Western Power is making a substantial investment of over $3.0 million for the benefit of Nannup residents. The upgrade will involve replacing one Ring Main Unit (RMU), approximately 280 poles and 35kms of High Voltage lines, along with other essential network maintenance activities. 

Most of the work will be focussed on the main powerline between Nannup and Yornup. The RMU replacement is in Nannup townsite. This upgrade will help strengthen network resilience against seasonal and environmental impacts and enhance safety. 

Planned network upgrades

  • Wood pole replacement
  • Overhead wire replacement
  • Other maintenance works  

Project timeline

Stage 1 - December 7, 2023

One RMU and around 30 poles will be replaced during stage one. A planned outage is required on the day affecting Nannup townsite and surrounds.

Stage 2 - December 2023 to mid-February 2024

Approx 250 poles will be replaced by our crews using glove and barrier approach to allow the work to be completed while the line is live. No outages are required. Work is to be carried out on the feeder line from Yornup to East Nannup. 

This work may impact a small number of landowners with plant and equipment accessing their properties. We will contact landowners if property access is required. 

Stage 3 - February to May 2024

(Overall works and timelines are subject to change for critical reasons including network emergencies, weather conditions, faults, technical reasons etc)

How this work may affect you

It’s important to know that we sometimes need to schedule power outages in order to ensure safety of residents and crews. You’ll receive notification of any required outage in advance. Please check your notification carefully as you may receive more than one due to multiple outages.   

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. 

  • 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.  
  • While work is being completed you may notice more heavy vehicles in your area. Traffic management will be in place if required.  
  • Our teams will notify if access is needed to an individual’s property. 

We are working closely with the Shire of Nannup 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.
