Application process

  • Enquiry

    The enquiry stage involves a high-level feasibility assessment, which usually determines whether there are any network impediments to the generator connecting. If there is sufficient hosting capacity we'll provide you with an application form.

  • Application

    Western Power will conduct various studies and prepare Technical Schedules for the generator.

  • Request for Approval to Operate

    Assessment of your commissioning report, updated Technical Schedules and Technical Compliance Report.

Additional information you need to know

  • 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.
  • Signing of a contract for network studies. Studies assess such aspects as network steady-state flow, protection and power quality. These studies will indicate whether any network augmentation is required.
  • If network augmentation is required, there will be additional costs for further assessment.
  • If no network augmentation is required, Western Power prepares the Technical Schedules (with customer input).
  • Following construction, the customer submits completed the Technical Schedules, a Technical Compliance Report (TCR) and a request to commission. If approved, permission to commission is granted.
  • Customer submits the commissioning results, and a request for Approval to Operate.
  • 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.
