Approved Targets for Power and Water Corporation (Networks) 2019-20 to 2023-24

​Under clause 3 of the Electricity Industry Performance Code (EIP), the Commission has approved new performance targets for Power and Water Corporation’s (PWC) network business for their next determination, from 2019-20 to 2023-24.

On 25 October 2017, the Electricity Standards of Service Code was formerly updated and merged with the Guarantee Service Level Code to form a new EIP Code.   As per the ESS Code, the EIP Code requires network licence holders (i.e. PWC) to submit for approval performance targets for their regulatory determinations. However, the EIP Code changed the definition for urban feeders, resulting in changes to the list of feeders classified as urban and rural short feeders. Thus the current targets are not directly comparable to the new targets.

Additionally, the new EIP Code does not require separate reporting on feeders used as transmission lines.  Therefore, transmission lines will now be absorbed into distribution feeder reporting.

The Target Methodology

PWC is required to propose targets based on System Average Interruption Duration Index (SAIDI) and System Average Interruption Duration Index (SAIFI) performance standards. SAIDI is an index showing the length of time customers are without power and SAIFI is an index showing the frequency of power interruptions to customer’s power.

For both performance indicators, the lower the better.

Table 1 sets out the approved performance targets.
