Those functions were previously specified in the TNSP Operating Agreements.

The instruments of delegation in each of the NEM Regions are as follows:

  • Victoria - 12 August 2013
  • South Australia - 14 December 2013

Under these arrangements, specified power system security responsibilities are delegated to each of these TNSPs in accordance with NER clause 4.3.3 through Instruments of Delegation and details are incorporated in each of the relevant Regional Power System Operating Procedures.
