Nannup network upgrade

Western Power is making a substantial investment of over $3 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  

Please refer to the map below for an overview of the work areas.

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. 

Work is underway to replace the 280 poles and 35km of overhead powerlines in the Nannup area. We are thankful for the patience of the local community while we complete this work. 

We have deployed a high voltage injection unit (HVIU) generator to provide support to homes and businesses in the Nannup townsite during this maintenance period.

We ask all local residents to be aware that during this time, intermittent power outages may be experienced as we carry out the necessary work. Residents connected to the generator may experience brief interruptions, typically occurring once in the morning and once in the evening, with each lasting up to 30 minutes.

There may be some instances where longer outages will be required, particularly when maintenance work is being carried out on a power line, as this cannot be supported by the generator. We’ll provide affected residents with notice if an outage like this is required.

While the HVIU will support the Nannup townsite, it has limited capacity and may trip off if overloaded. Where possible, we ask residents and businesses to help manage the load when the generator is running by reducing your energy use. Ways to help reduce your use include:

• limiting the use of major appliances (washing machines, dryers, and dishwashers) between 5pm and 9pm
• using pool pumps during the middle of the day
• setting air conditioners to 24 degrees in hot weather and 20 degrees in cooler weather
• turning off appliances at the wall, as they still use power on standby
• for properties with solar power, setting timers to run appliances in the middle of the day to get the most from the sun.

Please be aware that some customers who cannot be connected to the generator will experience full day outages.

Affected residents will receive notification sof any planned outages in advance. We urge the Nannup community to check notifications carefully as properties may experience more than one outage.

Please note that the overall work and timelines are subject to change, for reasons such as network emergencies, weather conditions, faults, or technical issues. 

We appreciate your patience as we work to ensure the continued reliability of electricity supply in your area and a better and more resilient network for the community.
