Supply reliability targets
Our reliability targets are listed below. These targets are updated annually.
| 1 July 2023 – 30 June 2024 (FY24) | Urban feeder | Short rural feeder | Long rural feeder |
|---|---|---|---|
| Average minutes off supply per customer (unplanned power outages) | 87 mins | 195 mins | 294 mins |
| Average number of supply interruptions per customer longer than 3 minutes (unplanned power outages) | 0.89 | 2.01 | 2.63 |
| Average duration of an unplanned customer interruption + | 98 mins | 97 mins | 112 mins |
| Average number of momentary interruptions per customer less than 3 minutes (unplanned power outages) | 2.82 | 5.66 | 9.92 |
| Average minutes off supply per customer (planned power outages) * | 95 mins | 162 mins | 236 mins |
+ Derived based on USAIDI and USAIFI targets.
* No AER targets. Internal only based on FY19-FY23 (5 year) weighted average.
We estimate that approximately 45,000 customers may be entitled to a Guaranteed Service Level payment in the 2022-2023 financial year relating to supply restoration and low reliability service levels set by the Electricity Distribution Code of Practice.
The AER defines:
- an urban feeder as a high-voltage circuit with load density greater than 300kVA/km. Covers outer metropolitan suburbs and major towns
- a short rural feeder as a high-voltage circuit which is not an urban feeder with total length less than 200 km. Covers rural areas near major towns
- a long rural feeder as a high-voltage circuit which is not an urban feeder with total length greater than 200 km. Covers remote rural areas.
