RELIABILITY

 

We aim to provide you with the highest standard of electricity supply reliability and customer service. We are committed to continuously improving reliability of supply to customers within our network and seek to outperform reliability targets. We have been working hard to improve the reliability and safety of the electricity network.

 

Electricity reliability measures

In accordance with the requirements of the Australian Energy Regulator (AER) and as part of our commitment to customer service, we’re aiming for the following targets:

 

Measure for 2016

Supplied by  Urban feeder #

Supplied by Short Rural feeder #

Supplied by Long Rural feeder #

On average, the number of minutes a customer will experience loss of supply due to unplanned interruptions per year.
(eg. lightning, storm, fauna) (USAIDI)

 82 mins  189 mins  235 mins

On average, the number of unplanned interruptions a customer will experience per year (longer than one minute).(USAIFI)

 1.11  2.30  2.83
On average, the duration of an unplanned customer interruption (UCAIDI) 74 mins  82 mins  83 mins
On average, the number of momentary interruptions (less than one minute) (MAIFI) 2.80 5.83  11.38
 

We aim to maintain a high level of reliability. In the event that we do not meet reliability thresholds established by the AER, some customers (approximately 50,000) may be entitled to Guaranteed Service Level payments under clause 6.3 of the Electricity Distribution Code. If you would like to know more, please contact us.
 

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 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 more remote rural areas
