Network performance

While the reliability performance of our network is already high, we’re always trying to make it better.

Improving the reliability of our network is one of the main reasons we come to work each day. CitiPower has the highest reliability performance standards of any urban electricity network in Australia (based on the Australian Energy Regulator’s report), so we’re already doing well.

But there’s always room for improvement. So we’re constantly looking at how we can continue to provide a high quality service to a growing population, and then make it even better.

2017 CitiPower Reliability Targets

CitiPower provides a highly reliable electricity supply to more than 329,000 customers in Melbourne’s central business district and inner suburbs. This is a proud record and we are working with the Australian Energy Regulator (AER) to make ongoing improvements to our service delivery.

The targets for service reliability that have been set for us in 2017 by the AER are summarised below.

For 2017 CitiPower estimates that 300 customers will be eligible for supply restoration and low reliability payments as per section 6.3 of the Electricity Distribution Code.

The targets are based on average performance across the network, therefore some customers may receive a level of service above or below average targets.

While the reliability performance of our network is already high, we’re always trying to make it better.

Improving the reliability of our network is one of the main reasons we come to work each day. Powercor is one of the highest reliability performing rural electricity networks in Australia (based on the Australian Energy Regulator’s report), so we’re already doing well.

But there’s always room for improvement. So we’re constantly looking at how we can continue to provide a high quality service to a growing population, and then make it even better.

Although Powercor strives to deliver a high level of reliability to customers, occasionally we may be unable to meet your expectations. Powercor is required by section 6.3 of the Electricity Distribution Code to pay compensation to our customers if we fail to meet certain specified service levels. In 2017 Powercor anticipates making the following number of payments to our customers.
