Credible Event Management Review

Objective

The objective of this project is to review credible events as detailed in clause 12 of the Policy Statement, (Schedule C4, Part C of the EGRs) their categorisation and the operational measures to manage them to ensure the System Operator continues to comply with the Principle Performance Obligations.

The analysis will consider the likelihood of an event occurring, the means of managing the event and the relative cost of managing the event.

Any proposed changes to Credible Event Management will be included in the Policy Statement submitted to the Electricity Commission in early 2010.
