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.
