Asset Owners are obliged to complete a relevant ACS whenever commissioning/decommissioning or modifying their assets.  To get a better understanding of the general Asset Capability Information requirements before completing one, refer to the following document.

Urgent Asset Capability Changes

An Asset Owner may need to urgently or temporarily change an asset capability when they:

  • unexpectedly become aware that the capability of an asset may differ from the capability described in the most recent asset capability statement that has been provided to the System Operator; and
  • determine it is not practicable to submit a new asset capability statement; and
  • need to perform further investigations to determine or confirm the actual capability of the asset.

The following steps are to be taken by the Asset Owner once the asset capability change has been identified:

  1. Verbally notify the Energy Co-ordinator on 0800 535 123
  2. Download and complete the Urgent Asset Capability Change Form  (MS Word and PDF versions are available below) then send to system.operator@transpower.co.nz

Notes

  1. The asset capability information provided on the Urgent Asset Capability Change Form is a temporary asset capability change and is only valid for the duration notified on the submitted form.  Asset Capability information will revert back to the formally advised ACS information once the duration on the submitted form has passed. 
  2. For temporary changes longer than one week a formal change to the ACS must be submitted.
