Extension of Contestability

A number of Extension of Contestability Agreements (EoC’s) are available to carry out additional works in relation to Competition-in-Connections activities.  The available EoC’s are listed below and, where available, can be selected to view an example agreement:

Self-Approval of Design

In some instances, ICP's and IDNO's can determine their own Point of Connection (POC) in place of applying to WPD for a POC.

The table below identifies the Market Segments within which the ICP/IDNO can determine their own Point of Connection:

In some instances, ICPs and IDNO's can self approve their own design, subject to the qualifying criteria to reach self inspection level. The table below indicates the Market Segments within which the ICP/IDNO can self approve their designs:

An audit process is in place to ensure that designs are compliant with WPD policies and standard techniques.

The table below identifies the qualifying criteria that will apply to allow an ICP/IDNO to move between the different levels of design approval:

Level

Criteria

1100% Audit, 20 audits to move to level 2
250% Audit, 20 audits to move to level 3
325% Audit
Self-audit level 15% Audit, 20 audits to move to self-audit level 2
Self-audit level 22% Audits

Further details on self-determination of a point of connection and design self-approval can be found within the standard techniques which can be accessed via the Technical Information page.
