Due to the current economic conditions, we are experiencing a high volume of distribution grid connection and relocation applications as well as seeing the delivery timeframes for some materials items significantly extended. This has resulted in longer timeframes for products and services.

Only consultants with NER certification can apply for this service.

What to include with your application

  • A design drawing

    A geospatially correct design drawing of the subdivision plan.

  • LV Volt drop assessment

    This assesses that the voltage drop, line currents and fuse protection are adequate for each circuit. 

    Use our Low voltage design software to create an assessment.

  • Bill of materials

    The Bill of Materials must cover the materials which Western Power is to provide for the work agreed to be undertaken by Western Power.

  • Voltage fluctuation report

    A report demonstrating that the voltage fluctuation occurring at your point of supply is within limits defined in SA/SNZ TS IEC 61000.3.5:2013  “Electromagnetic compatibility (EMC) Limits - limitation of voltage fluctuations and flicker in low voltage power supply systems for equipment with a rated current greater than 75 A”.

  • Earth potential rise (EPR) assessment

    An assessment that demonstrates an earth fault on the high voltage (HV) power network does not result in dangerous levels of a earth potential rise.

  • Streetlight authorisation letter

    Streetlights within subdivision developments is provided for the local government authority (LGA). Developers will generally install either Western Power standard streetlight or Western Power’s decorative streetlight. Energy consumption on Western Power standard streetlights will be charged to LGAs as per gazetted street lighting tariffs. Energy consumption on decorative streetlights will usually be higher than the gazetted tariff.

    Therefore, Developers are required to seek the approval of LGAs if they intent to install decorative streetlights in the subdivision developments.
