Invitation to comment: Credible Event Review (CER)

Closing date for submissions 5:00pm, Monday 30th April 2018

Transpower have reviewed the scope of the Credible Event Review (CER) as part of its responsibility under the Policy Statement. We extend the opportunity for participants to provide comment on the outcomes of the scope review and the proposed assets which we have identified as needing further assessment. General feedback on any changes is also welcome.

The Scoping document includes:

  • Detail of the changes to the approach the System Operator has taken for this CER and intends to take for future reviews.
  • An environmental scan and a comparison of asset fault statistics to determine if a detailed power system and economic assessment are required for event classification.

The following document is available for your information/comment:
