network.access@westernpower.com.au.

  • Project initiation

    We identify network constraints applicable to your application, assess if your application is competing for network capacity, and identify viable options to modify the network to meet your requirements.

    After your initial enquiry you will be required to complete the transmission loads and generators in excess of 30 kVA application form.

    Please note that we can only accept the submission of externally hosted files through Microsoft OneDrive. More information about embedded generator connections (30 kVA to 150 kVA in size).

  • Project scoping

    We develop a scope of work for each option to modify the network, assess each option, and select the final technical solution to be implemented.

  • Project planning

    We prepare business cases, contracts, detailed designs and estimates, and construction plans for the final technical solution to modify the network.

  • Construction & commissioning

    We construct and commission the required network modifications under the terms of the Interconnection Works Contract (IWC).

  • Operation

    Once constructed, the new or modified connection assets become the property of Western Power. Assets can now begin operating under the terms of the Electricity Transfer Access Contract (ETAC).
