Network Information - Shire of Irwin


The data presented here (customer numbers, distribution network overhead circuit length, distribution network underground circuit length, as well as the number of distribution network poles) in those local government areas (LGAs) that Western Power fully or partially supplies electricity to.

This data does not include customers or assets from other electricity network suppliers that may also service these LGAs (such as Horizon Power). Circuit Lengths are an estimation for each Local Government Area and do not include those circuits that are exclusively designated for street-light supply.

This data is as of 8 November 2022 and as a consequence, cannot be compared to other similar information either published externally or circulated internally within Western Power.

Reliability information

This includes all unplanned interruptions (excludes planned interruptions and interruptions lasting one minute or less). The reliability data includes delays to restoration due to bushfire settings.

Ring Main Units (RMUs) upgrades

At the beginning of June, we completed upgrades on the Ring Main Units (RMUs) in the Shire of Irwin. The RMUs were replaced with more advanced technology at:

  • Golf Course Road, Port Denison
  • Pearse Road, Port Denison
  • Tyford Road, Dongara

The advanced technology will enable automatic fault detection and remote switching capability. This will support a faster response to power outages. Watch the video that explains more about the upgrades.
