Western Power has been working with the Shire of Augusta-Margaret River to plan an upgrade to the feeder line between Karridale and Augusta in late 2023 to early 2024. The upgrade is focused on improving network reliability, maintaining high standards of safety and enhancing network resilience to major weather events.  

We’ll be replacing approximately 70 poles, 12km of overhead power lines, upgrading insulators and crossarms, and carrying out other essential maintenance within the area.

How this work may affect you

It’s important to know that we need to schedule power outages to do the work safely. You’ll receive notification of any required outage in advance. Please check your notification carefully as you may experience more than one outage.    

A temporary large-scale generator will be deployed to support homes and businesses. We’ll need to de-energise the line on 19 November 2023 to install the generator. Residents in Augusta, Karridale, Kudardup, Molloy Island and surrounds will experience an outage from 6am to 4pm.  

After the generator is installed, these residents will experience short outages (one in the morning and one in the evening – up to 30 minutes). Some customers will experience full outages when work is happening on their side of the network.  

  • Customers will be notified a minimum of three business days (but typically up to 9 business days) prior to an outage that interrupts power supply. These notifications are sent to the primary account holder only. Please forward to anyone else who may be impacted by the planned outage, i.e. tenants. 
  • While work is being completed you may notice more heavy vehicles in your area. Traffic management will be used where needed and we’ll contact you if we need to access your property.  
  • Our teams will notify if access is needed to an individual’s property. 

We are working closely with the Shire of Augusta-Margaret River to keep disruptions to a minimum.  

We understand that the planned work may cause some short-term inconvenience, but we expect that these upgrades will bring improvements to reliability of power supply to the town.
